What is the delamination of the plastic product? Oct 23, 2019
It means that products delamination like mica sheet, because different material is mixed, especially for different Shrinkage material. There are a few reasons caused this problem: 1. The melt temperature is too low, material couldn't conbine well. It may caused products delamination under ejected acting force. 2. The back presure is too low. 3. The material consistency is not so good. 4. Mat...

Short shot Nov 20, 2019
We are going to talk about one of the most common problem during mould trial--short shot. The factor are as below: 1. It means that the cavity is not completely filled, caused the plastic parts incomplete; 2. The mold venting is not good; 3. The section of gate and runner is too small and long, The melt pressure loses too much during the flow; 4. The thin wall is not thick enough; 5. There is no c...

The process for injection molding Dec 13, 2019
The Last Shot Stage → Closed mold → Filling → Holding Pressure →Plastic Melting → Part Cooling → Mold Opening → Demolding → The Next Shot Stage During the filling and holding stage, the cavity pressure rises with time. After filling the cavity, the pressure will remain in a relatively static state to supplement the insufficient amount of plastic due to shrinkage. This pressure can prevent the resu...
