Greenheck’s Advanced HMI System: The Key to Streamlined and Automated Operations
Greenheck has implemented a highly efficient HMI (Human-Machine Interface) system to streamline its production process, ensuring ease of use and accessibility for all team members without extensive training. The system is designed to optimize the paint carrier strategy, ensuring seamless movement of products through the manufacturing stages.
The process begins at the loading station, where production orders are entered and loaded onto the paint line based on a recipe system. The products then move through a five-stage auto wash system, which removes dust, grease, and grime, leaving only bare metal. Following this, the products pass through a dry-off oven, reaching temperatures of 150-175°F to eliminate any remaining oils and chemicals.
The next stage involves painting, starting with the robotic paint booth, powered by FANUC robots and a Norton paint system. Approximately 95% of the painting process is automated, with the remaining 5% completed manually for touch-ups. After quality checks, the products enter the cure oven, which reaches 375-400°F for a 35-minute cure cycle, followed by a 10-15 minute cooldown.
For products requiring a two-coat process, an interloop system allows for an additional gel oven treatment, creating a tacky texture before the second coat is applied. Once the final coating is cured, the products move to unloading and assembly, completing a highly streamlined and automated process that enhances efficiency and quality.
