In December 2023, a metal processing company in Jiangxi plans to build a new aluminum plate spraying production line to meet the growing market demand and improve product quality.

Customer Needs

The customer hopes that the new coating line can achieve the following goals:

1.Efficient and stable production capacity

2.Excellent coating quality and adhesion

3.Low energy consumption and environmental protection

4.High level of automation, reducing manual intervention

Technical Solution

1. Pretreatment system: including degreasing, pickling, phosphating and other steps. Select efficient pretreatment agents and equipment to ensure that the surface of the aluminum plate is clean and has good coating adhesion. Introduce automated spray pretreatment cleaning equipment and equip it with a temperature control system to maintain stable process conditions.

2. Spraying equipment: Select an efficient electrostatic coating system to improve the conversion rate and adhesion of the coating. An automatic spray gun system can be selected, and a device for adjusting the spraying pressure and angle can be configured. Equipped with an efficient filtration and exhaust system to ensure the cleanliness and safety of the spraying environment.

3. Curing furnace: Select a high-efficiency curing furnace, and use hot air circulation or infrared heating technology to improve the uniformity and efficiency of curing. Configure a temperature control system to accurately control the curing temperature and time. Install an energy recovery device to recover the waste heat in the furnace for heating the pretreatment liquid or auxiliary heating system to reduce energy consumption.

4. Automated conveying system: Design a high-speed and stable conveying chain and roller system, configure sensors and control devices to achieve automated conveying and precise positioning, simplify the conversion of aluminum plates on the production line, and improve production efficiency.

5. Automated control system: Introduce PLC (programmable logic controller) and HMI (human-machine interface) systems to achieve comprehensive automated control of the production line, including process parameter setting, data acquisition and equipment monitoring.

6. Waste gas treatment system: Install efficient waste gas treatment devices, such as activated carbon adsorption and catalytic combustion devices, to treat volatile organic compounds (VOCs) generated during the spraying process.

The carefully designed and implemented new aluminum plate powder coating line not only improves production capacity and coating quality, but also effectively reduces energy consumption and labor costs, bringing significant economic benefits and market competitiveness to the company.
