Analysis of non-conforming production in an engineering company

Abstract

In practice, there is a very often inaccurate recording of nonconforming production, resulting in waste and increasing wastefulness. This has a direct impact on the efficiency and profitability of production. This article deals with the analysis of non-conforming production in terms of the development of retained units for evaluation by the quality department and in terms of the development of scrap in a company involved in the production of tubes for the automotive and energy industries. The bottlenecks in the production process have been investigated and analysed, and the necessary measures have subsequently been determined. A new perspective on the issue of mismatched production was obtained, and new solutions were found that helped the company improve the efficiency of its production processes and thus increase its competitiveness. The analyses of non-conforming production presented in the paper are applicable in many enterprises. When the efficiency of production is increased, unnecessary losses are avoided. This will satisfy the philosophy of lean manufacturing, which aims to produce products in the shortest possible time with minimal cost.
