Shortening construction period, metal crack repair, metal crack restoration, equipment maintenance, thread regeneration.
Repair metal cracks without applying heat! There’s no need to worry about using fire on-site or damaging the base material with welding heat!
The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitch Method) that employs mechanical methods to address cracks in metal. Since it does not apply any heat, there is no "thermal distortion." Residual stress in other areas does not occur, preventing secondary damage such as new cracks. Cracks in metal are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods cause changes in the base material around the crack 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 track record - Completion of construction in a short period → Does not significantly reduce the operating rate of equipment - Advantages in safety and environmental aspects → No use of fire, thus no impact on the operating rate of other equipment or the environment For more details, please contact us.

Damaged Bolt Hole Repair Insert "MS Insert" The "MS Insert" is a female thread part designed to repair damaged bolt holes. It embeds an insert with a special structure applied to the outer diameter thread section into the bolt hole area for regeneration. It is difficult to pull out and does not put stress on the base material, making it suitable for installation in areas constantly exposed to vibration or at the ends. Compared to conventional products such as spring-type coils and self-tapping items, it improves precision and demonstrates groundbreaking effects in terms of durability.

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.
