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" 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. It excels in producing fine thin-walled shapes with thicknesses ranging from 0.2 mm to 5 mm. It can accommodate millimeter orders and demonstrates properties equivalent to those of melted materials, such as torsion and bending. With a density of over 95%, the pores take on a round, independent shape, resulting in excellent mechanical strength. During the binder debinding process, high-speed debinding and sintering are performed to minimize the alteration and deformation of the metal powder. Various conditions such as vacuum, reducing atmosphere, inert atmosphere, and high-pressure atmosphere can be precisely controlled, allowing for sintering processes suitable for each type of metal. There are also examples in medical devices and aerospace components, and it can handle a wide range of production from batches of 10 to tens of thousands. 【Features】 ■ Small lot products of fewer than 3000 pieces are supported with low-cost dedicated molds. ■ In addition to standard metal injection materials, a wide range of materials is accommodated. ■ All processes, including precision machining, heat treatment, and plating, are integrated into a single production line. ■ Quick response to low-cost, short lead times, and design changes or corrections. ■ The entire process from mold creation to machining is managed in-house. *For more details, please refer to the related link page or feel free to contact us.

Solving on-site problems with next-generation casting technology!

"Castings are not suitable for prototyping or small lot production." —Don't you think so? With Castem's "Digital Cast," you can produce casting parts from just one piece without molds by utilizing 3D printing. It offers high freedom of shape and can significantly reduce lead time, costs, and labor. 【Cost Reduction Example】 The part in the thumbnail is a CG manifold that was previously made by machining two parts and then welding them together. Additionally, due to the special material Inconel 625, it was sourced from overseas processing companies, making it a quite high-cost part in the past. However, by creating it as a single molded piece, we achieved a cost reduction of up to 80% and improved strength. "I want to verify shapes that cannot be achieved through machining" and "I want to test with the same material as the final product." We can solve these development challenges with our next-generation precision casting technology, Digital Cast. If you have 3D data, just leave the rest to us. We will provide precision cast products quickly!
