Culobel

Besides deepdrawing, the construction of progressive dies is a specialty of Culobel. Progressive dies are designed to combine a number of processing steps, such as punching, deep-drawing and/or bending. This means that progressive dies are especially well-suited for the production of large series. They are utilized on high-speed presses and deliver a high output at a minimal cost.

With deep-drawing dies, hollow products are manufactured from flat metal plates. In a subtle process, the flat plate is pressed down and pulled over a specified mould. A good know-how of the tensile strength and stamping properties of the plate material are essential for this process.

Punching or cutting dies are especially developed for high-precision cutting or punching of a form out of a flat plate. Depending on the geometry of the required part, a single punch or progressive dies are used.

Bending dies are used for creating one or more folds in parts that have been punched out of metal plates (slugs). When bending is combined with more complex upsetting or elongation movements, then one speaks of forming dies.

For the assembly, control or post-processing of pressed parts, special holders (jigs) must usually be developed and constructed, which make this work possible or easier. Although such constructions are often relatively simple, the development of a good jig does require substantial research. The extent to which Culobel has developed and refined its techniques, has made the construction of jigs so simple that it can be done very quickly. The exceedingly short mounting time that is required, is combined with a high degree of precision.
