ABSTRACT:
A hand-operated thermal press for installing metal inserts in a workpiece of a thermoplastics material comprises a frame (12) including an upright post (16) on which is slidably mounted a support bracket (24) carrying an insert driver (18). Movement of the bracket (24) along the post (16) is limited by adjustable clamps (20, 22) and the bracket (24) is biassed into a starting position by a coil spring (28). A hand-operable mechanism (34) is provided for moving the insert driver (18) along the post (16). The insert driver (18) incorporates a heating unit movable relatively to the insert driver (18) against a biassing spring (100). The heating unit includes a core (70) heated by the unit and which supports a bit (92) adapted to receive the metal insert to be installed. The clamps (20, 22) are adjusted to provide a required movement of the insert driver and the spring bias (100) ensures a consistent driving force for installing the insert.
