DURO Series: Steel for precision molding

DURO Series: Steel for precision molding

The DURO Series features steel for highcapability molding with a highlevel balance of toughness and wear resistance that exceeds powder highspeed steel.

The DURO Series is suitable for fineblanking molds for materials which are difficult to process, for punches of fine, thin or complicated shapes, and for cold forging.

PROVA Series: Anti-corrosion steel for mirrored plastic molding

PROVA Series: Anti-corrosion steel for mirrored plastic molding

The PROVA Series features anti-corrosion steel for mirrored plastic molding. This special highgrade stainless steel was realized through new alloy design and our special melting technology. The steel is suitable for plasticforming molds.

The steel possess excellent resistance to corrosion and wear resistance and mirror polishability. It is suitable for molds used to form light guiding plates and aspheric lenses.
