Quality & Assurance
Inspection and Documentation Records, QCP
Raw materials are purchased initially from reputed vendors with
correlated test certificates.
After the materials arrive at our shop they are cross checked with the
TC given by the vendor and a sample from above lot is sent for check
testing at reputed Lab. Heat No. are punched on confirmation of Lab.
Report.
Prior to manufacturing each item is stamped with the related Heat No.
and the amt. of pipes or raw materials debited from the stock book.
Dies are checked from time to time if the dies are over-sized and
rectification is arrived prior to Manufacturing. All internal inspection
stage wise books are maintained. Where in day-to-day progress of
manufacturing dimensions are noted and seen that they are within
permissible limits.
During the manufacturing, inspection is carried out to check if the
cracks or deformities are present, if found the material is rejected.
After the product is manufactured, a 100% dimensional check is
carried out.
The samples of the batch are sent for testing for Micro and chemicals
analysis, on receiving a satisfaction report the items are etched and
stored in a proper location of finished goods.
