Mechanical stitch method (crack repair)
Not welding! A new method for repairing metal cracks! Prevents damage and recurrence of cracks without adding heat. Permanent solution for metal fractures in aluminum castings.
Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs often change the base material around the crack due to heat, leading to residual stress and deformation, which constantly 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 carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

basic information
The metal crack repair using the MS method 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 executed on-site, it allows for reduced lead times and lower costs. 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 would cause 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

Company information
The mechanical stitch metal crack repair technology is a method (mechanical stitch method) that physically repairs metal cracks using special bolts and reinforcement plates, and since it does not apply heat to the repair area, it does not cause thermal distortion in the crack repair (mechanical stitch method). In addition to metal crack repair, it also has the technology to regenerate damaged screw threads using repair inserts. Furthermore, since repairs can be conducted on-site, it allows for reduced construction time and cost savings.
