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 parts. ✅ Consistent production system from mold making to processing such as plating in-house. ✅ Both domestic and overseas factories have obtained ISO9001 certification, ensuring reliable quality management. With ultra-fine molding technology, we can also create miniature tools that move just like the real thing, measuring 25mm in length. (Such as scissors, calipers, cutters, etc.) From limited small lot products to repeat mass production, we can propose mold cost plans tailored to your needs. We have also succeeded in reducing costs through bold design changes from the mold making stage with in-house production. Please feel free to contact us through our website.

Applications/Examples of results
■Transition from Machined Products to MIM Manufacturing for Cost Reduction and Improved Lead Time Previously, we used machined products, but by switching to MIM (Metal Injection Molding) manufacturing, we have improved mass production capabilities and lead times. Additionally, we are reducing material weight to achieve cost savings wherever possible. ■Manufacturing All Types of Medical Device Components A component for grasping cells inside the body during surgery, measuring 5mm in length, produced using MIM technology. The holes achieve a tolerance of 0.01mm with MIM material, and it was completed without any machining. We were able to significantly reduce costs for a product that would have been 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. 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.
