What should be paid attention to in the mold design process?
(1) wall thickness should be uniform and consistent as far as possible, and the parting Angle should be large enough.
(2) transition part step by step, smooth transition and prevent sharp Angle.
(3) the gate.The runner should be as wide and short as possible, and the gate location should be set according to the contraction and condensation process. If necessary, the coolant well should be added.
(4) the mold surface is smooth and low roughness (0.8 is the best)
(5) vent holes and grooves must be sufficient to discharge air and gases in the melt.
(6) except PET, the wall thickness should not be too thin and should not be less than 1mm in general.
