PVD coating technology is widely applied in multiple fields such as aerospace, automotive, tooling, medical devices, electronics, decorative products, and precision instruments. Most PVD-coated components are high-value parts, which require excellent surface performance, durability, wear and corrosion resistance, and aesthetic appeal. During the coating process, contaminants such as oils, greases, residues, dust, oxide films, or fingerprints are prone to remaining on the surface of parts, directly affecting coating adhesion, uniformity, and service life.

In response to different substrate materials, part shapes, and technical requirements, GTK engineers will recommend tailored cleaning and PVD coating solutions for you:

For parts with heavy surface contaminants, spray cleaning systems are required to effectively remove large debris;

For parts with light contamination, solvent or water-based ultrasonic cleaning machines provide thorough cleaning performance;

For parts with deep holes, blind holes, or complex internal channels, basket-rotating ultrasonic cleaning ensures internal surfaces are completely cleaned;

For high-precision or optical components, multi-stage DI water rinsing with bubbling and ultrasonic agitation avoids secondary contamination and ensures no water stains remain;

Air knife and hot air or vacuum drying are used to completely remove residual water, improving coating adhesion and efficiency;

Customized water treatment systems maintain cleaning water quality, extending detergent life and improving overall process stability.

With proper pre-coating cleaning and PVD processing, workpieces achieve high-quality, durable, and visually appealing coatings suitable for demanding industrial and decorative applications.
