Characteristics of vacuum coating processing
Features of vacuum coating processing. Vacuum coating is an important aspect of vacuum applications. Vacuum coating processing is based on vacuum technology and uses physical or chemical methods. It incorporates a series of new technologies, including electron beams, molecular beams, ion beams, plasma beams, radio frequency, and magnetron sputtering.

Principle analysis of PVD coating machine
The size of a PVD coating machine varies depending on the requirements of the processed product. Currently, most vacuum chambers have diameters of 0.9M, 1.3M, 1.5M, 1.8M, etc. The chamber is made of stainless steel, requiring it to be rust-free and sturdy. Each part of the PVD coating machine has a connecting valve for connecting to the pump.

Introduction to the basic knowledge of PVD coating machine coating
Films deposited using PVD coating machine technology are characterized by high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and a longer service life. At the same time, the film layer can greatly improve the appearance and decorative performance of the workpiece.

Why is it necessary to clean the PVD coating machine?
Before using the coating material in the PVD coating machine, a simple surface cleaning of the coating material can prolong the service life of the coating machine. This is because various contaminants not only prevent the vacuum system from achieving the required vacuum degree, but also affect the strength and sealing performance of the vacuum components.

How to maintain the return oil of a PVD coating machine?
If the vacuum gauge is not damaged, it is generally not necessary to repair the return oil. It is mainly used to clean the oil in the diffusion pump of the PVD coating machine vacuum chamber. Wipe all walls of the vacuum chamber with gasoline, and then wipe it again with alcohol. The key is to clean the oil stains. If there is oil stains in the chamber, the coating will appear white, and the paint film quality will be poor. This is not because of the damage of the electroplating equipment, but because of the oil in the vacuum chamber.

Pvd coating machine coating technology process steps and principles
In terms of ion plating, the evaporated material particles have a kinetic energy of 3000~5000 electron volts after ionization. High-speed bombardment of the workpiece not only accelerates the deposition speed, but the PVD coating machine can also penetrate the workpiece surface, injecting into the substrate to form a very deep diffusion layer. The interface diffusion depth of ion plating can reach 4~5 micrometers.

Introduction to the coating principle of PVD coating machine
The coated workpiece of the PVD coating machine is processed in a vacuum chamber. Physical vapor deposition (PVD) coating technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating, and vacuum ion coating. The vacuum coating machines corresponding to the three classifications of PVD coating machine technology include vacuum evaporation coating machines, vacuum sputtering coating machines, and vacuum ion plating machines. In recent decades, vacuum ion plating technology has developed rapidly and has become one of the most advanced surface treatment methods today. The PVD coating we often talk about refers to vacuum ion coating. Let's learn about the PVD coating machine coating principle!

What are the steps in the PVD coating process?
Before the PVD coating process, the machine requires color removal, spraying, polishing, passivation, cleaning, and clamping. Coating process, vacuum extraction, heating and baking, leak testing, bombardment cleaning, coating, and post-cooling process: First, the cleaning process ensures the cleanliness of the product surface before PVD coating. The fresher the surface, the better the coating quality.

Pre- and post-treatment methods for vacuum PVD coating machines
Vacuum PVD coating machines are currently widely used vacuum equipment for manufacturing under vacuum conditions. They generally utilize three working principles: vacuum chamber, vacuum unit, and electrical control cabinet.

PVD coating machine manufacturer tells you maintenance secrets
When using a PVD coating machine, after completing more than 200 coating processes, the equipment must be cleaned with a saturated sodium hydroxide (NaOH) solution. The inner walls of the vacuum chamber should be repeatedly scrubbed with a saturated sodium hydroxide (NaOH) solution. (Note: Human skin should not come into direct contact with caustic soda solution to avoid burns.) The purpose is to allow the coated aluminum (Al) to react with NaOH. After the reaction, the film will peel off and release hydrogen gas.
