The more concrete the better, since your ideas can only be tested under real conditions when they take shape. In order to do this well, inexpensively and quickly, our sample production department is available. Depending of the quantities and requirements, a variety of processes are used for sample production:
For individual sheets:
CO2 slab laser and fibre laser with max. cutting area of 1,250 x 2,500 mm
ND:YAG solid state and diode lasers with outputs of up to 1 KW for high precision welding work
We can also manufacture auxiliary stamping tools for samples and prototypes. The properties of the parts manufactured with these match the later standard parts.
We manufacture part-specific packaging and holding devices for packages in welded, riveted or baked forms.
