At Guanghe, we specialize in engineering continuous conveyor systems that synchronize pretreatment, spraying, and curing into one seamless flow. If you are planning a high-capacity wheel line, here is what you need to know about tunnel ovens.
1. Designed for Continuous Flow
Unlike a batch oven, a tunnel oven allows wheels to move constantly on an overhead conveyor system.
- The Advantage: No manual pushing of heavy racks. Wheels transition from the spray booth directly into the heated tunnel, ensuring that every rim spends the exact same amount of time at the required curing temperature.
2. Key Dimensions: It’s All About the "Line Speed"
- Calculation: If your powder requires 15 minutes to cure at 200°C, and your conveyor moves at 2 meters per minute, your tunnel oven needs to be at least 30 meters long to ensure a full cure.
- Guanghe Customization: We design the tunnel length and width based on your specific output goals, whether it’s 500 wheels or 2,000 wheels per shift.
3. Energy Efficiency: The "Bridge-Type" Design
- How it works: The entrance and exit are located at the bottom, while the heated section is elevated. Since heat rises, this "air seal" prevents precious thermal energy from escaping, reducing fuel or electricity consumption by up to 30%.
4. Precision Temperature Control for Aluminum
5. Integration with Automatic Spray Booths
A Guanghe tunnel oven is most effective when paired with our Quick Color Change Big Cyclone Booth. The automated reciprocators spray the wheels as they move past, and the tunnel oven cures them immediately, reducing the risk of dust contamination.
Investing in an automated tunnel line from Guanghe is about more than just speed—it’s about lowering the cost per part while maintaining "OEM-level" quality.
