Vacuum coating machine coating technology industry application
Replacing the traditional electroplating process with vacuum coating technology can not only save a lot of film materials and reduce energy consumption, but also eliminate environmental pollution caused by wet coating. Therefore, foreign countries have adopted vacuum coating process to replace electroplating process in terms of coating anti-corrosion layer and protective film on steel parts.
Why does the evaporation coating machine coat under vacuum conditions If the pressure is not low enough (or the vacuum degree is not high enough), good results cannot be obtained. For example, if aluminum is deposited on the order of 10 2 Torr, the obtained film is not only not bright, but even gray and black. And the mechanical strength is extremely poor.
What is the difference between PVD vacuum coating machine and CVD coating machine? Thin film deposition technology is mainly divided into three major processes: physical, chemical, and epitaxy. Physical vapor deposition is referred to as PVD vacuum coating machine. Chemical vapor deposition is referred to as CVD coating machine for short.
Vacuum conditions in the process of vacuum evaporation coating machine In the vacuum chamber, when the particle concentration in the gas phase and the pressure of the residual gas are low enough, these particles can keep flying in a straight line from the evaporation source to the substrate, otherwise, they will collide and change the direction of motion.
Common problems of PVD evaporation process and sputtering process Vacuum coating equipment uses two common coating processes, evaporation and sputtering. These two processes are currently the most popular and widely used, and their attention is naturally much higher than other processes.
Development and Application of Coating Technology for Ion Plating Equipment Vacuum multi-arc ion coating machine technology Titanium plating is a process for surface treatment of metal materials. It has been widely used in the industrial field and has the intention to gradually promote it.
Advantages of vacuum coating process technology Vacuum coating makes the plastic surface have a metallic texture; because compared with aluminum, copper, iron, stainless steel and other metal parts, the manufacturing process of plastic parts has unique advantages such as large batches, low cost and easy processing.
Encyclopedia of various vacuum pump technologies, a must-read for vacuum coating equipment engineers
A vacuum pump is a device that uses various methods to generate, improve and maintain vacuum in a closed space. A vacuum pump can be defined as a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate the evacuated container to obtain a vacuum.
How does the vacuum coating equipment technology make gradient colors? Standing at the forefront of market and consumer requirements, bold design can be invincible. Vacuum coating equipment processing gradient color can be said to be a popular color this year. Since the Huawei P20 was sold, everyone has confirmed that gradient color has been a design trend in the past two years.
Why use high-purity gas in vacuum coating After high-purity coating metal (such as aluminum) is evaporated at high temperature, it will freely fly away and settle on the surface of the workpiece to form a coating. Argon is a protective gas to prevent the oxidation reaction from affecting the coating quality. In the work of vacuum ion coating equipment, the color of liquid gas will be different when different gases are selected.
Dingyi Technology takes you to understand the composition and structure of the vacuum coating machine With the progress of society, vacuum coating machine technology is also changing with each passing day. Optical coating technology, winding coating technology, decorative coating technology, and magnetron coating technology have already been put into market use in large quantities to meet the current market demand.

How to measure the film thickness of vacuum coating? Many daily necessities are coated with a layer of film by a coating machine, making the product not only more beautiful, but also more practical. But many people have a question, since it is coated with a layer of film, the film must have a thickness, so how thick is the film thickness, and how to measure it?
PVD vacuum ion coating equipment coating processing commonly used targets The biggest difference between the color film layer and the conventional color film layer is the C value and H value, so it can be said that black is also a color film layer.
The vacuum coating machine can be classified according to the function of the vacuum furnace
Vacuum coating equipment is distinguished according to the principle of thin film: it can be divided into sputtering coating, ion coating, evaporation coating and chemical vapor deposition coating. According to the purpose of application, it can be divided into optical coating, winding coating, decorative coating, solar heat collector coating, tool coating, architectural coating, conductive coating and so on. the
What is the difference before and after the workpiece is plated by the vacuum coating machine? Vacuum coating machines are widely used in various industries, including machinery, electronics, hardware, aerospace, medical, chemical and other fields.
Vacuum coating machine design should pay attention to details In order to ensure that the vacuum coating machine has good sealing performance, it is necessary to cut off the cause of possible leaks at the source
How to check for leaks during installation and commissioning of vacuum coating machine The leak detection link of the vacuum coating machine is a step that needs to be carried out in all links from design, manufacture, commissioning, use, etc., and it is absolutely necessary.
Vacuum coating machine sputtering sputtering process introduction The sputtering method can be used to prepare material films with high melting point and low vapor pressure that cannot be prepared by the evaporation process, which is convenient for the preparation of thin films of compounds or alloys. The vacuum coating machine sputtering sputtering process is mainly used for sputtering etching and film deposition. .
Which products can the ion vacuum coating machine be used on? Tableware, kitchen utensils, furniture, toys, and daily decorations that are closely related to our daily life have been coated with a layer of film by an ion vacuum coating machine. This technology and equipment has become an indispensable indirect necessity in our life.
Introduction to basic knowledge of PVD coating of vacuum coating machine PVD (Physical Vapor Deposition) technology is mainly divided into three categories, vacuum evaporation coating, vacuum sputtering coating and vacuum ion coating. Compared with the three classifications of PVD technology, the corresponding vacuum coating equipment also includes vacuum evaporation coating machine, vacuum sputtering coating machine and vacuum ion coating machine.
