Electrophoretic Coating - All AOLITE Electric Products Feature Standard

As an innovation leader in the heavy industry sector, AOLITE consistently prioritizes product durability and reliability. We are well aware that, under harsh working conditions, the corrosion resistance of equipment structural components and cover parts (primarily the cab and rear engine hood) directly impacts the machine's service life and operational profitability. Therefore, AOLITE solemnly announces that all structural and cover components across our full range of electric products come standard with an advanced electrophoretic coating process，surpassing industry protection standards and creating lasting value for customers.

What is Electrophoretic Coating?

Electrophoretic coating, also known as electrocoating or e-coating, is an advanced process that uses electrical current to deposit paint uniformly onto conductive workpiece surfaces. This technology provides a solid foundation for exceptional corrosion protection and consistent coating coverage, perfectly adhering even to complex structural parts and components with numerous edges and corners typical in heavy equipment.

Core Steps of AOLITE's Electrophoretic Coating Process

AOLITE Heavy Industry introduces an automated electrocoating line, subjecting every metal component to four rigorous stages:

1. Precision Pretreatment

Components undergo thorough cleaning, degreasing and phosphating. This completely removes oils and contaminants and forms a phosphate conversion coating that enhances both paint adhesion and corrosion resistance, laying the perfect foundation for electrocoating.

2. Comprehensive Electrocoating Immersion

Pretreated workpieces are fully immersed in the electrocoating bath. Under a precisely controlled direct current electric field, charged paint particles deposit evenly across the entire surface, forming a dense, continuous initial coating layer.

3. Efficient Post-Rinse

After exiting the bath, components undergo a cascading rinse with ultrafiltrate and deionized water to recovers poorly adhered paint.. This not only increases paint utilization to over 95%,reflecting AOLITE's commitment to environmental protection, but also ensures an exceptionally clean and smooth coating surface.

4. High-Temperature Curing

The rinsed components enter an oven for curing at a specific temperature. This process cross-links the coating molecules, resulting in a hardened protective layer with superior physical properties (e.g., wear and impact resistance) and chemical resistance (e.g., against corrosion and chemicals).

Why AOLITE Chooses Electrophoretic Coating as Standard?

· All-around Uniform Coverage: The process effectively penetrates inner cavities, narrow gaps, and sharp edges, achieving 360° uniform coating. It eliminates issues like sagging and uncoated areas common with conventional spray painting, providing armor-like protection for AOLITE equipment.

· Superior Corrosion Resistance: The coating is dense and pore-free, acting like protective clothing for the metal substrate. It offers excellent rust and corrosion prevention, significantly extending equipment life in harsh environments like high humidity and salt spray.

· High Efficiency & Automation: AOLITE's automated electrocoating line ensures stable, efficient, and consistent high-volume production. This guarantees that every AOLITE machine delivered possesses the same high-quality, standardized protection.

· Eco-Friendliness & Cost-Effectiveness: With paint utilization exceeding 95%, VOC emissions and material waste are drastically reduced. This aligns with the principles of green manufacturing and helps lower long-term maintenance and lifecycle costs for our customers.

· Excellent Adhesion: The electrophoretic coating bonds firmly to the metal substrate, resisting chipping and peeling. It withstands operational vibrations and impacts, maintaining long-term aesthetic integrity and protective performance.

Making the electrophoretic coating process standard across our entire electric product line is far more than a simple technical upgrade. It is a firm commitment to our core philosophy: "Quality Builds the Future." We are dedicated to continuous improvement in every detail, providing our customers with sturdier, more durable electric products that offer a lower total cost of ownership. Together, let's embrace a new era of green and efficient heavy industry.
