1. CHARACTERISTICS OF THE PART ITSELF

A. Metal Or Plastic: Induction heating works directly only with conductive materials, normally metals. Plastics and other non-conductive materials can be heated indirectly by first heating a conductive metal susceptor which transfers heat to the non-conductive material.
B. Magnetic or Non-magnetic: It is easier to heat magnetic materials.
C. Thick Or Thin: small or thin parts generally heat more quickly than large thick parts,
Research has shown a relationship between the frequency of the alternating current and the heating depth of penetration: the higher the frequency, the shallower the heating in the part.
D.Resistivity: If you use the exact same induction process to heat two same size pieces of steel and copper, steel heating is much more easier. Steel – along with carbon, tin and tungsten – has high electrical resistivity. Because these metals strongly resist the current flow, heat builds up quickly. Low resistivity metals such as copper, brass and aluminum take longer to heat. Resistivity increases with temperature, so a very hot piece of steel will be more receptive to induction heating than a cold piece.

2. INDUCTION COIL DESIGN
A well-designed inductor provides the proper heating pattern for your part and maximizes the efficiency of the induction heating power supply, while still allowing easy insertion and removal of the part.
