Blanking and forming die for sheet metal no. 4

Technical guide

Die materials: steels, sintered materials and WIDIA

The life of a die depends above all on the materials of its active parts: certified tool steels are the foundation; special sintered steels and WIDIA (cemented carbide) inserts are used where wear is greatest, for example in high-speed dies, to extend cutting-edge life and reduce maintenance.

Quick answer

In brief

The life of a die depends above all on the materials of its active parts: certified tool steels are the foundation; special sintered steels and WIDIA (cemented carbide) inserts are used where wear is greatest, for example in high-speed dies, to extend cutting-edge life and reduce maintenance.

Certified steels

We use steels supplied by certified companies, with technical documentation for every product: metallographic analysis, hardness tests and ultrasonic non-destructive testing. Heat treatments and coatings are carried out by certified companies with an ACCREDIA-accredited testing laboratory.

When to use sintered steels and WIDIA

Tool steelsStructures and active parts for medium volumes
Sintered steelsActive parts subject to heavy wear, better toughness and homogeneity
WIDIA (cemented carbide)Cutting edges for high speeds and long runs, thin strip

Mistakes to avoid

  • Choosing the material on initial cost alone
  • Neglecting heat treatment
  • Using cemented carbide where the geometry does not allow it

How Cidonio Stampi works

Since 1969, we have been designing and building sheet metal dies in Rosà (VI): feasibility study with the customer, 3D CAD design, construction in our own toolroom and tryout with dimensional inspection. UNI EN ISO 9001:2015 certification by TÜV SÜD.

FAQs

Is WIDIA always worth it?

No: it pays off where wear is high, as in high-speed dies and long production runs.

How is steel quality verified?

Through documentation from the certified supplier: metallographic analysis, hardness and ultrasonic testing.
