Full-Automatic Overhead Conveyor Powder Coating Line with Cyclone Recovery & Curing Tunnel
Full-Automatic Overhead Conveyor Powder Coating Line with Cyclone Recovery & Curing Tunnel
Overview
The CoatTech Full-Automatic Overhead Conveyor Line is a turnkey solution designed for high-efficiency mass production. This closed-loop system seamlessly integrates automated pre-treatment, moisture drying, electrostatic powder application, and high-temperature curing. By automating the transport and coating process, this line significantly reduces labor costs while ensuring a uniform, high-quality finish on every workpiece.
Core Features
-
Continuous Workflow: The QXG-Series suspension chain conveyor runs continuously, enabling high-volume throughput without production bottlenecks.
-
Smart Automation: Controlled by a central PLC touch screen (HMI) with Variable Frequency Drive (VFD) for precise speed adjustments (0-5 m/min).
-
Quick Color Changes: Features a Mono-Cyclone + After-filter recovery system that achieves 98%+ powder recovery and allows color changes in under 15 minutes.
-
Energy Saving Design: The curing oven utilizes an "air return" heating method and high-density rock wool insulation to maximize thermal efficiency.
