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.
