A new method for metal crack repair that shortens construction time, reduces costs, and does not apply heat! No thermal distortion since no heat is applied!
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 residual stress in other areas and also prevents secondary damage such as new cracks! In general welding repair methods, heat causes changes in the base material around the crack, 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.

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.
