Hot Gas Welded Thermostat Housing Assembly


Hot-gas welding joins both halves of this 35% GR-PPA thermostat housing assembly. The part has a small welding-flange footprint but high weld strength because there is no fiber/material degradation during the joining process. In fact, it is the only welding process that permits bridging of glass across the joint. The weld distance is held within 0.1 mm, enabling parts to package into very limited spaces with tight tolerances. Since the part is not touched during welding, there is no sticking. Versus previous aluminum solutions, the PPA assembly is 30% lighter and 40% less costly.
