PRT Metal Finishers

Virugambakkam, Chennai, Tamil Nadu

We are offering manganese phosphating services.Manganese phosphating is extensively employed to improve the sliding properties of engine, gear, and power transmission systems. The use of manganese phosphated coatings for improved corrosion resistance can be found in virtually all branches of the metal working-industry. Typical examples mentioned here include motor vehicle components in brake and clutch assemblies, engine components, leaf or coil springs, drill bits, screws, nuts and bolts, washers, anti-vibration washers, tools, magnet cores, casting interiors and many other small items.

We provides manganese phosphate coating has the highest hardness and superior corrosion and wear resistances of general phosphate coatings.Manganese phosphating is extensively employed to improve the sliding properties of engine, gear, and power transmission systems. The use of manganese phosphated coatings for improved corrosion resistance can be found in virtually all branches of the metal working-industry. Typical examples mentioned here include motor vehicle components in brake and clutch assemblies, engine components, leaf or coil springs, drill bits, screws, nuts and bolts, washers, anti-vibration washers, tools, magnet cores, casting interiors and many other small items.manganese phosphate coatings for conferment of good corrosion resistance, whether a post-treatment such as oil application is to be used or not, are invariably applied by the immersion method.

We are offering black oxide coating.Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. It is used to add mild corrosion resistance, for appearance and to minimise light reflection.

We provides zinc phosphate coating services.Zinc phosphate (zn3(po4)2) is an inorganic chemical compound used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment.

Zinc phosphating is an conversion coating process which is priorly done before painting, powder coating, rubber moulding etc.Colour - grey coating thickness- 7-9 (micron)salt spray - 72 (hrs)

We provides zinc phosphate services.in most operations where the corrosion resistance of finished workpieces must be especially high, conversion coatings are applied using zinc phosphate . This approach is widely used in the automotive industry and in certain sectors of the appliance and electronics industries. Similarly, zinc phosphating is often specified by the armed services, especially for equipment that may be exposed to severe environments. Moreover, many operations using electrocoating or powder coatings, particularly when a one-coat finish will be exposed to the weather, pretreat workpieces with zinc phosphate.

We are offering zinc phosphating is an conversion coating opted as an prior coating for powder coating, rubber molding, painting etc.
