Can brass CNC machining turning parts be PVD?

Many people don't know what PVD is, so our VMT engineers compiled the knowledge of brass CNC machining turning parts PVD to let everyone know about PVD. First of all, PVD we often say refers to physical vapor deposition, which uses physical processes to transfer, transfer the source to the surface of the brass custom CNC machining turned parts material, spray specific particles (high strength, wear resistance, performance, performance), corrosion resistance, etc.) to increase the material Surface characteristics.

Brass CNC machining turning parts PVD (Physical Vapor Deposition) technology is divided into three categories: vacuum evaporation coating, vacuum sputtering coating and vacuum ion coating. Compared with the three major types of PVD technology, the corresponding vacuum coating equipment includes vacuum evaporation coating machine, vacuum sputtering coating machine and vacuum ion coating machine. In the past ten years, vacuum ion plating technology has developed the fastest and has become one of the most advanced surface treatment methods. What we usually call brass CNC machining turning parts PVD coating refers to vacuum ion coating; the commonly referred to PVD coating machine refers to vacuum ion coating machine.


The application of brass CNC machining turning parts PVD coating technology is mainly divided into two categories: decorative plating and tool plating.


Mainly used in various fields of the hardware industry, such as brass CNC machining turning parts, door and window hardware, locks, bathroom hardware and other industries.

The purpose of tool plating is to improve the surface hardness and wear resistance of the brass CNC machining turning parts, reduce the friction coefficient of the surface, and increase the service life of the workpiece;



Mainly used for various brass CNC machining turning parts tools (such as turning tools, planers, milling cutters, drills, etc.) and other products. It is an environmentally friendly surface treatment method that can truly obtain micron-level pollution-free coatings. Various single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (TiN [titanium gold], ZrN (zirconium gold), CrN, TiAlN) and carbide films (TiC, TiCN) can be prepared, and Oxide film (such as TiO, etc.). It is a very cost-effective surface treatment method, so PVD technology has developed rapidly in recent years.


Brass CNC machining turning parts adopts PVD coating technology to coat the film with high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, etc., and the film has a longer life; at the same time, the film can Greatly improve the appearance and decorative performance of the workpiece.



Material application PVD film can be directly plated on stainless steel and cemented carbide、Brass CNC machining turning parts, but for zinc alloy, copper, iron and other die-casting parts, it is advisable to conduct chemical chromium plating before PVD plating. PVD can be plated with gold, brass, rose gold, silver white, black, smoky gray, copper, brown, purple, blue, wine red, bronze and other colors, and can provide the required color and quality.



Of course, in the production process, we are more concerned about the Brass CNC machining turning parts price issue. Although the use of PVD coating technology can produce high-quality coatings, the cost of the PVD coating process is actually not high. If the appearance requirements are Brass turning parts relatively high, sandblasting should be carried out before electroplating. According to the appearance grade, select the appropriate sand type, and cover the defects such as knives, bumps and scratches caused by the previous process with sand to achieve the lowest cost. Products that meet the requirements.



The above is the knowledge points of Brass CNC machining turning parts PVD. VMT has many friends with strong PVD technology who have cooperated for more than ten years. They can quickly cooperate with the production of color samples and rapid mass production delivery. For more detailed information, please contact VMT precision metal parts machining manufacturer.
