The reason for pressing is to increase the contact area between the lead alloy and the concave portion 9 of the mold 6, facilitate heat conduction during induction heating described later, and reduce the temperature variation of the molten metal 7.
The mold 6 having the lead alloy block in the recess 9 is induction-heated using an induction furnace (frequency 30 kHz, output 30 kW, heating time 10 seconds) manufactured by Fuji Denki Koki Co., Ltd. The lead alloy placed in the depression 9 is melted to produce a molten metal 7 at 450 ± 10 ° C. The reason why the frequency is set to 30 kHz is that it is an area where the worker does not feel noise. By using this method, the temperatures of the mold 6 and the molten metal 7 can be made substantially constant.
