1, the length-diameter ratio of screw is as high as L/D=45, which improves the plasticizing ability and quality of screw.

The feeding section should keep this part of cooling water circulating continuously to prevent the temperature from rising. Prevent raw materials from sticking, caking and blocking the feed inlet.

2. Butane input and butane pump: The butane pump is a high-pressure metering pump, which injects liquefied butane into the barrel at a high pressure of 10- 15Mpa, and a one-way valve is provided at the place where butane enters the barrel.

3. Shrinkage-proof agent input and shrinkage-proof agent pump: Shrinkage-proof agent pump sends shrinkage-proof agent into the barrel at the pressure of 10- 15Mpa. The feeding part is provided with a one-way valve. I hope I can help you!

4. Mold part: The melted raw materials are extruded from this part. As soon as the raw material passes through the die lip, it begins to foam. The thickness of EPE pearl cotton sheet depends on the die lip and traction speed.

5. Setting drum: The width of EPE pearl cotton sheet is determined by this part, so this part should provide cooling water and cooling air at the same time.

6. Traction roller: The paper stretched by the setting drum enters this part for traction. At this time, the traction speed should be balanced to ensure the quality of the plate.
