Plastic injection mould in the precision requirement is very strict, and the life of the plastic injection mould calculation is also very standard, divided into normal wear scrapping life and premature failure life, abnormal scrap plastic extrusion die to record the number of production profile, calculated weight are available, and also the number of root casting rods by calculation.
Changshu well below da plastic products factory is a quick rundown of restricting plastic extrusion die quality improvement of the three elements.
the first element is the high temperature of plastic injection mould. High temperature and high pressure job would make plastic extrusion die load cycles shorter, which requires the plastic injection mould with high temperature, high heat stability, heat resistance and strong toughness.
plastic extrusion die first period of development, the domestic commonly used 3 cr2w8v steel mould, but this kind of steel quickly eliminated by the market, because of its low toughness, thermal stability is bad, can't meet the production needs, in recent years was replaced by the high quality mould 4 cr5mosiv1 steel structure, its service life is three to five times of the former, the high temperature are more excellent heat resistance and toughness.
the second element is the design of plastic injection mould parameters. The production of plastic injection mould machine is completely according to the parameters of the production drawings, design and the processing environment and process of mold level the demand is higher, do not appear improper design parameters, material is not required. Correctly calculate the reasonable and accurate design parameters, and to the high standard requirement of the manufacturing environment is very important.
the third element is the mechanical properties of the plastic injection mould. Only unilaterally pay attention to product eligibility is not comprehensive, and the pursuit of the mechanical properties of the plastic injection mould, avoid the calculation error caused by the excessive and inner surface of uneven edges and corners, as a result of plastic extrusion die life shortened or direct damage, emphatically pay attention to the stress of the plastic injection mould machine.
considering each processing profiles and comprehensive characteristic of plastic extrusion die design is improving the quality of plastic injection mould and the service life of the critical processing elements.
