GEERTS-MATERIAAL

Deep drawing and forming of copper, aluminium, steel, stainless steel, brass and titanium

Copper

With copper, it is possible to also manufacture asymmetrical forms with deep drawing. The soft material makes annealing unnecessary. Geerts can deep draw copper with a maximum thickness of 5 mm.

Copper finishing done by Geerts:

  • Degreasing
  • Tinning
  • Grinding/polishing
  • Coating
  • Lacquering

Aluminium

This type of material is perfect for deep drawing. However, it does require some effort to achieve a good product. With the proper choice of base material and the research that we have done with deep drawing of aluminium, we know the limits. With aluminium products manufactured by deep drawing, there is no need for annealing. Aluminium can be deep-drawn at Geerts to a thickness of 5 mm.

Finishing of aluminium:

  • Degreasing
  • Anodisation
  • Chromating
  • Powder coating
  • Tinning

Stainless steel

Stainless steel (and not rust-free as often indicated) is one of the hardest materials for deep drawing. Because of its extensive experience with this material, Geerts is unrivalled in its ability to manufacture excellent products. As a result of the tension generated in the material during the deep drawing, annealing is often required. Geerts can do deep drawing on stainless steel to a maximum of 3 mm.

Finishing of stainless steel:

  • Degreasing
  • Grinding
  • Pickling and passivation
  • Electro-polishing
  • Coating

Titanium

Titanium is a material with which beautiful products in all kinds of shapes can be deep drawn. The material has many advantages such as the weight, which is for example several times lighter than stainless steel. Other benefits of titanium are the corrosion resistance and the strength of the material. Titanium is used frequently in among others the food industry due to the neutral influence on scent and taste. Geerts can deep draw titanium with a gauge of 2 mm.

Steel and coated steels (galvanized, tinted, varnished, aluminised etc.)

These materials are particularly suitable for deep drawing and forming. All kinds of forms are possible. The material doesn’t have to be annealed. Steel (types) can be deep-drawn at Geerts to a thickness of 8 mm.

Finishing of steel:

  • Powder coating
  • Grinding
  • Tinning
  • Galvanizing

Brass

Brass is also particularly suitable for deep-drawing of various forms. From simple to complex. Annealing is necessary with some brass products, but the material itself does not call for this. Geerts can deep-draw brass to a thickness of 5 mm.

Finishing of brass:

  • Degreasing
  • Tinning
  • Grinding/polishing
  • Coating
  • Lacquering

 

Apart from sheet material, deep drawing can also be done with modified materials, like perforated, brushed or smoothed materials.
