Core competences

«We cannot be the best in every aspect. Therefore, we have positioned ourselves at the top where our core competences lie.»

Electrical Discharge Machining (EDM):
In 1969, we bought our first electrical discharge machine, which has been the foundation for our most important core capability. EDM very soon proved to be one of the promising new key technologies in metalworking. We have continually expanded our experience in die sinking and wire EDM and, these days, count ourselves amongst the leading contract manufacturers for precise metal machining. It is not the ten machines that we productively utilise every day that are getting us further, but the very high standards of our customers for surface quality and precision forming.
The advantages of EDM are: no mechanical stress to the metal piece, no limitations through hard metal grade or shape, high degree of machine autonomy, greater design possibilities at engineering level. Only an EDM-compatible design will profit from all EDM benefits – a piece of advice our customers will gladly follow.

Tungsten carbide working:
«It is the combination of knowledge of materials and knowledge of methods that form a basis for the skilled working of hard metal.»
We have managed to form a solid base to work tungsten carbide parts efficiently by liaising intensively with the outstanding tungsten carbide manufacturer Metzger Ltd, Lotzwil/Switzerland, and by meeting the very high standards of our customers. We support our customers when it comes to choosing the right hard metal and the most suitable methods such as grinding and abrasion, polishing and extrude-honing and also provide the handling during and after the production process.
Only perfectly manufactured hard metal parts will convince the customer to pay a higher unit price.

Laser Machining:
As with EDM, we decided early (1986) to go with this new key technology. We have been using the Nd:YAG pulsed laser (LASAG) for laser welding, cutting, drilling, marking and laser cladding. The high power pulse and high beam quality melt or vaporise nearly all known materials. Lasering is used to produce microstructures and to connect highly challenging geometrical shapes by conduction welding.

The same rules apply as for EDM: only a laser-compatible design will be able to take advantage of all the benefits laser technology has to offer.

Our Company

For nearly 70 years the company Gebr Unglaub + Co. GmbH produces metal goods. One year after the company was founded in Niefern at Pforzheim by the brothers Friedrich, Hans, Heinrich and Otto Unglaub already follows the company's first expansion by opening a branch operation in Zeutern in Bruchsal.

Business purpose of the two companies is the production of turned parts. In 1940, a tool and fixture is affiliated with Production machines for the production of cold forged parts. The company also established with this group of products on the market, so that the further diversification nothing stands in the way.

The establishment of a metal spinning and fabrication shop in your own home allow for the non-cutting shaping the extruded parts as a third product variant. The following years are the expansion and stabilization of the business, that is by using the latest technologies and well-trained professionals, for the production of parts of the highest quality and precision today.

Our objective is always to find solutions together with our customers to produce and, therefore, contribute to the creation of competitive advantage high quality products as part of an optimized production process.

Our program

Our production program includes:

* Technical extrusion and stamping parts
* Machines and CNC turned parts
* Paint Cups
* Tool and fixture manufacturing

... and of course everything with full-service brand Unglaub.

Our products

Wherever you can imagine the use of forged parts made of aluminum and copper, we can offer you solutions. We have a very high degree of vertical and are fixed with our products either on specific industries or specific applications. Our custom manufacturing in connection with the development and production of the necessary tools gives you the advantage to move parts of your problem-solving processes to us your suppliers and specialists in this field.

Take a look at our product range:

* CNC Turning * Fließpressteile * Filter * Color Cup * Pressure Vessels *

Also Turning we do NOT mass produced, but have moved us here on the production of high-precision parts according to DIN or factory standard. We work on almost all metal materials, including a variety of stainless steels.

Another field are our color cup and pressure vessels, which we can depending on the application in different sizes and both aluminum and stainless steel provide.
