CASTEM Company Overview

A lost-wax precision casting company with 55 years of experience. With technology that has been elevated by "one more 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. 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.
