Tungsten Carbide MDO Stretching Heating Roller
High Hardness Reduces Maintenance Costs
Tungsten Carbide Stretching Rollers for BOPP Film are essential components in the production of BOPP (Biaxially Oriented Polypropylene), BOPET, and BOPA films. These precision rollers perform critical stretching operations that enhance film mechanical properties and performance.
Key Features and Benefits:
- Material: Tungsten carbide construction provides exceptional durability and wear resistance for demanding BOPP film stretching applications.
- Hardness: 85-95 HRA (Rockwell A scale) ensures superior resistance to wear and abrasion.
- Surface Finish: Precisely engineered surface delivers optimal grip and traction during film stretching.
- Thermal Conductivity: Efficient heat transfer properties enable effective film cooling during stretching processes.
- Dimensional Stability: Maintains precise shape and size under extreme pressures and temperatures.
- Extended Service Life: Exceptional wear resistance significantly reduces downtime and maintenance expenses.
- Film Quality: Ensures uniform stretching and thickness distribution for consistent, high-quality BOPP film production.
