Abstract [sv]

Haglund Industri är ett företag specialiserat på tillverkning av kylar och frysar. Företaget står dock inför utmaningar med frysningsprocessen av en specifik typ av produkt. Varmluftsläckage mellan dörrens karm och magnetremsa resulterar i isbildning som påverkar produktkvalitet och funktion. Problemet uppstår inkonsekvent i specifika produkter och observeras oftast under perioder med hög luftfuktighet. Detta problem påverkar slutskedet av produktionsprocessen, vilket leder till slöseri med tid och energi. Därför behövs en optimeringsmetod för att ta itu med problemet och förbättra produktkvaliteten. Projektet syftar till att optimera frysprocessen och minimera isbildning genom att analysera grundorsaken till problemet och utforma en lämplig lösning. Optimeringsprocessen kommer att beakta produktionslinjen, använda material och miljöfaktorer. Resultaten av detta projekt förväntas förbättra produktkvaliteten, minska produktionskostnaderna och öka kundnöjdheten.

Mättningar och simuleringar gjorda för denna fallstudie visar hur små skillnader i tillverkning kan påverka slutproduktens funktioner. Med hjälp av olika hjälpmedel och strategier i produktionen kan dessa observeras.

Abstract [en]

Haglund Industries is a company specializing in the production of frozen food products. However, the company is facing challenges with the freezing process of a specific type of product. Warm air leakage between the door's frame and magnetic strip results in ice formation that affects product quality and function. The problem occurs inconsistently in specific products and is mostly observed during high humidity periods. This problem affects the final stages of the production process, causing wasted time and energy. Therefore, an optimization approach is needed to address the issue and improve product quality. The project aims to optimize the freezing process and minimize ice formation by analyzing the root cause of the problem and designing a suitable solution. The optimization process will consider the production line, materials used, and environmental factors. The results of this project are expected to improve product quality, reduce production costs, and increase customer satisfaction.

Measurements and simulations made for this case study show how small differences in manufacturing can affect the functions of the final product. With the help of the various aids and strategies in production, these can be observed.
