Injection molding Ultem PEI 2300 parts Manufacturers

Vespel® products are made from a wide variety of materials (polyimides, thermoplastics, composites and chemically resistant polymers). These products uniquely combine physical properties and design flexibility. Parts can be supplied as custom parts, profiles, parts or assemblies. Chengtu Plastics focuses on high-precision processing of engineering plastics. Welcome to consult the professional sales team of Chengtu Plastics for any questions about DuPont Vespel.

The plastic box injection mold is composed of two sides, fixed mold and fixed mold, and the rear mold is placed on the moving template of the injection molding machine, and the fixed mold is placed on the fixed template of the injection molding machine. When injecting and molding, the back mold and the fixed mold are closed to form a pouring system and cavity, and the back mold and the fixed mold are separated when the mold is released, which is convenient for removing the plastic product.

there are more and more plastic products processing around us, plastic products processing has many advantages, such as small quality, exquisite appearance, not easy to be rotted, good impact resistance, etc., so plastic products are now very many fields and industries beloved, but also in our daily life has become a commodity that can often be seen, if you look around, there is no doubt that plastic products will appear in everyone's field of vision, it can be said that plastic has long become a raw material that is inevitable in everyone's daily life. However, many people do not know that the production of plastic products is actually asset-risky.

The burrs, 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 cracks of the insert, the pores of the ejector rod, etc. If the overflow is not solved in time, it will be further expanded, so as to form part of the embossed mold collapse, causing consistent obstruction. Cracks in inserts and top bar pores also cause the product to get stuck on the mold, affecting the release.

Nine major properties of polyimide (PI) Thermal stability: decomposition temperature from 500 ° C to 600 ° C Mechanical properties: The tensile strength is generally 100MPa

General precision injection molds have two indicators, namely equipment accuracy and mold error. The former is difficult to compare due to the difference in size and product thickness, and represents the comprehensive level of injection molding machines. Generally, the weight repetition error of ordinary injection molding machines is 1%. A good machine can reach 0.8%, less than 0.5% is a precision machine, and less than 0.3% is an ultra-precision machine. So what are the main factors affecting precision injection mold products?
