With PVD (Physical Vapor Deposition) technology, plastic parts can be given a high-quality metallic look - glossy or matt, and in many different colors. In addition to the added aesthetic value, metallization also improves the functionality and durability of the components. It protects against scratches and abrasion, maintains color intensity and enables additional properties such as light or radar transmission. PVD technology therefore meets the highest requirements in industries such as automotive, sanitary ware, household appliances, consumer electronics, luxury jewelry and medical technology.
How are polymers metallized?
The impact of accelerated argon ions causes free metal ions of the source metal to be emitted from the target. By applying a uniform or pulsed DC voltage to the components (substrates) and simultaneously supplying the process gases, a thin layer of a metal-gas compound is deposited on the plastic surface using the sputtering process. Up to three process gases can be used simultaneously during a metallization process.
The PVD process takes place in a vacuum chamber and at a maximum temperature of 80 °C. For an evenly distributed coating, the plastic parts are rotated around several axes at a constant speed.
Process gases that can be used: argon, nitrogen, acetylene, optionally also carbon dioxide or other process gases.
Recommended metals for sputtering targets: Chromium, titanium, zirconium, aluminum, tungsten, molybdenum, stainless steel, copper, silver, gold (optional) and many other non-ferromagnetic metals.
Suitable substrate materials: ABS*, PC*, PC/ABS*, PC/PBT*, PC/PET*, selected PA compounds (glass fibre or mineral fibre reinforced), galvanized plastics, electroless nickel-plated plastic parts, painted substrates and also glass.
