3. Multi-cavity moulded part vs Family moulded part
Mould design is including DFM, Mould Flow Analysis, 2D Mould Layout and 3D Mould Drawing. It is part lay out, part line making, gate design, runner design, gating way, ejection method, cooling layout, etc.
Mould making is based on mould design and purchase mould base, steel and component by machined by CNC, EDM, Lathe, Gun Drill and Milling etc., make mould fitting and mould trial in the end. To see the idea into real by mass production.
Mould trial is the last processing to check if the work is making well. You will get the moulded part to inspection specification. Make decision if itt is ok or NG after mould trial.
