Fin de Série et Pièces de Rechange
La production de volumes limités de pièces de rechange peut perturber même les calendriers de production les plus efficaces. Alors pourquoi fabriquer des pièces à faible volume dans une infrastructure à forte intensité de capital ? L’économie d’échelle dicte que les petits volumes doivent être produits dans un processus de production sans volume ou frais généraux abusifs. Les procédures rationalisées et condensées employées chez voestalpine Polynorm garantissent un prix de revient compétitif associé à une flexibilité maximale - tout en maintenant les hautes normes de qualité pour lesquelles la société est renommée. C’est le point fort de voestalpine Polynorm.
E-coating
In the Electro-Coating department, (assembled) car-bodyparts such as doors, bonnets and wings are pretreated and electro-coated in a fully automated dipping line. This line consist of a logistic system with different loading and unloading stations, a series of treatment baths (pretreatment and e-coat) and of course a curing oven.
At the loading stations the products are placed in frames with useful dimensions of l*w*h = 3.6*1.8*2.0 m. After scanning the unique product code, the frames are brought into the logistic system where 2 shuttles transport them to the paint installation. Because of the product code, the installation ‘knows’ what treatment the frame, and thus the product, needs. The frames are then transported by automatic cranes which lead them through the necessary baths.
Basically every frame can get a different pretreatment, a different coating layer or a different curing temperature. Most common is of course the traditional e-coat process which consists of a trication zinkphosphating, e-coat and curing oven. In this proces steel, galvanized steel and aluminium products are provided with a primer-coating layer which conforms to the highest automotive quality standards. Unique in this line is the flexible use of the conveying system. Because cranes are used, we have the possibility of running different programs. For example, we can give products a pretreatment only, which is used for etch passivating aluminium products as pretreatment for bonding. It is also possible to run the products only through the oven, for example for curing adhesives and sealers or for bakehardening aluminium or steel parts. After leaving the oven and cooling zone, the frames are again taken over by the logistic system where shuttles bring them to the unloading stations. Products are unloaded, controlled en packaged.
