Castem's proprietary technology patented in the United States.
Metal injection molding is a processing method that creates metal parts of desired shapes by mixing powdered metal with a binder and injecting it into a mold. Recognizing the rapid trend towards high precision and complex shapes, Castem foresaw this shift early on and focused on the metal injection molding method (MIM), conducting independent research and development without relying on technology imports from the United States. In 1991, they obtained a patent in the U.S. and completed the manufacturing process using metal injection. Since then, they have continued to explore the possibilities of metal injection and have taken on the development of mechanical parts that can only be made through this method. Moving forward, they aim to further enhance their capabilities and respond to the demands for higher precision and complex shapes. For more details, please contact us.

■From Machined Products to MIM Manufacturing Previously, we used machined products, but by switching to MIM (Metal Injection Molding) manufacturing, we have improved mass production capabilities and reduced lead times. Additionally, we are also achieving cost reductions by reducing material weight. Material: SUS304L Size: 17×13×8

We manufacture all types of medical device components. The image product is a part that grips cells inside the body during surgery, measuring 5mm in length and made using the MIM process. The holes achieve a tolerance of 0.01mm with MIM material, and it was completed without machining. In cutting, we were able to significantly reduce costs for a product that is typically very expensive.
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.
