How much do you close your sprue plate while casting? I was casting with my 6 cavity 38-148 WC today and noticed that I don't force my sprue plate completely. While it's possible when the mold is being stored, the sprue plate needs to be forced closed and I'm thinking that this must be from metal expansion. My concern is forcing the sprue plate closed and distorting the mold so the two halves don't close. As long as the hole lines up with the cavity, I am fine. Is what I am doing correct? I'm just wondering.
