One of the most common uses for induction heating is the heat staking of threaded metal inserts into plastic. Most thermo-plastics are too soft to sufficiently hold a thread, so brass or steel threaded inserts are added.
For heat staking, the insert is preheated with induction and then pressed into a hole in the plastic part. This is accomplished by positioning the induction coil over the hole and then holding the insert in the coil for a short period of time.
Injection-molded plastic parts are used increasingly in a variety of industries including automotive, office furniture, cutlery, gardening equipment and more, because of their strength and lighter weight when compared to metal.
