Plastic Mold Design Checklist for Custom Parts
Plastic Mold Design Checklist for Custom Parts
A good mold design checklist helps reduce trial loops, improve part quality and keep injection production stable.
Check the part structure first
Wall thickness, ribs, bosses, snap fits, draft angles and parting line should be reviewed before mold design. These details affect filling, ejection and final appearance.
Review gate, cooling and ejection
Gate position, cooling layout and ejection design directly influence cycle time, warpage, sink marks and dimensional stability.
Plan maintenance early
Molds that are easy to clean, inspect and maintain are more reliable during repeat production orders.
