This is a record of repairing cracks in a press machine frame! It is possible to repair cracks without applying any heat! Crack repairs that do not cause any distortion at all.
【Product PR】 The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitching Method) that addresses metal cracks using mechanical methods. Since it does not apply any heat, it does not cause "thermal distortion." There is no residual stress in other areas, 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 track record ■ Completion of construction in a short period → Significantly does not 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.

basic information
【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 performed on-site, it allows for reduced lead times and cost savings. We have experience in a wide range of fields, including cast iron cracks, ship equipment, power generation facilities, and cement equipment. Please feel free to contact us if you have any questions. 【Lineup】 ○ S Bolt → Ensures airtightness and removes cracks → 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 spread and strongly reinforces the base material ○ MS Bolt Hole Repair Insert → Female threaded part for reinforcing damaged bolt holes ・HS Type Insert: When there are no cracks around the bolt hole ・HF Type Insert: When 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.
