A Physical Vapor Deposition (PVD) coating machine is an industrial system used to apply thin, durable coatings onto various substrates. This process occurs within a high-vacuum chamber, where a solid material, known as the target, is vaporized. The vapor then condenses onto the surface of the workpiece, forming a thin film. Common PVD techniques include sputtering and evaporation.

These machines are vital in numerous industries due to the superior properties of PVD coatings. The resulting films are exceptionally hard, wear-resistant, and corrosion-resistant. They also provide excellent aesthetic qualities with a uniform, consistent finish. A key advantage is that these coatings do not alter the precise dimensions of the underlying part, making them ideal for components with tight tolerances.
