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

Insert Molding Development Considerations Dec 27, 2019
INSERT MOLDING is a type of mold in plastic mold, commonly known as insert mold. There are some differences between this type of mold and ordinary plastic molds in the selection of plastic materials, mold design and development testing, which are described in detail below. Inserts in INSERT MOLDING molds are usually stamping parts or threaded inserts. Before injection mold clamping, they must main...

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 ...

Discussion for transparent plastic raw materials Jan 16, 2020
The types of transparent plastic raw materials usually are acrylic or PMMA, PC, PET, transparent nylon, etc. Among them, we have been exposed to three kinds of plastics: PMMA, PC and AS. Transparent materials usually used in six major application areas: (1) Daily commotidities: Transparent film: PE, PP, PS, PVC, PET, etc. for packaging, agricultural PE, PVC, PET, etc. Transparent sheet: PP, PVC, P...

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...
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. ...
