Magneforce will build induction heating coils of all types for our own equipment or that of other manufacturers.  We will provide engineering drawings based on our own design or your sketches or sample coils and promptly quote price and delivery.  All induction heating coils are inspected for correct terminal type, insulation method, and dimensions and are flow checked and leak tested. Coils are identified by individual drawing numbers which are retained for future orders.

Induction Heating Coils can be multiturn stand-alone assemblies or simpler, shaped windings used in combination with an output transformer which steps up the current and steps down voltage.  With this arrangement, many different induction heating jobs require only a coil change. These coils are almost always water cooled. Multi-turn coil assemblies which do not require an output transformer can be constructed as water cooled or air cooled assemblies depending on the use.

Coils designs are usually specific for a job.  Heating coils can be solenoid types which surround or fit inside the part (most often used), U coils which are open on one side, split coils, and flat wound which heat from a side.  By adjusting turn size and position or combining coil types in a single coil, a required heat pattern can be arrived at.  Heating coils can also be made to heat a number of positions simultaneously. Coils can be bare copper but are most often coated with an insulation material which matches the demands of the heating process. Coatings include powder coats,  epoxies, varnishes, ceramic (alumina, zirconia, or chromium oxide) or refractory  lined.  Induction heating coils can also be machined from solid copper, mechanically supported, or fully encapsulated.
