"Castings are not suitable for prototyping or small lot production." —Don't you think so? With Castem's "Digital Cast," you can produce casting parts from just one piece without molds by utilizing 3D printing. The freedom of shape is also high, and you can significantly reduce lead time, costs, and labor. 【Cost Reduction Example】 The part in the thumbnail is a CG manifold that was previously made by machining two parts and then welding them together. Additionally, due to the special material Inconel 625, it was sourced from overseas processors, making it a quite costly part in the past. However, by creating it as a single molded piece, we achieved a cost reduction of up to 80% and improved strength. "Shapes that cannot be achieved by machining" and "I want to verify with the same material as the final product." We can solve such concerns in the development field with next-generation precision casting technology, Digital Cast. If you have 3D data, just leave the rest to us. We will provide precision cast products quickly!

Parts that are being machined and assembled may have the potential for cost reduction. By integrating shapes made up of numerous parts, we aim to achieve cost reduction. It is also possible to reduce weight and costs by eliminating joint areas that were necessary for assembly. 【Shape】 Complex shapes and those with three-dimensional curved surfaces can be mass-produced at low cost. 【Material】 You can freely choose from special steel, stainless steel, copper alloys, and aluminum alloys. Additionally, material changes can be made using the same mold, making it easier to compare and evaluate during the prototype stage. 【Strength】 Since adjacent parts and attached components can be integrated and cast, we can eliminate weak points caused by assembly and welding. For movable parts, weight reduction can eliminate unnecessary inertial forces, increasing durability. Thus, strength can be freely pursued from both shape and material perspectives. 【Casting Surface】 There may be slight differences depending on the casting material, but small parts are around 12S, and large parts are around 20S. 【Precision】 Compared to other casting methods, the precision is high, allowing for a reduction in the number of machining processes. We will consider and propose appropriate shapes together, so please feel free to consult with us first.

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.
