CASTEM Co., Ltd. will exhibit at the SPEXA International Space Business Expo.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repairs without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

We will be exhibiting at the "3rd SPEXA International Space Business Exhibition" held at Tokyo Big Sight from May 27 (Wednesday) to May 29 (Friday), 2026. At this exhibition, we will introduce our precision casting and MIM (Metal Injection Molding) technologies, which cater to high-performance and difficult-to-machine materials such as A7075 super duralumin, Inconel, and titanium. "We want to reduce material costs." "We want to lower the machining costs of difficult-to-machine materials." "We are looking for a manufacturer for small quantity parts." In response to these challenges, Castem offers component manufacturing solutions utilizing casting and MIM technologies. We can accommodate everything from small-scale prototypes to small-lot repeat production. Please feel free to consult with us at the venue. 【Exhibition Overview】 Exhibition: 3rd SPEXA International Space Business Exhibition Dates: May 27 (Wednesday) to May 29 (Friday), 2026, 10:00 AM to 5:00 PM Venue: Tokyo Big Sight, South Exhibition Hall S6-2 (3-11-1 Ariake, Koto-ku, Tokyo) URL: https://www.spexa.jp/tokyo/ja-jp.html
