Hi everyone,the mold cooling time is the longest during injection, so the design of mold temperature system controlling is very important, we will talk about mold cooling, heating system in following 10 blog.
May 20, 2022Comparing with water-assisted injection molding technology and gas-assisted injection molding technology, the fundamental difference is the nature of the auxiliary molding media used. One is liquid an...view
April 14, 2022Gas-assisted injection molding can be divided into short shot and full shot.Short shot The short shot method is shown in picture 1, it is suitable for thick-walled plastic parts with low mold filli...view
February 11, 20221. Plastic parts design: mainly for the wall thickness of plastic products. The thicker thickness of the product, the longer the cooling time. Generally speaking, the cooling time is approximately pro...view
April 18, 20221. Firstly, considering the suitable wall thickness areas needs to be injected and hollowed out, and then decide how to connect them with the gas channel;2. The gas channel should be arranged in balan...view
December 31, 2021Plastic parts getting smaller by shrink, due to the temperature decrease during the molding process, and the shrinkage is expressed by the shrinkage rate, it is common plastic shrinkage rates are show...view
January 14, 2022Hydraulic diameter refers to 4 times the ratio of the flow cross-sectional area to the perimeter, as the wall shear stress of non-circular pipes is not even distributed along the surrounding walls, on...view
