At UNIQUE POLYMER SYSTEMS, we specialise in providing advanced repair solutions for industrial machinery. This case study outlines 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 busy steel mill, the keyways on a large diameter shaft had become stripped over time due to age and excessive torque. This degradation compromised the functionality and safety of the equipment, necessitating an effective repair solution.

The primary challenge was to restore the keyways to their original specifications without causing prolonged downtime, which could disrupt the mill’s operations and productivity.

UNIQUE POLYMER SYSTEMS proposed using our UPS 105 EG. This product is ideal for rebuilding and repairing metal components, offering superior adhesion and durability.

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

Surface Preparation: Handheld grinders were utilised to remove any loose steel sections and to prepare the surface of the key seat, creating a coarse profile that would enhance the adhesion of the repair paste.

Application of UPS 105 EG THISTLEBOND METAL REPAIR PASTE:

- UPS 105 EG was applied to 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 quick and efficient solution minimised downtime and maintained the operational efficiency of the steel mill.

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