Tableware PVD coating machine (usually using PVD physical vapor deposition technology) is becoming increasingly important in the field of tableware manufacturing.

It provides an environmentally friendly, durable and beautiful surface treatment solution, especially suitable for high-end tableware and tableware products requiring special properties.

Features:

Diversified film layers
Features:

Can deposit a variety of functional film layers:
Decorative:

Titanium nitride (TiN - gold), titanium carbonitride (TiCN - rose gold), zirconium nitride (ZrN - imitation gold/champagne gold), chromium nitride (CrN - bright silver/stainless steel color), diamond-like carbon (DLC - black/gray black), titanium oxide (TiO₂ - color/interference color), pure metal (such as chromium Cr), etc. Rich colors and strong metallic luster.

Create high value-added appearance:

Provide a long-lasting and luxurious decorative effect.

Functionality:

Titanium nitride, chromium nitride, diamond-like carbon, etc. have extremely high hardness and wear resistance; chromium, DLC, etc. have excellent corrosion resistance; some film layers (such as TiO₂) have certain antibacterial or photocatalytic self-cleaning properties.

Advantages:

It meets the dual demands of tableware for beauty (color, gloss) and performance (wear resistance, corrosion resistance, easy cleaning, antibacterial).

Excellent film properties

High hardness:

Many PVD film layers are much harder than stainless steel substrates, significantly improving the surface's scratch and wear resistance.

Strong bonding:

In a vacuum environment, the film atoms are tightly bonded to the substrate atoms, with strong bonding and not easy to peel off.

Excellent corrosion resistance:

The dense film layer can effectively isolate the corrosion of corrosive media such as water, acid, alkali, and salt on the substrate. Especially the chromium-based film layer.

Good chemical stability:

The inert film layer is not easy to react chemically with food and has high safety.

Thin and uniform thickness:

The film layer thickness is usually in the micron level, evenly covering complex surfaces (such as the grooves of knives and forks, the curved surface of spoons), without affecting the original fineness of the tableware.

High process controllability

Features:

Precisely control parameters such as vacuum, temperature, gas flow, sputtering power, time, etc.

Advantages:

The color, thickness, structure, and performance of the film layer can be precisely controlled to ensure the consistency and stability of product quality between batches. Easy to achieve automation and mass production.

Environmental protection and safety
Features:

As mentioned above, no harmful chemical emissions. The film layer itself usually meets the safety standards for food contact materials.

Advantages:

Comply with increasingly stringent environmental regulations, the production process is safe, and the end product is safe for the human body.
