PVD (Physical Vapor Deposition) and CVD (Chemical Vapor Deposition) are two major thin-film coating technologies. PVD vaporizes materials through physical means (e.g., heating or sputtering), resulting in strong adhesion but slower deposition rates. CVD forms coatings via chemical reactions, off Read More

For metals, in order to improve the performance of the metal, manufacturers carry out surface treatments to improve the metal. In our daily life, the common metal surface treatment techniques are: pickling and purification treatment, electrolytic polishing treatment, oil and rust removal treatment, Read More

Surface treatment is a process method for forming a surface layer on the surface of a substrate material that differs from the mechanical, physical and chemical properties of the substrate. The purpose of surface treatment is to meet the product's requirements for corrosiSurface treatment is a process method for forming a surface layer on the surface of a substrate material that differs from the mechanical, physical and chemical properties of the substrate. The purpose of surface treatment is to meet the product's requirements for corrosion resistance, wear resistance, decoration or other special functions. The following are common surface treatments.on resistance, wear resistan Read More

PVD coatings are currently available in dark gold, light gold, coffee, bronze, grey, black, grey-black and seven colours. The colour of the coating can be controlled by controlling the relevant parameters during the coating process; the colour can be quantified by measuring the colour with relevant instruments after the coating is completed to determine whether the colour produced meets the requirements.

The production conditions of die casting moulds are the most demanding, with metal solutions at high temperatures of 600-800°C, injection through high pressures and constant thermal expansion and contraction of the mould surface, resulting in a very short service life for die casting moulds, which constantly require mould repair and maintenance during production. The main causes of die casting mould failure are cracking, erosion, sticky material and deformation. Read More

Vacuum coating is a physical vapor deposition process (PVD) in which a metal or metal compound is deposited onto the surface of a material (usually a non-metallic material) in the form of a vapor phase under a vacuum environment. It is also called vacuum metallization because the coating is often a thin metal film. Vacuum coating in a broader sense also includes the vacuum vapor deposition of non-metallic functional films such as polymers on the surface of metallic or non-metallic materials. Read More

 During the PVD vacuum coating process, pressure fluctuations in the coater chamber can lead to uneven coating and poor repeatability. A mass flow controller controls the reaction gas and a pressure controller controls the pressure of the inert gas in the chamber to improve the final plasma vapour deposition (PVD) results.

Specialised physical vapour deposition (PVD) coatings are widely recognised for the key role they play in improving operational performance and extending the life of parts in manufacturing and industry. Read More

Vacuum coating machine in the process of daily use, must be irregular maintenance maintenance, only reasonable maintenance and maintenance, in order to make the vacuum coating machine work, higher efficiency, longer service life, the probability of emergencies is lower, so as to achieve the role of cost reduction.

PVD, like water plating, both belong to the category of surface treatment, and both are used to make one material cover the surface of another material in a certain way to obtain a layer or multiple layers of film with decorative effect or with certain functions (wear resistance, corrosion resistance, heat resistance, electrical conductivity, etc.).

With the development of technology, PVD technology is constantly evolving and many specialised technologies have emerged for certain applications, here is an overview of the various PVD technologies. Read More

Vacuum coating technology did not take long to start and it was only in the 1960s that CVD (Chemical Vapour Deposition) technology was applied to cemented carbide tools internationally. As the technology needs to be carried out at high temperatures, the coating type is single and the limitations are great, therefore, its development is not poor at the beginning. PVD coating technology, on the other hand, has two characteristics: low temperature and high energy, and can be applied to almost any substrate, so it is not surprising that the range of applications is very wide. The development of vacuum coating technology has also seen the emergence of new technologies such as PCVD (physical chemical vapour deposition) and MT-CVD (medium temperature chemical vapour deposition), and a variety of coating equipment and coating processes have emerged, and there is now a pleasing scene of a hundred flowers blossoming in this field.

There are four factors affecting the quality of cleaning, respectively: cleaning time, chemicals, mechanical action and cleaning fluid temperature, the four factors also affect each other, a weakening of factors, can be enhanced through the role of the other three factors to compensate, and vice versa. In these four factors, the cleaning time of the smaller is also the pursuit of the goal, so as to improve the efficiency of cleaning. Shorten the production time and delivery cycle. Read More

The tool is one of the most active elements of the cutting system. With the development of technology, the feed and cutting speeds of coated tools have been increased, while their service life has also been extended. Therefore, in today's rapidly developing machining technology, the performance of tools has gained importance, with coating technology being a key technology in tool manufacture. Read More

PVD coating technology, suitable for injection moulding, hardware, die-casting moulds, parts and cutting tools, has anti-wear and high temperature resistance characteristics, the service life can be increased by 2-10 times, can significantly improve production efficiency and reduce production costs. At present, there are still many mould companies who lack understanding of this technology. Read More
