In the automotive industry, ensuring continuous production and maintaining equipment reliability are vital for meeting both quality expectations and delivery schedules. Radiator manufacturing relies heavily on core builder machines, which are responsible for assembling radiator cores with precision and consistency. Any unplanned downtime in these machines can significantly disrupt the manufacturing process, leading to production delays, increased operational costs, and potential risks to product quality.

A common challenge encountered with core builder machines is the frequent failure of their motion systems, particularly those exposed to high cycle rates and harsh working environments. For example, in one case, a belt-driven servo piston system used in a core builder machine was found to fail approximately every two months. These failures resulted in notable unplanned downtime, impacting overall production efficiency and placing additional strain on maintenance teams.

To address this issue, a practical maintenance improvement was implemented by replacing the original belt-driven servo piston system with a pneumatic piston solution. This modification aimed to enhance the reliability of the machine, reduce the frequency of unexpected breakdowns, and improve maintenance efficiency. After the change, operational data and maintenance records were reviewed to evaluate the impact on machine performance. The observations revealed that the pneumatic piston system performed more consistently under demanding conditions, leading to fewer failures, reduced downtime, and lower maintenance costs.

Overall, this study demonstrates that targeted maintenance improvements can have a positive impact on equipment reliability and production continuity in radiator manufacturing.
