Achieve 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, there are no burrs inside, and it possesses the necessary strength to prevent chipping or breaking. When dealing with multiple pieces of this shape on a pin cushion through machining, the cost and time are significantly high. With our MIM technology, which allows for ultra-small precision molding, high-precision parts under 1 mm can be mass-produced without machining. 【What is MIM (Metal Injection Molding)?】 It is a method also known as metal powder injection molding. A mixture of metal fine powder and a binder is injected into a mold to create a shaped product, which is then subjected to debinding and high-temperature sintering in a vacuum furnace to produce metal products. We excel at 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 will provide the best proposals for our customers using 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. 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.
