RLP-HPL COATING

Stainless steel  
FE  
Alluminium  
Galvanized steel  

Rolleri RLP-HPL technology was designed to give a universal answer to the more traditional processes giving the tools a constant efficiency and performance at the highest levels.
The particular characteristics of this layer are the extraordinary tenacity (thanks to the introduction of the Carbon within the layer) and the ability to express itself at its best in different applications, and specifically on highly resistant materials, like Stainless Steel.
RLP-HPL coating achieves the highest levels of adherence, making even more cohesive the combination tool + coating.
The highly compact layer of RLP-HPL is able to express in its 3 microns thickness high hardness values that represent a solid barrier against wear ensuring extraordinary performance.
Furthermore, its structure “multilayer” is composed of several hundreds of different layers that give better control of structural stress.

RLP - Zinc Free COATING

Stainless steel  
FE  
Alluminium  
Galvanized steel  

Double coating Rolleri RLP-Zinc Free merges the already extraordinary performance of RLP-HPL, with self-lubricating and anti-adhesive layer based on MoS2 (Molybdenum Disulphide).
Developed in aerospace from the need to find an alternative to traditional lubricants, revealed excellent properties that have made him, as a result, very interesting for a variety of application fields.
This is a coating with a very low coefficient of friction, and it's able to release traces of wear lubricants (that is no abrasive particles are created by the wear of the coating).
When working on particularly rough surfaces, Rolleri RLP-Zinc Free gradually becomes smoother during use.
Due to these properties this treatment is particularly indicated not only to work with high resistance materials, but also for processing on galvanized sheet, aluminum or copper, because it is able to prevent "galling" process. RLP-Zinc Free can be easily re-coated.

ADDITIONAL OPTIONS

BACK TAPER ON THE SIDE OF THE PUNCH

This specification makes better performance for less touching area and less sticking material on the side face of punch body.

  • Without extra charge for round punches
  • +20% on shaped punches

EXTRA CHARGE FOR PUNCHES WITH DIMENSION < 1,5 mm

If the punch has a minimum size of less than 1.5 mm, consider a + 25% extra charge.
