Recubrimiento de punzones para mejorar el rendimiento

Hay numerosos recubrimientos disponibles para mejorar el rendimiento de la herramienta y mitigar los desafíos. Los recubrimientos pueden ayudar a reducir la fricción, el pegado, el desgaste y la corrosión, dando como resultado herramientas más duraderas con un mejor rendimiento.

Los siguientes recubrimientos se aplican internamente, con un impacto mínimo en el tiempo de entrega.
GALVANIC CHROME PLATING
A layer of hard chromium applied on a galvanic basis increases abrasion resistance and prevents the pressed powder from adhesion to the surface of the pressing punch. Moreover, it comprises a good anticorrosive cover.

PVD COATING
This is a vapor metal deposit process. Compared to the galvanic coating, the benefits of PVD coating are as follows:

  • better edge stability
  • contour preservation
  • wear protection

CRN CHROMIUM NITRIDE
The properties of CRN coating prevail over the properties of commonly used galvanic chrome plating, allowing for:

  • decreasing susceptibility to adhesion
  • an exceptionally homogenous structure and low density of pores
  • a very good price-quality ratio.

TIN OR TIAIN (TITANIUM NITRIDE OR ALUMINIUM NITRIDE)
With regard to their susceptibility to adhesion, they are comparable with CrN. Other advantages:

  • High tear and wear protection.
  • A smooth layer of low roughness.
  • Very high hardness.

DLC (DIAMOND LIKE CARBON)
Carbon-diamond shaped coating. A very resistant layer to abrasion. Gives long-lasting protection against adhesion. It is mainly used with products such as effervescent tablets and other difficult products.
