Hi everybody i'm very happy i have found this interesting website ! great stuff i hope somebody could give me some info about my problem. I have a new cnc machine to make moulds For testing i have made an injection mould in composite material, its rock hard and easy cutting. The surface is smooth and glossy like aluminum. I use this becaus i have it for free... But i have a problem. My shad baits have a "inside bumb" (on one side) its like they are collapsed a little bit i think a kind of cooling reaction in the mould. So i tried several things, i have enough air vents but i can't get it solved. The mould contains 3 shad baits, the head of the bait is 3/4 " wide the injection chanel is 1/4" Do u need to heat up the moulds ? i have heated a little but without succes maybe i should try with making this mould in aluminium but i think the problem would be the same. any help would be great ! thanks, Jonathan
