The thickness of the board foam is inconsistent

The thickness of the board foam is inconsistent

In the production process of XPS, EPS, and PET board foam, uneven thickness of the foam boards is a common problem we encounter. For this, we have provided corresponding solutions for different causes.

1. Inconsistent spacing between upper and lower molds: Adjust the screws of the upper and lower mold mouths. For thicker plates, tighten the screws corresponding to the mold position appropriately. For thinner plates, loosen the screws corresponding to the mold position appropriately.

2. For the issue of molten temperature: The higher the temperature, the more severe the concave core of the sheet becomes. Temperature can be decreased in batches for the No. 2 main machine by 3°C to 5°C.

3. Adjust the temperature difference between the two sides of the mold.
