Drum Washing Machine
The Drum Type Washing Machine is an industrial-grade cleaning system designed for bulk cleaning of small to medium-sized components. It operates on a rotating perforated drum mechanism, where parts are gently tumbled while undergoing cleaning, rinsing, and drying. This makes it highly efficient for industries handling fasteners, bearings, castings, stampings, and automotive parts that require high-volume, uniform cleaning.
Ralsonics’ Drum Type Washers are engineered to deliver high throughput, low operating cost, and consistent cleaning results, making them a reliable choice for automotive, aerospace, foundries, and general engineering industries.
- Components are loaded into the perforated drum.
- As the drum rotates, the parts are continuously tumbled.
- High-pressure sprays and/or ultrasonic cleaning stages remove oil, grease, dirt, chips, and other contaminants.
- Integrated rinsing and drying modules ensure the parts exit clean and ready for use or further processing.
- The design allows continuous or batch operations, depending on production needs.
- Rotating Drum Mechanism – Ensures all surfaces of the part are exposed during cleaning.
- Continuous Operation – Suitable for high-volume production lines.
- Multi-Stage Cleaning – Cleaning, rinsing, and drying in one compact system.
- Durable Construction – Stainless steel drum and structure for long life.
- Customizable Drum Size – Available in different diameters and lengths for varying part sizes.
- PLC/Digital Control – User-friendly interface with cycle customization.
- Low Maintenance Design – Minimal moving parts for reliable long-term use.
- Integrated Filtration – Recirculation and filtration of cleaning media for cost efficiency.
- High Throughput – Cleans large volumes of parts quickly and efficiently.
- Uniform Cleaning – Tumbling action exposes all part surfaces.
- Space-Saving Design – Compact footprint compared to multi-tank setups.
- Energy & Cost-Efficient – Optimized use of water, detergents, and power.
- Automation Friendly – Can be integrated with conveyors, loaders, and unloaders.
- Safe & Reliable – Enclosed operation with minimal manual intervention.
- Versatile Applications – Suitable for metallic and non-metallic parts.
- Automotive – Cleaning nuts, bolts, bearings, gears, and fasteners.
- Aerospace & Defense – Precision cleaning of small machined components.
- Foundries & Metal Casting – Removal of sand, scale, and oils.
- General Engineering – Cleaning of fabricated or stamped parts.
- Hardware Industry – Washers, screws, and fastener cleaning.
