The English name of PEI Chinese polyetherimide board is Polyetherimide, PEI belongs to amorphous plastics. It is an amorphous high-performance polymer, which is extruded from engineering plastics made of amorphous PEI (polyetherimide) at high temperature by an extruder. At present, the commonly used PEI board is the raw material (Ultem) of GE in the United States. In 1972, GE of the United States began to research and develop PEI.

We should all be familiar with rubber and plastic products, but most people still don't know some professional knowledge. Let's take a look at the hazards of rubber and plastic products, so that everyone can use them better.

During the continuous operation of the mold, it is easy to cause problems such as wear of parts, deterioration of lubricants, water leakage, and crushing of plastic materials during the movement process, so mold maintenance is required.

Shawl, also known as flying edge, overflow, overflow, etc., mostly occurs in the parting position of the mold, such as: the parting surface of the mold, the sliding part of the slider, the crack of the insert, the pores of the top rod, etc. If the spill is not solved in time, it will further expand, resulting in partial collapse of the imprint mold, resulting in a permanent obstruction. Insert cracks and the cape of the pores of the ejector bar can also cause the product to get stuck on the mold, affecting the mold release.
