Magne AC3 Air Cooled Heating System

The Magneforce MagneAC3 is a custom high frequency electromagnetic heating system that is air cooled, easy to use and does not require water cooling.  It is specifically designed for the flameless, non-contact, reliable heating of metal threaded inserts for pressing into molded and printed plastic parts, particularly when the possible problems associated with water cooling are not acceptable. It consists of the air cooled induction heater in combination with a compact air cooled heating head.  The heating head is small, lightweight and can be mounted to most any processing fixture.

The heater operates on a standard 115V outlet and produces up to 1200 watts for fast heating.  It incorporates a unique power connector that enables the heating head to be easily plugged in or removed in a few seconds.  A temperature sensor molded into the head prevents any possibility of overheating during operation.  A range of head sizes enables heating of a wide variety of brass and steel inserts, with typical heat times of a few seconds to 500F for steel inserts.  Custom designed heads are available  for specialty applications, such as catheter tipping  epoxy curing and coax cable soldering.

Magne AC3 Power Supply

The Magne Power Supply is a solid state high frequency electromagnetic heater.  It is air cooled, small and lightweight.  Standard features include a rear mounted control panel with on/off circuit breaker, LED status lights for POWER ON, FAULT, HEATING and TEMP.  Also included is a precision 2 digit pushbutton potentiometer for rapid, accurate power output setting and a 4 pin control jack that enables remote on/off control and provides a 0-5Vdc signal proportional to operating power to enable monitoring the heating operation using the included cable.

Other features include power tracking circuitry that delivers constant power with varying input voltage, a fast trip semiconductor fuse to protect internal components and temperature control circuitry to monitor the temperature of the heating head. 

The power supply also incorporates a unique, plug in power connector mounted on the front of the unit. This connector utilizes high amperage hyperbolic connectors with integral locking feature that allows connection or replacement of the heating head in a matter of seconds.  It includes additional contacts to prevent heating unless the head is plugged in and also to connect to the temperature sensor inside of the heating head.

Air Input

The Magne heating head assembly concentrates the electromagnetic field produced by the power supply into a small, focused area for heating inserts or many other metal parts.  It consists of the heating head with .50", .62" or .75" central hole for the part, a 36" long power lead with nylon convoluted tubing protective covering and a custom quick connect power plug for connection to the power supply. The complete assembly weighs less than a pound.

The head is constructed of high temperature fine gauge litz wire encapsulated with thermally conductive flame retardant epoxy enclosed in a printed nylon housing. Due to the high amperage that needs to be conducted in order to generate the magnetic field required for heating, the head will heat up with use. For low duty cycle applications where there is a significant lag time between parts due to fixturing and other requirements, the head can be operated as is without additional cooling.   For higher duty cycle applications, an auxiliary air supply of 20-30 psi can be connected to the head using the hose barb.  This will circulate air through the interior of the head and allow operation up to a duty cycle of 50% e.g. 3s on/3s off, which is satisfactory for most applications.

The head includes a temperature sensor imbedded into the encapsulated litz wire core.  If the head gets too hot, the TEMP light on the rear of the unit will turn on, an alarm will sound and heating will be disabled.  The head connector also includes an interlock where heating cannot be activated unless it is properly plugged into the power supply receptacle.
