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.
