1, Casting dimension accuracy is high, the general linear tolerance is 1%, angle tolerance: + / - 1/2 degree, surface roughness is Ra 1.6 3.2, material and machining cost can be saved.
2, Complicated shape part is available, multiple complex parts can be casted together to save combination and welding work.
3, Cast LOGO design or letters directly on your parts to improve advertising image.
4, Casting material is properties. Heat resistance, abrasion resistance, corrosion resistance, material hardness can reach to HRC15-60 in order to meet the requirements under various working conditions.
5, QTY is Flexible. From small to large quantitie, casting has high efficiency and good repeatability. Mould or other cost is low at early stage of product development.
Investment casting requires the use of a metal die, wax, ceramic slurry, furnace, molten metal, and any machines needed for sandblasting,
cutting, or grinding.
The process steps include the following:
Pattern creation - The wax patterns are typically injection molded into a metal die and are formed as one piece.
Mold creation - This "pattern tree" is dipped into a slurry of fine ceramic particles, coated with more coarse particles, and then
dried to form a ceramic shell around the patterns and gating system. This process is repeated until the shell is thick enough to
withstand the molten metal it will encounter. The shell is then placed into an oven and the wax is melted out leaving a hollow ceramic
shell that acts as a one-piece mold, hence the name "lost wax" casting.
Pouring - The mold is preheated in a furnace to approximately 1000°C (1832°F) and the molten metal is poured from a ladle into
the gating system of the mold, filling the mold cavity.
Cooling - After the mold has been filled, the molten metal is allowed to cool and solidify into the shape of the final casting.
Casting removal - After the molten metal has cooled, the mold can be broken and the casting removed.
Finishing - Often times, finishing operations such as grinding or sandblasting are used to smooth the part at the gates. Heat
treatment is also sometimes used to harden the final part. Our surface finish are Blacking,polishing,anodization,chrome plating,
zinc plating,nickel plating,tinting. Aluminum alloy die casting powder (powder coating), the lacquer that bake, fuel injection, oxidation,
sand blasting, electroplating, etc. According to the thickness of the product surface treatment, different degree of finish.
