Types of fusion 250 plastic pipe welder

1. Ultrasonic welding

Ultrasonic can be used not only to weld hard thermoplastics, but also to process fabrics and films. The welding head transfers the received vibration energy to the joint of the workpiece to be welded, where the vibration energy is converted into heat energy by friction, and the plastic is melted. Ultrasonic can be used not only to weld hard thermoplastics, but also to process fabrics and films. 

2. Hot gas plastic pipe welder

Hot gas welding is heated to the desired temperature by compressed air or inert gas (usually nitrogen) through the heater in the welding torch and sprayed on the plastic surface and strips, so that the two are melted and combined under low pressure. This method is often used for the China butt welding machine of PVC, polyethylene, polypropylene and other plastics. 

3. Vibration but welding machine

Vibration welding is suitable for almost all thermoplastic welding, medium or large parts with allowable unconstrained motion welds in the reciprocating direction. The material factor of vibration welding is similar to that of ultrasonic welding: amorphous materials are more suitable for vibration welding than semi-crystalline polymers. Ring vibration welding can connect parts whose size of the welding zone is approximately equal to the distance from the welding zone to the axis of rotation.
