Tension springs

Tension springs

Tension spring is a spring which works in extension; it is also characterized by the presence of eyelets, made out of coils or linked to the spring’s body as a hook. MOLLIFICIO PAVANO SPA has been manufacturing tension springs since 1955, and therefore its customers can count on necessary experience, technical knowledge and productive skills in products’ development.

Spring’s production is preceded by a meticulous preliminary project, a careful raw material’s selection and testing, that must respect technical specifications and applications required by customer. Modern and large productive plants allow to satisfy different types of demand, from industrial series to small and prototypes production.

Wire bending range:
from 0,20 up to 20,00mm
Eyelets typologies available:
- simple and double English hooks;
- German hooks;
- open or closed hooks;
- shaped hooks according to drawing;
- moulded hooks.
Superficial treatments:
according to customer’s technical requirement
Main Application Markets:
- furniture and upholstery;
- automotive;

Metal wares in wire and strip-rings Metal wares in wire and strip-rings

Metal wares in wire and strip-rings

We name METAL WARES all those shapes produced by bending round or squared material, basing on a drawing, prototype or on research made for our Customers itself.

Our Company, born as a Spring manufacturer, has enlarged its production possibilities with wire forming manufacturing of round and strip material as a natural evolution of original production.
The production line of METAL WARES has numerous applications: a bend shape can be find everywhere in today life, but only few Companies can produce it professionally, using different materials, and providing a wide range of finishings and superficial treatments as MOLLIFICIO PAVANO SPA does.
Thanks to our plants we can produce either small quantities and industrial series.

Production of springs, pruductive process and quality

The presence of highly skilled personnel allows MOLLIFICIO PAVANO SPA to follow step by step all the phasis of the productive process:

- development, project and realization of tools and plants are internally possible thanks to the use of modern informatic systems and CAD-CAM;
- sourcing of raw materials is made with the support of selecting systems and suppliers’ grading; realization of bend parts on costumer’s drawing is specially studied with and for the customer itself.

MOLLIFICIO PAVANO SPA operates according to the rules written in the Internal Quality Handbook, based on UNI EN ISO 9001-2000 Standards. Raw material in entrance is tested according to above standards, granting production uniformity and homogeneity. Production lots are also tested by skilled personal with the support of modern testing units. Quality Office is at customer’s disposal to convey personalized testing procedures. Tracing of all production lots is granted by the internal testing system and by labelling.

Heat treatment of springs and superficial treatment of springs

Heat treatment and temperature release are made inside MOLLIFICIO PAVANO SPA, after spring’s coiling, by modern plants, appositly developed and manufactured. In order to satisfy customers’ diversified demand, springs and metal wares can be submitted to different superficial treatments such as:
