Wherever high-quality precision components are in demand, KÖCO is the right partner.
In close cooperation with our customers, the desired parts are developed to mass-production stage and then cold-forged on multiple-stage extruders according to the blueprints.
Mechanical finish, annealing and surface coating complete the service range.
No interruption of material fibres, but formation of fibres in line with the out- ward form!
Increased tensile strength, hardness and yield strength, depending on the degree of deformation
Compression and hardening of the material!
An increase in strength, depending on the degree of deformation, which opens up possibilities of using lower-cost, non-alloy steel as the basic material
Elimination of turning and drilling processes!
Close dimensional tolerances and excellent surface finish!
Subsequent surface treat ment minimized or dis pensed with
A shortcut from the idea to the finished product: Production of a stud on a four-stage extruder (set of consecutive steps)
Cylindrical blank cut to length
Extrusion of the smallest diameter
