What is the questions and solutions in the production process of advanced pp hollow grid corrugated sheet making machine?

Q: Why does the surface of the board appear uneven and wavy as a whole?

Q: What is the reason for the wrinkle defects on the surface of the board?

A: Block of mold core air holes, need cleaning mold core air holes.

Q: Why Clustered wave patterns appear on the surface of the board?

A: Because the rapid discharge of materials from this area of the mold has caused material compression. Adjust the mold lip and fine tune the bolt.

Q: What should we do if the board is easy to flatten and lacks sufficient support?
