About Induction Heating
Can induction heating be used for heat staking?
One of the most common uses for induction heating is the heat staking of threaded metal inserts into plastic.
Most thermoplastics are too soft to sufficiently hold a thread, so brass or steel threaded inserts are added. Post-molded installation is more cost-effective than molding in place and induction is a proven way to pre-heat the inserts prior to installation. 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.
