What drives cycle time in thin-wall packaging molds

In thin-wall packaging, cycle time is set by how fast heat can leave the part, not by how fast the press can run.

Cooling layout

Cooling channels need to follow the part geometry closely. Where they run far from the cavity surface, the part stays hot and the cycle stretches out.

Wall thickness

Thinner walls cool faster but need higher injection pressure and a stiffer tool. The right balance depends on the part and the resin.

Ejection

A part that sticks costs more than a part that cools slowly. Draft, surface finish and ejector layout all have to be designed for release from the first shot.

Cycle times, cavitation counts and wall-thickness limits are pending confirmation from the factory.
