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.      EPP50A Specifications   Item No. Name Descriptions 1 Machine Dimension  L678 x W505 x H906 mm Bench Top Model 2 Machine Shell SS304 steel 3 Tank Size L200 x W180 x H100 mm 4 Tank Material SS316 steel 5 Sink Volume 30L 6 Salt Amount About 1.5kg per tank 7 Machine Door  Stepper motor driven glass door via linear guide rails to open and close 8 Hanging Device Stepper motor driven robotic arm via linear guide rails for lifting and lowering 9 Robot Arm Stroke 220mm 10 Water Supply and Water Level Control Auto water supply and level control by solenoid valves 11 Heating System PID control for heating bars.
