We are expert at maintaining precise control of winding tension, winding pitch, and wire position at high winding speeds, leading to cost-effective, precision layer wound coils.
Careful design and process control of the magnet wire termination is critical to the reliability and longevity of the circuit. Guardian’s highly-skilled technicians have years of experience with termination processes, including: SPC controlled resistance welding, nozzle and dip soldering, and IDC (Insulation Displacement Connection). Thermal shock testing is available and utilized to qualify lot-to-lot production runs of the connection joint. High temperature encapsulated coil designs rated at 220°C have been qualified and approved via thermal shock testing passing 200 cycles at temperatures from -40°C to +180°C.
Guardian Electric is proud that the combination of our state-of-the-art multi-spindle winding machines and our critical technical experience has produced a “Zero Defect” quality level for electrical connections made on over a million coils delivered to our customers.
