The trend of modern mechanical industry leads to higher and higher requirements for mechanical parts: reducing friction and increasing the efficiency of the workpiece, strengthening the load force and reliability of the workpiece, reducing the damage to the environment and reducing the use of lubricants. These trends make the pressure of the contact surface of the workpiece increase greatly, the heavier load, and the reduction of lubricant accelerate the wear of the workpiece surface.

With the rise of made in China, any minor process improvement may mean the improvement of competitiveness for enterprises. PVD coating can also play its excellent performance in many key parts, such as the application of piston and crankshaft, reducing friction force, improving wear resistance and meeting the requirements of oil-free lubrication and service life with its low friction coefficient.

The PVD coating on the piston and crankshaft of the automobile instead of the original electroplating hard chromium treatment not only avoids the problem of polluting the environment, but also significantly improves the surface hardness and wear resistance of the workpiece, and the service life is increased by more than 10 times. At the same time, because of the reduction of the friction coefficient of the surface film layer, the noise generated during the operation of the component decreases.

For China's booming automobile industry, the country has put forward higher and higher requirements for energy conservation, emission reduction and manufacturing technology. PVD vacuum coating can be used for surface treatment and production of auto parts, replacing or partially replacing traditional chemical plating. It provides "near zero emission" key basic equipment and complete coating production line solutions for auto parts enterprises, so as to realize automobile Green manufacturing of parts surface treatment.

HCVAC uses innovative material system and related patent coating technology to develop coating with high bonding force, high temperature resistance and wear resistance, and combines the coating technology with HCVAC PVD coating equipment to improve the surface performance of key components in many industries. The effect is to solve the problems of high temperature wear resistance, oxidation resistance, lubrication and service life Significantly improved. Under the comprehensive test conditions, HCVAC coating technology and coating equipment performance indicators are in the leading level in China, and has large-scale production capacity.
