Services
Conveyor Belts
We fabricate industrial conveyor belts using advanced equipment and NIBA-certified techniques. Our belts serve mining, manufacturing, and recycling sectors with durable, splice-tested designs. Custom options include cleated edges and magnetic separator compatibility for specialized material handling needs.
Rubber Sleeves
Custom rubber sleeves and tapered connectors are engineered for material handling systems. Available in multiple compounds, our sleeves withstand extreme temperatures and abrasion while maintaining flexibility for applications in sand/gravel and food processing industries.
Gaskets
Precision-cut gaskets and O-rings meet unique sealing requirements across industries. We produce die-cut and hand-fabricated options using FDA-approved and industrial-grade materials, ensuring compatibility with chemicals, oils, and extreme temperatures.
Die Cutting
Die-cut rubber components provide cost-effective solutions for repetitive maintenance and high-volume orders. Capabilities include intricate shapes up to 24" wide, serving automotive, manufacturing, and food processing sectors with tight-tolerance parts.
Vulcanizing
Our vulcanization process creates durable rubber sheets and components through heat and pressure. This technique enables oversized material production and dual-durometer parts, supporting conveyor belt repairs and custom industrial applications requiring enhanced material integrity.
