Analysis and Improvement of the Galvanized Wire Production Process with the use of DMAIC Cycle

Open access


The article presents the results in the scope of analysis and improvement of the galvanized wire production process with the use of Six Sigma's DMAIC cycle. The basic problem was identified - incorrect wire diameters after galvanizing and specific tools and methods were used to analyze this problem and look for its solution. The potential of Pareto analysis, SPC method, control plan, 5WHY analysis was used. As a result of the analyzes carried out, the source cause was identified - contaminated containers dispensing the preparation maintaining the temperature in the galvanizing unit. To eliminate the problem, maintenance of the machine used to cover the bare wire with zinc was carried out, which allowed to achieve the following results: standstills at the Drawing and Galvanizing Department were eliminated, the duration of the manufacturing process and the percentage of products beyond the specification were significantly reduced.
