BMW i production - Interview Steve Swanson, Plant Manager Moses Lake BMW SGL

Creel Area. Steve Swanson: This is the creel area. This is the fist step in the carbon fiber process. In this area we take the polyacrylonitral and form it into a web to go into the next step of the process. Oxidation Ovens. Steve Swanson: The next step in the process is oxidation. The oxidation process stabilizes and oxidizes the material in preparation for carbonisation. Low Temperature Furnace. Steve Swanson: The next step in the process is carbonization. We have the low temp and the high temperature furnaces. This process provides the strength to the material. The Moses Lake facility converts polyacrylonitral to carbon fiber. The first step in den process is the creel area. In an other area we take the polyacrylonitral and form it into a web and prepare it for the next step which is the oxidation. In oxidation we oxidise the material and stabilise the material and prepare it for carbonisation. After oxidation the material goes into carbonisation stage where the material is carbonized and the filaments become a very strong bundle of material. The next step is the surface treatment. After carbonisation the material has no functionality. It is sterile at this point. So in this process we edge the outer skin of the material to allow it to a bond with resist system in later applications. After this we size the material, so we put a small amount of sizing on the material and this is really for usability and handlability for our customer. And after this we wind this material onto barrens and ship to our costumer in Wackersdorf. The Moses Lake facility utilises a high level of energy, much more than the other plants in the supply chain. Because of this we have to make absolute sure, that we are using renewable low cost energy for the program. Moses Lake was chosen for the side for our new facility mainly because of the low cost renewable energy provided by the dams on the Columbia basin river. Oxidation Ovens. Steve Swanson: This is the oxidation. This process oxidises and stabilizes the material in preparation for carbonisation. As the material is heated the material changes colour as the oxidation level increases. Oxidation Ovens. Steve Swanson: This is the second stage of oxidation were you can see the colour changes as the oxidation level increases. Oxidation Ovens. Steve Swanson: This is fully oxidised black carbon fiber. This material now is prepared to go to the carbonisation of the process. Winding. Steve Swanson: This is the final process in carbon fiber production: winding. And this is the final product we send to Germany.
