In every device used today, from cars to household appliances, springs provide functions that make our lives easier without being visible to the user.
b&m customers are companies from all industries – but mainly automotive and supply industry;
Our area of operations include wire and metal sheet springs;
The used materials are according to standards of the automotive industry;
Processed are spring steel wire and spring band steel according to DIN EN 10270-1 DIN EN 10270-2 and DIN EN 10270-3 as well as iron, non-ferrous metals as copper, bronze, CuBe, Ms and special materials
Key aspects are quality, functional requirements and cost efficiency;
According to requirements (sunroof, seat or auxiliary heating system, etc.) shape, material and surface can vary.
Compression springs
Spring geometry can be cylindrical, conical or barrel-shaped;
Compression springs are made from round or square shaped wire;
Closed, or closed and ground spring ends;
Wire diameter: from 0.1mm – 5.0mm.
Tension springs
Tension springs usually have a cylindrical form;
Eyes according to the standard DIN 2097 but also special eyes are possible;
Tension springs are made from round shaped wire;
Wire diameter: from 0.1mm – 5.0mm.
Torsional springs / Moulded wire parts
The spring geometry is adjusted depending on the area of application;
Spring loading occurs by torsion around the axial direction;
Torsion springs are made from round or square shaped wire;
Wire diameter: from 0.1mm – 5.0mm.
Shaped springs
The shape of the spring is developed depending on the area of application;
Shaped springs are made from spring band steel;
Sheet metal: from 0.1 mm – 3.0 mm.
