The design difficulties of PEI injection mold mainly focus on the molding temperature, molding pressure, mold structure, cooling system and precision requirements. PEI injection mold is a kind of polymer material, with excellent corrosion resistance, wear resistance and self-lubrication, so it is widely used in electronics, automotive, aerospace and other fields.
The design difficulties of PEI injection mold are as follows:
1. The molding temperature of PEI is relatively high, so it is necessary to select high temperature resistant materials and reasonable heating system to ensure uniform and stable mold temperature. In addition, in order to reduce the molding pressure, the mold structure of multi-gate and multi-cavity can be used to improve production efficiency.
2.PEI has a long cooling time, so it is necessary to design a reasonable cooling system to ensure uniform cooling of products. Exhaust system is also one of the difficulties in the design of PEI injection mold, the need to design a reasonable exhaust system to avoid bubbles.
3.PEI products require higher precision, need to design a reasonable mold structure, in order to improve the accuracy of products and surface quality. In the manufacturing process, we can use precision machining, CNC machining and other technologies to improve the manufacturing accuracy of the mold.
4. According to the characteristics of PEI, some special techniques can also be used to improve the quality and performance of products. For example, pretreatment processes can be used before injection molding to improve the mechanical properties and dimensional stability of the product. In addition, a hot runner system can be used to avoid forming defects caused by local temperature changes.
PEI injection moulds are widely used in electronics, automotive and aerospace fields. In the electronic field, PEI injection mold is mainly used to manufacture a variety of circuit boards, connectors, etc.; In the automotive field, PEI injection mold is mainly used to manufacture automotive engine parts, oil tank caps; In the field of aerospace, PEI injection mold is mainly used to manufacture various seals, bearings and so on.
At present, PEI injection mould market develops rapidly, its application scope expands unceasingly. PEI injection mold has the advantages of wear resistance, corrosion resistance and self lubrication, which can effectively improve the service life and performance of products. In addition, with the rapid development of automotive, electronics and other industries, the demand for PEI injection mold is also increasing. Therefore, PEI injection mold has a great advantage in the market.
