Bolt hole restoration
We will repair the crushed female threads of the platen and die plate, bolt holes, and damaged female threads to their original size.
【Product PR】 The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitching Method) that addresses metal cracks using a mechanical approach. Since no heat is applied at all, there is no "thermal distortion." Residual stress in other areas does not occur, preventing secondary damage such as new cracks. Metal cracks are one of the concerns in equipment maintenance. In typical welding repair methods, heat alters 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 from heat ■ Elimination of secondary damage ■ Maintenance of stable quality → Integrated system repairs using jigs, etc. → Accumulation of know-how, experience, and achievements ■ Completion of work 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
【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 construction can be performed on-site, it allows for reduced lead times and lower costs. We have experience in a wide range of fields including cast iron cracks, marine 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, strongly reinforcing the base material ○ MS Bolt Hole Repair Insert → Female threaded 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
