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.

Nitto Kōsaku Co., Ltd. (Osaka) is a comprehensive manufacturing company that supports production through "jig expertise × precision machining." [Reasons Why Jigs Are Necessary | Limitations of Manual Work and Variability in Quality] In the previous discussion, we introduced the basic definition of "jigs." This time, we will explain the background of the necessity for jigs, focusing on the "limitations of manual work," using relatable examples. ☆ When Undertaking the Job of Sharpening Pencils At our company, we explain the concept of "jigs" in an easy-to-understand manner using familiar examples during lectures and presentations. For instance, let's say we take on the job of sharpening pencils from a certain company. If this is done manually with a knife, there will be variations in the angle of sharpening, the length of the lead, and the finished shape depending on the worker. There will also be differences in the time taken to complete the work, leading to challenges in standardizing quality and improving production efficiency. To stabilize "work that is influenced by human skill," jigs are necessary. By using jigs, anyone can process the pencils at the same position and angle, enabling stable production with reduced variability in quality. Our company leverages this concept of jig creation to engage in precision machining, prototype production, and the design and manufacturing of dedicated machines. To be continued.

PiLink Co., Ltd. (Headquarters: Yokohama City, CEO: Kenji Nogata) will start selling two models of its edge AI platform series "PLECO," optimized for industrial applications, on June 1, 2026: the high-performance model "PLECO E5" based on Raspberry Pi 5 (Compute Module 5) and the low-cost model "PLECO E4" based on Raspberry Pi 4 (Compute Module 4).
