PEI (Chinese name polyetherimide) is a thermoplastic engineering resin with an amber transparent solid appearance. It has excellent heat resistance, high strength and rigidity, as well as a wide range of chemical resistance, which can meet higher heat. Chemical and elastic demand. Its unique torsional strength among thermoplastics makes it an inexpensive alternative to small steel cutting parts. As an amorphous thermoplastic polyetherimide, PEI resin combines high performance and excellent processing characteristics, combining high heat resistance with high strength, modulus and extensive chemical resistance.

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.

Peek is a special engineering plastic with excellent properties such as high temperature resistance, self-lubricating, easy processing and high mechanical strength. It can be manufactured and processed into various mechanical parts, such as automobile gears, oil screens, gearshift starting disks; aircraft engine zero Parts, automatic washing machine runners, medical equipment parts, etc.

PEI machined parts are more cost-effective, only 1/3 of PEEK in terms of material, which can effectively reduce costs. The tooling and fixtures machined by PEI are mainly used in the 3C industry, such as mobile phone fixtures, inspection tools, tooling, etc.

Generally speaking, plastics have large crystallinity, small polarity or non-polarity, and low surface energy, which will affect the adhesion of the coating. Since plastic is a non-conductive insulator, it cannot be directly coated on the surface of the plastic according to the electroplating process regulations. Therefore, before the surface treatment, the necessary pretreatment should be carried out to improve the adhesion of the coating and provide a conductive bottom layer with good adhesion to the coating.

Semitron, as an important semiconductor material that uses synthetic mica to enhance the technical effect, can rely on various component forms to help improve the operation efficiency of the production line in specific application fields. Many users who have industrial production and construction requirements will rely on the components of this material to carry out corresponding activities to improve efficiency such as controlling electrostatic discharge after clarifying the physical properties of the material.
