Aluminum is in the nature of FSB
Machining and shaping aluminum has almost 100 years of tradition at FSB and is the heart of the company’s material culture. The resulting wealth of experience ensures unsurpassed quality from the melt to the finished product.
Gravity die casting
Door handles made of aluminum are cast by hand. The 660 degrees Celsius light metal is removed with the ladle and shaped using gravity die casting: the aluminum fills the shaping cavity solely by gravity.
Classic for the modern
The timeless beauty of the bronze inspired FSB to create fittings with their unique materiality. The copper-tin alloy used by FSB also impresses with excellent corrosion resistance, high tensile strength and great hardness.
Tools for tools to extend the hand
A special tool is used for each aluminum lever handle model. With over 50 different designs, the FSB range shines with a unique variety – from the classic by Johannes Potente to the angular and ergonomic model FSB 1185 by Andreas Heupel.
Man and machine lend a hand
Robots polish the geometric FSB door handle models. When it comes to sophisticated shapes or free-form surfaces, people’s sensitivity is required: Here, FSB continues to rely on manual work.
Lever handle blanks are vibrantly processed in trovalizing drums for several hours. This is where the accuracy of accuracy typical for FSB arises: radii and edges are carefully processed using small ceramic cones.
Beauty through use
Bronze fittings have become more radiant over the years by applying their typical patina. This patina has a special aesthetic appeal and testifies to individual use.
Internal high pressure forming (IHU)
The handles are “inflated” at 3000BAR. Some FSB lever handle models made of stainless steel are bent from pipe pieces. They are hydraulically formed over several stages – a technology perfected by FSB for the production of lever handles.
Bronze fittings are matted and then treated using a process specially designed by FSB. An immersion bath for copper-containing metals imitates the natural aging process of the material – the bronze-typical patina is created.
