Castem Co., Ltd. showcases ultra-fine processing technology at MECT2025, featuring an exhibition of miniature surgical instruments and mold processing demonstrations.

High-level quality developed independently! 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 continued to respond to customer inquiries for manufacturing everything from simple shapes to challenging designs, with a track record of over 35,000 types of precision metal parts across various industrial sectors. 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-duralumin aluminum materials (A7075 optimized for original casting), and we continue to challenge ourselves with new materials. 【Castem's Lost Wax】 - Capable of mass-producing 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 steel, stainless steel, copper alloys, and aluminum alloys can be freely selected. - Compared to other casting methods, it offers high precision and reduces the number of processing steps. *For more details, please refer to the related link page or feel free to contact us.

Zero mold cost for rapid casting: Prototype verification with "Digital Cast"

Features of "Digital Cast," a mold-less casting that combines precision casting and 3D printing technology ✅ Low-cost casting possible from a single piece without molds ✅ Shortest delivery time of 5 days! Providing metal parts in a short timeframe ✅ Excels in complex three-dimensional shapes and hollow structures ✅ Compatible with a variety of steel types, including ultra-high-strength aluminum alloy A7075 A new casting technology that takes the best of both worlds: the speed of 3D printing and the precision casting that accommodates complex shapes and diverse steel types! There are over 2,000 implementation cases across various industries, including next-generation mobility, rockets, and robot parts. When considering repeat mass production in casting, prototype production using the same material in the casting method is possible. This is ideal for evaluating and verifying mechanical properties! Additionally, it allows for comparative testing of the same shape with various metal materials and can quickly respond to shape changes. A new approach to prototype development of metal parts.

"With high-precision dimming settings of 256/1000 gradations, you can achieve your desired results." The new 1-channel dedicated model LLBLM-A maximizes the performance of high-brightness LEDs. It offers high light stability through constant current control and flexibly accommodates a wide range of inspection and lighting applications with three types of interfaces: parallel, RS232C, and LAN. In addition to intuitive operation via the front panel, it supports high-precision dimming with 256/1000 gradations (256 gradations in parallel mode). The available emission colors are G (green) and B (blue). This new model balances stable light output with ease of use. For more details, please feel free to contact us.

Last month, we held a winter safety conference organized by our company. We have compiled the details and atmosphere of the day, as well as information on winter labor accidents, into a PDF. We would appreciate it if you could take a moment to read it.
