Hi! I’m about to build my first injection machine and some a question about the production pop up to my mind.

Once plastic is injected to the mould, how much time is the recommended to wait before remove it and let it cool down aside?

Also how much time (approximate) do I have to wait before remove the product from the mould?

I know it may vary on the size of the mould and quantity of plastic, but let’s say is an hexagonal coaster mould (HDPE).

Hope you can help me.
Thanks!!
