Metal fatigue cracks, hydraulic press crack repair, damage, loss, screw hole repair method.

Metal crack repair without applying heat! Crack repair that generates no thermal distortion at all! Screw hole repair!

The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitch Method) that addresses metal cracks using mechanical methods. Since it does not apply any heat, there is no "thermal distortion." It prevents residual stress from occurring in other areas and also prevents secondary damage such as new cracks. Metal cracks are one of the concerns in equipment maintenance operations. In general welding repair methods, the base material around the crack changes due to heat, leading to residual stress and distortion, which always carries the risk of "crack recurrence" and "secondary damage." **Features of the MS Method** - No hardening or residual stress due to heat - Elimination of secondary damage - Maintenance of stable quality → Integrated system repairs using jigs, etc. → Accumulation of know-how, experience, and achievements - Completion of construction in a short period → Does not significantly reduce the operating rate of equipment - Advantages in safety and environmental aspects → Since no fire is used, there is no impact on the operating rate of other equipment or the environment For more details, please contact us.

Cast steel, cast iron, aluminum, casting, repair, bolt hole repair.

Not welding! A new method for repairing metal cracks! Prevents damage and recurrence of cracks without adding heat - permanent solution for metal fractures.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods 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 Water Supply 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 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.

Anchor Bolt "R Anchor" 【※High Safety!】

Since it is removed after use, it does not negatively impact the concrete and is safe! It prevents foreign objects from remaining in the concrete and falling off.

The "R Anchor" is a post-installed anchor bolt that can be removed after use, such as for temporary materials. It has a special coating on the embedded part of the anchor bolt, allowing it to be extracted by applying reverse rotation with a wrench after use. Since iron expands when it rusts, if it remains as a foreign object in concrete, there is a risk that the concrete may spall. Our product can be removed, ensuring high safety without adversely affecting the concrete. 【Features】 ■ The bolt can be extracted by rotating it in reverse. ■ No need for concrete chipping or cutting of the anchor bolt during removal. ■ Noise reduction. ■ Can be installed at low temperatures (minimum usable temperature -10°C). ■□ For detailed information, please contact the manufacturer of the R Anchor, Sanpo Co., Ltd.! □■ *For more details, please refer to the catalog or feel free to contact us.

Anchor bolts that can be removed after use, contributing to the SDGs.

Introduction of the post-installed anchor bolt "R Anchor" that can be extracted after use! *Technical materials available.

<This is an anchor bolt that can be completely removed without chipping concrete.> It can be extracted by rotating the bolt counterclockwise with strong force after use. There is no need to chip the concrete during removal, so no concrete debris is generated. This helps reduce industrial waste and contributes to the SDGs goal "12. Responsible consumption and production." <It contributes to improving the durability of concrete.> There is no need to cut the anchor bolt during removal. Since no cut pieces of the anchor bolt remain inside the concrete, the factors causing deterioration are eliminated, leading to improved durability of the concrete. 【Features】 ■ The bolt can be extracted by rotating it counterclockwise. ■ No need for concrete chipping work or cutting of the anchor bolt during removal. ■ Noise reduction. ■ Can be installed at low temperatures (minimum usable temperature -10°C). *For details, please contact us or refer to the catalog. We recommend reading it alongside the "R Anchor" and "NR Anchor" catalogs.
