What should be paid attention to in mold design?

Generally, attention should be paid to the following points when designing mould.

The thickness of the wall should be as uniform as possible, and the release angle must be large enough.

The transition should be gradual. Smooth transition to prevent sharp corners. Sharp edges, especially PC products, must not be chipped.

Gate. The runner should be as wide and thick as possible, and the gate location should be set according to the shrinkage and condensation process. If necessary, the cold feed well should be added.

The surface of the mold should be smooth and the roughness is low (preferably below 0.8).

Exhaust holes. The slot must be enough to discharge air and melt gas in time.

In addition to PET, the wall thickness should not be too thin, generally not less than LMM.
