What Problems Should Be Paid Attention To in The Process of Mold Design?

1.the wall thickness should be as uniform as possible, and the demoulding slope should be large enough.

2.the transition part should be gradually, smooth transition, to prevent sharp corners.

3. Gate. The runner should be as wide and short as possible, and the gate position should be set according to the shrinkage condensation process, and the cooling well should be added if necessary.

4. mold surface should be smooth, low roughness (preferably low 0.8)

5.the exhaust hole, the groove must be enough to discharge the air and the gas in the melt in time.

6. in addition to PET, the wall thickness should not be too thin, generally not less than 1mm.
