Quality assurance in the glass industry

Abstract

The following three chief functions characterize the way in which the quality-assuring measures have an effect on the company events: quality planning, quality control, quality evaluation. The functions of quality assurance extend to all classical product generation phases, the duties in respect of the following being of a varying character: phase of development, design, prototype, phase of preparation (provision), phase of production (manufacture) and service phase (practical proof). The quality circuit, a closed series including all measures relevant to quality, guarantees prompt feed-back of the results to a short-dated adjustment of variations, thus contributing substantially to the prevention of defects. The quality assurance system is presented here in sections of a production line serving as an example.
