MECHANICAL POLISHING / BUFFING

Mechanical Polishing / Buffing are finishing Process for smoothing a work piece surface to achieve “RA” Value by using multiple tools & wheels with finishing products at multi stages.

A Common Misconception is that a polished surface has a mirror bright finish, however most mirror bright finishes are actually buffed.

Mechanical Polishing is often used to enhance the looks of an item, Prevent contamination of medical instruments, Improve “RA” Value, Remove oxidation, Create a reflective surface or Prevent corrosion in any stainless steel surface.

OUR PASSIVATING

Passivating is the chemical treatment of a stainless steel surface with a mild oxidant such as a citric acid and nitric acid base solution, this is typically done to remove any free iron from the surface of the metal, which enhances the corrosion resistance of the stainless steel surface and accelerates the re-formation of the passive layer

Facility :In house and on site services.

Passivation: What is Passivation?
Passivation is a chemical cleaning process that is designed to remove free iron and other ferrous contaminants from the surface of stainless steel parts. By removing the contamination from machining, stamping, etc., you are helping restore the material to the original mill condition and corrosion specifications.

METAL PICKLING

Pickling paste used to remove the black oxide marks of burn seal left during welding of Stainless Steel. Also pickling chemical descaling is typically used to remove oxide layers resulting from welding heat trating and other high temperature operation. All of these oxide layers rust a spot are generally referred to as ‘scale’ and must be removed prier to electropolishing or passivating, sometime old buffed s.s. equipment rusting by oxidation during process we used our chemical for remove oxide scale and maintain as semi bright buff finish without mechanical polishing . Pickling is sometimes referred to as Acid whishing.

Metal Pickling is a process intended to dissolve heavy oxides and contaminates, and remove the effects that real-world handling has on the surface of stainless steel. The real-world fabrication, welding and handling of stainless steel
components will leave surface contaminates. These contaminates, which may include weld oxides, scale and embedded particles, will hinder stainless steel’s natural ability to resist corrosion. An acid-based solution referred to as pickle liquor is used to clean and remove scaling from the steel during the fabrication process.

ELECTRO POLISHING

There are two types of Electropolishing facility.

Direct electropolishing
Electropolishing after mechanical polishing

Commercial applications for electropolishing have been in use since the early 1960’s. Electropolishing is a process by which metal is removed from a work piece by passage of electric current while the work is submerged in a specially-designed solution. The process is essentially the reverse of electroplating. In a plating system, metal ions are deposited from the solution onto the work piece; in an electropolishing system, the work piece itself is dissolved, adding metal ions to the solution.
