A mold ( or a mould ) is a hollow container used to give shape to molten or hot liquid material when it cools and hardens.
With a mold, we produce prototypes with the ability to duplicate or simulating plastic or metal physical properties.Then we proceed with mass production which is also called injection.
Compared to CNC prototype, when your demanded quantity is high enough, you can choose a mold and injection instead of mockups for cost down quite substantially.
Or after several stages of the trial run (EVT, DVT, PVT) by verifying CNC prototypes, your masterpiece will enter into mass production stages then officially launched on the market.
The types are divided into knife one, soft-tooling one and hard-tooling one( steel mould ). Briefly introduce them below.
