The cavity must fit another core, The designer should pay attention to this point. 3, Please carefully check the data of color injection molding machine such as maximum mold thickness. The minimum allowable mold thickness, K.O. holes distance etc.. 4, gate should be cut automatically in plastic moulding company plate Bicolor mold, especially soft resin. 5, When we design the second injection cavity. We should leave some space to avoid scratch but must think about the seal area, the molding part has the possibility of deformation and cause flash. 6, We can make the first molding part a little bit bigger than spec.It will be pressed tighter when the second injection, reduces the risk of flash.
