The Grohmann Group produces cast aluminium parts of top quality. At our Bisingen, Mühlacker, Schopfheim and Hirrlingen sites we manufacture cast parts using the chill casting and sand casting methods of production. We reliably supply customers from all sectors of industry (mechanical engineering, engine construction, the automotive sector, electrical and medical equipment, etc.).
Mechanical processing in our own facilities and with selected external partners enables us to satisfy industry’s desire for components that are ready to fit. Surface treatments of all kinds are the norm for the Grohmann Group.

Reuse of existing and proven machine tools up to complete production systems - through conversion, automation, overhaul, maintenance and relocation.

Industrial technology, mechanical engineering

GTK-Prototype UG was founded in 2014 by Tobias Günther and initially dealt with rapid prototyping machines.

Over the years, CNC milling and turning as well as assembly and development work were added due to customer requirements.

GTK-Prototype develops and designs on behalf of customers as well as internally using the most modern CAD systems such as Solid Works, Autodesk Inventor, Fusion 360 and others and inserts them into a comprehensive CAM system.
Through the production of prototypes in medical technology, mechanical engineering and the automotive sector, GTK-Prototype was able to acquire extensive experience in manufacturing.

In 2018, the production option laser cutting was added.

GTK-Prototype is currently based in Neuhausen near Tuttlingen and will move to the newly built company location in Radolfzell in the course of 2022.

Your competent partner in the field:

Turning - Milling - Grinding

Whether item or series production, we deliver the highest precision. Find out about our manufacturing capabilities, we can also solve your intended Zerspanungsproblem.

The company Günter Becker is in Osterode am Harz for over 30 years.
Until the early 70s, the main business focused on the development and production of automatic wire bending machines for electronic components such as resistors and transistors.

After introduction of semiconductor technology made the switch to using pure contract manufacturing in the field of turning, milling and grinding.
In this segment, we were not able to establish ourselves in the last southern Harz region through our quality work and numerous attract customers. For our customers today include well-known companies from all industries, including medical, aviation and aerospace technology, automotive industry.

We would be happy if we may this also includes you soon!

Engineering - Aluminium Casting - Machining - Assembling - Testing - Quality

Hama sets standards.
• Europe's leading supplier of electronics accessories with a unique breadth and depth of range
• around 18,000 items, from wall mounts, headphones, laptop bags and smartphone accessories to radios, fitness trackers and smart home solutions
• 3,000 new products every year by adapting the ranges to technological developments and new hardware
• in peak times, up to 10,000 packages are shipped daily (= 3,500 orders = 500,000 items)

Some of the products are automatically packed in Germany. A tool and fixture construction is integrated in the packaging area for the manufacture of the production tools. The machine park consists of a 5 acres processing center and a panel processing center.

Specializing in small technical parts, we have been manufacturing precise, high-quality injection molds and plastic parts with part weights from 0.01 to 100 grams from all common thermoplastics for 45 years now. The maximum shot weight is 246 grams.

Our philosophy is to convince customers through expertise, quality and performance.

We attach great importance to comprehensive customer service, value for money of our products, as well as absolute delivery reliability.

Long-standing and satisfied customers from the automotive, electronics, aviation, textile and medical equipment industries are proof of our company's successful strategy.

Example automotive industry

The manufacturing spectrum for the automotive industry ranges from mini and micro switch parts of various series, connectors, components for radio transmitters and wheel covers to coil bodies for ignition coils.

Example electrical industry
The delivery program for the electronics industry includes:

* Housing parts

* Light guides, diode holders

* LED holders

* LCD holders

Example medical technology

Extremely thin-walled components for welding housing halves, whose function requires absolute sealing against the surrounding atmosphere.

Example textile industry and model making

Spring holder systems, harness couplings, track rollers, roller bearings and completely assembled pulley units form an excerpt from our range of parts for the textile industry.

Couplings and coupling parts for model railroads represent an excerpt from our parts for model making.

Example Advanced Technologies

Automatic assembly of O-rings of different colors and dimensions on injection molded parts.

The integrated 100% inspection includes a query on the correct fit of the O-rings by means of light barriers, a color recognition, as well as a leak test by a vacuum pressure sensor.

Thin-wall technology

Extremely thin-walled components with wall thicknesses of less than 0.3 mm, with or without glass fiber reinforcement, which are used in medical technology, automotive engineering and the electronics industry.

The company was founded in 1949 by Hauke Walter Hauke sen. founded.

The company has set itself the target to process all kinds of metal. Made of iron, steel, stainless steel, aluminum, copper and brass welding complicated constructions and pipe bending constructions are made.

The material undergoes metal with us from the mechanical machining to surface treatment is a proven program. This production range assumes, of course highly qualified and motivated employees and a large, high-quality machinery.

Our company philosophy, "quality at a very reasonable price" has proven itself for over 50 years. Our customers, who are party to all industries, come from all over Germany.
