Even small lots can be MIM-processed for small parts!!
The introduction of a small lot compatible MIM (Metal Injection Molding) trial mold! We can accommodate limited items of less than 100 pieces with MIM! Mold costs start from 190,000 yen, making ultra-small lots possible! For more details, please contact us. 【What is MIM technology?】 MIM (Metal Injection Molding) technology is a method for producing metal products by mixing metal powder with a binder, injecting it into a mold, and finally sintering it. Castem was quick to focus on metal injection molding technology, independently conducting research and development without relying on technology imports from the United States, and completed the MIM method with a patent obtained in the U.S. in 1991. We handle thin-walled small parts and complex-shaped metal products with a consistent system from mold production to raw material production at our various factory locations.

We manufacture all types of medical device components. The image product is a 5mm long component made using the MIM process, designed to grasp cells inside the body during surgery. The holes achieve a tolerance of 0.01mm with MIM material, and were produced without machining. This significantly reduced costs for a product that would be very expensive if machined.

A total of 12 types of tools, including calipers and scissors, are perfectly recreated in a miniature size of approximately 25mm. The details, such as the texture of the handles and tips, are crafted without cutting corners, resulting in a level of precision that will resonate with those who regularly use tools. Just like real tools, they are made from "alloy tool steel" and "stainless steel," demonstrating a commitment to quality materials.

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.
