Screws are also shaped without machining! Leave the fine, thin-walled, and complex-shaped micro metal parts to us.
MIM (Metal Injection Molding) is a technology for manufacturing metal parts by mixing metal powder and binder, injecting them into a mold, and finally sintering them. ✅ Capable of producing fine, complex shapes and sharp edges with a minimum wall thickness of 0.1mm. ✅ Can mold screws and ultra-fine pins without machining. ✅ Proven track record in medical devices, dental, food, and aerospace-related components. ✅ Integrated production system from mold manufacturing to processing such as plating in-house. ✅ Both domestic and overseas factories have obtained ISO9001 certification, ensuring reliable quality control. With ultra-fine molding technology, we can also create miniature tools that move like the real thing, measuring 25mm in length (such as scissors, calipers, and cutters). From limited small lot products to repeat mass production, we can propose mold cost plans tailored to your needs. We have successfully achieved cost reductions through bold design changes from the design stage, with in-house integrated production from mold manufacturing.

Applications/Examples of results
■Transition from Machined Products to MIM Manufacturing for Cost Reduction and Improved Lead Time Previously, products were made through machining, but by switching to MIM (Metal Injection Molding) manufacturing, mass production efficiency has improved and lead times have been reduced. Additionally, by reducing material weight, we have also achieved some cost savings. ■Manufacturing All Types of Medical Device Components A component that grips cells inside the body during surgery, measuring 5mm in length, produced using MIM technology. The holes achieve a tolerance of 0.01mm with MIM materials, completed without machining. We were able to significantly reduce costs for products that are very expensive to produce through machining. *For more details, please refer to the related links page or feel free to contact us.

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.
