The advantages for Hot Runner Mold Apr 22, 2019
The hot runner mold refers to a mold that uses a heating device to keep the melt in the flow passage from solidifying at all times. Because it is shorter than the traditional mold shot cycle and saves raw materials, hot runner molds are widely used in various industrialized countries and regions in the world today. Shorten cycle The molding cycle is shortened. Because there is no restriction on th...

The program control of injection speed Apr 26, 2019
The program control of the injection speed is to divide the injection stroke of the screw into 3 to 4 stages, and each of the stages uses an appropriate injection speed. For example, when the molten plastic just starts to pass through the gate, the injection speed is slowed down, and during the filling process, high-speed injection is used, and the speed is slowed down at the end of filling. With ...
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...

How to choose the mold steel for mirror polishing? May 20, 2019
To make high quality mirror polishing on mold (cavity and core inserts, same as below), the requirement of mold surface polishing of mold is high, because this is the most important loop of mold manufacturing. The surface with roughness and corrugated grain is an abnormal phenomena in mirror polishing of molds. Generally, it is the the mold steel material, the polishing method, or the inject...

Purpose of mold polishing May 24, 2019
Polishing is an important process in the plastic mold making process. With the increasing application of plastic products, the appearance quality of plastic products is getting higher and higher, so the surface polishing quality of plastic mold cavities should be improved accordingly. Molds with specular and high-gloss surfaces have higher requirements on the surface roughness of the mold and ther...

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 ...
