Plasma Technology Limited PTL has developed Electrolytic Plasma Polishing EPP technique to polish different material surface. Unlike the electrochemical polishing, EPP process takes place in solution of inorganic salts and is an ecologically safe polishing technique. PTL can provide turnkey service for the technique.   In EPP process, the metallic workpieces will be anodically polarized and are placed in an electrolytic bath. The electrolyte consists of a solution of about 97% water and 2-4% salt. The process produces gas which completely surrounds the workpiece to be polished and results in establishment of plasma layer. This plasma combined with the electrochemical reactions on the workpiece surface led to a reduction of the roughness as well as removes organic and inorganic contaminants with minimal mass loss. Depending on the material specifications the typical material removal lies between 1-5 um per minute. The geometric shape of the component is almost maintained and very low surface roughness (Ra<0.02um ) and high gloss level can be achieved after the process.      EPP100AD Specifications   Item No. Name Descriptions 1 Machine Dimension L1480 x W1080 x H1680 mm 2 Machine Shell SS304 steel 3 Tank Material SS316 steel 4 Sink Volume 90L 5 Salt Amount About 4kg per tank 6 Machine Door  Manual door 7 Hanging Device Sprocket robotic arm lifting and lowering 8 Robot Arm Stroke 500mm 9 Water Supply and Water Level Control Auto water supply and level control by solenoid valves 10 Heating System PID control for heating bars Heating power of 9kW 11 HMI Control Touch-screen + PLC control 12 Power Supply Dimension Integrated into the machine rack 13 DC Power Supply 100A with adjustable voltage and current, forced air cooling 14 Power Consumption 31kW 15 Input Power 3-phase 380V, 50/60Hz, 80A 16 Protection Phase, under-temperature, over-heat and over-current protections 17 Footprint About 5m x 4m         ========================================================  EPP treatment for Stainless Steel SS Watch Components ======================================================== EPP treatment for Stainless Steel SS Vacuum Components ======================================================== EPP treatment for Copper, Brass or Bronze Components ======================================================== EPP treatment for Brass, Copper/Nickel Alloy Coins ======================================================== EPP treatment for Titanium Ti, Titanium Alloy Ti6Al4V and Nickel Titanium Alloy NiTi
