For lightweight and mass production of small metal parts, choose MIM (Metal Injection Molding).
From medical device parts to dental and aerospace components. High-precision parts with fine details without machining.
"I want to make it lighter." "The costs and delivery times don't match with machining." ―― We solve such "big challenges of small parts" with MIM. 【Strengths of Castem MIM】 ✅ Proficient in fine, thin, and three-dimensional shapes Achieving complex three-dimensional shapes that are difficult with machining through high-precision metal powder injection molding. High mechanical strength is realized despite being sintered products. ✅ Cost optimization through processing-free design Numerous achievements in high-precision shapes that require no secondary processing, such as screws, medical devices, and orthodontic parts. With a "non-cutting" mindset from the design stage, bold weight reduction and lightening are possible. ✅ Consistent support from mold to mass production Molds are designed and manufactured in-house. Stable mass production is achieved at our ISO9001 certified overseas factory, pursuing a balance between quality and cost. Shortening processes, improving quality, and reducing weight―― Castem proposes the "optimal shape" tailored to our customers' challenges. If you are looking to lighten and mass-produce small metal parts, please consult us. ☞ For more details, please contact us through the official Castem website.

Company information
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.
