The paper deals with the analysis of assembly process for assembling blowers in smallscale production, as well as its optimization and automation. In the theory, the products and assembly process are presented. The approaches of Industry 4.0 and value stream analysis were analyzed in more detail, including material supply, the assembly process, and packaging. First, a time analysis of the entire production process was done in the department for electronically commutated blowers. The analysis identified possible production optimizations without financial investment, as well as upgrades that also require financial analysis to justify the investment. After process optimization, a time saving analysis was done, which directly led to information on increased capacity. In addition to the process, possible adaptations of the blower design were analyzed to improve assembly processes. Due to the large number of different products, the improvements will also help us with production planning in the future and reduce downtime due to material shortages.
