① Shorten the opening stroke of the injection mold to the minimum necessary so that the parts and runners fall off; ② Exclude any factors that make ejection difficult, such as the flashing edge (Phi Feng) around the ejec...
1) The electric heating element should be evenly distributed, which is beneficial to the balanced heating of the injection mold. 2) Pay attention to insulation measures to prevent leakage and water leakage. 3) Pay attent...
1. Compression of the gas in the cavity of the injection mold will generate a large back pressure, which prevents the molten material from filling the mold normally. At the same time, the heat generated by the gas compre...
1) Variety of plastic Various plastics have their own shrinkage ranges, but even if the same plastic has different molecular weights, fillers, and proportions, the shrinkage and anisotropy are different. 2) Plastic parts...
1. The movement direction of the ejection mechanism should be accurate and reliable; there should be no jamming during the movement. It must have sufficient strength and rigidity to withstand the role of demolding resist...
Plasticizing pressure What is called plasticizing pressure? When using a screw-type injection molding machine, during the plastic melting and plasticizing process, the melt continuously moves to the front of the barrel, ...
