 Prototype
Prototype can help us to test the design idea is correct or not. And can modify the design relatively after testing the prototype parts. It can reduce unnecessary cost and save time for customer to earn the market.
Model machining has two types: ： handwork model ，digital
model
Digital model ： CNC machining ， RP(Rapid Prototyping)
