UNIQUE POLYMER SYSTEMS is dedicated to providing cutting-edge repair solutions for industrial machinery. This case study details the successful restoration of keyways on a large diameter shaft in a steel mill using our UPS 105 EG THISTLEBOND METAL REPAIR PASTE.

In a high-demand steel mill environment, keyways on a large diameter shaft had become stripped over time due to age and excessive torque. This wear compromised the shaft's performance and threatened the overall efficiency of the mill's operations.

The critical challenge was to restore the keyways effectively and swiftly, minimising downtime and ensuring the repaired shaft could withstand the operational demands of the steel mill.

UNIQUE POLYMER SYSTEMS recommended using our UPS 105 EG, a high-performance product specifically designed for metal repairs. This paste provides excellent adhesion and durability, making it ideal for rebuilding worn components.

Preparation: The shaft was thoroughly cleaned using a solvent to remove any contaminats. A release agent (UPS Release Agent) was applied to areas that were not intended for bonding.

Surface Preparation: Handheld grinders were used to remove any loose steel sections and to create a coarse profile on the surface of the key seat. This step ensured optimal adhesion of UPS 105 EG.

Application of UPS 105 EG THISTLEBOND METAL REPAIR PASTE: 

- UPS 105 EG was applied to fill the voids in the keyway area.

- The shaft was then carefully inserted into the key seat, ensuring a precise fit.

- Excess material was removed, and the assembly was allowed to cure, forming a strong and durable bond.

The repair process successfully restored the keyways to their original condition, allowing the shaft to function as intended. This efficient solution minimised downtime and maintained the operational efficiency of the steel mill.

This case study demonstrates the effectiveness of UPS 105 EG THISTLEBOND METAL REPAIR PASTE in restoring worn keyways in industrial settings. Our high-quality repair solution provided a durable and reliable fix, ensuring long-term performance and operational continuity.
