23 HOT JAW BONDERDownload .pdf

The Hot Jaw Bonder is a machine designed to bond plastic tubes. The bonding energy is transferred through electrically heated clamps and the inner-tube diameter is fixed by a mandrel. The necessary force to achieve a tight fit between the two tubes is applied through the use of a shrink tube during the welding process. Relevant process parameters include: temperature, time, mandrel diameter and size of clamp.

The correct position is given by an adjustable stopper and the welding process is initiated by applying pressure to the foot switch pedal. Up to three products can be processed simultaneously.
