Change-over time reduction and stock organisation in a truck cooler assembly line

Valeo Engine Cooling in Mjällby mainly produces truck coolers. At the production site, there is on-going work to phase out the automobile cooler manufacturing and concentrate the production to one facility. At the same time the main production flow needs to be improved.

The purpose of this Master’s Thesis is to analyze the flow of coolers from the brazing furnaces through the different crimping and welding assembly stations, to find problem areas and implement changes to improve the situation. The analysis has pointed out three different areas:

The need to increase throughput of the brazing furnaces and lower the work in progress levels by reducing change-over times
The necessity to organize the crimping stock in FIFO and improve the layout
The importance of having a separate stock area assigned for manual welding assembly
