How to Improve the Precision of Plastic Mold For the injection mold, the precision of plastic parts is grade 3 and 3a, the weight is 5g, the hardened gating system is used, and the number of cavities is 4-6; The plastic parts are of general accuracy (4-5 levels), the molding materials are locally crystalline materials, and the number of cavities can be 16-20; The weight of plastic parts is 12-16g, and the number of cavities

How to reasonably select cold runner and hot runner from an economic point of view   In the injection molding process, one of the most important functions of the mold is to transport the melt from the barrel to the mold cavity. Melt conveying management has an important influence on the final quality of parts and the final success of the production line. The precise control of resin flow, pressure and temperature is very important

Essential skills for plastic mold repair personnel As we all know, with the accumulation of mold production times on site, mold life is a process of gradual decline, from running in of new mold to normal production to the end of life. When the new mold is produced in small quantities, some problems may be exposed. Whether the mold design is reasonable and the mold processing precision meets the product requirements, the mold manufacturer will

What Is The Main Flow Of Plastic Mold? The main runner refers to the section from the contact part of the injector nozzle and the mold to the branch runner. Design considerations: (1) The end face of the sprue is usually circular. (2) In order to facilitate demoulding, the main runner is generally made with a slope. However, if the main runner passes through multiple plates at the same time, pay attention to the slope
