The metal stamping process is a technique used in the metallurgy industry to deform a flat metal sheet into a three-dimensional shape.

Everything you need to know about the stainless-steel stamping process

Deep drawing is an industrial process that consists of giving volume by deforming the material without heating, i.e., metal sheets, with tools and dies, and is part of the metal forming and transformation techniques (assembly, drawing, rolling, bending, stamping, metal sheet work, etc.). This technique is used to manufacture small, medium and large series in industry, and in many sectors of activity: whether to manufacture small metal parts or large parts such as the side of a vehicle for example.

In order to deform the metal parts without breaking, powerful mechanical or hydraulic presses are required, with more or less slow stamping speeds. The greater the deformation, the more precise the stamping tools must be and the slower the press must work to avoid breaking stainless steel. The machines are hydraulic presses, which have a power of several tens or even hundreds of kg of force, up to thousands of tons. For this manufacturing process, the metal sheets (stainless steel, aluminium, copper, brass, alloys) are clamped between a punch (punching) and a die, in order to deform without breaking when the punch and the die advance, in opposite directions.

Stamping consists of the progressive deformation of a metal sheet, or a strip of metal, i.e., a cut-out piece of metal that suits the shape of the tooling used. Stamping, another metal deformation technique, consists of moving a volume by "printing" to the metal, by instantaneous static striking, either cold or hot. It is also known as forging in the industrial context of steel.

Stainless steel stamping at Stellinox

At Stellinox company, manufacturing in France, there are 6 hydraulic presses with a capacity of up to 250 tones, for the production and manufacturing of medium-sized stainless-steel parts. Stellinox owns tooling and dies for each model of part manufactured. The manufacture of a plate to be stamped begins with the design of a mould.

Stellinox stamps trays and plates with a depth of up to 11 cm. At this level of deformation of the steel sheet, the process is very slow so that the metal is stretched without breaking. On the stamped parts you can see very clearly on the outside where the metal has been drawn. The sheet, which was rectangular from the start, is deformed. It is now time to move on to the stamping or cutting phase, which is carried out on mechanical presses (cutting machines) or by laser cutting.

Stellinox also carries out punching operations, which consist in cutting steel strips using special tools.

Stellinox, which has experience in stamping since , is your supplier for the production of quality products made in France for all your stainless-steel dish models.

Benefits of stainless steel

With its lustrous reputation, stainless steel brings many benefits that make it a preferred material in countless applications. Its corrosion resistance is at the heart of its appeal&#;a hallmark feature that ensures longevity and durability in harsh environments. This resilience makes stainless steel an ideal candidate for food processing, medical devices, and marine applications, where exposure to corrosive elements is a daily challenge.

Another significant advantage is its strength-to-weight advantage. Despite being strong and durable, stainless steel can be surprisingly light compared to other metals. This property is precious in the automotive and aerospace industries, where every gram counts.

Hygiene is yet another area where stainless steel shines. Its non-porous surface does not harbor bacteria or pathogens, making it the gold standard for medical equipment, kitchen utensils, and food processing plants. This easy-to-clean material meets the strict sanitation standards required in these sectors.

Furthermore, stainless steel is aesthetically versatile. It can be finished in various ways&#;from a mirror-like polish to a matte finish&#;allowing designers and architects to incorporate it into functional and decorative elements.

Lastly, the sustainability of stainless steel must be considered. It is 100% recyclable without degradation, contributing to a circular economy and reducing the environmental impact of new product manufacturing.
