MIM method that excels in producing finely detailed complex shapes with excellent strength.
A case where switching from cutting processing to MIM manufacturing improved mass production and reduced lead time. By reducing material weight by nearly 90g through hollowing, cost reduction was also achieved. Since product weight significantly impacts costs in MIM, we hollow out as much as possible. 【Product Overview】 Material: SUS304L Size: 40×35×35 【Castem's MIM Manufacturing Method】 ✅ Wide range of support from 10 pieces to tens of thousands ✅ In-house mold production allows for proposals to reduce initial mold costs ✅ ISO9001 certified for both domestic and overseas factories ✅ Wide range of materials beyond standard MIM materials, including iron, stainless steel, and titanium ✅ Capable of integrated production including precision machining, heat treatment, and plating ✅ Suitable for weights from below 1g to 100g (thickness from 0.2mm to 5mm, sizes from a few mm to approximately φ50-80) Numerous achievements in medical device parts, male/female screws, inner tubes, side pushers, etc. For small metal parts manufacturing, please feel free to contact us.

basic information
The MIM (Metal Injection Molding) process is a manufacturing method that involves mixing metal powder with an organic binder (resin) and injecting it into a mold to produce metal parts in the desired shape. It excels in creating fine three-dimensional complex shapes with wall thicknesses of up to 5 mm and a density of over 95%. It can accommodate orders in the million range and offers superior mechanical strength compared to conventional sintered products. The company is also advancing the in-house development of compounds made by mixing metal powder and binder, having obtained a U.S. patent in 1991. For orders of 50 shots or fewer, the shortest delivery time for materials is 30 days, and 45 days when including processing. The mold cost starts from around 190,000 yen and includes "trial molds."

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.
