There are also examples of medical device parts and aerospace-related parts. We can accommodate a wide range from lots of 10 pieces to tens of thousands!
The "Metal Injection Molding" process is a manufacturing method that creates metal parts in the desired shape by mixing powdered metal with a binder and injecting it into a mold. It excels in producing fine thin-walled shapes with thicknesses ranging from 0.2 mm to 5 mm. It accommodates millimeter-scale orders and demonstrates properties equivalent to those of wrought materials, such as torsion and bending. 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 speeds to minimize the alteration and deformation of the metal powder, allowing for sintering under various conditions, including vacuum, reducing atmosphere, inert atmosphere, and high-pressure atmosphere, tailored to each metal's requirements. There are also examples in medical devices and aerospace components, with a wide range of production from batches of 10 to tens of thousands. **Features** - Small lot products of fewer than 3000 pieces are handled with low-cost dedicated molds. - In addition to standard metal injection materials, a wide range of materials is supported. - All processes, including precision machining, heat treatment, and plating, are integrated. - Quick response to low-cost, short lead times, and design changes. - The process is developed in-house. *For more details, please refer to the related link page or feel free to contact us.*

■Machined Products → Cost Reduction and Improved Lead Time with MIM Method Previously, we used machined products, but by switching to manufacturing with the MIM (Metal Injection Molding) method, we have improved mass production capabilities and lead times. Additionally, we are reducing material weight to achieve cost reductions as much as possible. ■Manufacturing All Types of Medical Device Parts The imaging product is a 5mm long component used during surgery to grasp cells inside the body, produced using the MIM method. The holes achieve a tolerance of 0.01mm with MIM material, and it was completed without machining. We were able to significantly reduce costs for products that are very expensive to produce through machining. 【Flow Until Delivery】 ■1. Design ■2. Mold Production ■3. Injection Molding ■4.

■We manufacture all types of medical device components. The image product is a 5mm long component made using the MIM method, designed to grasp cells within the body during surgery. The hole achieves a tolerance of 0.01mm with MIM material, and it was completed without machining. With cutting, we were able to significantly reduce costs for a product that would otherwise be very expensive.
-
A miniature tool set of approximately 25mm is also produced using the MIM method. The lineup of 12 types of mini tools includes "scissors," "needle-nose pliers," "nippers," "pliers," "water pump pliers," "monkey wrench," "shackle wrench," "machine vice," "bow saw," "caliper," "micrometer," and "utility knife." All tools are manufactured using the fine molding technology of the MIM method, which is used to create parts for medical devices.

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.
