Step No 1: Set the dice (male part and female part) on Die Casting Machine dice holder by nut bolt and
mold setting instrument.

inside the dice with high pressure. The melted metal is poured into dice runner and gates.
The cycle time for pouring metal into dice depends on how many core are made in dice, and
thickness of button. Usually, the cycle time is 10 to 15 seconds. Each dice have multiple
core depending on Alloy Button sizes.

Step No 4: Now need to check the button quality after taking the button from separator/roller machine.
Automatic button sorting machine can be used for quality check or we can check the quality
manually.

Step No 5: Button coloring: After quality checking we need to send the button for electroplating bath as per
buyer require color.

Step No 6: After electroplating, again the quality of the alloy buttons is inspected following the standard
sample.
