In general, the use of materials on behalf configured well, the natural life will be longer, the efficiency will be higher, film better.

Second, the vacuum coating machine housing: If the surface, basically difficult to see is good or bad, not only from the surface gives the visual effect to distinguish the case basically every vacuum equipment manufacturers can be processed out. For the case should focus on sealing, welding is very important, if you buy back the equipment found to have leakage problems that customers will be very headache, even indirectly, some inexplicable problems, causes leak occur often because processing not good. Therefore, customers choose to buy vacuum coating machine / coating equipment when we must focus on processing power.

Third, the core technology: the different processes used in the core is not the same, unified call evaporation source, but it is a target head or electronic guns. If you do not have good evaporation source, basically not try to complete the stable quality of the coating. Good evaporation source is needed after years of constantly improve and perfect coating of data and then come out, do not understand the process of evaporation source manufacturers difficult to do. If what manufacturers say that their equipment does not include the process, some do not buy it.

Fourth, field trips, samples proofing: Before you buy or coating equipment vacuum coating machine, take samples to coating, check the film coating system is not able to reach their own requirements, its technical service and after-sales service is not perfect, combined with the above mentioned consulting Consulting more points, the last shop around

Vacuum coating equipment ABS plastic plating common process

Vacuum coating equipment ABS plastic plating process can be divided into three parts, this is the pre-treatment process, chemical plating and electroplating processes. Each section contains a number of processes or procedures.
(1) vacuum coating equipment ABS plastic plating pretreatment process for pre-treatment process, including surface finishing, stress checks, degreasing and coarsen...ing.

① surface finishing. ABS plastics before the treatment, to be a surface finishing, this is because in the plastic injection molding process there will be residual stress. Special gates and a portion corresponding to the gate, there will be the internal stress.

② the stress screening method. At room temperature injection molded ABS plastic release acetic immersed 2 ~ 3min, then carefully cleaned surface, dry.
③ degreasing. You can have a lot of choice in addition to oil business, after degreasing, first wash in hot water, then wash in water, and then in a 5% sulfuric acid neutralization, and then cleaned before entering the roughing process, so you can protection roughening solution so life is extended.

④ coarsening. ABS plastic roughening methods there are three types, namely high acid, high chromic acid and phosphoric acid type, from the point of view of environmental protection, it should adopt the high sulfate type.
(2) vacuum coating machine ABS plastic plating process plating process includes sensitization, activation, electroless copper or nickel plating
3) vacuum coating machine ABS plastic plating process is divided into thick plating, decorative and functional electroplating plating three.
① vacuum coating equipment thicker plating. Due to the chemical coating is very thin, make metalized plastic achieve the effect, the coating must have a certain thickness, so to thicken after plating plating.
② vacuum coating equipment decorative plating decorative plating can be a copper-nickel-chromium process, it can be bright copper then other finishing, such as brushing bronze after treatment, it can be bright nickel plated copper after adding in the light, then plated imitation gold.
③ vacuum coating equipment functional electroplating. Functional functional purpose actually depends mainly on the nature of the surface electroplated coating to be embodied. In fact, from a broad perspective, also a decorative function, but the function mentioned here, or physical or chemical means, or electrical properties. For example the conductive coating, reflective coatings, electromagnetic shielding coating, welding coating and the like.

Analysis Principle vacuum coating equipment

Principle is the principle of magnetron sputtering vacuum coating equipment , as follows:
Colliding electrons accelerated in the electric field toward the substrate during in and argon atoms, a large number of ionized argon ions and electrons, the electrons onto the substrate. Argon ions accelerated in the electric field bombardment target, a large number of target atoms sputtered, neutral target atoms... deposited in a film on the substrate.
Secondary electrons accelerated toward the substrate in the process influenced by the magnetic force of the magnetic field Lorenzi, bound within plasma region near the target surface, a high plasma density region, under the effect of the secondary electrons around the magnetic field the target surface in a circular motion, the motion path of the electrons is very long, constantly in motion the process of collision ionization of argon atoms with a large amount of argon ion bombardment target, after several collisions electron energy decreases, get rid of the shackles of the magnetic field lines , away from the target, eventually deposited on the substrate.
Magnetron sputtering is bound to a magnetic field and to extend the path of movement of electrons, the electrons change the direction of motion, increase the ionization rate of the working gas and the efficient use of energy of the electron vacuum coating apparatus.
Electronic destination just substrates, the vacuum chamber wall and the target source anode is electronic home. But generally the vacuum chamber and the substrate and the anode potential in the same. Interaction between magnetic field and electric field so that a single spiral electron trajectory in three dimensions, and not only in a circular motion in the target surface. As for the type of the target surface sputtering the circumferential contour, and that the magnetic field lines are targets of the circumferential shape of circular. Distribution of magnetic field lines in different directions will film a great relationship.
Coating machine manufacturers said, not only in the interaction mechanism magnetron sputtering magnetic and electric fields of work, multi-arc plated target ion source, a plasma source and so work under this principle. The difference is that the electric field direction, voltage and current magnitude only.

