Evaporation coating operation and the effect of vacuum coating machine

  Now the vacuum evaporation coating machine is vacuum technology development of more mature since a production equipment, the machinery by electrified motor to a specific place within the location of the coating material for heating. Makes the material is heated evaporation can get after, and then through the evaporation of groups of atoms, or ions cover prepared substrate, forming, and make it slowly form a thin film form. Then removed substrate that enables the film to attach to the objects need to coating surface, forming a layer of thin film, after cooling, the film is gradually formed. This is at present in the form of the evaporation coating machine main approach, is also the most commonly used vacuum coating machine for machining method.
 Due to the application of vacuum coating machine is very widely, has penetrated into vehicles, civil engineering, mechanical, packaging, environmental protection, etc., so now the vacuum coating is the main form of surface treatment. Now on the surface of the vacuum machinery for processing can realize stable appearance packaging, it's the value for the object or very large, both to ensure that an object's surface has a certain luster, can guarantee the machine for coating play a protective effect of items.

The pressure of the vacuum coating machine control system

 

 Now most of the items needed for surface treatment will be used in the vacuum coating equipment for processing, because this surface processing machinery is not only make rough surface with smooth surface, and general also has the improving effect of the surface gloss. So, not only on the surface of the coating also played a role in surface protection, though not as strong, but to prevent surface erosion. When it comes to such machinery, at present because it is processed in a relatively vacuum environment, so the influence factors of the outside world for items coating was also affected by the decreased a lot. Where machinery is for processing in the vacuum environment, so need to control the pressure, here to introduce the pressure system of vacuum coating machine.
In vacuum unit, due to the need of vacuum technology, hope vacuum chamber pressure maintenance on a given value, however, due to the change of vacuum indoor put gas or vacuum pump suction rate interference factors, such as the vacuum chamber pressure deviates from the given value, so need to automatically adjust the pressure. For small vacuum pressure automatic adjustment, usually choose pressure controller to achieve them. So after research design, and many times of experiments was designed to produce the vacuum coating machine pressure control instrument control system, this is the most used in the vacuum coating equipment control device for pressure balance.

The various types of vacuum coating and working methods

   

Now according to the technical requirements for vacuum coating equipment select different standards and types of coating equipment, its type resistance evaporation, electron beam evaporation, magnetron sputtering, magnetron sputtering, ion plating, hollow cathode arc ion plating, ion plating, etc. Fixture working method of the rotation, light coating machine revolution and the revolution and rotation combination method, users can according to the substrate size and shape, put forward the corresponding requirements, changes the speed of the scale and precision: general adjustable and frequency control of motor speed, etc. By the mechanical pump and the vacuum system, distributed pump, oil pump, enlargement pump, roots pump and molecular pump crucible round and match them all kinds of pneumatic, manual, electric valves, pipes, etc. According to technical requirements selected plating method and the method, to choose a suitable coating machine, and coating mechanical type so much, and the internal gear is also there are so many kinds.
If it is not the right choice, then it will be difficult to play for the biggest effect of vacuum coating machine, and the above said tial mainly suitable for use to metal materials and surface treatment in crystalline materials. For resistance evaporation, electron beam evaporation is suitable for use to the city a kind of common items of surface treatment, and said to the fixture, light coating machine is typical of the kind.

Why are fond of using plastic vacuum coating machine for coating

                 

 Current of vacuum coating machine used in coating industry is very broad, but now the vacuum coating is no longer as usual use metal materials and other materials or crystal and the conductor to coating processing. These materials are more suited for surface machining was carried out on the surfaces of materials, why now is plastic push the latecomers visibly instead? Then the small make up to you to introduce plastic material that why can win material such as metal plating status.
  Why are fond of using the plastic vacuum coating machine for coating? Because plastic for the coating, its plasticity is good, a little heat, we can shape for it to shape. Because of his shape, shape it into a layer of soft film, so a thin layer of thin film by vacuum coating machine in plating surfaces can have certain protective effect. Now mobile phone sticker also principle.

Introduction to the vacuum plating equipment common vacuum coating method

                 

  Vacuum plating equipment is used for a class of need in the vacuum coating equipment, coating method is called vacuum coating method. Vacuum coating method is in the heart of the vacuum evaporating metals, alloys or compounds (or sputtering), make them deposited on the surface of the substrate, method. On the material surface plating a layer of thin film, can be material to obtain some new chemical or physical properties. Vacuum coating method is a new coating process, also known as dry coating method, compared with the wet plating method, it has the features: 1, the film less susceptible to pollution, get good coating compactness, high purity. 2, wide range of membrane materials and the selection of base material, the film thickness can be controlled, with different vacuum plating equipment preparation of different functional thin film. 3, membrane layer and substrate adhesion, strong. 4, does not produce waste, not cause environmental pollution.
Common coating methods include vacuum evaporation, sputtering, ion plating, etc. These three coating methods have their advantages and disadvantages, including ion plating used most widely, its characteristic is: can plating materials including metals, alloys, compounds, such as membrane material evaporation method with evaporation and sputtering, membrane layer adherent strength is good, the plating film density high, uniform, can all plated surface.

Vacuum coating process on the environment What are the requirements?

                   

  Vacuum coating process on the environment What are the requirements? Vacuum coating process, the vacuum coating process the substrate (ie the substrate) surface cleaning treatment is very important. We should be careful before plating the substrate cleaning process before entering the coating chamber, to the workpiece to oil, decontamination and dewatering purposes. Then the vacuum coating technology for the environment ask for?

  We know that the surface of the substrate is generally contaminated dust from all parts in the processing, transportation and packaging are adhered, lubricants, oil, polishing paste, oil, perspiration and other objects; parts of the surface oxide film generated in moist air; parts surface absorption and gas adsorption. These contaminants can be employed basically to oil or chemical cleansing method to get rid of.

 After the cleaning process for vacuum coating process to clean the surface, in the atmosphere can not be stored in an enclosed container or storage cabinet cleaning to reduce dust contamination. Aluminum oxide with a storage container just a glass substrate, can minimize the adsorption of hydrocarbon vapors. Because these containers preferentially adsorbed hydrocarbons. For highly unstable, sensitive to water vapor surface, generally should be stored in a vacuum oven.

  Indoor dust clear coating, the device is relatively high cleanliness workshop, interior height to keep clean vacuum coating process the basic requirements of the environment. Air humidity areas, in addition to the substrate before plating, vacuum chamber components carefully cleaned, but also baking degassing. To prevent the oil into the vacuum chamber, note that oil diffusion pump oil back on the high diffusion pump heating power must take measures to block the oil.
