Non-heat mechanical crack repair, metal crack repair, casting repair, cast iron.
Not welding! A new method for repairing metal cracks! Prevents damage and reoccurrence of cracks without adding heat. Permanent solution for metal fractures in aluminum castings.
Metal cracks are one of the concerns in equipment maintenance. 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 reoccurrence" and "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 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.
basic information
The MS method for repairing metal cracks demonstrates outstanding effectiveness in terms of precision, durability, and cost compared to conventional methods. It is a technology that physically repairs cracks using our special bolts and reinforcement plates. Since it can be implemented on-site, it allows for reduced lead times and cost savings. We have experience in a wide range of fields, including cast iron cracks, ship equipment, power generation facilities, and cement equipment. Please feel free to contact us if you have any questions. 【Product Lineup】 ○ S-Bolt → Ensures airtightness and crack removal → Thoughtfully designed screw structure achieves tensile strength of the base material ○ T-Bolt → Prevents MS reinforcement plate from pulling out and patch repairs → Unique tapered section enhances airtightness and prevents loosening ○ MS Reinforcement Plate → Reinforces and restores the repair area → Suppresses the force that causes cracks to spread and strongly reinforces the base material ○ MS Bolt Hole Repair Insert → Female thread part for reinforcing damaged bolt holes ・ HS Type Insert: For cases where there are no cracks around the bolt hole ・ HF Type Insert: For cases where there are cracks around the bolt hole

Detailed information
-
Mechanical Stitching Method (Crack Repair) The Mechanical Stitching Method is an innovative crack repair technique that does not apply heat, thus preventing hardening and residual stress, and also preventing secondary damage.
-
MS Insert Kit (Bolt Hole Repair) The MS Insert is a female thread part used to repair damaged bolt holes. Due to its specially structured outer diameter thread, it is difficult to pull out and does not put stress on the base material.
