Various working principle of Vacuum coating equipments

Various working principle of Vacuum coating equipments

Vacuum coating equipments can be divided into: evaporation vacuum coating equipments, magnetron sputtering vacuum coating equipments and ion plating vacuum coating equipments.
Evaporation vacuum coating machine working principle is to put the coating materials into the vacuum chamber,heating to evaporate the evaporation source, when the mean free path of molecules is greater than the linear dimensions of the evaporation vacuum coating chamber, atomic and molecular vapor escaping from the surface of the evaporation source, little impact and impede other molecules or atoms, can be plated directly to the surface of the substrate, due to the low temperature of the substrate, and then condense on film.
Magnetron Sputtering vacuum coating machine is formed by a vacuum glow discharge, accelerate the positive ions bombard the target so that the sputtering phenomenon caused by the surface, so that the target surface deposition of particles emitted onto the substrate to form a film.
Multi-arc ion vacuum plating machine is the use of a vacuum arc discharge evaporation source count for technology that ignited the evaporation source (cathode) in a vacuum environment, between the anode and the formation of a self-sustaining arc discharge, both cathode material released from the cathode arc shining point ions. Since the current local concentration, the Joule heat generated by the cathode material locally explosively into plasma, under the influence of operating bias of a compound with the reaction gas, and the deposition is formed on the surface plated layer.

Vacuum coating equipment ABS plastic plating common process

       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 coarsening.

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.

Vacuum Coaters wet coating technology and coating technology

      Vacuum Coaters wet coating technology and coating technology

Membrane extensive selection of vacuum coating technology, you can control the thickness of the film and coating system functionality and performance of different films, can make a lot of new material with chemical and physical properties.
Wet coating technology is way past a coating that plating or electroplating, chemical reduction of the principles applied in the material deposited, this method will produce waste polluting the environment, in the past a lot of plating plant because of pollution problems have changed the coating process .
Vacuum coating system film coating technology, the film less susceptible to contamination, in a vacuum environment can be improved purity and compactness, no waste without pollution. Vacuum coating itself is contaminated, but the actual vacuum system will be used in organic coatings, it will also cause pollution, but compared to the wet plating technique, a lot less pollution, high efficiency vacuum coating technology has strong vitality, but it does not mean that vacuum coating technology can completely replace the traditional wet coating technology, and in the thickness of the film, the anti-aging still take advantage of the wet coating method, vacuum coating thin film coating system.
In addition, a solid layer is affected by the process and adhesion, either wet or vacuum coating technology coating technology, if the material surface is not clean and will affect the binding layer material.
