We optimize the manufacturing method and shape according to the application [Lost Wax Example].
We propose the optimal shape along with 3D printed products. We provide thorough support from your prototypes to mass production!
The image shows an example of parts that were originally manufactured through cutting and welding, now integrated using lost-wax precision casting. Furthermore, the shape has been optimized, and a sample was produced using a 3D printer. You were able to see the full-scale sample in person and confirm its situation with the object. Material: SCS13 Size: 70×40×35 【Castem's Lost-Wax Method】 Castem's core technology, "lost-wax precision casting," excels in producing complex three-dimensional shapes. Since our founding, we have continued to respond to customer inquiries for manufacturing from simple shapes to challenging ones, with over 35,000 molds produced. In response to various requests for metal materials, we now handle more than 70 types of steel, including stainless steel, copper, and aluminum. We also accommodate special steels and unique ultra-high-strength aluminum materials (A7075 optimized for original casting), and we continue to challenge ourselves with new materials. In addition to cost reduction, we consider flow of molten metal and production efficiency, proposing shapes and methods tailored to specific applications. For precision metal parts, please feel free to consult with Castem.

basic information
【Castem's Lost Wax】 ■ Complex shapes and three-dimensional curved surfaces can be mass-produced at low cost. ■ There are some 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 can reduce the number of processing steps.

Company information
With a posture of "just half a step" without complacency, we have cultivated "lost wax precision casting" over many years. Utilizing 3D printing technology, we offer next-generation precision casting technology called "Digital Cast." We obtained a U.S. patent for "MIM (Metal Injection Molding)" in 1991. We provide optimal proposals using various technologies and thoroughly support our customers' manufacturing! 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 an integrated in-house system. 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 also 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 related to consideration time and product costs. More than half a century ago, Castem began its casting business by handcrafting machine tools. Today, we have become a leading company in Japan for manufacturing general industrial components using lost wax casting and are also engaged in the production of micro lenses and micro needles using the world's highest precision 3D light shaping technology.
