と、溶湯と反応してガスが発生しやすくなる。Further, the powder having lubricity is for improving the lubricity between the inner peripheral surface of the injection sleeve and the outer peripheral surface of the plunger tip, and the powder having self-lubricating property in the powder state, Specifically, stearic acid, stearic acid salts of stearic acid with sodium, magnesium, zinc, calcium or the like, or a mixture thereof can be used. And as for the usage ratio, the total amount is 16 wt
% Or less is preferable. If it is added in an amount of 16 wt% or more, gas is likely to be generated by reacting with the molten metal.
