Shenzhen Alu Rapid Prototype Precision Co., Ltd.

Principle: Choose plastic materials that balance prototype requirements with process compatibility and cost.

Details:

Select thermoplastics (e.g., ABS, polycarbonate, nylon, PP) for injection molding to mimic production materials.

Use polyurethane resins for vacuum casting, which simulate properties of thermoplastics (e.g., flexibility, rigidity, or transparency).

Consider specialty plastics (e.g., TPU for flexibility, PMMA for clarity) based on functional or aesthetic needs.

Ensure materials are compatible with the mold material and molding process (e.g., low-temperature resins for silicone molds).

Why It Matters: Ensures prototypes reflect final part properties (e.g., strength, texture) while keeping costs low.

Example: Using polyurethane resin in vacuum casting to simulate ABS for a consumer electronic housing.
