The reason of air traps of a molding product Dec 23, 2019
The reason of air traps of a molding product: 1.Poor venting of the mold 2.The plastic raw material break down 3.Mold design is unreasonable(such as sprue is too small) 4.Injection speed is too fast How to improve air traps: 1.Improve the mold venting 2.Lower down the hopper temperature 3.Improve mold design (like enlarge the sprue) 4.Lower down the injection speed

What is Mold Texture Technology? Jan 16, 2020
Texture is a very common process when we build a mould. What is mold texture processing? we are going to talk about this today. Texture is a process that etching mould for reaching the surface requirement(like fog surface, pattern,and so on). If you only need small natural patterns, such as fog surface, then only need electronic discharging. Texture can improve the product a little bit stick mold ...

What are the procedures for texture? Jan 16, 2020
Before, We have talked about the mould texture. There are 7 procedures for mould texture as below: 1.Cleaning the cavity surface 2.Covering the cavity surface which no need to be texture,or painting antiseptic paint on it 3.Drying the antiseptic paint 4.Using degrease cotton to clear the cavity surface which need to be texture, make sure that there's no any impurities and filth to effect texture. ...

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...
