For lightweight and mass production of small metal parts, choose MIM (Metal Injection Molding).
From medical device components to dental and aerospace parts. High-precision components 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】 ✅ Expertise in fine, thin, and three-dimensional shapes High-precision metal powder injection molding allows for the integral shaping of complex three-dimensional forms that are difficult to achieve with machining. Achieves high mechanical strength despite being a sintered product. ✅ Cost optimization through machining-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" approach from the design stage, bold thinning and weight reduction are possible. ✅ Comprehensive support from mold design 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're 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. 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.
