Optimum Properties
with a flexible and modular approach that allows on-the-fly automatic changeover to different part diameters and heights, for optimum overall equipment effectiveness (OEE). The process begins with a servo-controlled decoiler that feeds stainless steel through a straightener into a proprietary trimming press. Here the material is sheared to the specified sheet lengths, and edges are prepared for laser welding.
German-based company accurapuls (with North American offices in Edmonton, Alberta, Canada) has developed the micro- cold-forging (MCF) process for improving the surface finish of dies and molds. Aimed at the automotive industry, the
