Product Category 1: Vacuum System Components and Integrated Solutions
Definition and Positioning
SUNFUN Group's vacuum system product line represents one of the most comprehensive portfolios in the precision manufacturing segment. We manufacture vacuum chambers, vacuum piping, multi‑series flanges (JIS VG‑VF, NW, ISO, KF, CF, and fluid flanges), vacuum valves (including gate valves and adapters), supports and brackets, and vacuum pumps. This breadth of coverage—from chambers to pumps—enables us to deliver integrated vacuum systems rather than isolated parts, simplifying procurement and installation for our customers across semiconductor, photovoltaic, and industrial coating industries.
Core Functions and Technical Features
Every component within our vacuum system family is engineered to meet rigorous performance standards. Our vacuum chambers and piping are fabricated with surface finishes that minimise outgassing and maintain pressure stability. The flange series—JIS VG‑VF, NW, KF, ISO, and CF—are designed to accommodate different vacuum levels, temperature ranges, and installation standards, ensuring compatibility with both legacy systems and next‑generation equipment. Our vacuum valves incorporate advanced sealing technologies that maintain integrity under high‑vacuum and ultra‑high‑vacuum conditions, while our pump portfolio covers roughing, turbo‑molecular, and dry pumping technologies. The integration of intelligent monitoring interfaces enables real‑time pressure and flow control, positioning these components within the broader framework of industrial systems and engineering components that support automated manufacturing environments.
Typical Application Scenarios
SUNFUN Group's vacuum systems serve multiple industrial sectors. In semiconductor manufacturing, our components enable deposition, etching, and ion implantation processes that must operate under precisely controlled vacuum conditions. In photovoltaic production, our vacuum technology is critical for thin‑film coating and thermal treatment stages. Beyond these high‑technology applications, our vacuum systems are also deployed in vacuum metallurgy, scientific research laboratories, aerospace component testing, and industrial coating facilities. The availability of multiple flange standards—JIS, NW, ISO, KF, and CF—allows our components to be integrated into equipment from diverse global suppliers, making them a versatile choice for system builders and end‑users alike.
Differentiation from Other Categories
Unlike single‑product suppliers, SUNFUN Group's vacuum system product family offers a complete ecosystem of interoperable components. This eliminates the compatibility risks and performance mismatches that often arise when assembling systems from multiple vendors. Our ability to supply chambers, piping, flanges, valves, and pumps from a single source reduces procurement complexity, streamlines installation, and simplifies maintenance. Our 0.001‑mm precision machining capability—paired with the ability to produce components from 0.1 grams to 150 tons—ensures that even the most demanding custom vacuum components meet exacting dimensional specifications.
