We can accommodate a wide range from 10 pieces to tens of thousands! We have our own mold factory with a monthly capacity of 70 types!
The "Metal Injection Molding" method is a processing technique that creates metal parts in the desired shape by mixing powdered metal with a binder and injecting it into a mold. With a density of over 95% and pores that take on a round, independent shape, it exhibits excellent mechanical strength. The binder debinding process is conducted at high speed to minimize the alteration and deformation of the metal powder, allowing for debinding and sintering under various conditions such as vacuum, reducing atmosphere, inert atmosphere, and high-pressure atmosphere, tailored to the specific requirements of each metal. 【Features】 ■ Small lot products of 3000 pieces or less are handled with low-cost, dedicated molds for small lots. ■ Broad compatibility beyond standard metal injection materials. ■ All processes, including precision machining, heat treatment, and plating, are carried out in-house. ■ Quick response to low-cost, short delivery times, and design changes or corrections. ■ The process is developed internally by our own team. *For more details, please refer to the related link page or feel free to contact us.

■From Machined Products to MIM Manufacturing 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 are also achieving some cost reductions. Material: SUS304L Size: 17×13×8

■We manufacture all types of medical device components. The imaging product is a component that grips cells inside the body during surgery, measuring 5mm in length and made using the MIM process. The holes achieve a tolerance of 0.01mm with MIM material, and were produced without machining. With cutting, we were able to significantly reduce costs for a product that is usually very expensive.
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.
