Heat Shrink Tube Insertion and Baking Machines
Inserting the sleeve and shrinking it are two operations, and between them the sleeve sits loose on the splice — where it can be displaced, dropped, or fitted on the wrong side of a connector. Machines on this page insert and bake in one cycle so the sleeve is never a loose part in the process. This matters most on short splices where the sleeve has little to grip before shrinking. The specification inputs are the tube inner diameter and shrink ratio, the sleeve length, and the splice geometry. Insulation that sits inside the shrinking zone has to be checked against the dwell temperature, because overheating it is a defect that appears weeks after shipment, not during assembly.
Built and Tested in Our Workshop
Every machine is assembled in our Dongguan workshop and run in before shipment. QC sequence: Raw material check → Machining → Assembly → 100% run-in test → Shipment video. A test video on your own material is available on request.
