Shrinking Tubing Heating Oven Shrinking Tubing Heating Oven

WL6617-1 is a heat shrinkable tube heating device designed for mass production and can work continuously for 24 hours. The heating block of the machine is uniform and does not hurt the wire. It can realize single-end heating and intermediate heating, and adjust the heating range according to the length of the heat-shrinkable tube. The speed of the conveyor can be kept uniform by manually adjusting the speed.

The vertical distance and parallel direction of the heating port to the conveyor belt are adjustable, which is suitable for heat shrinkable tube heating of different size parts. It is suitable for users who have high precision requirements for wire harness heating, and is also suitable for heating high temperature resistant Teflon heat shrinkable tubes.
