Sheet metal forming
Minifaber is a company specialized in sheet metal forming, processing both large and small quantities of metal. We are driven by passion and oriented to the continuous innovation and upgrade of the technical processes we carry out. These values, added to our experience and know-how, brought us to work with the best companies in many fields, such as professional lighting, electromechanics, home appliance, medical, logistics and equipment industries.
Sheet metal forming process
There are 2 types of sheet metal forming: hot and cold. Minifaber specializes in cold metal forming, which offers important advantages.
But why do we say "cold metalworking"? The term "cold" does not indicate the absolute temperature of the metal; it refers to the value given by the ratio between the processed metal melting temperature and the temperature at which the processing is carried out. If the ratio is less than 0.3 °, processing is said “cold”.
The metal forming process consists in working the sheet metal without removing any material: the sheet metal is positioned on the mould and, there, processed according to requirements (blanking, drawing, bending, punching).
Advantages of cold metal forming
- Excellent mechanical characteristics of the finished product, because cold metal forming does not involve structural changes in the metal
- Reduction of processing times, i.e. it is possible to obtain a finished product with great speed
- Material savings
- Reduction of production costs
Sheet metal forming tools and machines
The main tools for metal molding are presses and moulds: the play between the press and the mould transfers the stress of shearing or deformation on the sheet.
In Minifaber we also produce the moulds; in particular we are able to design, prototype and construct 4 different types of moulds:
- Drawing and blanking moulds
- Progressive (or step) moulds
- Shooting moulds
- Transfer moulds.
Sheet metal forming applications
Sheet metal forming is used in almost every sector of industrial production; these are the main industries we work for, realizing both components both finished and complex products (such as lighting systems, kitchen robots or vending machines):
- Automotive industry
(e.g. doors, hoods, fenders)
- Home appliance industry
(e.g. food processors, cooker hoods, freezers)
- Food industry
(e.g. cooking pots, vending machines’ bodies and internal parts)
- Medical equipment industry (e.g. pressurised steam steriliser,
- Plant building ( e.g. gas valves, voltage switches, switch gears, control shafts and switchboard components)
- Professional lighting engineering
