Shanker Wire Products Industries (SWPI) have been engaged in manufacturing exclusively weights since 1961. The nature of the world is changing very rapidly due to revolutionary development in the field of Science & Technology. It has brought a marked change in the requirement of weights of various specifications, shapes, sizes, designs etc.

Organisation Internationale de Metrologie Legale (OIML) - the apex body of Weights & Measures in the world - had issued its first International Recommendation for weights vide IR No. 1 & 2 in 1968 and SWPI started manufacturing weights according to the said recommendation in 1972. the sample of their weights were submitted to the OIML who appreciated the same vide their message dated 3rd August,1973 .”

Not only that, OIML have also recognised SWPI as one of the suppliers of Cast Iron Weights and had published their name under the heading of suppliers of Cast Iron Weights of OIML (or other) specifications on page 55 of FOURNISSEURS d' EQUIPMENT de CERTIFICATION issued in mars, 1987.

There are two systems of Weights:

1.

One is the Newton system evolved and developed by the great Scientist Sir Isaac Newton. Mass value of such weights do require some adjustment depending upon the gravitational force of the earth at the place of weigh-ment / use.

2.

The other system where the weights are adjusted against a standard weight without considering the effect of gravitational force of the earth. In this system a prototype based on various scientific observations and calculations is prepared and placed at a specific place. A chain of comparison& adjustment gives rise to various standard weights. In other words the user's weights have traceability with the prototype.

AND SWPI manufacture weights of both the systems.

The Photographs shown in the Website are only of those weights which are in regular range of our production but we have the capacity to manufacture weights ranging from 5g to 1000kg a piece of any specification as desired by buyers.

Due to the quality of SWPI's products and its performance specially in the field of international markets and it's R&D , SWPI have been honored at many occasions at the Zonal, National & International levels.

Accuracy in Weighing Systems through-out the world is SWPI's Motto.
