Automatic Rotary Drum Spray Coating Machine for Small Parts AJL.R120A -ANGEM
The ANGEM AJL.R120A Automatic Rotary Drum Spray Coating Machine is an independently developed industrial coating system designed for the automated full-surface application of paints and adhesives onto medium and small components.
Developed from ANGEM’s proven R90 series and optimized according to specific customer product characteristics, the AJL.R120A is particularly suitable for ballpoint pen barrels, rubber components, small hardware parts and other products requiring efficient batch coating.
The machine integrates automatic spraying, drum rotation, temperature-controlled drying, exhaust filtration and automatic unloading into one enclosed system. It provides an efficient and environmentally conscious solution for high-volume coating production.
The equipment has been granted Chinese Utility Model Patent Nos. ZL2013 2 0319639.7 and ZL2016 2 0956638.7.
Product Overview
During operation, the workpieces continuously tumble and rotate inside the drum while the automatic spray gun applies paint or adhesive. This tumbling action exposes different surfaces of the parts to the spray, helping achieve more complete and consistent coating coverage.
The spray gun can move vertically and its spraying angle can be adjusted according to the product shape and coating requirements. After spraying, the integrated drying system controls the temperature inside the drum to support coating drying and process stability.
Once the coating cycle is completed, the workpieces are automatically discharged, reducing manual handling and improving production efficiency.

FEATURES
Automatic Full-Surface Coating
Continuous drum rotation causes the workpieces to tumble during spraying, exposing different surfaces and improving overall coating coverage.
Adjustable Spray Gun Position
The spray gun can move up and down automatically. Its spraying angle can also be adjusted according to the product geometry and coating area.
Integrated Drying System
The drying system provides adjustable temperature control from ambient temperature up to 120°C, helping improve drying efficiency and process consistency.
Drum Temperature Monitoring
A temperature sensor continuously monitors the internal drum temperature, supporting safer operation and stable coating conditions.
Fully Enclosed Spraying Process
The enclosed coating chamber helps contain coating mist and exhaust gases, creating a cleaner production environment.
Multi-Stage Exhaust Filtration
The exhaust filtration system collects and filters coating mist and airborne contaminants before discharge. The final configuration can be adapted according to the coating material and local environmental requirements.
Specialized Spray Control System
The integrated spray control system coordinates drum rotation, spray gun movement, spraying time and drying conditions to help achieve consistent surface quality.
Automatic Unloading
After the preset coating and drying cycle is completed, the machine automatically discharges the processed parts, reducing manual handling.
Suitable for High-Volume Production
With a maximum workpiece load of up to 50 kg per batch, the machine is suitable for batch coating of medium and small components.
Reliable Electrical Control
High-quality imported electrical components and a stable control architecture support long-term industrial operation and consistent process performance.
Modern Industrial Design
The machine is manufactured using modern sheet-metal fabrication and precision machining processes. Its powder-coated exterior provides a clean and professional appearance.
APPLICATION FIELD
1. Decorative Coating
Used to apply decorative finishes to small components such as pen barrels, binder clips, wooden toys, hearing aid components, zipper sliders, buttons, fishing hooks, springs and bottle caps. The process helps achieve uniform color and consistent surface appearance.
2. Corrosion-Resistant Coating
Designed for the application of protective coatings to nuts, screws, bolts, small nails, fasteners and other small hardware components. The coating helps improve corrosion resistance and extend product service life.
3. Low-Friction and Lubrication Coating
Suitable for applying water-based lubricant coatings and PTFE low-friction coatings to O-rings and other sealing components. The coating helps reduce friction, improve sliding performance and support smoother assembly and operation.
4. Adhesive Coating
Used to apply bonding adhesives to metal-cased oil seals, metal inserts for automotive shock absorber bushings, brake seals, engine seals and other rubber-to-metal components. It supports consistent adhesive coverage before molding and vulcanization.
5. Electrical Insulation Coating
Suitable for applying electrical insulation coatings to soft magnetic cores, hard magnetic cores, toroidal cores, battery caps and other magnetic or electrical components. The coating helps provide electrical isolation and surface protection.
