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 2โ (50.8mm) diameter, 2โย (50.8mm) tall, copper powder
Temperature 1600 ยบF (871 ยบC)
Frequency 54 kHz
Equipment โข DW-HF-45kW induction heating system, equipped with aย remote workhead containing eight 1.0 ฮผF capacitors for aย total of 8.0 ฮผF.
โข An induction heating coil designed and developedย specifically for this application.
Process A four-turn helical coil is used to heat the assembly for fiveย minutes. This provides slow, even heat for good penetrationย through the shell into the powder.
Results/Benefits Induction heating provides:
โข Even heat through the shell to sinter the powder.
โข A method that is easily integrated into an automatedย production line. The design may be adapted to
accommodate the indexed heating of several assemblies atย the same time.
โข Hand- free operation that involves no operator skill forย manufacturing.
