Tungsten Carbide MDO Stretching Roller High Hardness Reduce Maintenance Cost
MDO Stretching Roller Introduction:
Tungsten Carbide Stretching Roller For BOPP Film are commonly used in the production of BOPP (Biaxially Oriented Polypropylene), BOPET, BOPA films. These rollers play a crucial role in the stretching process, where the film is elongated in both the machine and transverse directions to improve its mechanical properties and performance.
MDO Stretching Roller Features and Benefits:
1. Material: Tungsten carbide is a highly durable and wear-resistant material, making it ideal for the demanding conditions of BOPP film stretching.
2. Hardness: Tungsten carbide rollers have a high hardness level, typically ranging from 85 to 95 HRA (Rockwell A scale), which ensures excellent resistance to wear and abrasion.
3. Surface Finish: The surface of tungsten carbide rollers is carefully engineered to provide the desired level of grip and traction on the film during the stretching process.
4. Thermal Conductivity: Tungsten carbide has good thermal conductivity, allowing for efficient heat transfer and cooling of the film during stretching.
5. Dimensional Stability: Tungsten carbide rollers exhibit excellent dimensional stability, maintaining their shape and size even under high pressures and temperatures.
6. Extended Service Life: The exceptional wear resistance of tungsten carbide stretching rollers results in a longer service life compared to other roller materials, reducing downtime and maintenance costs.
7. Improved Film Quality: The use of tungsten carbide rollers helps achieve uniform stretching and thickness distribution, resulting in high-quality BOPP film with consistent mechanical properties.
