Industrial Project Case Study

Project Background & Challenge

A leading European construction machinery manufacturer was experiencing frequent fatigue failures in their excavator arm connectors, leading to costly downtime and warranty claims – a critical issue for their production and operational efficiency.

Our Solution

Our engineering team optimized the material composition to 4140 alloy steel and implemented a vacuum degassing process to eliminate internal porosity. We also adjusted the casting geometry to distribute stress more evenly, aligning with the manufacturer’s industrial performance requirements.

Project Results

The redesigned connectors achieved a 3x increase in service life, reducing the customer's maintenance costs by 65%. We have since become their exclusive supplier for this component, with annual orders exceeding 50,000 units – a testament to our reliability for industrial procurement.
