キャステム List of Products and Services

Castem's core technology is "lost wax precision casting," which excels in producing complex three-dimensional shapes. Since our founding, we have continuously responded to customer inquiries for manufacturing everything from simple shapes to challenging designs, with over 35,000 successful cases. In response to various demands for metal materials, we have started handling over 70 types of steel, including stainless steel, copper, and aluminum. We also accommodate special steels and unique ultra-high-strength duralumin (A7075 optimized for original casting), and we continue to challenge ourselves with new materials. 【Castem's Lost Wax】 - Higher precision and beautiful casting surfaces compared to other casting methods, allowing for a reduction in processing steps. - Capable of mass production of complex shapes and three-dimensional curved surfaces at low cost. - There are slight differences depending on the casting material (approximately 12S for small parts, 20S for large parts). - Strength can be freely pursued from two aspects: shape and material. - Special steels, stainless steel, copper alloys, and aluminum alloys can be freely selected. *For more details, please refer to the related link page or feel free to contact us.

The introduction of a small lot compatible MIM (Metal Injection Molding) trial mold! We can accommodate limited items of less than 100 pieces with MIM! Mold costs start from 190,000 yen, making ultra-small lots possible! For more details, please contact us. 【What is MIM technology?】 MIM (Metal Injection Molding) technology is a method for producing metal products by mixing metal powder with a binder, injecting it into a mold, and finally sintering it. Castem was quick to focus on metal injection molding technology, independently conducting research and development without relying on technology imports from the United States, and completed the MIM method with a patent obtained in the U.S. in 1991. We handle thin-walled small parts and complex-shaped metal products with a consistent system from mold production to raw material production at our various factory locations.
