The Injection Molded Transparent Parts Are Not Transparent Enough. What Should I Do? Due to the high light transmittance of transparent plastics, the surface quality of plastic products must be strict, and there must be no markings, pores or whitening. Fog, black spots, discoloration, poor gloss and other defects, so the raw materials, equipment throughout…
DetailsThe Injection Molded Transparent Parts Are Not Transparent Enough. What Should I Do? (2) Cleaning of the barrel, screw and its accessories In order to prevent contamination of raw materials and the presence of old materials or impurities in the recesses of screws and accessories, resins with poor thermal stability are present. Therefore, the screws…

There are many types of functional engineering plastic materials and a wide range of applications. The School…
DetailsNew Progress In Engineering Plastics Application Research Engineering plastics can be divided into general engineering plastics and special engineering plastics. Polyamide (PC), polyamide (nylon), polyoxymethylene (POM), denatured polyphenylene ether (denatured PPE), polyester (PETP, PBTP), polyphenylene sulfide (PPS) are used as general engineering plastics. ), polyaryl ester, and the like. Polypropylene can also be included in…
DetailsHigh Temperature Resistant Engineering Plastic High temperature engineering plastics are engineering plastics that retain high mechanical properties under high temperature conditions. This property is generally caused by its own special structure. With the continuous development of electronic equipment, the application of high temperature engineering plastics in this field has been expanding and becoming the material…
DetailsReasons For The Formation Of Shrinkage Marks In Plastic Molds And Improvement Methods There may be one or more reasons for the formation of shrink marks, including processing methods, component geometries, material selection, and mold design. The choice of geometry and material is usually determined by the raw material supplier and is not easily changed.…
DetailsFour Factors Affecting The Fading Of Plastic Products Plastic colored products can be discolored by a variety of factors. The fading of plastic colored products is related to the light resistance of the pigment, the dye, the oxidation resistance, the heat resistance, the acid and alkali resistance, and the properties of the resin used. According…
