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).

Why Technology & Supply?

We have been working in this field since 1980 in close cooperation with leading universities and enterprises of Belarus, the Russian Federation and Ukraine.

Environmentally friendly

The polishing solution does not contain acids, does not require special treatment facilities, and meets all sanitary standards.

Productivity

The process of plasma polishing is several times more productive than the mechanical polishing method, improves working conditions

High quality

Achieved through high-quality components and extensive experience of specialists. Repeatability of high quality polishing of products of complex shape from cycle to cycle.

Application EPP

The EPP machines are most often used to quickly achieve a mirror, uniformly shiny and high-quality surface on stainless steel products (AISI 304, AISI 316, AISI 316T, AISI 321, etc. ), for finishing, decorative polishing of parts made of copper and copper alloys, for polishing some grades of titanium and carbon steels.
  • 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.

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.

Composition of plasma polishing equipment

The plasma polishing machine includes three main parts:
  • Working bath with a treatment solution, mechanism lifting - lowering and protective casing, technological tools, pneumatics - hydraulics.

  • Transformer for special applications.

  • Rack power and control, which allows to carry out the process in an automatic mode with the help of Siemens controller.

How it is working?

When products are lowered into the solution, a plasma forms around the part, the surface improves by 2-4 classes. Within 3-5 minutes of the plasma polishing process, a mirror shine appears; cleaning of welded seams occurs within 1-2 minutes; blunting sharp edges, burrs within 2-3 minutes; brightening, surface activation 30-60 seconds. Many before and after examples of plasma polishing with cycle times are provided at the bottom of the page (videos, photos).
