Have you ever had to toss out a whole batch of parts or components due to rust?

 

As a manufacturer, it’s on you to deliver parts and components that are strong, safe and corrosion-free...which can, unfortunately, force you to scrap parts or components affected by rust at your own expense.

 

It’s common knowledge that metals containing iron or steel are susceptible to corrosion. You’ve seen firsthand how a batch of components left exposed to air, moisture and oxygen can develop a layer of rust in no time.

 

The longer the exposure, the faster the process of oxidation occurs, especially under humid conditions!

 

Faced with this challenge, manufacturers like you trust Latem Industries to effectively remove rust and ensure manufactured parts perform better for longer. Here, we’ll review the advantages of vibratory finishing for rust removal by Canada’s Mass Finishing Experts!

 

Vibratory Finishing ‒ a Powerful Rust Removal Solution

 

Vibratory finishing processes are terrific for improving the surface of metal and removing dangerous burrs or sharp edges.

 

In addition to improving their safety and performance, vibratory finishing is highly effective at removing rust from manufactured parts or components.

 

Because it is a mass finishing process, vibratory finishing is a cost effective way to improve and protect large quantities of parts at the same time.

 

How Vibratory Finishing Removes Rust

 

Vibratory finishing processes consist of an operation in which cleaning compounds and specially-shaped media, along with rust removal compounds, are placed into a massive vibratory bowl. The size of the bowl can range from single-digit cubic foot machines to massive units well over 100 cubic feet! The rusted parts or components are then added into the bowl.


As the vibratory process begins, the machine and its contents vibrate at an accelerated rate (in the range of 900 to 3,600 vibrations per minute.) The vibratory action causes the contents of the bowl to move in a corkscrew pattern, pushing the finishing media up against the parts and components. As the parts or components brush up against each other and the media, their surfaces are cleaned of dirt, oil and rust.

 

Through proper process and media selection, it is feasible to finish a massive volume of parts in a relatively short period of time. Vibratory finishing is by far one of the most efficient and effective ways to remove rust in big batches!

 

In terms of its intensity, vibratory finishing falls somewhere between barrel tumbling and centrifugal finishing. Since there is no tumbling of parts, the process is a bit less aggressive (although no less effective) than tumbling. Vibratory finishing is ideal for parts and components made of softer metals that would be susceptible to distortion or stresses in a tumbling process.

 

Once the process is complete and the rust is gone, special rust inhibitors are added to the vibratory bowl to ensure the parts and components are protected from recurring corrosion.

 

The Best Way to Eliminate Rust

 

Left unchecked, rust can quickly and seriously compromise the safety of any structure, vehicle, or machines with iron or steel components.

 

Corrosion causes a weakening of parts as it slowly eats away at and degrades the strength of the steel. It also negatively impacts the painting or coating of steel due to a lack of adhesion on the unstable, rusted surface.

 

That’s why manufacturers like you turn to Latem Industries. We have lent our rust removal expertise to countless industries over the years, including manufacturers of automotive, sports and fitness products. Our ability to process several thousand parts at once means the cost to remove rust is negligible on a per-piece basis.

Most people see a Plastisol-coated part and assume it was a simple thing to do.

 

Just a quick dip in a vat of liquid plastic and, like magic, the part comes out with a bright, flawless coating. Sounds easy, doesn’t it?

 

Well, like most things in life, coating parts in Plastisol isn’t as simple as it might appear! Few people realize the amount of work it takes ‒ not to mention the variables that must come into play ‒ to get the perfect coating.

 

In fact, it’s rare that any two components are coated in exactly the same manner!

 

Here are just a few of the questions you’ll need to answer (and trials to overcome) if you’re aiming to achieve the best Plastisol coating, including:

  1. Will the part be fully or partially coated?
  2. Which areas of the part must be coated?
  3. What thickness and hardness is required?
  4. What about colour?
  5. Any special end-use requirements?

1. Will the Part Be Fully or Partially Coated?

In a dip coating process, the component is attached to the equipment (either by hanging the component or fixing it to tooling) and then lowered into a bath of liquid Plastisol.

 

If the component is to be fully dip-coated, we need to know which area of the component will be allowed to have an uncoated touch mark or bare spot from the tooling used to hold it. This information determines how to hang the part for immersion.

 

Depending on the footprint of the equipment’s dipping area, the way in which we hang the component can greatly influence throughput and go a long way in determining the cost of Plastisol dip coating.

