Examples of switching from cutting processed products to MIM manufacturing method for time reduction and cost reduction.
Improving mass production increases lead time reduction! Achieving cost reduction through weight reduction as well!
Traditionally, it was a machined product, but by switching to the MIM (Metal Injection Molding) manufacturing process, mass production efficiency has improved and lead times have been reduced. Additionally, we have achieved cost reductions by reducing the material weight by nearly 90g. 【Castem's MIM Process】 The "Metal Injection Molding" process is a manufacturing method that creates metal parts of the desired shape by mixing powdered metal with a binder and injecting it into a mold. With a density of over 95% and pores taking on a round, independent shape, it exhibits excellent mechanical strength. The binder debinding process is performed at high speed to minimize the alteration and deformation of the metal powder, allowing for 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 fewer than 3,000 pieces are handled with low-cost dedicated molds. ■ Wide 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 lead times, and design changes. ■ We have a system in place to develop the processes in-house.

Applications/Examples of results
■Machine Parts We accommodate a variety of metal components such as irregular holes, screws, and gears. We can also manufacture using pure titanium. ■We manufacture all kinds of medical device components. We also produce parts that grasp cells inside the body during surgery. We achieved a tolerance of 0.01 mm for holes using MIM materials, and they were completed without machining. For cutting, we significantly reduced costs for products that are usually very expensive. ■Miniature tool set of about 25 mm using MIM method The lineup of 12 types of mini tools includes "scissors," "needle-nose pliers," "nippers," "pliers," "water pump pliers," "monkey wrench," "c-clamp," "machine vice," "bow saw," "caliper," "micrometer," and "utility knife." All tools are manufactured using the fine molding technology of the MIM method for producing medical device components.

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.
