We at NIF ISPAT Ltd., implement an ascetic quality control system, which is customer oriented and is continuously improved.

To accomplish our targets, we follow the policy of constantly motivating and developing the competent human resources to cope with the variable customer requirements. In addition, we try to attain higher productivity level together with improved quality performance to achieve maximum customer satisfaction

Our highly qualified engineers and a state-of-the-art R&D unit ensure that our products are of the superior quality. The produced goods undergo a complete physical testing including Casting’s Hardness, Load Testing, Load Tensile, Transverse and Chemical Analysis to meet the requirements of the globally accepted quality standards.

Quality Mantra :-

Trials Procedure : Where new patterns are involved or where designs have been improved, the component has to undergo a pre-production trials procedure. Few samples is cast and monitored through the various stages of production . Emphasis is placed on exceeding product specification and on ease of manufacture. The philosophy is that a product that is easy to make will generally be of better quality than a component which creates manufacturing problems.

Process Control : Quality control starts with checks on raw materials and is then applied throughout the manufacturing cycle. To ensure this there is an in-house quality assurance manual which sets out all the disciplines that go to make a casting with emphasis on quality assurance at every stage.

Material Analysis : A sample of every melt of metal produced is analysed in laboratory before molten metal is poured. This gives an instant and permanent record of the chemical analysis of every casting produced from a melt. Traceability is maintained by the issuing of a unique number to every casting produced from any melt. Pyrometer is used at the pouring stage to ensure heat temperature along with Spectro and Micro analsysi of each melt.

Visual Analysis : A team of inspectors check and report on castings at every stage of manufacture. In the case of machined and heat treated items this involves four separate visual and dimensional checks on surface finish and adherence to drawing tolerances

Testing : To check physical properties universal testing machine is used. A wide range of equipment is used including Brinell testing machine and load test machine. Also a variety of special equipment is available on site for testing particular items. For instance hydro-pressure testing equipment , pull & tilt test machine etc.


INSPECTION

It is an important activity and item is inspected at each stage during production depending on the procedure adopted right from the raw material.

Raw material, Sand, Chemicals, Additives, Paint, Scrap.
