Single Coat Chain-On-Edge (CoE) Coating System

The Single Coat Chain-On-Edge Coating System automates the coating process, reducing manual labor while ensuring uniform thickness and high-quality results. 

Designed for both high- and low-volume production, it features a rotate & spray application within a Class 1, Division 1 explosion-proof booth for maximum safety and efficiency. 

Its servo motor-controlled chain drive enables continuous or indexed operation, while optimized air and fluid controls enhance repeatability and transfer efficiency.

Precision & Efficiency 

With up to 48 spindles and an HVLP spray gun, the machine ensures consistent, high-quality coating while maximizing throughput.

Explosion-Proof Design

The fully enclosed, NFPA-rated air capture spray booth prevents solvent-laden air from escaping, while integrated fire suppression and safety interlocks protect operators.

Reliable, Low-Maintenance Operation

Features like automatic chain tensioning, a central lubrication point, and a filter change alert minimize downtime and simplify maintenance.

How Single Coat Chain-on-Edge Coating Systems Work

The Single Coat Chain-on-Edge System is a compact and efficient coating solution designed to transport parts through a structured series of stations. Each station is crucial in ensuring a precise and consistent coating application. The system is engineered to apply a single coating material (either solvent- or water-based) throughout the process, offering a robust and reliable solution.

  1.     Parts are manually loaded into the fixture and conveyed to the spray booth either in an indexing motion or constant speed. The parts will be conveyed through the oven if the optional heating module is included.
  2.     The chain moves to the coating booth, where a mechanism rotates the spindle and part for the spray cycle.
  3. A single HVLP spray gun applies coating in either the standard fixed mounted position, single-axis servo-positioned, or robotic-positioned.
  4. The coated part moves throughout the coating booth and back to the operator for removal. The parts will again be conveyed through the oven if the optional heating module is included.

Common Applications

Chain-on-Edge (CoE) conveyors are specifically designed for coating straight or profiled cylindrical substrates that require inside or outside diameter coverage. These systems efficiently coat multiple surfaces of a part in a single pass, making them highly effective for various industrial applications.

The Single-Coat Chain-On-Edge Conveyor is optimized for high & low-volume production where repeatability and efficiency are critical. It is commonly used in automotive, industrial, and consumer goods manufacturing to apply rust preventive, adhesive, or lubricant coatings.

Ideal Substrates & Part Specifications:

  • Suitable for aluminum, steel, or plastic components.
  • Designed for parts ranging from 1 to 5 inches in diameter and up to 6 inches in height.
  • Well-suited for consistent part sizes and shapes in both small and large production runs.

While CoE systems offer high efficiency and precision, it's essential to consider part size limitations and variations when selecting this coating solution to ensure optimal performance.
