Polyetheretherketone sleeve Manufacturers

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.

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.

Nylon products have many advantages, such as good performance in impact resistance, wear resistance and fatigue resistance. Therefore, nylon gears are widely recognized and welcomed by consumers in the market. It should be noted that nylon products have been used for nearly 30 years in helical gears, worm gears, spur gears and helical gears.

Confirm the cooling water path, the depth of screwing the screw into the plate is 1.5-1.8 times the diameter of the screw. If the screwing is insufficient, it is easy to slip the teeth, and there is a danger of mold falling. Check whether the staff, materials, tools, documents, equipment auxiliary equipment, etc. required for production are in good condition.

What factors affect the chemical resistance of PEEK rods: Important influencing factors include: continuous working temperature, mechanical load, climate influence, fire performance requirements and electrical conductivity.

The characteristics of plastic injection molding are determined by the characteristics of the raw material, and there are two main points: one is the filling activity of the plastic melt during injection, and the other is the shrinkage position of the plastic in the mold cavity when it is cooled and cured. These two points determine the difference of the injection mold and the difficulty of the injection mold design. When designing injection molds, it is necessary to inquire about the characteristics of the processed plastic raw materials, so that the designed injection mold is more reasonable, and the characteristics of plastics are usefully exercised in the design process. Therefore, the questions that need to be considered in the injection mold design process are as follows.
