Features of the PS Sheet Extruder Machine
PS material's high melting point and high crystallinity require targeted optimizations based on standard POK sheet extruders, primarily in terms of temperature control accuracy and plasticizing efficiency.
1.PS Sheet Extruder Machine ：High-precision temperature control, adapted to POK material characteristics
PS material has a melting point of approximately 220-230°C and is sensitive to temperature fluctuations. Multi-stage temperature control is required to ensure melt stability.
The barrel utilizes multiple independent heating and cooling systems, achieving a temperature control accuracy of ±1°C, preventing localized overheating and material degradation.
The die head (especially the coat-hanger die) utilizes a zoned heating design, achieving temperature control accuracy of ±0.5°C, ensuring uniform transverse sheet thickness.
Some high-end equipment is equipped with a melt temperature sensor, providing real-time feedback and temperature adjustment, further minimizing the impact of temperature fluctuations on the product.
2. PS Sheet Extruder Machine ：Efficient plasticizing and stable extrusion ensure continuous production
PS material has a high viscosity, requiring enhanced shearing and conveying capabilities. Therefore, the equipment features specialized optimizations in the screw and extrusion system. The screw utilizes specialized flight structures (such as barrier and separation screws) to enhance shear mixing of the POK melt, ensuring full plasticization of the raw material and reducing unmelted particles.
A high-precision melt metering pump is standard, precisely controlling melt output, enabling sheet thickness tolerances to be controlled to ≤±0.05mm and improving extrusion stability.
The screen changer utilizes a fast screen change design (such as hydraulic automatic screen changer) to minimize melt pressure fluctuations during screen changes, avoiding product scrap caused by screen changes and ensuring continuous production.
3.PS Sheet Extruder Machine ：Highly automated integration reduces operational barriers and costs.
Automated control reduces manual intervention, improving production efficiency and consistency.
