How does the purity of steel affect the mold performance? Feb 22, 2019
The purity of steel mainly refers to the quantity, type, morphology, size and distribution of non-metallic inclusions in steel. Non-metallic inclusions usually refer to harmful impurities such as oxygen, sulfur, phosphorus, hydrogen and nitrogen remaining in mold steel. The smaller the percentage of these impurities in a unit volume, the higher purity of mold steel. The purity of mold steel ...

What is Ejector Marks? Apr 12, 2019
Ejector mark is the phenomenon of stress whitening and stress elevation where appears on the opposite side of the nozzle facing the product, or where the ejector rod is located on the ejecting side of the tool. Why will it cause the ejector marks? The physical reason is when the demoulding force is too high or the surface of the ejector rod is relatively small, the surface pressure will be very hi...

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...
