Customer requirement

If you expect more then optimum quality from metal and sheet steel parts and if you are in need of deep draw parts and spun parts of the highest precision, GDH will meet your expectations:

We are your competent and innovative partner in metal processing.

Continuous investment in new technologies and further training provide the basis for high-quality and reliable work.

One qualified team is responsible for each one work step at GDH.

This ensures a constantly high quality also for special designs and small series.

Engineering

While many things change due to technological progress, one thing, however, will always count: Experience.

Especially in times of rapid technology development, experience, combined with a feel for it, is the decisive factor for first-class results.

Thanks to our vast knowledge from many years in the metal forming business, GDH is able to fulfill even special requirements.

From the realisation of your drafts up to the construction of the finished products - GDH will accompany you through every step of the process.

Especially where high draw ratios and re-drawing are required, you have a competent partner in us.

Engineering

We are utilising several CAD systems in 2D and 3D.

We fulfill your requirements while considering all aspects of forming technology and offer you an overall solution for your needs.

Profit from our know-how - we would be glad to set up a profitable project with you and help you optimise the manufacturing preparations.

Moreover we offer you an initial draw simulation in our works.

Profit from our experience and put your requirements into practice. We offer solutions for your ideas. Contact us!

Tool Manufacture

You are looking for intelligent tool solutions or you need to realise complex processing problems?

GDH offers you an overall solution: engineering and design, manufacturing of the individual components and construction of the finished tool.

Since 1992, GDH has been a competent partner for the design and manufacturing of sheet metal forming tools.

Our strength are deep-drawing tools, especially if re-draws are required.

We produce insertion tools, follow-on tools, composite tools and transfer tools, for prototypes as well as for series production up to a maximum weight of 10 tons.

Pressing Technology

Up to a pressing capacity of 120 tons from strip.

Up to 800 tons by insertion process

We producing in the field of steel, aluminium, high-grade steel, copper, brass and zinc.

Materials can be punched in thicknesses of 0.5 to 10 mm in optimum quality and at reasonable prices.

Deep-drawing Technology

We produce deep draw parts from any material that can be formed, like steel, stainless steel and non-ferrous metals.

We are able to process material of a thickness between 0.5 mm and 10 mm in a pressure range of up to 800 tons.

We can either take over your tools or produce them in our works.

Besides we can offer you an initial draw simulation in our premises.

Metal Spinning Technology

We produce spun parts from any material that can be formed such as copper, brass, steel, aluminium, stainless steel, zinc and tin.

Up to a blank diameter of 800 mm and at an initial sheet thickness of 6 mm for St, 4 mm for VA, 8 mm for CU/CnZu etc. and 10 mm for Al, rotationally symmetrical workpieces are produced by spinning.

We can either take over your tools or produce them in our works.

Laser Technology

We process in 2D technique, possible dimensions 3000 x 1500 mm.

Maximum thicknessVA up to 12 mm St up to 20 mm Al up to 6 mm

In 3D techniquepossible dimensions 3200 x 1525 x 600 mm.

Maximum thicknessVA up to 4 mm St up to 8 mm Al up to 3 mm

Pressure Vessel Components

We are certfied acc. to the quality assurance system for material suppliers as defined by EU directive 97/23/EG and AD 2000-Merkblatt W0 approved for pressure vessels.

We produce bottoms for pressure vessels and unpressurised vessels made of steel, stainless steel and aluminium up to a diameter of 1,000 mm and a wall thickness of 10 mm.

Surfaces and edges are processed according to your requirements.

Welding Engeneering

We are currently operating four welding machines for maximum unit weights of 250 kg, diameter 1,200 mm and surface dimensions 2,000 x 800 mm, 7 axes simultaneously.

Welding is done manually or by robot welding arms and using the following welding procedures:

WIG (Wolfram Inert Gas Welding) Especially for welding high alloy materials and for partly mechanical welding of aluminium and other non-ferrous metals.

MAG (Metal Active Gas Welding)Many assemblies and machines are made of structural steel. Their solidity depends on impeccable welding seams which are often genereated using the MAG welding procedure and the «appropriate» protective gas.

Mechanical Processing

In addition to the metal processing we offer this one to mechanical processing like lathing, wire-edm, grinding, cutting and milling.

Lathing:Maximum diameter 800 x3000 mm

Wire-EDM:Maximum finished dimensions 320 x 520 x200 mm

Mechanische Bearbeitung

Grinding:Maximum grinding area 1,000 x 700 mm, maximum height 575 mm

Cutting:With holding fixture maximum width 240 mm, maximum height 200 mmWithout holding fixture maximum width 420 mm, maximum height 410 mm

Milling:Finished dimensions maximum 3000 x 1200 x 1000 mm, unit weight maximum 5 tons

Innovation

Precision requires modern manufacturing technics, competence in all areas of production and not least most exact measuring and test procedures.

For initial models as well as during series production, strict quality controls and most recent 3-D measuring technics ensure the first-class quality of your products.

We are certified acc. to DIN EN ISO 9001:2000.

Zertifizierung

We are continually undergoing testing procedures in order to assure the first class quality of our products.We are certified in the following fields:

certified acc. to DIN EN ISO 9001:2000

TÜV approved material supplier acc. to EU directive 97/23/EG

TÜV approved for pressure vessels acc. to AD 2000-Merkblatt W0
