Repair methods for screw threads, cast iron prototypes, 3D printing, casting crack repair.
We will restore aluminum, cast iron, and cast steel damaged female threads, bolt holes, and broken female threads to their original size.
"MS Insert" is a female screw part designed to repair damaged bolt holes. An insert that applies a special structure to the outer diameter screw thread is embedded in the bolt hole area for regeneration. It is difficult to pull out and does not impose a load on the base material, making it suitable for areas that are constantly exposed to vibrations or for end sections. Compared to conventional products such as spring-type coils and self-tapping items, it improves precision and demonstrates groundbreaking effects in terms of durability. Additionally, by applying it in areas where bolts are frequently removed and attached, permanent measures can be implemented. 【Features】 ■ Difficult to pull out and does not impose a load on the base material ■ Ideal for permanent measures for screw holes ■ Can be used to reinforce and recover screw threads ■ Enables application to end sections → Designed with upward-facing screw threads that attract the surrounding base material towards the center of the screw from all directions For more details, please contact us or download the catalog.

Company information
The mechanical stitch metal crack repair technology is a method (mechanical stitch method) that physically repairs metal cracks using special bolts and reinforcement plates, and since it does not apply heat to the repair area, it does not cause 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 conducted on-site, it allows for reduced construction time and cost savings.
