Shenzhen Alu Rapid Prototype Precision Co., Ltd.

Select a casting method based on prototype requirements (e.g., complexity, quantity, and precision). Common methods for aluminum prototypes include:

Sand Casting:

Best for low-cost, simple, or large parts.

Involves creating a sand mold from a pattern.

Suitable for small batches; less precise (tolerances ~±0.5 mm).

Investment Casting (Lost-Wax Casting):

Ideal for intricate, high-precision parts.

Uses a wax pattern coated with ceramic, melted out to form a mold.

Offers tight tolerances (~±0.1–0.2 mm) and smooth finishes.

Die Casting:

Best for high-volume, precise prototypes resembling final production parts.

Uses a steel mold; high initial cost but excellent for complex geometries.

Tolerances as tight as ±0.05 mm.

3D Printed Molds (Hybrid Approach):

Use 3D-printed patterns or molds (e.g., SLA or FDM) for sand or investment casting

Speeds up prototyping; ideal for complex designs.

Recommendation: For prototypes, sand or investment casting is often preferred due to lower mold costs and flexibility for small runs. Shenzhen Alu Rapid’s expertise in CNC machining and 3D printing can support hybrid approaches.
