Notice of Participation in the Kanto Mechanical Components Technology Exhibition [Leave it to us for precision metal parts!]

High-level quality developed independently! Compatible with over 70 types of steel, with more than 35,000 proven models. We propose the optimal shape and material according to your application.

Castem's core technology is "lost wax precision casting," which excels in producing complex three-dimensional shapes. Since our founding, we have continued to respond to customer inquiries for manufacturing everything from simple shapes to challenging designs, with a track record of over 35,000 types of precision metal parts across various industrial sectors. In response to various demands for metal materials, we have started handling over 70 types of steel, including stainless steel, copper, and aluminum. We also accommodate special steels and unique ultra-duralumin aluminum materials (A7075 optimized for original casting), and we continue to challenge ourselves with new materials. 【Castem's Lost Wax】 - Capable of mass-producing complex shapes and three-dimensional curved surfaces at low cost. - There are slight differences depending on the casting material (approximately 12S for small parts, 20S for large parts). - Strength can be freely pursued from two aspects: shape and material. - Special steel, stainless steel, copper alloys, and aluminum alloys can be freely selected. - Compared to other casting methods, it offers high precision and reduces the number of processing steps. *For more details, please refer to the related link page or feel free to contact us.

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!

In public construction civil engineering sites, there are many instances where sheets are used as common temporary facilities, such as construction roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates were common, but due to their weight, transportation and installation can be cumbersome. Hyper CLT sheets are civil engineering materials made from wooden CLT for civil engineering use. The 5×10 sheet weighs about 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to transport, install, and remove, even with small machinery. They can be widely utilized for temporary roads, heavy machinery scaffolding, pathways within the site, and protection of material storage in public works. Since they are made of wood, they also contribute to environmental aspects such as reducing summer heat reflection, lowering noise, and fixing CO2. They can simultaneously address construction efficiency, safety measures, and environmental considerations, making them effective for innovative proposals in public works. Furthermore, they improve transportation efficiency and reduce labor in site operations as an alternative to steel plates. Hyper CLT sheets are registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A." They are recommended for companies considering civil engineering, civil engineering use, and civil engineering CLT. Feel free to request materials or consult about implementation. They are temporary materials that also help improve site evaluations in public works. Please consider them.

We have released a new video on our company’s YouTube channel. The theme of this video is "The World of Amino Acid-Based Shampoos." Amino acid-based shampoos have become popular in recent years, but the lather, feel, and finish can vary greatly depending on the cleansing ingredients used. In this video, we clearly explain the changes in user experience based on the differences in cleansing ingredients by comparing two types of amino acid-based shampoos. We hope you can use this as a hint for developing original shampoos and differentiation.

New York and Tokyo, June 26, 2026 - (JCN Newswire) - This year's successful listing of PayPay Corporation (hereinafter "PayPay") on NASDAQ has provided a significant boost. The question now facing Japan's leading innovation companies is no longer "Is a U.S. listing feasible?" but rather "How can we attract global capital and build companies that align with global growth strategies?" The 2nd Japan Go IPO Summit will be held on September 16, 2026, at the Grand Hyatt Tokyo to address this question. This summit is hosted by MarcumAsia and organized by AUM Advisors.

Our company representative, Shibata, will be speaking as a lecturer at the "Mikata Project" AI Utilization Seminar for the automotive industry, hosted by the Chubu Bureau of Economy, Trade and Industry. ■ Title: AI Implementation Course Leading to Results - Learning Success Patterns and Practical Processes from Real Examples in Manufacturing Sites "We implemented AI, but it is not being used on-site and is left unattended" and "The implementation has become the goal without yielding results" - we have seen many such stumbling blocks in manufacturing sites. In the seminar, based on real examples, we will discuss common patterns for successful implementation that lead to results, pitfalls to avoid, and practical processes to ensure AI is continuously used. We will also propose specific measures for sites struggling with technology transfer and dependency on individuals. ■ Event Overview Date: July 3, 2026 (Friday) 13:30 - 16:00 Venue: TKP Meitetsu Nagoya Station Conference Center + Online Participation Fee: Free / Application Deadline: June 30 (Tuesday) Organizer: Chubu Bureau of Economy, Trade and Industry (Automotive Industry "Mikata Project") Co-presenter: Satoru Hayami, Waseda University For details and registration, please visit the official page of the Chubu Bureau of Economy, Trade and Industry.
