Four stages in the injection molding process May 20, 2019
Under the action of the screw thrust, the melted material has flowed through the barrel, nozzle, runner, gate, etc. at a certain rate and then injected into the cavity, and the injection pressure is gradually decreased by overcoming the flow resistance. Plastic filling process and molding quality. In addition to the injection pressure, it depends on the melt injection speed, melt and mold temperat...

Advantages of plastic gas-assisted molds Jun 03, 2019
Today we are going to discuss with the advantages of plastic gas assisted injection mold. 1. Save raw materials, increase plastic utilization rate by up to 50%, reduce molding cycle, and improve certain performance. In the case that the parts can meet the same usage requirements, the use of gas-assisted injection can greatly save plastic raw materials. 2. It can reduce the pressure of the mold by ...
Analysis of the Causes of Whitening of Injection Molding Products Jun 03, 2019
Causes whitening and halo of injection molded products. This is a defect due to contamination of impurities in gas or air. The main solution: (1) Eliminate the interference of gas, and intentionally prevent the contamination of impurities. (2) Increase the material temperature and mold temperature, and adjust the barrel temperature in stages, but prevent the temperature from being too high to deco...
