With STEELASTIC’s range of steel belt machines, businesses have a manufacturing process that is fully aligned with changing market needs for lower capital investment, multi-SKU capability, high levels of automation and traceability, reduced utility usage, and ease of operation.
Steelastic’s range of Classic Extruded Steel Belt Systems can produce steel belt & breaker for the following tire types:
- Passenger & Light Truck Tires (PCR & LT)
- Truck and Bus Tires (TBR)
- Off the Road Tires (OTR)
- Aircraft Tires
- Non-Pneumatic Tires
- Rubber Track
Superior quality advantages over alternative manufacturing methods:
- Precise belt width, gauge and edge straightness
- Highly accurate splice and belt angle
- Shortest compound heat history
- Precise cord placement with NO possibility of crossed wires
Why Use an Extrusion-Based Calenderless Steel Belt System?
There are many reasons to use a calenderless system when manufacturing steel belt / breaker:
Ultimate Flexibility
Our extruded steel belt systems allow for changes in finished belt angle, and width, in a matter of seconds. Changes in steel cord and compound can be achieved in under 20 mins. This provides the very high levels of flexibility demanded in the modern tire market, as the tire SKU count continues to rise.
Productivity
A single STEELASTIC extrusion-based steel belt system can manufacture over 4,000 PCR steel belted tires per day, of multiple different SKUs. Typically, two, three, or more systems are operated together, providing tire manufacturers with the perfect mix of high productivity and flexibility.
One Streamlined Process
Our extrusion-based systems are one complete process from creel to wind-up. This eliminates the need to handle and store semi-finished material as required by calendering and offline processing methods.
Enhanced Quality Control & Traceability
STEELASTIC Extruded Steel Belt Systems include a range of vision, thermal and laser product inspection technologies to ensure the highest quality product, along with full traceability to plant manufacturing systems.
