Dingfeng Automation 4.3m Mesh-Plate Tunnel Oven 15-Lane High-Density Design for Cellcon CMC Assembly Line

Dongguan Dingfeng Automation Equipment Co., Ltd. has successfully delivered a 4.3m mesh-plate tunnel oven (DF-HK1000-4.3M)  to Shenzhen Hymson Laser Intelligent Equipment Co., Ltd. The oven will be used for precision drying in the Cellcon B955 CMC assembly line. From design review to in-house testing, the project took 30 working days and is now entering on-site installation.

📋 Project Background: High Density, High Takt, High Consistency

The Cellcon B955 CMC assembly line required a drying solution for products measuring 370×40×60mm, weighing 2KG, with a capacity of 1000pcs/h. Baking time: ~30 min (10 min ramp + 20 min hold). Cooling time: 7 min, final temperature 50±5°C. To meet high takt and multi-lane parallel processing, Dingfeng Automation proposed a 15-lane mesh-plate conveyor solution.

🏗️ 15-Lane High-Density Design – Maximum Throughput per Line

15 lanes run simultaneously, each independently guided. Positioning pins on each mesh plate ensure accurate fixture placement – no shifting or collision. Fixture presence sensors at infeed (per lane) and arrival sensors at outfeed (per lane) provide real-time tracking.

⚙️ Servo Drive + Mitsubishi PLC + Delta Temperature Control – Precision and Stability

The oven uses a servo motor + planetary reducer drive with torque overload protection. Speed range: 0.1–0.2 m/min, stepless adjustable. The control system is built around a Mitsubishi PLC (FX3U-64MT/ES-A) with Delta temperature modules (DTN4RTCC) and SCR thyristor output, achieving ±0.5°C control accuracy.

- Heating Zone: 1 zone, 2300mm length

- Temperature Range: RT~150°C (typical 90–100°C)

- Uniformity: ≤±10°C (full-load steady-state)

- Heating: Hot air circulation + medium-wave IR auxiliary lamps (6 at infeed)

- Circulation Fan: 750W long-shaft motor + 9-inch multi-blade impeller

Each zone has 12 external temperature probes, positioned 20–30mm above products. Output terminals are grouped on the operation panel for easy spot-checking without opening the oven. Each heating tube includes current monitoring with automatic alarm on abnormality.

🛡️ Safety & Maintenance – Details That Matter

Built for 24-hour continuous operation, modular sections for easy maintenance.

📊 Energy Performance: 26KW Rated, 11KW/h at Steady State

🤝 Service Commitment: Fast Response, Long-Term Support

- Warranty: 12 months from acceptance, free repairs (excluding consumables and misuse)

- Response: Within 30 minutes; on-site within 2–3 hours in Guangdong, 48 hours outside

- Spare Parts: One set of consumables on-site; critical parts available for 24-hour emergency dispatch

- Acceptance: 1 month continuous full-load operation without major issues; noise ≤65dB; vibration ≤1mm

🏭 Application Value

This tunnel oven is custom-built for the Cellcon CMC assembly line. The 15-lane high-density design maximizes floor space, while servo drive and Mitsubishi PLC ensure long-term stable operation. The equipment has been delivered to Hymson and will soon be commissioned at Cellcon B955 CMC assembly line.
