Vacuum coating equipment choice points

Vacuum coating equipment choice points
▲ optional double water-cooled furnace body structure made of stainless steel, carbon steel, or combinations thereof of.
▲ resistive and inductive heating in the form of two kinds, resistance heating materials molybdenum wire (band), tungsten (band), a graphite rod (plate), tantalum rods, nickel chromium wire (with) several types according to different temperature and process requirements for selection.
▲ heat insulation layer metal and composite two, choose according to different process conditions.
▲ vacuum system consists of a mechanical pump, diffusion pump, oil booster, augmentations pumps, vacuum pumps, etc., and they are matched with a variety of pneumatic, manual, electric valves, piping, etc., can choose according to process requirements.
▲ temperature control system can choose different types of thermometer, temperature control and their sensing element.
▲ intelligent vacuum measurement optional digital vacuum gauge and measure the quality of regulation to ensure the accuracy of the degree of vacuum and product reliability.
▲ can be equipped with multi-point recorder for the whole process analysis, quality control and production management.
▲ According device characteristics, manual, semi-automatic, or a combination of control.
▲ according to the requirement with a variety of inflatable type, mass flowmeter, rotameter, to meet the inflation pressure controlled, multiple inflatable requirements.
▲ of water over-temperature, temperature deviation large, furnace, pumps, heat exchangers, etc., phase diffusion pump, furnace inflatable overvoltage, insufficient gas supply pressure, overcurrent and overvoltage, open circuit and other abnormal situations audible alarm and perform the appropriate protective measures.
▲ fast cooling system and the heat exchanger can choose natural cooling cycle mode, may be used for large-capacity electric furnace outer fast circulating cooling system to improve the cooling rate.
