Hot die forging is the process of deforming a heated piece of non-ferrous metal between two dies. The latter are created in our very own tool shop, which is an integral part of the company. Specialising in the manufacture of made-to-order die-forged parts, we respond to each customer’s individual requirements for geometrically complex products. A combination of extensive expertise and complementary experience has allowed Prétat to make customised solutions its trademark.
Optional polishing and surface treatments
Integrated tooling solutions
Grain flow structure preserved
Mechanical properties improved
“Near net shape”, loss of material kept to a minimum
Optimised use of materials and machining time
With a thickness of 6.45 mm, Prétat achieves a precision of +/-0.05 mm. EN 586-3 prescribes a tolerance interval of between +0.5 and -0.35 mm. PRÉTAT’S ACCURACY IS 8.5 TIMES HIGHER THAN THE STANDARD REQUIRES.
The EN 586-3 standard allows a parting of 1mm in height (on a piece of 200mm length). PRÉTAT ALLOWS A PARTING OF JUST 0.1MM IN HEIGHT.
Faithful execution of shapes and forms, as illustrated by these letters with a length of 1.18mm, a width of 1.7mm and a height of 0.3mm.
This directional structure permits deliberate orientation of the given mechanical properties, first in the extrusion of bars, then in the material flow during deformation. The mechanical properties, enhanced by the grain flow structure, enable dimensions, weight, inertia and vibrations to be reduced.
