Challenge
A manufacturer serving the defense, aerospace, security, and outdoor sports industries needed a reliable solution to clean large volumes of 7.62 mm brass shell casings during production. After leaving the annealing process, the casings required thorough washing to remove contaminants before moving on to final machining. The company needed a system capable of maintaining high throughput while delivering consistent cleaning performance and dependable operation in a demanding manufacturing environment.
Approach
Better Engineering provided a D-24 three-stage drum washer designed for continuous processing of brass shell casings. Parts enter the rotating drum directly from the annealing oven and move through integrated wash, rinse, and drying stages. The drum uses internal scoops to lift and circulate cleaning solutions, fully immersing the casings during the wet stages without the need for pumps. Constructed entirely of stainless steel, the system provides durable operation while ensuring effective solution circulation and consistent exposure of the parts to each stage of the cleaning process.
Results
The drum washer enabled the manufacturer to process brass shell casings at a rate of 30 to 35 pounds per minute, producing approximately 26,000 cleaned shells per hour. The continuous drum design ensures consistent movement of parts through each stage, allowing the system to maintain reliable cleaning performance at high production volumes. This increased throughput improved overall production efficiency while reducing operational costs and maintaining consistent product quality.
Conclusion
The D-24 three-stage drum washer delivered an efficient and dependable solution for cleaning brass shell casings in a high-volume manufacturing environment. Its continuous drum design, integrated cleaning stages, and simple fluid circulation system provide consistent cleaning results while minimizing maintenance requirements. By supporting high throughput and reliable operation, the system helps manufacturers maintain production efficiency while ensuring the quality and precision required in ammunition manufacturing.
