PURE LEAD

Our companies are competent enough in the supply of Pure Lead Ingot which are being produced from Raw Lead Bullion / Remelted and Secondary Lead Ingots / Lead Scraps through Pyrometallurgical process. The strength we have in our Refining Process is the purity Level we maintain minimum at 99.97% by weight but achieves purity level of 99.985% in most of cases.

In our process by our experience we adopt many such features which ensure Dross-free & smooth top surface of each ingots. We dispatch after staking of 42 ingots in one bundle duly striped.

Our Quality is tested by

Our modern quality control Laboratory consists of Optical Emission Spectrometer (OES) of Spectro Germany make & Atomic Absorption Spectrometer (AAS). Our manufacturing operations to produce Pure Lead Metal / Lead Alloy, Lead Oxides (Litharge, Red Lead & Lead Sub-Oxide), Lead Products (Lead Sheets, Lead Pipes’ plates, wires etc.) are controlled round the clock by experienced Chemists & Q.C. Supervisors.

Gravita follows strict quality standards in all areas of operation right from selection of raw material to ultimate dispatch to its valued customers.

One of the strengths of Gravita is our highly equipped R&D laboratories and our broad technical competence within production of Lead & Lead Products. Our foundry Lead customers have full access to our extensive range of technical services designed to meet their needs.

Gravita laboratory is equipped with latest technology analyzing equipments like Optical Emission Spectrometer, Atomic Absorption Spectrometer.

Our manufacturing operations are driven by quality, from the way they operate, to the customer service standards they set and the products they deliver.

Each heat is being analyzed prior to its pouring Lead into the moulds to ensure proper chemistry, grain size & dross content of the Lead. All elements are controlled within specified limits and proper records are being maintained. Each heat is being assigned a unique batch no which is also marked every relevant ingot to ensure complete traceability at a later stage.

In addition to in-process inspection, a highly experienced and dedicated team ensures complete adherence to the most precise standards. Experts are involved right from choosing the highest quality raw material to application of various techniques to ensure the product’s confirmation to the highest quality standards.

We focus on quality, which makes us to win new opportunities in an increasingly competitive global marketplace. We identify areas for improvement within our quality checks at every stage of manufacturing process to provide our customers with the best value possible in the products we produce in our modern Plant.

Since inception Gravita has not left behind any effort in satisfying its customers by delivering good quality products with cost effective pricing & adherence to the agreed delivery schedules. The prime objective of Gravita has all along been “CUSTOMER SERVICE AND SATISFACTION”.