 

2. Which Areas of the Part Must Be Coated?

Along the same lines, we need to know which portion of the component will be coated and which will be exposed and which when the part is to be partially dipped. From there, it can be determined whether the best course of action is to:

 

Hold the component on the undipped area for immersion;
Trim Plastisol from the component after coating; or
Incorporate masking into the dip coating process.

 

Again, these factors go a long way in determining the cost to run the part!

 

3. What Thickness and Hardness Is Required?

Plastisol can be applied thick or thin, depending on the part’s application. Generally, the thickness achieved through a dip coating process ranges from 0.75mm to 2mm.

 

The formulation and curing process can be adjusted to achieve hardness ratings between 5 Shore A and 80 Shore D.

 

4. What About Colour?

Plastisol comes in a number of standard colours including black, red, white, blue, green and yellow. Since we make our own Plastisol in-house here at Plastico Industries, we can manufacture custom colors to suit your specific needs. This also lets us control the process from start to finish, cutting back both on waste and additional distribution channels!

 

5. What Will Be the Component’s End Use?

The remarkable durability of Plastisol coating makes it ideal for a huge variety of applications, from the eliminating BSR in the automotive industry to the military, agriculture, and even the home markets. Knowing the component’s eventual destination and use allows us to customize the substance to meet special requirements such as UV protection, food grade standards, and durometer requirements.

 

Other Dip Coating Trials and Tribulations

Once these basic questions are answered, we can come up with a process that will achieve the best possible results for the component in question. That’s where we really get down to business! Some of the other factors to consider when formulating a full or partial dip coating process include:

  • Drips: Depending on how the part is attached to the tooling, drips can occur during the dipping process. Before the process begins, it must be determined where on the component drips are acceptable and whether we can trim them off later.
  • Pooling: If the part is concave or cup-shaped, Plastisol can pool in the inward areas, where it will become too thick and not cure properly.
  • Tooling: Will the existing tooling work for this process, or will new tooling have to be made? This, too, will ultimately impact the process’s overall cost.
  • Curing: Parts must be preheated, dipped and then cured. The preheating and curing temperatures are determined based on the part’s raw material, size and thickness. If the product needs to be preheated for longer, or requires a longer dip time, this will shore up the cycle times and influence cost via throughput.
  • Packaging: Once the part has been processed, we need to know the packaging and labelling requirements. Will it require any special testing or certification?

All in all, it’s safe to say that the Plastisol coating process is not nearly as clear-cut as you’d think! There’s a whole lot you need to consider before, during and even after the component is coated.

 

That’s the advantage of having 20+ years in the business...we’ve seen it all, so we know exactly how to tackle the many trials, tribulations and pitfalls of Plastisol. Our team handles all the nitty-gritty details so you don’t have to!

Washing is a crucial step in the process of preparing parts for coating or welding. For many types of parts and components, ultrasonic cleaning is the safest and most effective way to get the job done.

 

However, since ultrasonic cleaning is just one of many different parts washing methods at your disposal, you’ll want to understand how it works before deciding whether it’s the best solution for you!

 

Here are our answers to the most frequently asked questions we get about ultrasonic cleaning: how ultrasonic cleaning works, when it’s ideal, and whether it’s really effective compared to the more heavy-duty alternatives.

 

What Is An Ultrasonic Machine and How Does It Work?

Ultrasonic machines use transducers and electric ultrasonic wave generators to generate high-frequency sound waves.

 

Typically, the transducers are made from piezoelectric crystals, which change in size when electrical voltage is applied.

 

These devices effectively convert electrical energy into mechanical/sound wave energy, which radiates through a cleaning tank or ‘tub’ in the ultrasonic machine.

 

How Does Ultrasonic Cleaning Work?

The high-frequency sound waves generated by the transducers and wave generators are transmitted in a liquid solution of water and solvent base, causing cavitation.

 

Cavitation is simply the implosion of the solution molecules resulting from the transmission of high-frequency sound (pressure waves) through them. This extremely high pressure variation over a very small area causes a great deal of agitation on the surface of parts submerged in the solution.

 

The surface agitation or “micro-scrubbing” in an ultrasonic cleaning system is highly uniform throughout the surface (including blind holes and part internals) since the agitation is formed in the solution in which the part is placed. This allows the part or component to be cleaned inside and out, regardless of its geometry!

