Sunder Plast (Private) Limited Quality Control means the control of “goodness” or the “excellence” of a product. In this ever-changing pattern of producing and making things, if “quality” of a product is not maintained then it is difficult for the product to survive. Selection of raw materials to the assessment of finished product; this entire chain of functions is effectively linked through quality control. Unless a job is thoroughly and continuously checked for quality, at the strategic stages, it is never possible to always get a good quality finished product. Quality control increases output and reduces breakdown. It seeks to ensure that the finished products conform to the specified standards of performance, utility and reliability. Hence, in any field today, quality control has become an indispensable tool of modern management.
