Deharde-Maschinenbau H. Hoffmann GmbH is a soundly established company in the metalworking industry with a workforce of over 150. The production of jigs and fixtures - as well as the construction of sophisticated high speed and low speed wind tunnel models - represents our particular fields of specialisation as contract manufacturers. Our scope of activities is traditionally very broad and also includes the construction of special-purpose machines and moulds.

Manufacturers of aluminium coil and sheet ranging from Cold Rolled Products 1xxx, 3xxx, 8xxx, in Hardness degree 0, H14, H18, H24 ranging in thicknesses of between 0.20mm to 10mm. The width can be anything from 200mm to 2200 mm.
Continuous Casting coils are also available in 1xxx, 3xxx and 8xxx in Hardness degree 0, H14, H18, H24 available in thicknesses of 0.20 mm to 10 mm and in widths of 20mm to 1700 mm. The roll inner diameter is 610 mm and the roll outer diameter is 2200 mm.
Detal Aluminium LLC is a leading manufacturer in the non ferrous industry that produces aluminium oxide, primary aluminium and semi final aluminium products such as aluminium sheets and coils. For 2014 our production capacity is 100,000 tons of aluminium.
We export 90% of our capacity throughout the world.

DIAG is a manufacturer of aluminum die casting in all common alloys.
Casting weights of up to 30 Kg 5Gramm are möglich.Bei appropriate customer
We can also edit the castings and finish surfaces.
As another we can create all the necessary tools in their own mold.

We manufacture since 1938 metal products for technical uses, punched, laser cut, bent, bent, deep drawn, pressed, drilled, threaded, countersunk hardened. Our range includes filter screens with or without borders, disc springs, washers, saddle washers, high precision shims, complicated shapes (with or without bends or deep trains) with total or consequential cuts, etc.



We have not formed a department for surface treatments, but thanks to good relations with relevant specialist firms also get this.



Punched parts made of all metal or of plastic sheets such as nylon, Teflon, insulation, polyester film, fiber, PVC, laminated paper, pressboard, etc. belong to our product range. Thanks to a large stock of raw materials, with more than 1,300 different varieties or thicknesses we can deliver at very short notice.



The tools required for our manufacturing are produced in our own tool shop.We can advise you when planning or designing a part, in order to develop the most economical solution.
Our specialty: R total - in the quality design, concentric and flat, of any material suitable for punching, even small series. General Tolerances: + / - 0.05mm. Since we make mostly non-standardized rings according to the special requirements of our customers, we do not hold the finished goods warehouse.



Your advantage: It is worthwhile to consider whether twisted washers could be replaced by punched in every respect. In addition to pricing advantages, the choice of material is particularly less concentrated towards higher strength and corrosion resistance.



Our viewable and downloadable here (HTML table) tool list (see website) will show you our facilities. This tools not included can be produced at short notice and with excessive costs due to the internal normalization.



Ask us.

The list (see homepage) contains the existing complete sections that are constantly updated. Moreover, we have for cases where the preparation of a complete section due to small numbers does not justify a large number of simple circular cuts.
These can be for diameters over 50 mm within the substance is technically possible in two passes, ie outer and inner diameter punched separately while maintaining concentricity, combine arbitrary. This with a tolerance of + /-0.1mm. Another reason to ask us!



Further manufacturing opportunities exist for smaller series from 120 - 1200 mm diameter at a max. Material thickness of 3 mm (circular shear).

We are an export company working with reliable manufacturers and suppliers. We supply mechanical equipments as per drawing or technical specs
