The hydraulic slide plate screen changer features a solid main body with a sliding plate inside. Multiple screen positions that are arranged within the unit allows one screen to remain in operation while the other stays on standby. By switching between the two, filtration continues without stopping extrusion This screen changer is widely used for variety of materials, including PP, PE, PS, and ABS, as well as certain engineering plastics and rubber compounds. It is commonly used in extrusion and pelletizing lines where stable melt filtration is required.

Features
- A full metal sealing structure is used to prevent melt leakage during operation.
- Key pressure-bearing components are made from high-strength alloy steel. It can handle working pressures of up to 35 MPa.
- Pressure and temperature sensors monitor melt pressure and sealing condition in real time.
What monitoring options help keep melt pressure stable during filtration?
What monitoring options help keep melt pressure stable during filtration?
The screen changer can be equipped with a pressure sensor to track melt pressure at the die head in real time, which helps maintain stable extrusion. A temperature sensor is also included to keep the die at a steady temperature, supporting consistent melt pressure during operation.
