High-level quality developed in-house! Compatible with over 70 types of steel, with more than 35,000 proven models. We propose the optimal shape and material according to your application.
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.

Lost wax is a friend to designers. Parts made through precision casting have the potential to enhance the performance of the entire machinery and equipment being produced. - Freedom of shape (lightweight, design flexibility, no machining, no welding integration) - High strength - Beautiful appearance - Freedom of material (as long as it can be dissolved in the atmosphere, including copper, aluminum, stainless steel, and special materials)

■Shape Change and Optimization We used to manufacture by conventional cutting and assembly (welding), but we proposed integration through lost wax casting. Furthermore, we optimized the shape to match the object and produced a sample using a 3D printer. You were able to see the actual size sample and confirm the situation with the object. Material: SCS13 Size: 70×40×35

■From Machined Products to Lost Wax Method Previously, we used machined products, but by switching to manufacturing with the lost wax method, we have improved mass production capabilities and reduced lead times. Additionally, by removing unnecessary areas, we are achieving weight reduction and reducing material costs. Furthermore, we are minimizing processing surfaces to keep processing costs down while maintaining quality. Material: S45C (Precision Casting) Size: 90×70×31

Company information
With a posture of "just half a step" without complacency, we have cultivated "lost wax precision casting" over many years. In 1991, we obtained a U.S. patent for "MIM (Metal Injection Molding)." Utilizing 3D printing technology, we offer next-generation precision casting technology called "Digital Cast." We provide optimal proposals through various technologies! We thoroughly support our customers' manufacturing processes! We specialize in complex three-dimensional shapes in small lots of various types and carry out everything from mold making to casting, machining, and simple assembly in-house. We supply products to various industries, including medical devices, semiconductors, machine tools, and aerospace. "Just make it, from one piece." We can propose a wide range of manufacturing methods from prototype production of one piece to mass production. We enable time savings in searching for various suppliers and considering consultation destinations, becoming a true total cost reduction partner by proposing reductions in management costs associated with consideration time and product costs. More than half a century ago, Castem's casting began with handmade machine tools. Today, we have become a company with the top domestic share in the manufacturing of general industrial parts using lost wax and are also engaged in the production of micro lenses and micro needles using the world's highest precision 3D light shaping technology.
