Hot Chamber & Cold Chamber& Die Casting& Investment casting
Cold & Hot chamber die casting
The molten metal is poured into the shot chamber at room temperature, which is suitable for alloys with higher melting points such as aluminum, magnesium, and copper. It is divided into horizontal cold chamber die casting and vertical cold chamber die casting. The horizontal type is more widely used, featuring high production efficiency and good casting quality.
- Castings have high dimensional accuracy (IT10-IT13) and good surface finish (Ra1.6-6.3μm), which can be directly used for assembly;
- Mainly applicable to low-melting-point non-ferrous alloys (aluminum, zinc, magnesium alloys), not suitable for high-melting-point metals (e.g., steel, cast iron).
High-pressure die casting (HPDC)
-
- Uses high pressure to rapidly inject molten metal into a metal die cavity. Suitable for aluminum, zinc and other alloys for high-volume production — short cycles, smooth surface finish, and high dimensional accuracy.
Low-pressure die casting (LPDC)
- Slowly pushes liquid metal into the cavity from the bottom under low pressure. Produces fewer gas porosities and higher density, suitable for thicker-walled aluminum parts requiring better structural integrity.
Gravity die casting (Permanent mold casting)
-
- Relies on gravity to pour molten metal into a reusable metal mold. Lower tooling costs than HPDC, suitable for medium-volume production and larger or thicker parts, with better mechanical properties than high-pressure die casting.
Vacuum die casting
- Injects metal under vacuum or reduced pressure to minimize gas entrapment and shrinkage, improving internal density and surface quality — used where structural integrity is critical.
Stereolithography (SLA)
Investment casting + Wax mold casting
- A pattern (wax pattern) identical in shape to the part is made from fusible materials (such as wax or plastic). The wax pattern is coated with multiple layers of high-temperature-resistant and hardened to form a shell (mold shell). The wax pattern is then melted out by heating to create a hollow mold, and finally, molten metal is poured to obtain the casting.
Can cast extremely complex parts (e.g., structures with internal cavities, fine holes, or patterns) with high detail reproduction;

As machined
As machined finish is a raw finish that displays machining marks from the machining process. As standard we machine to 3.2Ra, however you can specify the surface roughness down to 0.2Ra.
ADC 12
Polishied/No visible marks.
A380
Visible tooling marks.
Laser engraving is a non-contact, precision surface processing technology that uses a high-energy laser beam to ablate, melt, or change the color of the material surface, thereby forming permanent marks, patterns, or textures.

Passivation
The color is most “close to the base material’s original color” and hard to distinguish solely by color.Passivation is a surface treatment process designed to enhance the corrosion resistance of metals—most commonly stainless steel, but also applicable to aluminum, titanium, and other alloys. Its core principle is to create a thin, stable, and inert “passive film” on the metal surface, which acts as a barrier against environmental factors (e.g., moisture, oxygen, chemicals) that cause rust or corrosion.

Painting/Coating
Powder coating is a dry finishing process used to apply a durable, decorative, and protective layer to a wide range of materials—most commonly metals (e.g., steel, aluminum), but also some plastics, wood, or glass. Unlike liquid paints (which contain solvents that evaporate during curing), powder coating uses finely ground particles of resin and pigment that are electrostatically charged, sprayed onto a surface, and then “baked” to melt and fuse into a smooth, uniform film. This process produces a coating that is far more resistant to chipping, scratching, fading, and corrosion than traditional liquid finishes.

Painting is a process that forms a continuous, uniform film on the surface of substrates (such as metals, plastics, wood, concrete, etc.) using liquid or paste-like paints. Its core purposes are to achieve three key functions: decorative enhancement, protective shielding, and functional reinforcement.
