Claim 10:
11. A die casting process using the die casting machine according to claim 1, the die casting process comprising:
a gap forming step of making the mating surfaces face each other across the gap to make the cavity and the external part of the pair of dies communicate across the gap,
a molten metal feeding step of feeding the molten metal into the sleeve when the gap is being maintained,
an injection step of starting the forward movement of the plunger at the time when the gap is maintained and there is the molten metal in the sleeve, and
a clamping step of making the mating surfaces abut against each other to eliminate the gap after the start of the forward movement of the plunger and before the arrival of the molten metal at the molten metal surface height at which the molten metal flows into the gap.
