Inspection & Testing Facility
Raw material plays the most important role in fasteners for reliability & Durability purpose so that we are using the raw material of OEM approved CHQ quality (VD route) steel mill. For the batter control we have also developed in-house metallurgical lab in which we are doing inspection & testing of product parameters which is necessary for the raw material as well as for finish good.
Each raw-material is being tested for its chemical and physical properties like chemical composition, Hardness and MPI
(magnetic particles test) Tensile test & micro examination (Microstructure, Decarburization, grain size, Inclusion rating) according to standard procedures & as per OEM’s specifications.
We are also having a Micro Vickers Hardness Tester to measure the hardness on thread zone of the bolt after heat treatment.
For the surface treatment control we have a Coating thickness tester to measure the thickness of coating layer & Salt Spray Test
(SST) chamber to evaluate the SST life of surface coating.
We also have necessary instruments which are required for the dimensional inspection & optical sorting machine for 100% dimensional measurement.
For the long life accuracy of the instruments we have developed the standard room in which calibration activities are regularly carried-out for all the instruments & gauges as per the standard procedure & specifications.
