We will repair metal cracks without applying heat! Metal crack repair! We will mechanically repair the cracks.
【Product PR】 The "MS Method (Mechanical Stitch)" is a revolutionary repair technique (Mechanical Stitch Method) that uses mechanical methods to address cracks in metal. Since it does not apply any heat, there is no "thermal distortion." It prevents the occurrence of residual stress in other areas and also prevents secondary damage such as new cracks. Cracks in metal are one of the concerns in equipment maintenance operations. In conventional 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】 ■ 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 → No significant reduction in equipment operating rates ■ Advantages in safety and environmental aspects → No use of fire, thus no impact on the operating rates of other equipment or the environment For more details, please contact us.

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 delivery times and lower costs. We have extensive experience in various fields, including cast iron cracks, marine 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 the crack to spread, strongly reinforcing 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 that physically repairs metal cracks using special bolts and reinforcement plates (mechanical stitch method), which does not apply heat to the repair area, thus preventing 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 performed on-site, it allows for reduced construction time and cost savings.
