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...

Welding Line is refers to the slim line disappear in which the plastic raw material melting and collecting. Why it happens? 1. Insufficient liquidity of melting raw materials 2. Have air or volatile component 3. Release agent or colorant 4. Defect of mold design How to improve? 1. Change raw material to better liquidlity 2. Check and improve the air venting, decrease the injection speed 3. Use les...

How many you know about the ultrasonic plastic welding? Plastic welding refers to the method of heating the contact surface of two plastic parts to melt at the same time, so that they are combined into a whole connection method, only applicable to the thermoplastic joint welding, we can use electrode or not use electrode. When using the welding rod, the end face of the welding end shall be made in...
