Switching from cutting to MIM manufacturing method increases mass production efficiency and reduces costs!
Machine parts in the million-order range, with numerous achievements in medical device components over more than 30 years. Obtained a U.S. patent through independent development.
The image shows a case where the mass production capability was improved and lead time was reduced by switching the parts, which were traditionally machined, to the MIM (Metal Injection Molding) method. Additionally, by reducing the material weight by nearly 90g through debinding, cost reduction was also achieved. ◎Product Overview - Material: SUS304L - Size: 40×35×35 - In the case of MIM, the product weight significantly affects the cost, so debinding is minimized as much as possible. 【Castem's MIM Method】 The MIM (Metal Injection Molding) method is a processing technique that involves mixing metal powder with an organic binder (resin) and injecting it into a mold to manufacture metal parts in the desired shape. It excels at producing fine three-dimensional complex shapes with a wall thickness of up to 5mm and achieves a density of over 95%. It can accommodate million-order quantities and has superior mechanical strength compared to conventional sintered products. We are also advancing the in-house development of compounds made by mixing metal powder and binder, and we obtained a U.S. patent in 1991. If you have any inquiries about the manufacturing of small metal parts, please feel free to contact us.

basic information
【Features】 ■ For orders of 50 shots or fewer, the shortest delivery time for materials is 30 days, and 45 days when including processing. We also handle "trial molds" with a cost estimate starting from 190,000 yen. We can accommodate a wide range of lot sizes from 10 pieces to tens of thousands. ■ Over 90% of production is carried out at our wholly-owned overseas factories. We manufacture molds in-house and can propose cost reduction strategies for initial mold costs. ■ Both domestic and overseas factories are ISO 9001 certified. We implement quality control under a robust management system. ■ We accommodate a wide range of materials beyond standard MIM materials, including iron, stainless steel, and titanium. ■ We offer integrated production capabilities, including precision machining, heat treatment, and plating. ■ We can handle weights from under 1g to 100g (with thicknesses from 0.2mm to 5mm, and diameters of approximately 50 to 80mm).

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.
