The process of creating diecast models

1. Design

• The process starts with a 3D design using CAD software.

• Every part—body, wheels, interior—is planned out in detail, often based on real vehicles.

2. Tooling & Mould Making

• A metal mould (die) is created, usually from hardened steel.

• This mould has cavities shaped exactly like the car parts and is made in two halves.

3. Die Casting

• A zinc alloy (commonly Zamak) is melted down.

• The molten metal is injected into the mould under high pressure.

• It quickly cools and solidifies into the shape of the car body or other parts.

• The part is removed, and the mould is reused repeatedly.

4. Cleaning & Polishing

• Any excess metal from the casting process is trimmed off.

• Parts are polished or sanded to smooth out imperfections.

5. Painting

• Models are painted in layers—primer, base coat, clear coat.

• Tampo printing is used for detailed markings like logos, lights, and racing stripes.

6. Assembly

• Diecast metal parts are combined with plastic, rubber, and sometimes fabric components.

• Parts like interiors, dashboards, windows, tires, and engines are assembled.

• Moving parts like opening doors, hoods, and steerable wheels are added here.

7. Quality Control & Packaging

• Each model is checked for paint flaws, loose parts, and accuracy.

• Once approved, it's packaged with a collector box and a display stand.
