An important trend today is the continual improvement of product quality with the objective of increased customer satisfaction, but also leading to more effective cost reduction management. Effective quality management in a company also enables increasing production productivity thanks to the increasing amount of top-quality products made and the consequent minimalization of repairs of non-conforming workpieces. This contribution deals with one of the important tools for ensuring quality in the production process using the FMEA (Failure Mode and Effect Analysis) method used in the production of roller bearings for the automobile industry.

Currently, companies have been trying to make the use of their technology, manufacturing capabilities and experienced workforce to respond flexibly to market demands. Collecting and processing of all relevant data in the company is one of the key points to which increased attention should be paid so as to maximize the efficient use of own resources and consequently ensure a continuous reduction of production costs. The article deals with the use of burning machines in engineering company. The product range involves the production of burnouts from standard and special materials as well as welded steel parts of structures. The company has long struggled to optimize the material and information flow between particular production operations. This paper was focused on information flow logistics, which proved to be the biggest weakness of the central material preparation department during the bottleneck analysis. The scientific contribution of the resolved issue can be seen mainly in the possibility of interconnecting process analysis and optimization of material and information flows.

One of the most important activities in the management of companies is the continuous improvement of products quality concerning their sustainability and better market position. The submitted paper aims to optimise the production process in the production of weldments. The study revealed a significant number of dimensional and threaded defects on the welded chassis of the loader. One possibility of continuously increasing the required performance of a company is to eliminate the number of non-conforming products using the tools of the Six Sigma methodology. This policy must be introduced by a company into the business processes management if a company wants to successfully meet the customers´ needs and improve the processes while cutting the costs of production. The resulting analysis focused on the selected type of defects to reduce their occurrence using the Six Sigma tools, specifically the DMAIC improvement cycle. The presented approach and the results obtained highlight the importance of applying quality tools in practice and their undeniable contribution in improving performance and quality, reducing the number of defects occurring and reducing the cost of poor quality in production, both now and in the future.

This paper deals with the use of lean manufacturing methods to streamline the welding line in the automotive industry. The automotive industry is constantly developing and innovating its production environments and technology because of growing competition on the market and customer demands. Current trends of car makers include pressure to reduce costs and increase production efficiency. With the commencement of new technologies, the production lines began to innovate and the production cycle began to constantly accelerate. The paper deals with the reconstruction of the welding line, which produces parts for the rear axle of a compact SUV. The case study aims to identify bottlenecks and set innovation plans and their evaluation in possible implementation. In the paper, lean manufacturing methods are applied in order to determine the ideal solution for ensuring the quality and ensuring the efficiency of the production line, leading to cost reduction. Through these innovations and modernizations, the company will be heading for digitalisation that changes the core of the industry.
