two phase thermoforming

two phase thermoforming for deform plastic rivet domes in two phases. Phse one, geat up with hot air, phase two, deform with a cold forming stamp.

Particle free welding process
•
Radiant heat
•
No pollution on the heating element
•
Welding of nearly all kinds thermoplastic materials
•
Gas temperature possible up to 800 C
•
Lower mechanical stress on the components as eg ultrasonic riveting
•
N o material adhesions on the tools also for materials with low viscosity
m elt by contactless plasticization and cold " forming punch
•
High welding seam strength
•
Possibility of simultaneously welding
•
