Cooling channels and cycle time
Even cooling protects dimensions and shortens the cycle.
Cooling dominates most injection cycles. Channel diameter, pitch and layout aim for even cool-down; otherwise warp and dimensional drift rise.
Thick zones and rib roots create hot spots. Baffles, bubblers or conformal approaches are planned when needed; drilled cooling covers many jobs.
Water flow, temperature and clogging risk matter as much as process logs. At T0 we validate cycle with surface temperature and dimensions.
DFM notes cooling access (core / cavity) early; inserts may need independent circuits.
Cooling checklist
- Channel size and distance to part
- Hot spots / thick zones
- Insert cooling needs
- Water temp and flow logging
- Cycle target vs dimensional tolerance
