Achieving extremely small and complex shapes without machining! Please feel free to contact us regarding metal parts.
A small-diameter hole shaped like a conical tube, with a tip diameter of φ0.3±0.05 and a length of 2.8 mm, has been achieved without machining. Additionally, it has no burrs inside and possesses the necessary strength to prevent chipping or breaking. When dealing with multiple pieces of such shapes on a needle holder through machining, the cost and time are significantly high. With our MIM technology, which allows for ultra-precision molding, high-precision parts under 1 mm can be mass-produced without machining. 【What is MIM (Metal Injection Molding)?】 It is a manufacturing method also known as metal powder injection molding. This process involves injecting a mixture of metal fine powder and a binder (adhesive) into a mold, then removing the molded product and performing debinding and high-temperature sintering in a vacuum furnace to create metal products. We specialize in obtaining ultra-small metal parts with high precision, complex shapes, and three-dimensional geometries that are difficult to machine. Our company is the only one in Japan that develops the raw materials used for MIM in-house. We offer the best proposals for our customers through various technologies. Please feel free to contact us through our website for any inquiries regarding metal parts.

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.
