Vacuum equipment refers to a full set of devices removing gas molecules from sealed chambers to form pressure below standard atmospheric pressure (101325Pa), serving as foundational hardware across modern precision manufacturing and high-tech industries.

　　PVD vacuum coating machine is mature mainstream vacuum processing equipment realizing physical vapor deposition thin-film coating under high-vacuum environment, extensively applied to automotive parts, precision cutting tools, sanitary hardware, mobile phone accessories and optical lens surface functional modification globally.

　　Vacuum equipment is essential supporting equipment running through full food industrial chain from raw material deep processing to finished product sealed packaging, covering vacuum freeze dryer, continuous vacuum packaging machine and central centralized vacuum pump station three core equipment types, improving food shelf life while retaining original nutrition and flavor.

　　Cryogenic vacuum pump (cryopump) is a capture-type ultra-high vacuum pumping device different from conventional mechanical transfer pumps, capturing all gas molecules via ultra-low temperature cold panel condensation instead of compressing and exhausting gas outward, capable of reaching ultimate ultra-high vacuum up to 10 Pa with zero oil pollution and extremely clean working environment, irreplaceable for aerospace component testing, high-precision optical coating and semiconductor chip manufacturing.

　　Standardized daily maintenance directly extends vacuum equipment service life by 30%~50% and reduces unexpected downtime failure rate, covering rough pumps, turbo pumps and full-set coating vacuum system three core maintenance modules, an important after-sale technical guide for overseas end-users purchasing Chinese vacuum machinery.

　　Global vacuum equipment industry evolves toward intelligence, oil-free energy-saving and customized high-precision design driven by downstream semiconductor, new energy, green surface treatment and aerospace high-end manufacturing expansion, with Chinese vacuum machinery manufacturers gradually improving core technology competitiveness and expanding global export share year by year.
