PRECISIONFAB™ Belt Products
Engineered for performance in the most demanding belting applications, Premium PRECISIONFAB™ Belts deliver the best release, highest dielectric strength, and greatest chemical resistance of any Precision Coating PTFE belt. An extremely smooth, non-stick surface is applied over a woven fiberglass substrate and designed to keep fabric impressions to an absolute minimum. Our Premium Belts are excellent for use with sticky or gummy materials, and for process applications requiring an extremely smooth surface.
The workhorse of Precision Coating’s belting line, PRECISIONFAB™ belts were created to deliver the best possible balance of performance in heat transfer, release, flexibility and overall value. Each belt is manufactured from woven fiberglass substrates with an optimal PTFE content, and designed to leave a minimal fabric impression.
Our anti-static belts are specially formulated to dissipate surface static build-up in conveyor applications. Their formulation includes a proprietary additive that dissipates static, a black color and a strong woven fiberglass substrate with optimum PTFE content. Anti-Static PRECISIONFAB™ Belts are best used in applications where static is a significant operational concern, including garment fusing and fabric lamination. In addition, Anti-Static has the highest thermal conductivity of any PRECISIONFAB™ belt product.
Formulated to allow curing and outgassing through the fabric, porous PRECISIONFAB™ belts perform without sacrificing their unique non-stick properties. Each belt is manufactured from a woven fiberglass substrate coated lightly with PTFE. This controlled porosity is well suited to a wide variety of applications, including the manufacture of sponges, foams and wood laminates.
Specially processed to increase flexibility and prevent tearing, PRECISIONFAB™ Tear Resistant Belts are Precision Coating’s strongest, most durable line of PTFE coated fiberglass belting. The belt’s coating blends optimal PTFE content with a proprietary additive that maximizes flexibility. The coating and woven fiberglass substrates are formulated to leave a minimal fabric impression. Applications for PRECISIONFAB™ Tear Resistant Belts include small pulley and high-speed packaging machinery.
PRECISIONSIL™ Silicone Belts
PRECISIONSIL™ is the most conformable, flexible, trackable, and wear resistant belt offered by Precision Coating. This series is made from woven fiberglass substrates that have been coated on one or both sides with silicone rubber, yielding a belt with dimensional stability, durability, excellent tensile strength and low elongation. These belts provide surface friction that is much higher than the surfaces of a belt coated with polytetrafluoroethylene (PTFE), yet retain comparable release characteristics. In fact, some products that may adhere to PTFE coated fabrics may not adhere to silicone coated surfaces. Choose any of PRECISIONSIL™ Silicone Belt colors (red or white) for use where a surface grip with excellent release is desired. PRECISIONSIL™ is FDA compliant (21 CFR 177.1550) for use in food processing, packaging and handling. Use PRECISIONSIL™ in shrink tunnels, slightly inclined conveyors or other applications where both a strong surface grip and excellent release characteristics are desired.
PRECISIONMESH™ Open Mesh Belts
Applications requiring superior air and heat transfer can benefit from the use of PRECISIONMESH™ Open Mesh Belts. Air flows readily through the ¼” open weave of PRECISIONMESH’s woven fiberglass substrate, making it ideal for use in heat tunnels and process freezing applications. Highly resistant to most chemicals, PRECISIONMESH™ maintains dimensional stability from -100° to +550°F (-73° to +288°C).
Especially suited for food preparation, PRECISIONWEAR™ belts are manufactured using a non-metallic copper colored pigment, and reddish brown pigments. Made from a very tightly woven fiberglass cloth that has been heavily coated with PTFE, the final product has a very smooth, pinhole free surface with an enhanced abrasion resistant coating. Temperatures range from -100° to +550°F (-73° to +288°C). PRECISIONWEAR™ Belts are FDA compliant (21 CFR 177.1550) for use in food processing, packaging and handling.
PRECISIONFAB™ Porous Belts are used to apply synthetic rubber backing to carpeting. Our PTFE-coated fiberglass conveyor belts convey the uncured synthetic rubber backing through the manufacturing process. The woven fiber (carpet) overlay is bonded to the uncured synthetic rubber as the PTFE coated fiberglass belt conveys it through a curing oven. The PTFE conveyor belt’s non-stick properties allow for an excellent release of the cured and bonded synthetic rubber. PRECISIONFAB™ Porous Belts are designed to imprint the pattern of the belt’s finish on the rubber backing. PTFE coated fiberglass products can be supplied in roll form, slit to size or as a finished belt. They are also available in a smooth finish.
Screen-printing and graphic arts represent a large market for PRECISIONFAB™ Porous & Open Mesh belting products. Screen printers need a tough, durable belt to convey printed products through a drying oven. Typical screen printing applications include:
- Tape for Silkscreen table covers
- Print dryer belts for T-Shirts / Paper/ Card / Metal / Wood / Glass / Plastic Parts
- Feed and take-off belts
- Belts for conveying printed circuit boards through inking or soldering processes
- Lower Maintenance Costs: non-stick PTFE belts are easy to clean
- Energy Savings: PTFE belts provide better heat transfer and absorb less energy
- Cost Savings: A PTFE belt costs less to purchase. Its low relative mass allows it to function in a simpler, less expensive pulley and drive system
How to Measure Belts
We prefer the original equipment manufacturer’s specified dimensions for your existing conveyor belt; if this is unavailable the procedure below can be used to determine conveyor belt dimensions.
Please be careful when measuring a used conveyor belt. Existing belts may be stretched or skewed, making measurements inaccurate.
To Determine Conveyor Belt Dimensions:
- Measure belt width, edge to edge
- Measure belt length
If the existing belt is in good condition:
- Lay belt on the floor and measure from end of the belt to the other.
If the existing belt is badly deteriorated:
- Center the take-up pulley and measure the path of the belt through the dryer using a tape measure
A number of splicing options are available to suit a wide variety of application requirements.
- Metallic Splices: Clipper & Alligator
The most durable splice, and the easiest to use. An alligator or clipper type lacing is locked into reinforced belt ends. The laced ends are then meshed and joined together by a pin. A coverflap can be added to these splices to reduce mark-off and heat transfer to your material.
- Non-Metallic Splices
A softseal splice or notched splice is perfect when metal lacing cannot be used. The notched splice is effective when a very smooth release surface is needed.
- Endless Splices
Butt splices and overlap splices are all made to be endless. Endless splices are available in multiple widths and angles.
- Edge Reinforcements
Precision Coating offers a wide range of edge reinforcements for belting and fabricated parts. In addition to protecting the fabric edges from wear, abrasion, and snagging, these reinforcements strengthen the edge so that it can support guide strips, dots, and other guiding and tracking devices.
To assure the best performance and accurate tracking, we recommend ordering PRECISIONFAB™ BELTS with splices wherever possible. We offer all the standard splices. The Precision Coating technical service department can help determine the best splicing option for your specific application.
HEAT SEALED OVERLAP
This is the standard splice for most applications. The belt ends are overlapped from 1/2" to 2" then heat sealed. The splice can be stitched for additional strength.
HEAT SEALED BUTT
This splice is perfect in applications where a smooth belt surface is required. The ends of the belt are butted together. A reinforcement fabric is positioned beneath the joint, then heat sealed into place. For additional strength this splice can also be stitched.
A finger splice provides an excellent continuous release surface. Die Cut interlocking fingers are joined, reinforced and heat sealed into place.
An exceptionally strong metal splice, formed by metal lacing that is meshed together and joined by inserting a metal pin. This flexible splice enables a belt to be installed without taking the machine apart.
FABRIC PIN SPLICE
Similar to the Alligator/Clipper splice but without any metal components.
