Manufacturing

The company prides itself with the state-of-art infrastructure. The technology-driven solutions are coupled with a sophisticated business infrastructure to define the unique position in the market. The manufacturing facility of the company is strategically located in the industrial township of Howrah, West Bengal, having a manufacturing capacity of 18000 MT per annum.

A highly educated and professional team ensures that the raw material is procured in a highly professional manner after lab testing for chemical composition and diametric accuracy.

We have 2 processes of manufacturing, namely Cold Drawing and Turning and Peeling.

Cold Drawing

Raw Material

Hot rolled steel bars are used as raw material. Because the hot rolled products are produced at elevated temperatures (1700 - 2200 Deg. F. i.e. hot rolling), they generally have a rough and scaled surface and may also exhibit variations in section and size.

Cleaning

Abrasive scale (iron oxide) on the surface of the hot rolled rough stock is removed.

Coating/Pickling

The surface of the bar or coil is coated with a drawing lubricant to aid cold drawing.

Pointing

Several inches of the lead ends of the bar or coil are reduced in size by swaging or extruding so that it can pass freely through the drawing die. Note: This is done because the die opening is always smaller than the original bar or coil section size.

Drawing

In this process, the material being drawn is at room temperature (i.e. Cold-Drawn). The pointed/reduced end of the bar or coil, which is smaller than the die opening, is passed through the die where it enters a gripping device of the drawing machine. The drawing machine pulls or draws the remaining unreduced section of the bar or coil through the die. The die reduces the cross section of the original bar or coil, shapes the profile of the product and increases the length of the original product.

Finished Product

The drawn product, which is referred to as Cold Drawn or Cold Finished, exhibits a bright and/or polished finish, increased mechanical properties, improved machining characteristics and precise and uniform dimensional tolerances.

Turning and Peeling

Pre straightening

The raw material is straightened before being peeled in order to maintain the accuracy of peeling. If the raw material is not found up to the desired standard, it is not allowed to pass to the next stage.

Peeling

In this stage, the straightened raw material passes through the peeling machine and is peeled as per the required size by a cutter made out of tungsten carbide. The rotatory motion of the cutter ensures accurate and even peeling of the raw material.

Post Straightening & Polishing

The material is now re-straightened and polished to remove any surface flaws and to give it a pimple shining look. Extreme care is taken while loading the material for transportation and shipment. Lacquer is applied to the material to prevent it from rusting for a long period of time.
