Over 70 types of diverse steel grades. Based on more than 35,000 models of achievements, we will provide the best proposals!
We need precision parts, but machining is costly... Multiple processes such as machining and welding are required, making it labor-intensive... We want to integrate multiple parts... Why not solve these concerns with 【Lost Wax Precision Casting】? 【Castem's Lost Wax Method】 "Lost Wax Precision Casting" specializes in complex three-dimensional shapes. Since our founding, we have continuously responded to customer inquiries for production, achieving over 35,000 types from simple to complex items. In response to various material requests, we have started handling over 70 types of steel, including stainless steel, copper, and aluminum. We also accommodate special steels and ultra-high-strength aluminum alloys (optimizing original casting for A7075). 【Cost Reduction Examples】 The thumbnail shows a cost reduction case achieved by changing the manufacturing method to lost wax casting, resulting in shape modification and integration. In conventional products, we manufactured through multiple processes including laser cutting, bending, machining, and welding, but we proposed integration using the lost wax method. This eliminates the hassle of managing processes between steps, reduces machining, and increases strength. By confirming the contact surface with the object and making that part convex, we reduced the dimensional management range, making quality control easier.

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.
