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...

Welding Technology of Plastic Mold Jan 16, 2020
The most commonly used welding methods for plastic mold engineering parts are: high temperature tool welding, rotary welding, vibration welding, ultrasonic welding, and other methods: high frequency welding, induction welding, hot gas welding, laser welding, etc. In order to obtain high-quality and reproducible welding quality, a suitable welding method needs to be selected to optimize the welding...
Defects analysis of injection molded products - Bubbles Jan 17, 2020
Bubbles are the phenomenon of small volume or series of pores formed inside the product. A large amount of gas is mixed into the melt and is formed by cooling the melt. 1. Venting system is bad or blocked 2. The cooling system is not setting properly, which makes the material cooling uneven or insufficient. 3. The injection speed is too fast 4. The material temperature is too high, which will caus...
