ABSTRACT:
Controlled infrared heat is used to bond plastic parts (50) together. A fixture (14) includes platens (20, 26) to hold the parts (50) in spaced and aligned relationship during the heating phase of the bonding process, and movable supports to press the platens (20, 26) together during the bond forming phase of the bonding process. A screw transfer system (28) is provided to locate infrared heat sources (42) between the parts (50). An operator station (44), having a controller (48), maintains a minimum voltage (V1) in the heat sources (42) until the heat sources (42) are located, and then, increases the voltage to a second level (V2), to correspondingly increase the heat output of heat sources (42), for a first time period. Operator station (44) then increases the voltage to a third level (V3) for a corresponding time period before reducing the voltage, removing the heat sources (42) and pressing parts (50) together to thereby form a bond.
