Tumble Spray Coating Systems
The Arnold Machine Tumble Spray Coating System is designed for parts that require 100% surface coverage. Using a controlled tumble-and-spray process inside a fully enclosed, Class 1, Division 1 explosion-proof spray booth, the system applies paint, adhesive, rust preventive, lubricant, or virtually any solvent- or water-based coating material.
Parts are tumbled on a removable mesh belt while being sprayed, ensuring complete and consistent coverage. The system is engineered for maximum transfer efficiency through precise air and fluid process control.
The standard spray chamber measures 16” deep by 40” wide, with batch capacity varying based on part geometry and tumble performance. Each part configuration is programmed using a custom recipe within the integrated touchscreen control system.
Benefits of Tumble Spray Coating Systems
Complete, Consistent Coverage
The tumble and spray application ensures every part is fully coated, making it ideal for parts requiring 100% surface coverage.
High Transfer Efficiency
With precision air and fluid control, the system maximizes coating transfer efficiency, reducing material waste and lowering overall operating costs.
Flexible & Easy to Maintain
The removable tumble belt and customizable recipes on the touchscreen allow quick changeovers, simplified cleaning, and efficient production for a wide range of part sizes and materials.
HOW TUMBLE SPRAY COATING SYSTEMS WORK
The Tumble Spray Coating System uses a controlled tumble-and-spray process designed to ensure complete surface coverage while maximizing coating efficiency:
Loading: Parts are loaded into the spray chamber and placed onto the removable mesh tumble belt.
Tumble & Spray Application: As the belt moves, parts tumble within the 16” deep x 40” wide enclosed chamber. A reciprocating HVLP spray gun applies coating material while the tumbling action exposes all surfaces for consistent, 100% coverage.
Precision Fluid & Air Control: The integrated fluid control system regulates fan, atomize, and pot pressures. Material is supplied from a 5-gallon stainless steel pressure pot with agitation and recirculation to maintain coating consistency throughout the cycle.
Optional Two-Coat Capability: A second spray gun can be added for dual-material or two-coat applications, utilizing the reciprocating shuttle system.
Forced Air Drying: A programmable heating module delivers forced heated air (up to 150°F max air temperature) to assist in coating flash-off and drying.
Unloading: Once the programmed recipe is complete, coated parts exit the chamber, ready for downstream handling or curing processes.
Common Applications
The Tumble Spray Coating System is ideal for manufacturers requiring complete surface coverage on small-to-medium components processed in batch form. The average batch weight is 20–30 lbs and must fit within the 16” deep x 40” wide spray chamber.
Common use cases include:
- High-volume small parts requiring 100% coverage
- Components with complex geometries that benefit from tumble exposure
- Adhesive application before bonding or overmolding
- Metal components requiring rust prevention or lubrication
- Parts requiring consistent, repeatable coating in a controlled, explosion-proof environment
