Why Magneforce Induction Insert Heating
Our Magne AC3 induction heaters do not require any water cooling, eliminating possible problems of water leakage and the need for coolant recirculators. Heating times are as low as 2 seconds and duty cycle up to 50%.
Plug In Heating Heads
Heating heads for the Magne AC3 heaters plug into the power supply and can be changed in seconds. The heads are small, lightweight and easily fixtured. Up to 2 inserts can be heated from 1.75" to 24"between inserts.

4 Threaded Inserts are heated to 550F in a few seconds. Temperature indicator coating is used to help determine the correct heating time
Threaded inserts are widely used for pressing or heat staking into injection molded and 3D printed plastic parts to provide high strength screw threads. One of the best methods for installing threaded metal inserts is to preheat them so that when they are pressed into the part the plastic is melted and flows around knurls built into the insert. This firmly holds the insert in place with high torque handling capability. Induction heating is often used as the method of choice for heating inserts prior to presssing into the part.

ISM33 Induction Insertion Press
Our NEW ISM33 Induction Insertion Press incorporates a touchscreen controlled air cooled induction heater with a closed loop linear actuator and patent pending insert
pickup system. It is designed for applications where repetitive, verifiable high quality insert placement is required. All process parameters including heating time and power, insertion speed and location and insert temperature are easily set using the 7" touchscreen. Optional insert delivery turntable holds up to 50 inserts.

Water Cooled Induction Heaters For Insert Pressing
Magneforce Heat Station and Magne AC3 heaters are often used as a primary component of custom built manual, semi-automatic and automatic assembly equipment for industrial processes. They provide rapid, non-contact heating of brass and steel threaded inserts. Heating is reliable and consistent from part to part, insuring quality, repeatable insertion. There is no hot tip or horn to wear out. Only the insert heats up, the heating element stays cool. The heaters are easily controlled by your PLC and provide a DC output signal to verify proper heating for every cycle.
Insert Heating Heads Custom Made For Your Process
We design & manufacture custom heating heads to fit your part and process. The heating elements are typically enclosed in phenolic housings to prevent mechanical damage and to easily mount in position in your setup.
Magneforce Heat Station 2500R2 & 5000R2 induction heaters can heat up to 6 inserts in almost any configuration. Duty Cycle is greater 80% and heating times to 600F as low as 1 second. Custom heating heads can be located up to 6' away from the induction power supply.

Fast, Quiet, Non Contact Repeatable Heating
Heat Inserts as quickly as 1 second each. Precise heat control insures consistent heating cycle to cycle. The heating head does not contact the insert. There is no resistance electrode or horn to wear out or require adjustment. Heating is quiet. There is no loud ultrasonic noise to put up with.

Air Cooled and Water Cooled Induction Insert Heaters
Magneforce manufactures both water cooled and air cooled induction heaters. Our Heat Station 2500R & 5000R water cooled heaters provide fast heating times and can be set up to evenly heat as many as 6 inserts at a time. Our Magne AC3 air cooled heater is easy to set up and use and can heat up 2 inserts located up to 24" apart.

Evenly heat 1 to 6 inserts at once. The heating heads are made to match the hole layout in your part. Many heads include a protective G-11 phenolic housing to protect the induction coil from damage and to provide precise locating holes for mounting in your machine
2 G-11 phenolic encapsulated heating heads with locating holes. The enclosure is shaped to fit the part. The heads are mirror images to heat inserts at opposite ends of the part.
Control With Your PLC
Heating on/off, time & power level can be controlled from your PLC. A DC voltage signal from the induction heater to to PLC can be used to verify heating.
Made In The USA
All Magneforce induction heating systems for insert heating are manufactured at our facility in Warren, Ohio.
