The quality assurance dept oversees all important quality functions and performs the following activities :
1) The system controls the quality of all incoming materials as per the raw material test certificate of the material. Randomly checking in each size for chemical and physical properties at Government approved laboratory.
2) During forming pressing forging and heat treatment process control system outlines inprocess checks and controls to be followed during heat treatment and testing.
3) Suitables fixtures and templates are used to maintain dimensional accuracy necessary guages and callipers are calibrated periodically to maintain their acuuracy.
4) Fittings are supplied with test certificate as per approved QAP. Test certificates incorporate chemical composition, mechanical properties hardness detail of heat treatment Ultrasonic test ,Radiography test and stamping details.
