キャステム Company Profile

A lost-wax precision casting company with 55 years of experience. With technology that has been elevated by "half a step," we empower the people who create things.

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.
