Magnetic flux control plays a key role in optimal coil design. We offer custom induction coil design to maximize production efficiencies to produce better parts for less cost.
As a starting point in assisting you in induction coil design, our engineering department makes a detailed analysis of the product heat treatment requirement and production environment (i.e.,workpiece material/geometry, heat treatment specification, production rate, sequence of operations, material handling equipment and available induction heating system parameters, etc.) and then considers other coil development stages including:
Heating style (limited control due to exisitng machines or bill of process)
Inductor design (coil style selection, copper cross-section, controller manufacturing & application, etc.)
Inductor engineering & fabrication
Inductor matching
Inductor set-up and tests
Final modification of inductor & process (if required)
