Silver Plating Equipment
Rhodium-Ruthenium Plating Equipment (JYC-RhRu-Series)
Built for Medical and Aerospace Applications
Implantable medical devices like pacemaker electrodes and neurostimulation probes. Precision instruments and aerospace sensors. These products need the best biocompatibility and corrosion resistance. Our Platinum Plating Equipment meets this need. Platinum coating purity reaches 99.95%. It is chemically very stable and biocompatible. It passes ISO 10993-5 cytotoxicity testing. It also has high catalytic activity. Coating thickness is typically 1 to 5 microns. Hardness is controlled at 150 to 200 HV. This meets ASTM B561 and MIL-P-45209. Our clients include national research institutes like China Electronics Technology Group and Beijing Microelectronics Institute.
Materials and Construction for Ultra-High Purity
The entire line uses PFA or quartz tanks. These materials do not leach heavy metal ions. Pre-treatment includes plasma cleaning or anodic electrolysis stations. The substrate surface reaches atomic-level cleanliness. The solution uses high-purity platinum salt with platinum content over 99.99%. Double-layer PP filter cartridges provide 0.2-micron precision.
Three Core Advantages
First, coating purity is extremely high.
DC or pulse current processes are used. Coating impurity content is below 50 ppm. After 72 hours in aqua regia, the platinum layer shows no discoloration, peeling, or dissolution.
Second, adhesion is excellent.
A nickel or gold underlayer is used first. Platinum layer adhesion meets ASTM B571 qualitative adhesion testing. In 90-degree bend and file tests, the coating does not peel.
Third, thickness is uniform.
Rotating cathodes or shielded anode designs are used. For 0.1 mm diameter micro-wires or complex shaped parts, thickness uniformity is controlled within ±8%.
What Buyers Often Ask
Buyers ask us: "Medical device customers need FDA and CE certification. What support can your equipment provide?" We can provide Class 100 cleanroom-grade platinum plating lines. The equipment supports rack, barrel, and continuous strip selective plating. Key process parameters like temperature, pH, and current density are fully automatically closed-loop controlled by PLC. We also provide complete platinum solution recovery and regeneration services. Our cooperation with Southeast University on medical-grade material plating proves our technology is fully qualified.
