【Product PR】 The "MS Method (Mechanical Stitch)" is a revolutionary repair technique (Mechanical Stitch Method) that addresses metal cracks using mechanical methods. Since no heat is applied at all, there is no "thermal distortion." Residual stress in other areas does not occur, preventing secondary damage such as new cracks. Metal cracks are one of the concerns in equipment maintenance operations. In typical 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 from heat ■ Elimination of secondary damage ■ Maintenance of stable quality → Integrated system repairs using jigs, etc. → Accumulation of know-how, experience, and achievements ■ Completion of work 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.

【Basic Information】 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 carried out on-site, it allows for reduced lead times and cost savings. We have experience in a wide range of fields, including cast iron cracks, marine equipment, power generation facilities, and cement equipment. Please feel free to contact us if you have any questions. 【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 expand, strongly reinforcing the base material ○ MS Bolt Hole Repair Insert → Female-threaded 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.
