PVD Coatings for Writing Instruments: Durable, Chrome Free and Luxurious Finishes

The Manufacturing Challenge

In premium writing instruments, surface finish defines the first impression of quality and craftsmanship.
For decades, electroplating was the standard, but it now presents increasing problems including color fading, corrosion, and inconsistent gloss that weaken brand image and reduce product lifespan.

With strict global restrictions on hexavalent chrome (Cr VI) and rising expectations for sustainable manufacturing, traditional plating is no longer a long term solution.
Manufacturers now need a coating process that provides durability, visual consistency, and compliance while preserving design elegance and production efficiency.

The Modern Solution: Industrial Grade PVD Coatings

NTI Nanofilm provides advanced PVD and taC coating solutions developed to replace conventional plating.
Our proprietary Filtered Cathodic Vacuum Arc (FCVA) and Hybrid PVD CVD technologies deliver a cleaner, stronger, and highly repeatable coating process proven in large scale pen production.

Each coating is validated by real production data to ensure stability across metal and plastic components including caps, clips, barrels, and nibs.

Technical Performance at a Glance

Parameter	Specification	Key Benefit for Writing Instruments
Hardness	Up to 5000 HV	Maintains long lasting wear and scratch resistance
Corrosion Resistance	More than 96 hours salt spray (ASTM B117)	Prevents tarnishing and pitting from moisture and oxidation
Surface Smoothness	Ra < 0.1 µm	Delivers a smooth premium tactile feel
Laser Engraving	Fully compatible	Produces sharp logos and text with no peeling
Color Consistency	CIELAB ΔE < 1.0	Ensures uniform color tone across gold, silver, black, and custom finishes
Dual Color Capability	Two tones on one component	Enables refined gold and black or silver and champagne combinations

All specifications are verified under production conditions for reliable repeatability.
