Two Coat Chain-On-Edge (CoE) Coating System
The Two Coat Chain-On-Edge Coating System is designed for fast, precise, and consistent multi-layer coating, ideal for demanding, high-volume production.
It features a rotate-and-spray mechanism within a fully enclosed explosion-proof booth for safety and compliance. A servo-driven chain conveyor provides continuous or indexed part movement, and advanced control systems enable repeatable results.

Engineered for Customization
This solution can be engineered to fit your unique coating process—including options for multiple guns, custom fixturing, robotic positioning, and additional drying or curing zones.
How Two Coat CoE Coating Systems Work
Arnold Machine Chain-on-Edge cleaning lines streamline the coating process by transporting parts through a series of zones designed for loading, pre-heating, spray application, drying, and cooling. We designed the system to utilize and apply one of 2 coating materials at any time throughout the process – solvent or water-based adhesive primer and top coat.
Here’s a detailed look at how they work:
- Load Zone: It is the operator’s responsibility to manually load the appropriate fixtures and parts onto the spindles presented in the load area. This area will have 6' of accessible fixtures for loading and also contains an overhead light for easy visualization. The load zone includes an operator work fan.
- Pre-Heat Zone: In order for the primer to adhere to the part it needs to be pre-heated to a predetermined temperature. The pre-heat zone in the oven consists of forty-eight (48) spindles to maximize cycle time and oven efficiency. Once the parts have reached temperature in the pre-heat zone, they will convey to the primer spray zone.
- First Spray Zone: Parts will enter the spray booth and the spindle will be engaged with a variable speed belt drive system for part rotation. Two (2) Krautzberger spray guns mounted to FANUC Paint Mate robots are utilized to apply the primer to the part. The Spray zone is designed to control air flow for maximum transfer efficiency and to accommodate ease of clean up and maintenance. Between the first spray zone and the first dry oven, a Keyence flow sensor will be utilized to verify a specific amount of primer has been sprayed from the spray gun, if primer flow is not detected, top coat will not be applied to the part in the top coat zone. The primer pressure pot will be located in the material storage cabinet and will be provided with all gun connections to the pot.
- First Coat Dry Zone: After parts exit the first spray zone, they will enter back into the oven for a series of cycles in the first dry zone. This area will allow for additional dry time of the first before the top coat is applied. There will be eight (8) spindles in this zone.
- Second Spray Zone: Parts enter the second coat spray zone from the first dry zone and the spindle will be engaged with a variable speed belt drive system for part rotation. Two (2) Krautzberger spray guns will be utilized to apply the second coat to the part. The guns will be fixed mounted to a FANUC Paint Mate robot. This spray zone will be designed to control air flow for maximum transfer efficiency and to accommodate ease of clean up and maintenance. The second coat pressure pot will be located in the material storage cabinet and will be provided with all gun connections for the pot. Along with first spray zone, the second coat zone will also utilize Keyence flow sensors. If second coat flow is not detected, the machine will send an alarm to the operator for part inspection and removal.
- Second Coat Dry Zone: After parts exit the second coat spray zone, they then enter the second coat dry zone. This zone consists of fifty-two (52) spindles that allow the final coat to fully dry before being handled by an operator. Once the part is fully dry it will enter the cooling zone in order for the part to decrease temperature for operator manual unload.
- Cooling Zone: Parts exiting the top coat dry oven will enter the cooling zone. Parts will exit the cooling zone and be presented to the operator for unloading. The operator is responsible for performing a visual inspection of the coating quality and placement into the appropriate customer supplied container before loading the next part and continuing the cycle over. An operator light will be provided in this zone for ease of visualization and product review.
Common Applications
Chain-on-edge conveyors are commonly used to coat straight or profiled cylindrical substrates that require inside or outside diameter coverage.
They efficiently coat multiple faces of a part when needed. Typically, they are used with aluminum or steel substrates ranging in diameter from 1 inch to 5 inches and up to 8 inches tall.
Our CoE conveyors are ideal for large production runs with consistent part sizes and shapes. These systems automate the painting process and reduce the need for manual involvement.
This leads to excellent process control and ensures each part is painted similarly. However, it is important to consider part size limitations and variations when choosing this system.
