The most common PVD coating process is vacuum evaporation and sputtering coating, ion plating, etc. are called physical vapour deposition.PVD coating has a wide range of applications, from high-precision machining tools, decorative parts, high-demand mechanical parts to various types of moulds and so on, there is a wide range of uses for an environmentally friendly surface treatment method, without affecting the size of the workpiece, the PVD film can be used to improve the appearance of the surface, improve the surface strength, enhanced PVD film can be used to improve surface appearance, surface strength, wear resistance, and has good thermal conductivity, corrosion prevention, and self-lubricating ability without affecting the size of the workpiece.

The potential applications of PVD coatings are expanding, and PVD coatings can be divided into two main categories depending on the application: functional coatings and decorative coatings.

Functional PVD coatings extend the service life and improve the overall performance of a tool or component; thereby reducing the cost of parts in manufacturing. For example, various types of moulds, hobs, cutters, machine parts, etc.

PVD Coatings for Moulds
Decorative PVD depositional coatings improve the appearance of parts with some wear resistance, improved form and function.

Decorative PVD Coating
Wo Sheng Metal has been committed to the improvement of PVD process and coatings.In 2016, Wo Sheng introduced the "Ultra-thick (8μm), ultra-hard (3500Hv or more) PVD coating technology" of Japan's Shinko Group - HKS-G treatment, which is applied to hardware Cold stamping and forming mould insert parts, greatly improving the life of the mould and saving costs for customers.
