Zinc is a material suitable for casting complex shapes and parts with high dimensional accuracy because it melts at relatively low temperatures, allowing for good flow and excellent workability. For this reason, "zinc die casting" features the ability to produce precise castings with good reproducibility of designs, ranging from simple designs to complex shapes. Additionally, one of its characteristics is that the mold life is longer compared to aluminum die casting. The surface of the material is easy to treat with surface treatments such as plating and painting, allowing for the production of various beautiful products made from chrome, nickel, copper, gold, silver, and more. [Features] - Excellent workability - Capable of manufacturing parts with extremely high dimensional accuracy in complex shapes and advanced thinning - The surface of the material is easy to treat with plating and painting - The casting temperature is relatively low, resulting in a longer mold life compared to aluminum die casting *For more details, please feel free to contact us.

"Brass die casting" is a material that is highly durable and resistant to breaking due to its strong ductility. It is utilized in components such as breaker terminals, taking advantage of its excellent conductivity. Additionally, it is often used in high-end Buddhist altar fittings, and even if the plating comes off, the texture of the material itself remains intact. Our company is flexible in accepting small lot orders. 【Features】 ■ Yellow and resistant to rust, easy to cast and process ■ Strong ductility, making it resistant to breaking and highly durable ■ Often used in high-end products in small lots ■ Excellent electrical conductivity ■ The texture of the material remains intact even if the plating comes off *For more details, please feel free to contact us.
