The technological and economic benefits of the so-called precision cold forging process can be found in the low-cost, precise blanks obtained that minimize the finishing stages (cutting to length and grinding the external diameter).
In addition, this technology enables the pistons to be substantially lightened by using walls of variable thickness where the thickness is increased only at the neck of the seal.
Recommended material grades: non-alloy low-carbon steels.
Methods of production:
- Forge: using horizontal multistation cold presses.
GÉVELOT EXTRUSION, drawing on more than 40 years of experience in this family of products, is able to offer a level of quality that fulfils the safety requirements for these products.