Car paint coating merchants to introduce the benefits of the coating

Application of coating on the eyes, coating are commonly used in the camera lens, such as myopia, hyperopia, presbyopic glasses corrective lenses.
Coating is very thin, transparent film on the surface plating. The purpose is to wish to reduce the reflection of light, increase light transmittance, anti-ultraviolet radiation and minimizing down, ghost; Different colors of coating, also make different imaging color balance. In addition, the coating can be delay aging lens, color changing time.
Application in automobile, coating and beauty is the highest measures of protection of paint, can avoid oxidation, to brighten up to the paint, acid and alkali resistance, oxidation resistance, resistance to ultraviolet radiation, such as multiple functions. Because itself is a kind of inorganic membrane materials, no damage to paint.
In to the car coating, the color of its body due to aging embrittlement of paint and corrosion formation of oxide layer will go away for years. Can increase the surface hardness, avoid scratches and small aperture. Hold time is longest, about more than a year.
Coating is not perfect, the brightness is inferior to seal glair when finished plating membrane, therefore is not suitable for love beautiful juyou, vehicle coating price in one thousand yuan of above.
The principle of coating, the coating is mainly in order to reduce the reflection. In order to improve the light transmittance of lens and the quality of the image, in the modern lens to the lens coating manufacturing process. Lens coating is according to the principle of optical interference, on the lens surface plating layer thickness of about a quarter wavelength of the material (usually a fluoride), make the lens to the wavelength of light reflection to a minimum. Obviously, a membrane only work on a light, and multi-layer coating can work on a variety of colours. Multilayer coating with different materials usually repeatedly on lens surface plating layer with different thickness. Multilayer coating can greatly improve the light transmittance of the lens, for example, without coating on the surface of the lens every reflectivity of 5%, after the single layer coating down to 2%, and the multi-layer coating can be down to 0.2%, in this way, can greatly reduce the diffuse reflection between each camera lens, so as to improve the contrast of image and Octavia degrees.

The influencing factors on the quality of the vacuum coating machine coating

Should often clean vacuum chamber, vacuum environment to maintain the health: vacuum health health is first cavity gas. The cavity gas should have enough purity and stability. The second is cavity body health. Cavity should keep the corresponding cleanliness. There can be no dust, waste metal scraps. Because of the metal vapour and gas ionization can make cavity adhesion dirt, should keep clear of in time. Otherwise, accumulate over a long period will be more difficult to remove. Only guarantee the vacuum health can guarantee the quality of coating.
The stability of the gas flow: only the stable flow to maintain the stability of cavity environment, to ensure stable temperature, the thermal stress in the film by uniform stability, ensure effective membrane adhesion strength.
The stability of the vacuum, vacuum degree to produce a great impact on the various types of production process. The coating process is no exception. Such as material in vacuum, the boiling point is lower than in the atmosphere, under the condition of vacuum can lower the temperature of the material needed for a large amount of evaporation, and in the vacuum coating interior coating material can be evaporated at lower temperatures. Corresponding less oxygen in low vacuum area, the possibility of oxidation was greatly decreases, and vacuum coating can get high purity has the practical value of the coating layer. So the stability of the vacuum degree can effectively guarantee the experiment parameters, ensure the quality of coating.
Circulating water cooling in time (mainly pump can work properly) : an effective cooling circulating water is also a stable experimental conditions and the experimental parameters. The main equipment is pump. So in determining the water tank filled with water under the premise of enough to ensure the normal work of the pump.
