PVD plating quality technology is considered a big step forward in the field of plating. PVD plating significantly improves the plating layer, creating products with a shiny, attractive appearance and high durability. However, to ensure that PVD-coated products are always of the best quality, many different factors must be considered. The materials used and the size of the galvanizing furnace are considered two of the five factors that determine the quality of PVD plating.

Materials used to process PVD-coated products
Materials used to process PVD plating products can be metal, plastic, glass, ceramic, etc. Among them, stainless steel is the leading material used to apply PVD plating on metal.
Plating stainless steel – a material that resists rust and corrosion well – will create PVD-plated products with long-term durability and high aesthetics.
Although there are many types of stainless steel, PVD coating only improves durability and rust resistance. The grade of stainless steel used is still the deciding factor. Stainless steel 304, despite its higher price, is still the top choice because of its excellent rust resistance and good machinability.
Prepare the product before the PVD plating process
Before proceeding with PVD plating, product preparation is very important. If the materials used can affect the durability of the product, the processing process before plating will have an impact on the beauty of the plating layer after completion.
PVD coating only has a thickness ranging from 0.5 to 10 microns, so it cannot completely cover defects on the surface of the material. This requires meticulous machining and surface treatment before entering the plating process.
Surface treatment of stainless steel before plating will improve adhesion, creating a uniform, smooth plating layer that is difficult to peel off.
Depending on the customer’s specific requirements, units carry out processes such as polishing, creating scratches or blurring the surface before plating to ensure the most optimal aesthetics.
Dimensions of the galvanizing furnace during the plating process
The size of the plating furnace during the plating process plays an important role in the quality of PVD plating products.
The plating furnace needs to have the appropriate size for each type of product to ensure the plating layer has the best quality and aesthetics.
For large sized products, plating needs to be done in a furnace of appropriate size to avoid unevenness in the plating layer. Currently, Nam Viet CNC is the owner of a galvanizing furnace with a size of 4m high and 2m in diameter, the largest scale plating workshop in Hanoi.
Processing process before PVD plating
Before proceeding with PVD plating, the processing process will affect the beauty of the final product. PVD coating thickness ranges from 0.5-10um, so it cannot completely cover defects on the surface of the material.
Therefore, treating the stainless steel surface before plating will increase adhesion, creating a uniform, smooth and non-peeling plating layer.
This process depends on the customer’s specific requirements and may include polishing, scratching or blurring the surface to ensure the highest aesthetics.
The PVD plating process plays an important role in determining the quality of the plating layer, including adhesion, wear resistance, hardness and color uniformity.
All of these factors depend on technology, equipment and engineer operations.
Currently, the PVD plating process is automated through machines, reducing human intervention.
However, the galvanist still plays an important role in setting and monitoring process parameters. Therefore, the plating team needs to clearly understand how to operate the galvanizing furnace and adjust appropriate parameters to create a plating layer with the desired color.
Currently, the PVD plating process is often automated by machines, reducing human intervention in the production process.
However, the plating technician still plays an important role in setting up the process and monitoring the parameters.
Therefore, the plating team needs to clearly understand how the galvanizing furnace works and be able to adjust the parameters accordingly, to create a plating layer with the desired color and quality.
