Industrial Sanitary PVD Sputtering Deposition Coating Equipment

The magnetron‑sputtering PVD coating equipment is special for sanitary hardware. It can deposit high‑purity, high‑adhesion and corrosion‑resistant functional and decorative coatings on substrates including stainless steel, copper alloys, ceramics and plastics. Suitable for mass production of sanitary‑grade components such as faucets, shower heads, kitchenware and medical hardware, it improves product output performance and service life.

Product Features​

1. Chamber Structural Design

Sanitary-grade chamber structure design: the chamber interior undergoes thorough cleaning and optimization to reduce dust accumulation in dead corners and prevent impurities from detaching and contaminating the coating layer during the coating process; the chamber seal and piping components meet the production requirements for sanitary components, eliminating the risk of leaching and heavy metal leaching from the coating layer; the finished product meets the testing standards for bathroom contact products. Strict vacuum leak rate control throughout the machine ensures a high level of cleanliness in the coating environment, resulting in a high-purity coating layer free of pinhole defects.

2. Magnetron Sputtering Deposition System
Equipped with a composite sputtering target source system of DC / MF / RF, it is capable of depositing metallic films, alloy films and corrosion‑resistant hard compound films. Films produced by sputtering feature high density and strong film‑substrate adhesion, with bonding performance far superior to conventional electroplating. Nano‑level precise control of film thickness is achievable, delivering excellent film uniformity over the full surface of workpieces and consistent color difference for mass‑produced parts.
The low‑temperature sputtering process reduces thermal deformation of substrates, enabling stable processing for thin‑wall and precision sanitary hardware components.

3. Stable and Reliable Vacuum System
The self‑developed vacuum pump set by Puyuan features pumping speed matched to the mass‑production cycle of sanitary‑grade parts, enabling rapid achievement of process ultimate vacuum. The vacuum system is oil‑contamination resistant and suitable for long‑term continuous mass production. With stable equipment operation, low failure rate and short production cycle, optimized energy consumption helps reduce overall production costs for factories.

4. Intelligent Machine Control System
Adopts touch‑screen PLC fully‑automatic control system, which can store multiple complete coating process recipes for sanitary products. Parameters including sputtering power, gas flow, bias voltage and temperature are controllable via closed‑loop regulation. It is equipped with functions of operation monitoring, fault alarm and parameter traceability, lowering the threshold for manual operation, facilitating process replication and mass‑production management, and enabling convenient maintenance and overhaul.

5. Wide Substrate Compatibility and Customizable Processes
Compatible with mainstream sanitary hardware substrates such as stainless steel, brass and zinc alloy. It can produce corrosion‑resistant, salt‑spray‑proof and wear‑resistant decorative coatings to meet stringent salt‑spray test requirements for sanitary products. Non‑standard customization is available: chamber dimensions, target positions and tooling fixtures can be tailored according to customers' workpiece specifications. Turnkey solutions with matched coating processes are also provided.
