Autonomous Concrete Mold Lubrication System

Precision Robotics in Concrete Manufacturing

The manual application of concrete release oil at the JK Lakshmi Cement facility was a significant operational challenge. Traditionally, workers applied the lubricant using a brush, a process that was slow and highly inconsistent. This manual method typically consumed between 1.4L and 1.5L of oil per mold and took several minutes to complete. Because human application is inherently variable, the resulting coatings were often uneven, which could impact the final surface quality of the concrete products.

To solve this, we implemented an automated cell featuring a Yaskawa GP25 robot equipped with a high-precision spray nozzle. This system is designed to deliver a perfectly uniform layer of oil across every mold with mathematical accuracy. By digitizing the spray path, the robot eliminates the patchy results of manual labor, ensuring that every mold is prepared to the highest industrial standard without the risk of human error or material buildup.

The transition to robotics has delivered a dramatic leap in production efficiency. What once took minutes is now achieved in a blistering 13 seconds per mold. Furthermore, the precision of the Yaskawa GP25 has optimized material usage, slashing oil consumption to just 700ml per cycle. This 50% reduction in waste, combined with the rapid cycle time, provides a highly cost-effective and sustainable solution that allows the facility to maximize its output while maintaining superior product quality.
