In 1961, Hubert Bulach in Baden-Württemberg Gammertingen the company Hubert Bulach, arts and crafts metal goods. Over the years, the company was restructured to supply work in the stamping and welding area. A consequent expansion was then 1986, the own tool and die making.

Meanwhile, the complete tube processing is possible.

Flexibility, reliability and high quality are the hallmarks of our company in the field of sheet metal and tube machining and tool making.

Punching - Bending - Pull

On several eccentric presses and hydraulic, CNC-controlled punching and stamping press with die cushion, we manufacture parts according to drawings, samples or customer with a press capacity to 200 tons and a clamping area of 1000x1200 mm.

Furthermore there is a controlled press brake for bending sheet metal parts up to 4mm thickness and 2000mm length.

Further processing such as surface treatment, welding, riveting and assembly to the finished part, we like to take over for you.

MIG - MAG & TIG

For precise and high-quality welds, a welding robot is used.

In addition, we have the possibility of producing welds on bends or angles bows with a controlled rotary welding table.

Bolts and spot welding operations are also carried out at us.

Rohrbiegetechnik

After drawing, sample or customer specification, we turn your pipes up to diameter 42x2mm and a length of 4 m on a CNC controlled pipe bending machine.
Further processing measures such as end form, punching or welding are also carried out by us.

Toolmaking

Tool designs in 2-D and 3-D area are created according to customer specifications, parts drawings or information from us.

All popular file formats can be read.
The connection of all machines to the CAD / CAM system allows for flexible and efficient manufacturing of tools.

- Drawing tools
- Follow-up and follow-on composite tools
- Punching tools for inlays
- Bending tools
- Tensioning, welding and testing
- Injection molds
- Foam molds

Wire and die-sinking EDM

We erode for you from item to small series.

Wire EDM
Sinking EDM

The tooling was founded in 1906 and currently employs 60 people. Focuses on the areas of tool and equipment, as well as contract manufacturing in the field of machining and EDM.

Our customer base spans virtually all areas of automotive, capital and consumer goods industry and includes many names that are at the forefront of the world market.

Construction
We design our tools in 3D mainly on Catia V5 from IBM. In addition, eligible for 2D and 5-axis machining Tebis and Cadda V4 used. The data is done with dial name or e-mail in the IGES formats 2 - and 3D, VDAFS, CATIA, DXF or DWG.

Toolmaking
* Follow-on composite tools
* Cutting and punching tools
* Bending Tools
* Stamping and pressing tools
* Foil cutting tools
* Foil deep drawing tools

We design and manufacture according to supplied designs presented or patterns, tools up to a size of 1200x4000 mm and a weight of max.25,000 kg.

State of the art production facilities make it possible to edit the design in 3D CNC-controlled production to initial sample inspection reports on 3D measuring machines, virtually any data and drawing documents.

Years of experience and a largely self-trained staff allows us to implement safe production of complex tasks in the situation.

Precise milling and wire EDM in air conditioned rooms give us the opportunity to manufacture cutting tools with an average gap of less than 10 microns.

In series production, we rely on machining centers manufactured by Heller with a pallet changer.
With speeds up to 16,000 min-1 and rapid traverses up to 90m/min and aluminum parts are to be machined economically

Jigs and fixtures
* Welding equipment
* Benders
* Drilling, milling and turning device
* Testers
* Handling Systems

Another mainstay is the manufacture of devices for the mechanical manufacturing, welding machining and measurement and testing tasks.

Certified welders ensure a stable basic structure, annealing furnaces for stress-free post-processing, and milling machines up to 5 axis for precise stop points in space. Modern 3-D coordinate measuring machines also help in free-form surface area to verify the accuracy measure to record and document.

Power spectrum

Toolmaking
Our clients benefit from our years of experience.

Through innovative tool concepts, the foundations for a low-cost production are laid.

Developed and adapted to the process technology of our customers, we manufacture tools and equipment for a process-safe production.
• pressing and hot pressing tools
• stamping tools
• laminating tools
• deep drawing tools
• Carpet-forming and Hinterschäumwerkzeuge
• Forming / composite tools
• Foaming
• Special tools

Mould
Based on over 30 years experience we offer our customers an increasingly sophisticated and cost-effective solutions.

Hullmann manufactures in Germany and France:
• Foaming for molded foams such as seat cushions and backrests
• foam molds for molded parts made of hard foam
• Mehrnutzenschäumwerkzeuge for moldings Together with the equipment manufacturers, we deliver our molds worldwide.

A team of engineers developed a convincing tool concepts for our customers.

Thanks to the simulation of manufacturing processes, we are able to provide our customers with engineered solutions.

The end of the manufacturing process, each mold is paid off in our laboratory to document next to the tightness of the finished part geometry, underlines the high quality of Hullmann.

Model
Models as decision support for designers are one of the first steps in our process chain.

Only models with a vehicle can be considered realistic.

Our machining centers enable us to be able to create complete cars in 1:1 scale. Whether cubing or auxiliary models for tool and mold making, the traditional team of model builders is one of the pillars of Hullmann.

In model manufactured by Hullmann:
• Working models for mold
• Casting models
• Teach (Prüflehrenbau)
• Waterjetschalten


Jigs and fixtures
For the completion of individual process steps are often independent of the core process of working, used functional facilities.
Whether Hochpräzisionsbohrvorrichtungen for aircraft construction or installation and / or Komplettiereinrichtungen for the automotive industry. The necessary devices are realized by the configuration according to customer specification, through to operational handover of Hullmann.

Examples: devices ...
• ... for the assembly and joining of different, belonging together components in the grille assembly.
• ... for the insertion and braces retainers in the vehicle floor carpets
• ... for the production of a component following converting, to produce variants (RL / LL or gasoline / diesel) of a basic component

Punch presses and thrusters
Specially designed for use in conjunction with Hullmann punching and forming a lighter and less expensive pressure transducer was developed.

The hydraulic control of the pressure transducer is designed for safe press control with safety block and monitored valves and follows the latest UV and VBG regulations.The CE marking and the corresponding Declaration of Conformity is self-

The machine base is strong even in the basic version. In addition to a light curtain on the operating side of the pressure transducer and sitema clamping heads for safety and comfort during operation, the control system is constructed on the basis of a PLC SIEMENS S7. It can be completed on request with different visualizations in the add-on package.

What sets us apart in particular are our fundamental values — reliability, flexibility and loyalty. These values are the backbone of our company and are reflected in every project we take on. Reliability is the foundation of our work, as we keep our word and our promises. Flexibility is our strength, as we adapt to the individual requirements of our customers and always find tailor-made solutions. And loyalty shapes our relationships — whether with our customers or within our team.
