Many factories face a common dilemma: metal workpieces with qualified base materials and standard processing procedures still suffer from frequent rusting, wear, oxidation and peeling after put into service, resulting in greatly shortened service life. In fact, the poor durability of most metal products stems not from defective base materials, but from substandard metal surface treatment processes. Serving as a protective barrier for metal workpieces, surface treatment directly determines the durability and service life of finished products.

What are the Differences Between Electrostatic Coating and Ordinary Spraying? Which is Better?

Ordinary spraying relies only on air pressure to attach paint mist to workpieces. It can hardly cover dead corners and grooves, leading to uneven coating. Electrostatic coating adopts electrostatic attraction: charged paint mist actively wraps and adheres to grounded workpieces, realizing full coverage without missing spots.

Coating peeling and flaking are common defects for sprayed metal and plastic workpieces, which damage appearance and weaken anti-corrosion performance. Most peeling problems stem from non-standard processing instead of defective coatings, including pretreatment, spraying and curing errors. Targeted solutions can effectively avoid repeated quality failures.

Conventional spraying often causes missing coating, peeling and scratching on hardware and plastic workpieces. As a mature surface coloring technology, electrostatic spraying relies on electrostatic adsorption to realize full-coverage coloring. With standardized pretreatment, it delivers far stronger coating adhesion and durable performance, widely used in mass processing of home appliance parts, chassis shells and plastic structural components.

As a core process for product surface treatment, metal and plastic coating integrates material science and engineering technology. Its core lies in achieving tight bonding between the coating and the substrate through scientific technical means, balancing appearance texture and practical performance, and it is widely used in various fields of industrial manufacturing. Mastering its core technology is the key to ensuring coating quality and enhancing product competitiveness.
