About the process:

I. Mold design and manufacturing

3D modeling: Design the 3D structure of the motorcycle model through CAD software, and refine it to the frame, engine, wheel hub, seat and other parts to ensure dimensional accuracy (the error is usually controlled within ±0.05mm) and appearance details (such as heat dissipation holes, engraved lines, LOGO).

Mold splitting: According to the model structure, the mold is divided into a fixed mold (fixed end) and a movable mold (movable end). Complex parts need to be designed with sliders (such as openable side covers) or cores (such as hollow structures) to facilitate demolding.

Mold material: High-strength mold steel (such as H13, SKD61) is used, and the hardness is increased by heat treatment (HRC48-52) to ensure resistance to high pressure and high temperature molten metal erosion.

II. Product material preparation:

Processing: Melt the metal ingot into a molten state and degasify it to reduce pore defects.

Customizable materials (non-customized products are configured by default as zinc alloy fuel tank material, fine ABS plastic, and rubber tires):

Zinc alloy: low melting point (about 400-450℃), good fluidity, high-grade texture, suitable for fine structures (such as spoke wheels, engine pipes), but heavy.

Aluminum alloy: low density, high strength, suitable for lightweight models, but high melting point (600-700℃).

Magnesium alloy: the lightest metal material, used for high-end collectibles.

III. Die casting

High-pressure injection: molten metal is injected into the mold cavity under high pressure (50-100MPa), with an extremely short filling time (0.01-0.2 seconds) to ensure clear details.

Cooling demolding: The mold is cooled by water or air, and after the metal solidifies (several seconds to tens of seconds), the dynamic mold is separated and the ejector pushes out the blank.

Blank features: surface roughness Ra≤1.6μm, dimensional accuracy up to IT11-IT13, can directly form threads, buckles and other structures.

IV. Post-processing process

Deburring and finishing: Manual and mechanical (sandblasting, roller) to remove flash, polish the water nozzle (gate residue), and ensure smooth surface.

Defect repair: repair defects such as shrinkage holes and pores (such as low-temperature solder for zinc alloy) or fill with putty, and then polish flat.

Machining: drilling (such as installing shaft parts), tapping (fixing screws), CNC milling (high-precision surface, such as instrument panel scale).

V. Surface treatment and assembly

Surface treatment

Electroplating: nickel plating, chrome plating (simulating metal parts, such as exhaust pipes, handlebars), improve gloss and corrosion resistance.

Spray painting: primer (enhanced adhesion) + topcoat (metallic paint, matte paint, etc., simulating real car paint), partial cover spray painting pattern (such as car body decals).
Water transfer printing/stickers: complex patterns (such as carbon fiber textures and trademarks) are achieved through water transfer printing, and details (such as dashboard pointers) are embellished with pad printing or stickers.

Assembly: Die-cast parts (fuel tank, frame, wheels) and non-metallic parts (plastic transparent parts, rubber tires, metal springs) are combined through screws, glue or buckles. Some high-end models contain movable structures (such as shock absorbers and steering).
