Vacuum coating machine

Vacuum coating machine mainly refers to a kind of coating that needs to be carried out under a higher degree of vacuum. It includes many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, and PLD laser sputtering deposition. The main idea is divided into two kinds of evaporation and sputtering.

The substrate that needs to be coated is the substrate, and the plated material is used as the target. The substrate and the target are in the vacuum chamber.

Evaporation coating generally heats a target to evaporate surface components as radicals or ions, and settles on the surface of the substrate to form a thin film through a film formation process (scattering-island structure-vagular structure-layered growth). For sputtering type coating, it can be simply understood that the target is bombarded with electrons or a high-energy laser, and surface components are sputtered out as radicals or ions, and finally deposited on the surface of the substrate, undergo a film formation process, and finally form a thin film. .

Coater using steps

First, the operation of the electric control cabinet

1. Open Water Pump, gas source

2. Turn on the main power

3. Open the pump, vacuum gauge power supply, vacuum gauge position V1 position, waiting for the value is less than 10, then enter the next operation. It takes about 5 minutes.

4. Open the mechanical pump, pre-pump, turn on the turbo pump power, start, vacuum gauge switch to V2 position, pumped to less than 2, about 20 minutes.

5. After observing that the turbomolecular pump reading reaches 250, turn off the pump. Open the front machine and the high valve to continue vacuuming. After the vacuum is reached to a certain degree, the right high vacuum gauge can be opened to observe the vacuum. Only when the vacuum reaches 2×10-3 can the electron gun power be turned on.

Second, the DEF-6B electron gun power cabinet operation

Total power

2. At the same time, open the electron gun control I and electron gun control II power supply: press the electron gun control I power, delay switch, delay, power and protection light is on, delay and protection light off after three minutes, if the back door is not closed or the water flow relay has Fault, protection light will always be on.

3. Open the high voltage, the high pressure will reach 10KV or more, adjust the beam to about 200mA, the screen grid is 20V/100mA, the filament current is 1.2A, the deflection current swings between 1~1.7.

Third, the shutdown sequence

1. Turn off the vacuum meter and turn off the molecular pump.

2. When the molecular pump reaches 50°C, the high valve, the preceding stage, and the mechanical pump are turned off successively. This takes about 40 minutes.

3. When it is less than 50, turn off the pump again.

The scope of application of vacuum coating machine

1. Architectural hardware: Bathroom hardware (such as faucets). Door locks. Door handles. Bathrooms, door locks, hardware hinges, furniture, etc.

2. Watchmaking industry: Can be used for case. Coating of straps, crystal products

3. Other hardware: leather hardware. Stainless steel cutlery. Glasses frames, knives, molds and so on.

4. Large parts: car wheels, stainless steel plates, signboards, sculptures, etc.

5, stainless steel pipe and plate (various types of surface)

6, furniture, lamps, hotel utensils

7, locks, handles, bathroom hardware, golf head, stainless steel cutlery, blood and other hardware products plated super hard decorative film.

8, watches, straps, glasses, jewelry and other accessories plated super wear-resistant decorative (gold and silver) nano-film and nano-film and nano-laminate film.
