Vacuum ion plating

Vacuum ion plating is in fact one of PVDs that we normally refer to. PVD is the short form of physical vapor deposition and includes three types, vacuum vapor coating, vacuum sputter coating, and vacuum ion coating. However, in the past decade, the technology of vacuum ion coating has developed rapidly and has become one of the most advance surface treatment methods now. Therefore, the PVD plating that we normally talk about is vacuum ion coating.

Manyijin Technology Co., Ltd. currently owns several vacuum devices and production lines that are most advanced and with most reliable performance in the world. All of our machines and auxiliary equipment in our company are supplied by well-known suppliers at home and abroad, and all the devices are equipped with microcomputer control system and professional operating personnel. In terms of color choices, our company provides IP steel, IP gold, IP gun, IP black, IP rose gold, IP brown, IP blue, IP purple, and IP color oxide films. Moreover, we are able to change relevant parameters to adjust the color tone of the coating based on the requirements from customers.

Following is a brief introduction of PVD technology for your reference and further learning:

  • The principle of PVD coating technology- PVD coating (ion coating) technology is to use arc discharge technology of low voltage and strong current under the condition of vacuum to evaporate the target material through gaseous electric discharge and cause ionization on both evaporated substance and gas. The accelerating action of the electric field will deposit the evaporated substance and its reactant on the target material.
  • The features of PVD coating- The coating of PVD technology is with high hardness, high wear resistance (low friction coefficient), very good corrosion resistance, and chemical stability. The coating layer is with more durability and able to hugely increase the appearance decoration performance on the workpiece at the same time.
  • Type of PVD coating- PVD coating technology is an environment-friendly surface treatment method that is able to genuinely obtain micron coating layer without causing any pollution. It is able to fit out various single metal film (such as aluminum, titanium, copper, zirconium, chromium, and gold), nitride film (TiN, ZrN, CrN, and TiAIN), carbon film (TiCN and TiCN), and oxide film (such as TiO).
  • Color choices of PVD coating- The film colors of PVD coating available at the moment are dark gold, light gold, brown, copper, black, grey black, and rainbow color. The finished coating color is usually controlled by the relevant parameters during the coating process. The finished color after coating can be measured by relevant devices to quantify the color in order to ensure the coated color meets the requirement.
  • Difference between PVD coating and traditional galvanic plating- The commonality between PVD coating and traditional galvanic plating is that both are within the scope of surface treatment; both methods cover one material on the surface of another material through a specific method. PVD coating is with great adhesion on the surface of the workpiece, higher film hardness, better abrasion resistance and corrosion resistance, and more stable film performance. PVD coating will not generate toxic and polluted substance; therefore, the coating fully meets RoHS requirements and further satisfies the demand in the international market.
  • Main industries that PVD coating technology currently applies to- The application of PVD coating technology can be divided into two main categories: decorative coating and tool coating. The purpose of decorative coating is primarily to improve the appearance decorative performance and the color of the workpiece providing that no property of the material of the workpiece is changed as well as enhance the abrasion resistance and corrosion resistance on the workpiece at the same time in order to extend its life cycle. The purpose of the tool coating is to increase the hardness and abrasion resistance on the surface of the workpiece as well as reduce the friction coefficient on the surface and further enhance the life cycle of the workpiece. Currently, the main business in our company is the decorative coating and it is used to a wide range of products, including components for clocks and watches, bathroom hardware, building hardware, 3C products, glasses frame, and the accessory of metal jewelry. Meanwhile, Manyijin Technology Co., Ltd. is working hard to develop vacuum functional coating and has developed the first set of large-scale HIPIMS (high power impulse magnetron sputtering) system in Taiwan with dimension of 1500mm x 1800mm.
