We provide metallic, titanium-like, and custom-tinted finishes such as chrome, black, gold, and gunmetal, ensuring realistic production-intent appearance for automotive design reviews and branding validation.

Strong Adhesion & Durability

Our vacuum deposition process ensures strong atomic-level bonding, achieving excellent scratch resistance and long-term color stability even under frequent handling in automotive prototype evaluation environments.

Overview

More About PVD Coating

Pros and Cons of PVD Coating

/01

Pros
PVD coating offers exceptional surface hardness, premium metallic appearance, and excellent wear resistance, making it ideal for automotive prototypes requiring high-end interior aesthetics and durable surface performance.

Cons
However, the process requires vacuum chamber processing, which limits part size, may involve higher production costs compared to conventional coatings, and is primarily suitable for conductive or metal-compatible substrates.

Technical Parameters of PVD Coating

/02

Our PVD coating process for automotive prototypes is controlled through vacuum deposition conditions, target materials, and plasma parameters to ensure precise film formation.

We regulate chamber vacuum level, substrate temperature, deposition rate, and ion energy to achieve consistent thin-film quality across complex automotive prototype geometries.

Process control includes surface cleaning, ion etching pre-treatment, coating deposition cycles, cooling stabilization, and inspection stages to ensure uniform color, adhesion strength, and surface hardness for automotive design validation.