 

To break it down step-by-step, the ultrasonic cleaning process goes like this:

 

  1. Place the part(s) you want cleaned into the tank of the ultrasonic machine.
  2. Fill the tank with enough liquid (water or a cleaning solution) to submerge the part(s).
  3. Close the tank and activate the ultrasonic machine.
  4. Inside, the transducers and electric ultrasonic wave generators cause the tank to vibrate and produce cavitation. This pressure forces dirt, rust and other contaminants loose from the part(s).
  5. About 5 minutes later, the tank’s contents are clean and ready to be coated!

 

Which Parts Are Ideal for Ultrasonic Washing?

Virtually any kind of part or component can benefit from ultrasonic cleaning, but it’s the more fragile or complex parts that were really made for this method.

 

Unlike vibratory or tumble cleaning, the gentle-but-thorough ultrasonic cleaning process does not force the parts into contact with one another. As a result, there is no change to the parts’ appearance or composition. Tumble cleaning and vibratory cleaning, on the other hand, are both purposely aggressive processes that benefit from the parts making contact with each other and/or the finishing media.

 

Ultrasonic wash is also ideal for single large components. At Latem Industries, our ultrasonic tanks can accommodate parts up to 4’ long and 2.5’ wide.

 

Can You Remove Rust With An Ultrasonic Wash?

Latem Industries has a proprietary process that allows for the removal of rust from parts or components using ultrasonic wash. As rust or corrosion can occur on virtually any part, the ultrasonic wash quickly and efficiently removes rust from fragile parts or those with complex geometries.

 

In fact, ultrasonic cleaning not only removes corrosion, but also completely neutralizes rust, returning the parts to their original, perfect finish!

3D printing, once considered the stuff of science fiction, is finally here! The potential applications of 3D printing are practically endless: from modeling and prototyping to direct production of custom parts.

 

But there’s an important catch: almost all 3D printed parts require some secondary finishing before the part is ready for its next stage.

 

The truth is, 3D printing is still in its infancy. It needs some help in order to truly be viable for mass production. And Latem Industries, always looking forward, is here to assist!

 

3D Print Finishing: Smoothing, Refining and Adjusting

The 3D printing process builds a three-dimensional object from a computer-aided design (CAD) model, usually by successively adding material layer by layer. This is also known as additive manufacturing, in contrast to subtractive manufacturing (CNC machined parts).

 

These parts are usually manufactured in small batches, in a relatively quick time frame. The parts can range from basic shapes to intricate patterns. 

 

 Finishing may be required to:

  1. Change the appearance of the surface
  2. Smooth out the surfaces of the part
  3. Improve its life cycle
  4. Adjust size and shape

What’s The Best Way to Finish 3D Printed Parts?

There are multiple methods or techniques that can be used on 3D printed parts.  The best method depends on the raw material of the part, the requirement needed and pricing.  Latem Industries offers several different processes to finish 3D printed parts.

 

1. Shot Blasting

Most companies use manual sanding to smooth out the surface of a 3D printed part. However, this is not very time efficient, nor can you sand interior or hard-to-reach areas 

 

Shot blasting is a much quicker, more thorough option that can easily reach difficult areas. In a shot blasting process, the 3D parts are placed in a chamber and blasted with small particles. The particles gradually smooth out the parts’ surfaces and remove rough edges.

 

Blasting will give you a uniform finish with a matte surface. Blasting also increases adhesion of coatings that may be applied to the 3D part. 

 

2. Shot peening

Similar to blasting (and often done using the same shot blasting machines) shot peening will strengthen the part and help to extend its expected life cycle. 

 

Shot peening removes tensile stress and replaces it with compressive stress, making the surface stronger. Imagine a blacksmith hammering a metal object, i.e shield, sword or horseshoe. This is how peening was performed manually! 

 

In a shot peening process, the 3D printed parts are bombarded with smooth, round shots that act as tiny ball-peen hammers. Gradually, the surface of the parts become stronger and more resistant to cracks or fatigue. We can also use shot peening to give the parts a textured surface.

 

Latem has machines to do this automatically, shortening process times, which in turn reduces cost.

 

3. Vibratory Finishing

Vibratory systems allow you to process and polish small or delicate 3D parts singularly or in batches.

 

In a vibratory finishing process, the 3D printed parts are placed in a large bowl containing abrasive media and cleaning agents. The bowl vibrates to agitate the media while rotating in a circular motion. This gentle motion polishes the parts while smoothing their edges and surfaces.

 

Depending on the raw material, it is possible to polish your 3D printed components to a very shiny or even mirror-like surface!

