Cast iron, SUS, aluminum, cast steel crack repair, screw hole repair, aluminum screw hole.
We will repair damage (cracks) that occurred in machinery and equipment using mechanical methods without applying heat.
The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitch Method) that uses mechanical means to address cracks in metal. Unlike welding repairs that involve thermal curing, this method does not apply any heat, thus preventing "thermal distortion." It does not generate residual stress in other areas, thereby preventing secondary damage such as new cracks. 【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 track record ■ 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.
