Vacuum coating machine to change the plastic industry

Plastic products surface metallization, applications will be more extensive. Vacuum coating on the surface of the plastic parts can be divided into functional coating and decorative coating. As a functional coating, it can improve the physical and chemical properties on the surface of the plastic parts, such as the size of the plastic parts can be improved stability, electrical conductivity, etc.; As a decorative coating, can make the plastic parts surface with metallic luster, and according to the needs of actual decoration create a different color, such as gold, bronze and metal red, metal green, blue, etc., specific see sample show.
Vacuum evaporation coating machine is the most widely in the application of plastic products. Plastic has easy molding, low cost, light weight, no corrosion and other characteristics, widely used plastic products, but because of its disadvantages restricted the expand application, such as not beautiful, easy to aging, poor poor mechanical properties, heat resistance, bibulous rate is higher. Through the application of vacuum coating technology, plastic surface metallization, combine organic materials and inorganic materials, greatly improved its physical and chemical properties. The main advantages are
A, easy to clean, no dust collection;
Second, make plastic surface conductivity;
Three, improve beautiful, smooth surface, the metallic color, adornment sex is greatly improved;

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.

Vacuum equipment widely used?

Vacuum equipment widely used? Vacuum now this phrase has been widely applied to various fields, vacuum purpose is to protect, vacuum is one of the most clean, the limits of a vacuum there is no pollutants, make the product reduce the impurity hit, and thus to minimize damage and to make up for insufficient and defect in normal circumstances, it is also very bullish on and love the cause of the vacuum of the masses.
Some products, for example, when the coating if exposed to air, will react and air inside of gas and dust, but the use of vacuum coating equipment can avoid these problems.
For food, vacuum can be stored for a long time don't let bad food, the food in vacuum drying, easy deliquescence can keep the same number of cases.
, so to speak, not only in the industrial production, even in daily life, we all can't leave dependence on vacuum, the vacuum equipment manufacturing is based on this, r&d and production of various types of vacuum equipment manufacturers must deeply realize that what's the purpose vacuum, vacuum coating machine, the company said only know that, in the research and development of vacuum equipment modification, don't deviate from the track, can be developed are more likely to make people satisfied with the products.

Vacuum evaporation coating machine and the magnetron sputtering plating aluminum function

Vacuum evaporation coating machine and magnetron sputtering plating aluminum function, electron beam evaporation vacuum coating machine and magnetron sputtering plating aluminum function analysis research, in order to obtain features outstanding semiconductor electrode Al film, we optimized technical parameters, the preparation of a series of superior function of Al thin films. Through theoretical calculation and function test, analysis compared the vacuum coating equipment, electron beam evaporation and magnetron sputtering characteristic of two kinds of method preparation of Al film.
Strict control of Al film thickness is very important, because the thickness of Al film will directly influence the other functions of the Al film, and then influence the reliability of semiconductor devices. About the high back pressure power tube, its high working voltage, current, not necessarily the thickness of the metal film will form into Al membrane current density per unit area is too high, easy to burn. On semiconductor equipment normally, Al thin layer, the continuity of the membrane is poorer, island shaped or mesh structure, lead to pressure welding lead hard, not easy pressure welding or bonding not firm, and then affect the rate of finished product; Al layer too thick, resulting in lithography graphics can't see, when a difficult and prone to marginal corrosion and corrosion "article".
Selects the electron beam evaporation vacuum coating machine, planetary organization uniform rolling when packing film, the probability of each substrate in the accumulation of Al film equality; Planet group gathering in the pot steamed originate, each substrate accumulation rate under vacuum must be flat. Selection of vacuum coating machine magnetron sputtering deposition method, because of accumulation can target current and voltage control, is also sputtering power can regulate and control, so the film thickness has good controllability and repeatability, and can be made in larger appearance even thickness of film.
Reflect the Al film and substrate adhesion between each other forces, it is also an important factor to ensure equipment is durable. Vacuum coating equipment sputtering atom energy is 1 to 2 orders of magnitude higher than evaporation atomic energy. Vacuum coating machine energy accumulation of sputtering atom in the substrate is much taller than evaporation atomic energy conversion, high heat, some high-energy sputtering atom occur, different degree of written representation forms a layer of sputtering atom in the substrate and the substrate layer the amalgamation of the pseudo dispersed to each other, and, in the process of vacuum coating equipment film-forming substrate and activation has been in the plasma is clean, clear the sputtering atom adhesion is not strong, purification and activate the substrate surface, enhanced sputter atoms and substrate adhesion, thus higher sputtering Al film and substrate adhesion.

How a full range of vacuum coating machine equipment maintenance

Continuous use of more than 12 months for vacuum coating equipment, the inside of the pumping speed will be slow, that is about to do a good job cleaning in a timely manner. First filling the air, down connection pipe, unload electric furnace plate and nozzle. Pump cavity and pump gallbladder points three times cleaning, use gasoline to clean again, first with detergent to clean it again, then clean with clear water thoroughly clean. After being dried, rejoin the pump oil, packed pump, and put back into the body, can restart. Before restarting, attention should be paid to leak detection work. Start the maintain pump, close the door, after a few minutes, observe whether diffusion pump part of the vacuum degree is 6 x10 palmer, otherwise for leak detection. Check whether the connection place o-ring seal, or crush seal ring. Eliminate leakage hidden trouble is heating, or diffusion pump oil will burn ring, unable to enter the working state.
Each completed more than 200 coating procedures for vacuum coating equipment, should be a clean the studio. Multi arc ion plating factory house that swab repeatedly with caustic soda saturated solution vacuum chamber wall, (pay attention to safety can not direct contact with caustic soda solution, so as not to burn) purpose is to make up the membrane material plating aluminum react with caustic soda, membrane layer falls off after reaction, and release hydrogen, reoccupy clear water clean vacuum chamber and a cloth stained with gasoline to clean the dirt in the valve, if you need a light coating machine, please contact us, price concessions, service is good.
Thick in the vacuum coating equipment should change new oil pumping work continuously for 30 days. The old oil discharged completely within the pump. Screw bolt playback oil, add new oil to the quantitative.
