How do you choose the processing method of a prototype?
There are many processing methods for prototypes, such as CNC machining, 3D printing, Vacuum forming, Prototype Injection molding, etc. What kind of prototype processing method is more suitable? How do customers choose the type of prototype? This is the problem that customers need to face when developing testing and proofing.
3D Printed Prototypes
A fast and inexpensive way to get physical 3D models for basic validation, but the Limited choice of materials and properties often differ from true production plastics. It is useful for visual models but less so for functional testing.
CNC Machined Prototypes:
Machining production-grade plastics allows functional testing and excellent dimensional accuracy for tolerance validation. CNC machined prototypes are made by CNC, not by the injection molding process, so they can’t be used in validating the material properties, mold flow, and modality.
Injection molded prototypes:
Molded prototypes are made in the same condition as Mass Production, So the accuracy of the molded prototypes is almost the same as the mass-produced parts. It is ideal for the proofing of key components and precision structural parts.
In addition to proofing testing and inspection purposes, Injection molding prototypes are also suitable for small batch production to achieve rapid market development products.
