High Speed Injection Mould

Cooling System in Injection Molding (1) Apr 26, 2019
The design of cooling system is very important in injection moulding. This is because only when the plastic parts are cooled and solidified to a certain hardness, can the plastic parts be avoided from deformation due to external force after demoulding. Because the cooling time accounts for about 70% - 80% of the whole cycling time in moulding, a well-designed cooling system can greatly short...

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 ...
The main factors affecting mold life May 20, 2019
The main factors affecting mold life. 1. The structure of the mold -effective mold structure helps to improve the load carrying capacity of the mold and reduce the mechanical load on the mold; 2. The material of the mold - should be selected according to the size of the production batch of the product parts; The hardened mold will bring more shots and meet the high require for the mold treat...

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...

What is the most important during designing a mould ? May 27, 2019
The most important point is structure , If the structure can be simplified as much as possible, but the quality of the mold must be guaranteed, the company will earn the maximum profit from it . When we received a product , the first question is find out the biggest parting surface , Roughly determine the cavity and the core , then , To Analyze the construction of cavity and core , insert , ...
