Solid Metal Belt for Plastic Pellet Extruder

Belt Technologies was recently approached by a customer that produces plastic pellets for recreational and automotive components. The pellets were made by extruding hot, melted plastic onto a conveyor belt which would then be transported to the next production phase while it cooled.

The original conveyor system used a basic mesh metal belt to transport the resin pellets after they were extruded. Unfortunately, the surface texture of the mesh metal belt was leaving undesired impressions on the plastic as it cooled. The customer came to the experts at Belt Technologies seeking a solution that could improve their system’s product handling.

Replacing Mesh Metal Conveyor Belts

The customer wanted proof of concept before investing in an entirely new conveyor, so they designed a belt that could be retrofitted to their existing conveyor system. Belt Technologies has experience with these types of customer requests, and we were able to advise them that replacing the belt would be a satisfactory solution to their problem. Our team visited the customer at their facility to survey the system and ensure that a replacement conveyor belt would be possible. To replace the mesh metal belt, our experts determined the original pulleys were too small and would need to be replaced with drive pulleys. In addition, due to the restricted size of the system, the new belt would need to be welded in place, rather than being welded first and installed after the fact.

The plastic would be extruded onto the belt at temperatures ranging from 500°F to 600°F. The new belt would need to be able to withstand these elevated temperatures. The unique properties of stainless steel make our endless metal conveyor belts an ideal choice for applications dealing with high heat. They are resistant to extremes in temperature and will not warp, even with continuous exposure, enabling them to last much longer than conventional conveyor belt materials.

Achieve Superior Product Quality and Throughput

Endless metal conveyor belts from Belt Technologies have a flat, impermeable surface which makes them the best option for applications that need a smooth product finish. They are made from a flat sheet of stainless steel, rather than a series of links and chains like mesh metal belts. We produce endless metal belts by welding stainless steel into a continuous band. Our welds are seamless and incredibly strong—achieving flawless welds when working with thin stainless steel belts is our specialty.

To install the new replacement belt, it would need to be welded in place on the existing system. Our team has the ability to weld belts onsite if necessary, however, the customer was willing to send their entire system to Belt Technologies to complete the installation. With the new, smooth metal belt from Belt Technologies successfully installed, the customer was able to achieve the perfect product results they were looking for.

Conveyor System Upgrades to a Stainless Steel Belt for Perfect Product Handling

Belt Technologies engineers have the knowledge and experience to not only design and build brand-new, custom conveyor systems, but also to retrofit existing conveyor systems to take advantage of the unique properties of stainless steel metal belts. When a customer contacts us with a problem regarding their existing systems, we are more than ready to examine their specific needs and provide a solution.

Product Manufacturing Requires Specialty Belts

A customer recently contacted Belt Technologies for a solution to a product-handling issue. They produced high-performance plastics and resins, which were being extruded onto a conveyor belt at high temperatures and allowed to cool as they were transported. The original conveyor belts were mesh metal belts; these were able to handle the high temperatures of the extruded plastic material but would leave markings on the plastic strands as the material cooled. The customer needed a new conveyor belt that could withstand elevated and varied temperatures without leaving any markings on the finished products.

Mesh or Flat Metal Belts: Which Do I Need?

The smooth finish of flat metal conveyor belts ensures there are no unwanted marks or dents on finished products.

Flat metal belts are durable and easy to clean. Their resistance to high heat makes them a great choice for applications using elevated temperatures. Unlike mesh metal belts, our flat metal conveyor belts are made from a single sheet of high-end stainless steel. Endless metal conveyor belts from Belt Technologies have a flat, even surface, which makes them ideal for applications that need a smooth product finish.

Mesh belts are another form of metal conveyor belt often used in high-heat applications. They are made of links, or metal weaves that allow the passage of fluids or air. While popular, the challenges and shortcomings of mesh belts can be detrimental to a production line. Hundreds or even thousands of links mean hundreds of difficult-to-clean recesses, making mesh belts a haven for contamination. Any misalignment of a mesh belt can result in damage to individual wires and links, making the risk for belt failure or damage to product significantly higher and increasing the potential for downtime. As demonstrated in this specific instance, the textured surface of a mesh belt can also result in damaged product that must be reworked or scrapped altogether. An upgrade to an endless, solid metal belt can eliminate many of the expensive risks associated with mesh belted conveyors.

Avoid Complete System Replacement with Affordable Retrofit Solutions from BTI

Belt engineers worked with the customer to design a new, flat metal conveyor belt that would easily integrate into the existing conveyor system. The new belt was made with 301 full hard-tempered stainless steel able to withstand the high temperatures required for the operation. The flat surface will not leave any marks on the extruded plastic as it cools.

With a retrofit solution from Belt Technologies, the customer was able to avoid the cost of replacing the entire system and can now achieve the smooth product results they needed.
