A specific coating carbide punches and dies, which creates a barrier between the material and the tooling, is a solution for operations in which the material being compressed is sticky, corrosive, rough or otherwise difficult to use.

This article will review the various coatings for punch tips choices available at SundiTools Compacting as well as the common applications of each coating. The goal is to help customers make more informed decisions when selecting the right tooling.

SundiTools Compacting provides the option of a Punch Tip coating

SundiTools Compacting offers five different options for punch tip coating to meet the requirements of the customer:

Hard chrome plating: Hard Chrome plating coatings increase the corrosion resistance and wear resistance of the tooling, and reduce product friction and adhesion.

PVD-chrome coatings offer better wear resistance, better adhesion properties, and better corrosion resistance that FSG-HCP coatings do not.

Chrome nitride: These coatings have the highest corrosion resistance, extremely good adhesion properties, and good wear resistance.

Titanium Nitride: Titanium Nitride coatings exhibit high abrasion wear resistance as well as superior adhesion properties than FSG-HCP coatings.

Titanium aluminum nitride Titanium aluminum nitride coatings have the highest wear resistance.

The application of punch tip coatings

The most suitable coating to put on the edge of a punched tip is determined by the characteristics of the material used for tableting. For instance:

Hard chrome plating coatings are ideal for tooling used on slightly hard, corrosive, or sticky substances.

For tooling on mediumly abrasive or corrosive materials, PVD-chrome coatings can be used.

Chrome nitride coatings are suitable for tooling used on extremely corrosive, highly sticky, or moderately abrasive materials.

Titanium Nitride coatings are ideal for tooling used on highly aggressive and corrosive substances.

For the purpose of tooling on extremely abrasive materials such as crystal powders and titanium aluminum nitride is the ideal choice.
