Our newly updated design guide, titled the Heat Staking Design Guide: Inserting Metal into Plastic with Induction by Dr. Girish Dahake, is now available for download. Heat staking of threaded metal inserts into plastic (also known as metal-to-plastic insertion) is a common induction heating application, and this design guide will help you get started. With 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. When the correct temperature is achieved, the insert is pressed into the plastic.

Induction Heat Staking Magnetic Steel Inserts for Injection Molding

May 25, 2018 3:39:50 PM / by Brett Daly posted in Metal-to-Plastic, Application Notes, heat staking, heat staking with induction


A supplier to an engine manufacturer needed to heat magnetic steel inserts for a metal-to-plastic insertion (also known as heat staking) application. The parts needed to heat to 500 °F (260 °C) within five seconds prior to being placed into an injection mold. Due to it taking the robot a few seconds to place the parts in the mold, it was also important that it maintain the temperature for a few seconds after heating concluded.

8 Keys to Quality Induction Heat Staking (Metal to Plastic Insertion)

Oct 27, 2015 7:40:00 AM / by Justyna Bakker posted in Metal-to-Plastic, heat staking with induction

Metal to plastic insertion -- or heat staking -- is a popular induction heating application at Ambrell's worldwide application laboratories. Dr. Girish Dahake, Senior Vice President of Global Applications, and his team have seen this application with great frequency. He published an article in Industrial Heating on the topic, and here are eight critical parameters that he highlighted for a consistent induction insertion process:
