                                       Some basic points of plastic injection molds, with the rapid development of modern industry, the extensive use of plastic products in agriculture, daily life, electronic technology, and other fields, the quality requirements of plastic products are also getting higher and higher, and daily life supplies are also receiving special attention. Plastic products, mold design, 2, production and quality control, 3, advanced mold manufacturing equipment and reasonable processing, 4, molding mold quality materials and advanced equipment are important conditions affecting the formation of plastic parts.

In the injection molding process, the mold is closed while withstanding the injection pressure. The plastic mold is cooled and frozen, and the injection device currently used has two designs: a screw pre-plasticizer or a two-stage device, and a reciprocating screw. The screw pre-plasticizer uses a pre-plasticized screw (first stage) to inject molten plastic into the injection rod (second stage) injection molding process, including plastic injection molding, such as compression molding, blow molding, and extrusion. The method applies to all parts of thermoplastics and thermosets.

In the injection mold industry, the technical requirements are more and more advanced, the mold cavity and shape are more and more complex, the precision of precision molds is getting higher and higher, and the demand for production cycle is getting shorter and shorter. The plastic injection molding process requires precise control of melt temperature, melt viscosity, injection speed, subsequent pressure of injection, pressure from the speed switching point, and cycle time.

Studies have found that different polymers have different characteristics and different limits. The plastic injection molding process involves several factors, some of which are very important. They play a decisive role in the control of injection molding processing. Such as freezing time and injection time, maximum injection speed, maximum injection pressure, injection power, plasticization rate and other applications of injection molding technology, process technology directly affects product production efficiency, quality and cost.
