Thermostacking Welding

Thermostacking Welding:

Thermostacking uses a system of hot air and cold stacking to form a stud that joins plastic to plastic or plastic to metal, producing a tight assembly.

Process:

A holding fixture secures the plastic part to be stacked. Plastic studs protrude through holes in the material of the connection part. A heating manifold covers the protruding plastic studs and soften the plastic with finely controlled hot air. When plastic reaches a sufficiently molten stage, the heat ceases and a cold stake head descends. The cold stake head forms the plastic stud, solifides it and creates a permanent head.

Advantages :

1. Tight mechanical connection

2. Low production cost : can simultaneous stake multiple studs. High speed production

3. No damaged to outside surface.
