1. The two-color injection molding machine consists of two sets of plasticizing injection devices with the same structure and specifications. According to the production method, the nozzle needs to have a special structu...
1) The cross-sectional area of the injection mold is large, and the hardenability of the selected steel is poor; 2) The carbonization material contained in the selected injection mold steel is severe; 3) The forging proc...
1. Gas generated from the decomposition of plastic melt Some raw materials produce volatile gases when heated, and many raw materials also generate volatile gases when they are overheated. These gases are corrosive and t...
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...
