Plastic injection mould making flow
Plastic injection mould making flow could be consider into: Mould Design-Mould Making-Mould Trial-Mould Packing & Shipping.
When you have a idea, and want to make it in real in to plastic. You could make 3D printing first to see what it is. After that it is time to make mould for it, if you want to make mass molding production.
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.
Plywood for packing and 2D, 3D Mould drawing and electronic copper should be together with mould shipping.
