Process media for forming technology.

BECHEM products are applied all over the world when the shape of metals is changed in cold or hot sheet forming, wire and tube drawing, massive and cold forming processes. In liquid or solid, oil, soapy or aqueous form they minimise friction between tool or die and metal, even in case of extreme forming degrees and surface pressures. BECHEM plays a key role in the manufacture of semi-finished and finished products of high precision and optimal surface quality, ready for their intended application or for finishing purposes in subsequent processes.
