Start from the main pull direction
Review projection direction, deep cavities, cosmetic surfaces and draft angle first. Straight pull structures usually reduce cost and maintenance risk.
Why venting matters
Venting removes air and gases from the cavity, reducing burn marks, short shots, weak weld lines and local high pressure.
Gate and ejection marks need planning
Gate marks, ejector marks, slide lines and parting lines should avoid cosmetic, sealing and datum surfaces when possible.
Think about manufacturing and maintenance
Deep narrow cavities, sharp corners and polishing blind areas increase machining difficulty. Wear areas should be replaceable inserts when possible.