 

4. Tumbling

Tumbling is ideal for small 3D-printed parts post-processing. In a barrel tumbling process, the 3D printed components are placed in a large barrel that also holds abrasive media and cleaning agents. Multiple parts are run at once, gently rubbing against one another, or other media, resulting in a smooth finish. 

 

The benefits of tumbling include speed, consistency and versatility: depending on your choice of abrasives and media, it can be used to produce a wide range of finishes. The process can take minutes up to hours depending on the product and the finish required.

Vibratory Finishing is a generic name given to the process of improving the surface of metal using vibrational forces. This process is highly effective in removing burrs or edges (deburring)  from metal components that appear after stamping or forming. removing sharp edges.

 

Vibratory finishing can also be used to clean and polish metal surfaces before the parts are coated or delivered to your customer.

What is a Burr or Edge?

A burr is a ‘leftover’ piece of material that protrudes from an edge of a metal component after machining (grinding, milling, stamping, turning, etc.)

 

Burrs are known to cause numerous problems for manufacturers: interfering with edge fitting in product assembly, jamming along the assembly line, increased wear on parts, improper seals where edges meet, and safety concerns for workers who handle the parts along the line.

 

Needless to say, burrs are a persistent thorn in the manufacturing industry’s side!

 

3 Common Types of Burrs (Edges)

Unfinished parts often come off the line with sharp edges, rough surfaces, and protruded metal burrs in corners and on edges. These burrs come in many shapes and sizes ‒ some even too small to see with the naked eye (and impossible to fix manually!) Whether large or small, burrs or sharp edges are a significant quality concern as they compromise the performance of the part or component.

 

The following are the most common types of burrs that can appear on a formed or machined metal parts:

 

  1. Roll-over burr: One of the most prominent types of burrs, a roll-over burr is an unwanted piece of material at the end of a cut. Roll-over burrs form when material is pushed out of the tool’s path instead of being sheared off. They are more likely to occur on pliable or ductile metals, like copper, especially when the cutting edge is dull.
     
  2. Poisson burr: Named for Poisson’s ratio, a Poisson burr occurs when metal bulges outward under the strain of the cutting or forming, creating a raised edge rather than a smooth cut. It often appears when turning or drilling a part or component.
     
  3. Tear burr: As the name implies, a tear burr is material that tears loose from the part or component. A dull blade or a die in need of repair is a common culprit of tear burrs, as the metal wraps around the dull corner and tears. Tear burrs most often occur in punching operations.
     

Vibratory Deburring: How it Works

First, the products are placed in a large vibratory bowl with a capacity of up to 100 cu. ft. The bowl is partially filled with media, which is the name given to particles in the vibratory chamber. The media may be comprised ceramic pre-formed shapes incorporating abrasive particles or polishing agents to improve the surface finishes of the metal components introduced into the media.

 

When in operation, the machine generates vibrational forces by rotating an off-balance device at between 1,500 to 3,000 RPM. The rotator is bolted to the vibratory bowl mounted on coil springs or rubber mounts.

 

The result of the motor and spring arrangement will activate the media mass causing it to rotate within the vibratory bowl. This movement creates a “scrubbing” action, enabling the media to attack the metal components, thereby removing metal and creating a deburring effect on sharp edges produced when the metal components were formed or machined.

 

While vibratory finishing is most often used to break an edge or to deburr, it can also be used to produce a burnished, almost polished finish. This is achieved by changing out the ceramic media for porcelain, stainless steel balls or organic media.

 

Depending on the application, cycle times can vary from just fifteen minutes to several hours. With proper preparation and media selection, the parts should emerge from the vibratory finishing process unscathed, save for the removal of burrs. In general, vibratory deburring is gentler on parts than barrel tumbling.

BSR. This acronym can stand for many different things (over 50, in fact, according to Google.)

 

But in the automotive sector, it can mean only one thing: buzz, squeak and rattle. And 99% of the people who deal with BSR in this industry really wish they didn’t have to.

 

We happen to be among the 1% that don’t mind ‒ because we have the tools and expertise to eliminate BSR for good. Here, I’ll introduce you to three of the coating technologies we use to help automotive manufacturers eliminate buzz, squeak and rattle from their vehicles.

 

But first ‒ what exactly is BSR?

 

What Does ‘BSR’ Mean in the Automotive Industry?

Buzz, squeak and rattle (BSR) is a catch-all term for a variety of fiction-induced noises that can be produced by a vehicle. It’s one of the biggest challenges facing automotive engineers today, and the number 1 cause of consumer complaints about new vehicles.

