寿金属工業 List of Products and Services

Our company conducts "aluminum die casting." Die casting refers to the combination of die + casting. In die casting, molten metal is injected into a mold under pressure. Due to the application of pressure, there are advantages such as high dimensional accuracy and a clean surface finish of the products. [Features] ■ Molten metal is injected into the mold under pressure ■ High dimensional accuracy due to the application of pressure ■ Clean surface finish of the products *For more details, please refer to the PDF document or feel free to contact us.

• Contract manufacturing

Our company conducts "gravity casting." Gravity casting is a method where a molten metal supply port is provided at the top of the mold, allowing the molten metal to fill the mold from top to bottom under the influence of gravity. By using sand cores, it is possible to manufacture complex shapes. 【Features】 ■ A method where a molten metal supply port is provided at the top of the mold, allowing the mold to be filled from top to bottom by gravity. ■ The use of sand cores enables the production of complex shapes. *For more details, please refer to the PDF document or feel free to contact us.
