Electrolytic Plasma Polishing Machines for Stainless Steel (EPP)

Plasma electrolytic polishing equipment is usually used for polishing stainless steel to a mirror finish. In the plasma polishing process removed a few microns of metal, resulting in the observed gloss, deburring, descaling after welding, blunting of sharp edges and improve the surface quality of the original 2-3 classes.

Unlike the electrochemical polishing the plasma polishing process takes place in solution of inorganic salts that ecologically safe and does not require any special treatment facilities. After polishing, the items must be washed in warm - cold water from the salts. It is necessary to have a bath (from plastic or metal).

Application EPP

  • Polishing stainless steel, structural steel, non-ferrous metals and alloys in mechanical engineering and consumer goods, medical purpose.
  • Polishing, degreasing, surface activation before vacuum deposition or electroplating.

The plasma polishing machine includes three main parts

  1. Working bath with a treatment solution, mechanism lifting - lowering and protective casing, technological tools, pneumatics - hydraulics.
  2. Transformer for special applications.
  3. Rack power and control, which allows to carry out the process in an automatic mode with the help of Siemens controller.

Specifications electrolyte plasma polishing machine

  • Productivity, dm2 / cycle - 1-100.
  • Cycle time, min - 1-10.
  • Transformer power, kW * A - 6-630.
  • The area occupied by the equipment, m2 - 4.

For working EPP necessary

  • Three phase 380 V, 50 Hz.
  • Running tap water or water recycling system.
  • Compressed air.
  • Exhaust ventilation.

Special foundation to accommodate the plasma polishing machine is not required.

Time manufacturing electrolytic polishing equipment 2.5 - 3.5 months.

Warranty - 12 months.

Cost of finishing products for example "EPP-250" you'll be able to calculate the following indicators:

  1. Power 250 kW*A per hour. At the beginning process of power 6 kW/h per 1 dm2. After 1-2 minutes power drops on 15% (as reduced roughness) - about 5 kW/h per 1 dm2.
  2. The cost of the electrolyte about 100-150 dollars per filling the bath. The duration of a refueling 2 weeks.
  3. The area occupied by the machine of 6 m2, with a service area 10 m2.
  4. Equipment capacity 45 dm2 in the cycle. Cycle time usually 5 minutes.
  5. Attendants two people. One operator and one working on preparation of items for polishing. Most often, one person copes - it depends on the complexity of the geometry of theitems.
  6. Flow of process water supplied to the plant - not more than 0.3 m3 / hour.
  7. Compressed air consumption - no more than 0.3 m3 / hour.
