Hot Runner Molding And Injection Mold

Hot runner molding effectively reduces injection mold failure rate and improves mold life

Nowadays, with the rapid development of the plastics manufacturing industry, the application of plastic products has spread all over the fields of production and life, and it has become more and more complicated and large-scale. Typical large-scale plastic parts such as TV casing, washing machine casing, large turnover box, automobile rear bumper and instrument panel, compared with ordinary plastic parts, in addition to the large size, the wall thickness is thin, the structure is complex, and the process requirements The higher characteristics, correspondingly put forward higher requirements for the design and manufacture of large injection molds, which also promoted the rapid development of large injection mold technology. It is speculated that the market demand for large injection molds will continue to grow at more than 10% in the next few years. At present, there is no uniform definition of large-scale injection molds at home and abroad. Usually, the injection mold used for injection molding machines with a clamping force greater than 6,300 kN and an injection volume greater than 3,000 cm3 is called a large injection mold, or a mass greater than 2,000 kg. The mold is called a large injection mold.
