Question: Why does the mold head of the ABA film blowing machine always appear thick in the middle and thin on both sides?
Resolvent:
1.The mold head of the film blowing machine has accumulated carbon and needs to be disassembled and cleaned.
2.The mold core has been damaged by a hard object or is deformed.
3.The heating ring of the mold head is damaged, causing some areas to be heated while others remain unheated, resulting in uneven material discharge.
4.Clean the air tray and replace it with a brand new air duct to ensure even air output.
5.Replace the mold.
