Also apply the parting powder (baby powder) onto the sand and the pattern. ( for realising the pattern from the sand and prevent lateral two layers of sand from sticking.

place a runner (a hollow tube) as the sprue,and another channel as the riser on the opposite part.

Ram the sand down again with the ramming tool .

remove the sprue and the riser.

take out the pattern from sand, cut gates
