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 parts that were traditionally machined to the MIM (Metal Injection Molding) method. Additionally, by reducing the material weight by nearly 90g through a process called "de-bulking," 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 de-bulking is done as much as possible. 【Castem's MIM Method】 The MIM (Metal Injection Molding) method is a processing technique that mixes metal powder with an organic binder (resin) and injects it into a mold to produce metal parts in the desired shape. It excels in producing fine three-dimensional complex shapes with a wall thickness of up to 5mm and achieves a density of over 95%. It can accommodate orders in the millions 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 obtained a U.S. patent in 1991. If you have any inquiries regarding 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 if processing is included. We also handle "trial molds" with a mold cost estimate starting from 190,000 yen. We 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 reductions in initial mold costs. ■ Both domestic and overseas factories have obtained ISO 9001 certification. 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 for precision machining, heat treatment, plating, etc. ■ We can handle weights from under 1g to 100g (with thicknesses from 0.2mm to 5mm, and diameters of several mm to approximately φ50-80).

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.
