You know this?

Are you still using hammer assembly?

Is the vehicle leaking or damaged due to incorrect assembly?

The assembly speed is too low?

Is the profile seal falling off the flange?

Are you looking for a roll-on device that fixes profile seals quickly and reliably?

Do you already know the Multiformer®?

  • Even assembly due to automatically equalising shaft spacing

  • Maximum result due to precise adjustment to the assembly situation

  • Infinitely variable speed

  • Small drive-through width due to compact drive technology

  • Numerous variants due to modular design

Economic Rollforming. Try it out!

Let's work together to get the most out of the roll forming process.

The advantages

  • The Multiformer® adapts to the assembly situation

  • Different sheet flange thicknesses are automatically equalised

  • The contact pressure of the bending rollers is infinitely adjustable via the built-in pressure regulator

  • The contact force is uniform even with different shaft spacing

  • The contact force is controlled by checking the working pressure

  • Pneumatic opening and closing of the press-on head by actuating the hand lever

  • The drive starts and stops when the hand lever is operated

  • Easy handling by operating the hand lever as the only operating element

  • The Multiformer® is equipped with a strikingly narrow gear housing

     

Consistent assembly quality!

The Multiformer® covers flange thicknesses from 2 to 7 mm in daily series production. In individual cases, even larger ranges of 4 to 12 mm are covered.

Cross mounting possible

With similar profile cross-sections and mounting situations, the Multiformer® can enable cross-mounting on a line, even with different vehicles.

Reduction of assembly time!

There are assembly situations in which speeds of up to 600 mm/s can be achieved.

Long service life & reliability

Long-term 24/7 use with very low maintenance is our quality standard!

Our Multiformer® opens up new possibilities for you, regardless of the type of roll forming seal.

The Multiformer® was developed by us to produce profile seals in the automotive...

  • on different sheet metal flange thicknesses
  • with anti-friction coated surfaces
  • with sensitive cover lips
  • with large sealing hoses

... to be able to assemble economically with high quality.

We are happy to advise you with our experience!

Erodiertechnik & Werkzeugbau Siegfried-W. Grunwald e.K.

Since 1986, Mr. Grunwald and part of his team have been able to draw on extensive experience in the field of rubber profile production at ContiTech Profile GmbH, a division of Continental Gummi-Werke AG in Hanover:

These experiences range from the design and manufacture of extrusion tools to profile development, process engineering and the running-in of tools under production conditions.

This was followed from 1995 by the optimization and manufacture of ContiTech rollforming devices and their worldwide distribution.

At the same time, the company Erodiertechnik & Werkzeugbau has been active in the field of tool and fixture construction since its foundation in 1992. Over the years, we have received countless orders from the rubber processing industry.

Our patent-protected in-house development, the Multiformer®, has become our key business since its market launch in 2003, and we are proud to supply national and international automotive manufacturers.

Thanks to a selected machine constellation and excellently trained employees, we achieve a very high vertical range of manufacture from the idea to the prototype to the series part.

May we also convince you of the advantages of the Multiformer®?
