SHOT-PEENING
It is a process of projecting micro steel balls onto the surface of the spring. These surface stresses will improve the service life.
SPRING
An elastic member capable of withstanding large deformations and intended to exert a force tending to return to its original shape after being bent, stretched, compressed or twisted.
(The springs are intended to cushion shocks [buffers, suspension springs of cars] by absorbing energy to produce a movement [clockwork] by restoring the energy stored during the deformation.)

SURFACE TREATMENT
The default steel springs are oiled.
We offer all types of surface treatments to protect the springs (zinc plating, chromium plating, burnishing, copper plating, cadmium plating, cataphoresis, Delta Tone, Delta Protekt, Deltaflon, pickling, epoxy, tinning, chemical nickel, painting, phosphating ...)