 

Generally, BSR is the unintended outcome of two component surfaces coming into contact with one another:

 

  • Squeak is caused by a stick-slip action when one part moves against another other.
  • Buzz is caused by the structure or component itself as it vibrates against another surface.
  • Rattle is caused by a collision between two components.

 

These noises might also be characterized by a consumer as squeals, creaks, clangs or bangs. At any rate, they’re the last thing any new vehicle owner wants to hear on their first long trip.

 

The automotive industry has long recognized the importance of vehicle noise when it comes to customer perception. Not only are speaks, buzzes and rattles annoying, they can have a hugely negative effect on how customers rate a vehicle’s quality and dependability. No one wants to save up for a brand-new car only to find that it starts rattling the second you take it down an unpaved road!

 

When you put it this way, I think you can see why 99% of the people who have this particular issue would much rather not. That’s why numerous articles, videos and blog posts have been made about BSR and how to solve it. In fact, in 2011, someone wrote an entire 296 book on this issue, covering such areas as background theory, testing, analysis and elimination with chapters from leading experts in the field!

 

Now, I might not have written the book on BSR, but I can tell you about three of the ways we can help you solve it here at Plastico.

 

3 Ways to Eliminate BSR Using Coatings

One of the go-to solutions for eliminating frictional noise is to apply a protective coating to at least one of the surfaces responsible.

 

Anti-BSR coatings save manufacturers a lot of time and trouble by avoiding the need to use secondary measures like felt spacers and lubricants post-production.  With the right application and the correct choice of coating, we can effectively eliminate BSR for the entire life of the vehicle.

 

Plastico Industries offers three coatings that are excellent in removing BSR: nylon, Plastisol and Polyarmor. Each product has its own unique properties and potential applications.

  1. Plastisol Coating offers colour, comfort, electrical insulation, texture, gripping power, and resistance to acids, alkalis and oils. Plastico Industries is an industry leader in Plastisol dip coating for the automotive industry.
  2. Polyarmor Coating offers a wide range of performance attributes including impact and corrosion resistance as well as UV protection. Plastico offers Polyarmor dip coating.
  3. Nylon Powder Coating offers resistance to corrosion, abrasion and chemicals, with natural lubricity and noise-dampening qualities. At Plastico, we offer nylon dip and nylon spray options.

Plastico Industries has been making and applying plastisol for nearly 20 years.  Because we are so ingrained with the manufacturing of it, and the application of it, we often forget that many people are not really sure what plastisol truly is! Here’s a quick, clean primer on the plastic coating known as Plastisol. 


What Plastisol is Made Of


Plastisol is described as, “a suspension of PVC or other polymer particles in a liquid plasticizer.” Huh? 


Let’s put that in layman's terms.  


The first part of the equation is polyvinyl chloride, better known as PVC or vinyl. It’s a synthetic plastic polymer, meaning that it is a chemical, man-made plastic. 


PVC plastic is mainly derived from salt and ethylene. Its production consumes less energy and creates fewer emissions than many other plastic products. Many PVC products are manufactured to meet medical and food-contact standards set by the Environmental Protection Agency (EPA) or the U.S. Food and Drug Administration.


PVC is incredibly versatile. It can be made thick or thin, rigid or pliable, and in practically any colour imaginable. The properties of PVC and other synthetic polymers can be modified by combining them with other ‘ingredients’ or additives like plasticizers.


Plasticizers are substances added to materials to decreases their viscosity or thickness. Essentially, the plasticizer dissolves in the polymer and fills the space between the polymer particles, pushing them farther apart. This makes the PVC softer and easier to bend. 


The more plasticizer added, the more flexible the plastic becomes. By combining PVC particles with the right amount of plasticizer, the mixture can flow as a liquid. This liquid can then be applied to other materials through screen-printing/heat transfers, dip-coating or in molds!


You might remember how PVC's came under scrutiny a number of years back due to the presence of phthalates used in plasticizers. We recognized these concerns and switched to a phthalate-free plasticizer out of respect for our customers, end users and of course our employees. Today, Plastico Industries continues to produce a safer, phthalate-free Plastisol.


What Sets Plastisol Apart


Plastisol has many appealing characteristics that make it a top choice for coatings!

