Deposition of wearproof and hardening, strengthening and antifrictional coatings on shaping die, punching dies, perforation dies and bender parts of stamps





Strengthening , wear proof and antifrictional coatings 


Coatings are deposited using of nanotechnologies.
Thickness of a coating 3-5 microns.
Preservation of a class of surface cleanliness.
Fine coupling with a basis (corresponding sublayers and preliminary ionic - plasma clearing of a surface).
Very high disseminating ability of used complex methods (an opportunity to cover blind hole, through apertures, carving, fretwork, etc.)
Coatings practically pore-free.

different coated dies

Strengthening, wearproof and antifrictional coatings on stamps and the cutting tool of various purpose 

Application strengthening, wearproof and antifrictional nannocompostie coatings on shaping parts of stamps (dies ) allows to solve the following problems:


  • Prolongation of service life.
  • Improvement of quality of a surface / edge of products.
  • Improvement of products removing from stamps.
  • Decrease in expenses for repair and restoration.
  • Replacement of galvanic coatings.
  • Reduction of charge cooling and lubrication liquids
  • Incresing number of reshapenings (due to decreasing wear of dies)

Stamp inserts with VPNf coatings



Our coatings show high efficiency of application on following types of the form-building tool:

Stamp cutting (perforation and punching dies) (recommended coating VPNM)

Especially effectively the coating works at cutting down of sheet metals: steels, a brass, copper. The wearproof coating on edges of a stamp carries out the same functions, as on mills at shock loadings. The coating protects products from tears during chiseling as even at deterioration the coating on a cutting edge is kept long time for adjoining surfaces of a matrix and a punch. Raises durability of a stamp in 3 and more times.

Stamp bending (recommended coating VPNM-f)

The coating on a bending stamp reduces friction of a made detail about a stamp. In this connection occurs more full shaping details, the opportunity of occurrence tears is excluded, the opportunity of "sticking" of a detail to a stamp is reduced.

Stamp beading, a stamp extrusion, draw plate (recommended coating VPNM-f)

As well as in a case with a bending stamp, decrease in friction between a processable detail and a working surface of a stamp (draw plates), and their simultaneous hardening essentially raises service life of a stamp and promotes reception of the better form of a product.


  VPN coated tools shows life increaesing on wide variety of machining centers punching and list processing equipment (Behrens, Trumatik, Amada, Schiavi, Rainer, Euromac, LVD, Finn Power)
