PC plastic injection molding process has a very thin bubble of gas belonging vacuum bubbles. In general, if you have found bubbles in the mold instant belongs gas interference. It is due to the formation of vacuum bubbles filled into plastic insufficient or lower pressure. In the rapid cooling effect of the mold, and the cavity then angle of the melt pull injection molding, resulting in the loss of volume results. (1) Set the gate in the thick part of the workpiece, improving the nozzle, runner and gate flow conditions injection molding manufacturers, to reduce the pressure of consumption. (2) improve mold venting condition. (3) increase the injection energy: pressure, speed, time and quantity, and increase the back pressure, so filling fullness. (4) increase the smooth flow of the material temperature. Reduce material temperature to reduce shrinkage, an appropriate increase in mold temperature, especially in parts of the partial vacuum bubbles forming mold temperature. After years of wind and rain appliances injection molding, after all the staff of struggle, hard work, enterprising, innovation and development, now has a professional technology, production, sales and management team, the company has advanced injection molding, blow molding production lines, from raw materials to Finished with a sound detection test system, with the ability to mass production.