 

  1. Colour Matching – Since it’s made primarily from PVC, Plastisol can be matched to any colour you could ever need. Our most popular choices are black, red, blue, green and yellow, but Plastico can also manufacture custom colours in-house.
  2. Feel – Plastisol has a “warm to touch”, soft feel that is easy and comfortable to grip.  It is used to coat tool grips, bicycle handlebar grips, furniture handles, and even kid-friendly playground equipment. 
  3. Sound Deadening – With a soft, impact-resistant surface, Plastisol can reduce metal-on-metal sounds such as squeaks, buzz or rattle.
  4. Electrical Resistance – Plastisol has high dielectric strength and doesn’t conduct heat or electricity. It is often used as an insulator for electrical tools, sheathings and connectors on wiring and busbars.
  5. Chemical Resistance – Plastisol’s resistance to alkali and acid makes it ideal for racks and tooling that are exposed to chemical substances.
  6. Corrosion Resistance – Excellent for use on farm equipment, playground structures and other outdoor applications.
  7. Impact Resistance – Plastisol is tough! We can add hardening agents to produce Plastisol with a Shore durometer rating of up to 90.
  8. Wear Resistance – You’ll often find Plastisol coating components that are frequently manipulated such as latches and pull handles.
  9. Masking – Used as masking for other secondary coating applications.

How Plastisol Is Applied


Plastico Industries specializes in Plastisol dip-coating and molding. Another option is to dip a pre-made shape into the Plastisol, cure the Plastisol and then remove the Plastisol from the shape. Good examples of this are bicycle handles and caps. 

 

  • Molding – Molding can include pouring the Plastisol mixture into a mold, curing the Plastisol and then removing it from the mold.  This application can be used to make furniture feet, spacers, washers, plugs, fishing lures; the options are limitless.
  • Dip-Molding -  Dip-molding occurs when a part is dipped into Plastisol to put a coating over the part. The part must be preheated. This heat, along with the dip time, will determine the thickness of the Plastisol.  This pre-heated part is then dipped into Plastisol to coat it and then heat cured.

Shot blasting is a method of descaling, derusting and deburring unfinished metal components. It is often a necessary step prior to assembly, or finishing touches like painting or coating.

 

In a previous post, we looked at the difference between two common shot blasting machine configurations: batch finishing and continuous finishing systems. To summarize:

  1. Batch finishing involves processing a load of parts into the shot blasting machine at once, then pausing the machine to remove the finished batch and add the next volume.
  2. Continuous finishing involves loading parts at one end of a machine one-by-one without pausing the machine, then offloading them at the other end. Parts move continuously down the line until they’re finished.

In short, batch finishing is stop-and-go, while a continuous system can keep going on and on for as long as you’re loading new parts. It’s not a competition ‒ both methods have clear advantages in different applications. But when it comes to processing large orders, continuous finishing often has the edge in terms of efficiency.

 

Today, we’ll take a closer look at two types of continuous finishing systems we use to process thousands of parts a week here at Latem Industries: flat bed roller conveyors and overhead conveyors.

 

Flat Bed Roller Conveyor

 

In a flat bed roller conveyor system:

  1. Components are loaded onto a massive roller conveyor outside of the shot blasting machine.
  2. When activated, the roller conveyor moves components into the machine and through one or more shot blasting chambers.
  3. The parts are processed using a 360 degree shot blasting pattern, treating virtually every exposed surface.
  4. The parts exit onto another roller bed on the opposite end of the machine. There, the parts are removed.

 

Roller conveyor shot blasting systems are ideal for treating long, flat components prior to welding, cutting and machining operations. Large parts can be effectively descaled, derusted or deburred using a flat bed roller conveyor system. It can also be used to remove paint or for general surface preparation.

 

At Latem Industries, our roller conveyor can accommodate parts as large as 7 feet wide and up to 30 feet long. Its design allows us to process steel plates, profiles, cast iron and galvanized steel pipes, and rolled steel H-beams and I-beams for structural steel construction.

 

Overhead Conveyor

In an overhead conveyor system:

  1. Components are loaded individually onto large racks hanging from an overhead conveyor.
  2. The conveyor moves along a rail, carrying parts into the machine and through one or more blasting chambers.
  3. Parts are shot blasted in a 360 pattern for complete surface coverage.
  4. Finished parts exit the machine at the opposite end of the rail, where they are unloaded.

Unlike flat bed roller machines (which are ideal for flat pieces) overhead conveyors can handle large components with unusual or complex shapes. These systems can be used to remove rust or scale, recondition stamped metal, or prepare components after die casting.

 

At Latem Industries, our overhead conveyor can accomodate parts weighing anywhere from 10lbs to over 300lbs. We’ve found it ideal for castings, welded constructions, forged and stamped parts, and complicated forms like large springs.
