Mold design is highly valued in the field of industrial machinery today, and its applications are numerous and extensive. There is an injection mold in mold design, which is also a more popular one. However, some problems often occur in injection mold design, so what should we pay attention to?
(1) The wall thickness should be as uniform as possible, and the draft angle should be large enough.
(2) The transition part should gradually and smoothly transition to prevent sharp corners.
(3) Gate. The runner should be as wide and thick as possible, and the gate position should be set according to the shrinkage and condensation process. If necessary, cold wells should be added.
(4) The surface of the mold is smooth and the roughness is low (preferably 0.8)
(5) The exhaust holes and grooves must be sufficient to exhaust the air and gas in the melt.
(6) In addition to PET, the wall thickness should not be too thin, generally not less than 1mm.
