Drawing dies & cones
More than 50 years’
experience
Ceratizit Italia SpA Italian plant in Alserio, Como, has been manufacturing tungsten
carbide dies for more than 50 years.
Produced at the site are standard profile drawing dies – round, hexagonal and square
– and special profile drawing dies, in addition to processing profiles based both on
drawings specifically requested by the customer or on internal developments, aimed at
solving the customer’s problems.
The entire production chain is performed on the spot, starting from the processing of
raw materials to the finishing of each item. Tungsten and cobalt powders are pressed
and treated according to specifications and processed through sintering furnaces;
a first check ensures the metallurgical suitability of the product.
At this point the outer and side parts are ground in order to enable the assembling
through shrinking-on of the cores into steel casings.
According to the type of geometric section required, the following step consists in the
internal grinding for diametrical profiles, while for shaped profiles the processing goes
on with spark electroerosion, where the complete internal profile is cut, to ensure that
the product geometry is up to the requested attributes.
All products marked Ceratizit are checked by the quality inspection staff, who verify in
detail all the dimensions, using modern and high-precision measuring instruments. It is
also possible, on request, to have a measurement report, certifying the product quality.
