Induction Heating Sintering Copper Powder

Induction Heating Sintering Copper Powder With High Frequency Induction Sintering Heater Objective Sintering copper powder to a stainless steel shaft Material Steel shaft & shell assembly, approx 2” (50.8mm) diameter, 2” (50.8mm) tall, copper powder Temperature 1600 ºF (871 ºC) Frequency 54 kHz Equipment • DW-HF-45kW induction heating system, equipped with a remote workhead containing eight 1.0 μF capacitors for a total of 8.0 μF. • An induction heating coil designed and developed specifically for this application. Process A four-turn helical coil is used to heat the assembly for five minutes. This provides slow, even heat for good penetration through the shell into the powder. Results/Benefits Induction heating provides: • Even heat through the shell to sinter the powder. • A method that is easily integrated into an automated production line. The design may be adapted to accommodate the indexed heating of several assemblies at the same time. • Hand- free operation that involves no operator skill for manufacturing.
