Special machine engineering - in the highest-possibility quality

The development and implementation of special machinery require special skills. Ottemeier combines these skills with pragmatic creativity and flexibility. Utilising our own, from one source, development and design team and our own production facilities enables us to find the optimum technical manufacturing solution for every customer. Our machinery fleet is also well prepared for extreme requirements. Irrespective of whether this relates to extraordinary precision or extreme dimensions, whether machining special materials or particularly complex workpieces - the highest-possible quality is always guaranteed in every project stage. We can already assist our customers starting from the product development stage when requested. Core competences are the automated machining and processing of roll-form profiles and any kind of sheet metal machining. Our range of services also includes punching tables for hydraulically driven tools, special presses, stacking systems, drilling and milling plants, welding systems, robot cells and handling systems.

Special machines

You will find selected projects below which we have executed for our customers. We will be pleased to talk to you personally about additional work and projects.

Flexible CNC pre-punching plant

Flexible pre-punching plant with 18 punching units for utilisation in profiling plants

  • 6 pieces Size A
  • 6 pieces Size B
  • 3 pieces Size C
  • Coil widths up to 200mm

Shape punching plant

Up to ten tools are utilised to machine a steel frame, but not all tools are required at the same time due to the large number of product variants.


A wide variety of tools are utilised in the solution which we have developed. These include tools for punched holes for securing screws and bolts on the hinge side and opposite side of the frame, shaped punched holes in various sizes in the reveal, recesses with two fixing holes for the rating plate as well as oblique sealing holes in the area of the rubber sealing groove. A fully automatic rivet-setting station additionally places blind rivet nuts in the frame profile for the subsequent installation of an upper door closer.

Cutting plant for framework profile

Frame profiles made of composite materials are sawn to various lengths, provided with drill holes and subsequently cleaned after processing in the fully automatic production plant. A labelling system, a protective adhesive tape application system and a flame treatment system for surface optimisation are also integrated into the plant.

Trimming plant for sheet metal blanks

Sheet metal blanks for fire protection doors and fire protection flaps are trimmed on 4 sides in the fully automatic production plant. The sheets are picked up automatically, separated with a special system and then cut to the required size in a longitudinal and a lateral cutting station. The plant machines and processes blanks from batch size 1 in a large variety of variants. The finished blanks are automatically prepared for further machining and processing on bending and folding machines.


Travelling saw

Travelling saw for cutting foamed roller door profiles to length in a fully automatic production line with a production speed of up to 30 m/minute.

Concept stage and quotation

The customer and the close, personal exchange between them and our team are the core elements of Ottemeier's customer projects. Starting with the personal initial discussion and on to an intensive concept stage, the preparation and discussion of the quotation is implemented.

From order to the first production test

We commence with a kick-off meeting once the order has been issued – internally and with the customer. The development and construction stage then commences, the personal exchange remains a constant companion. The finished plant is initially assembled at Ottemeier and put into operation under production conditions. At the same time, initial training (plant operator and/or customer's maintenance technician) is executed and the pre-acceptance inspection.

Installation of the plant and after-sales service

The finished, already tested plant is then assembled on site at the customer's location and put into operation again under production conditions. The final acceptance inspection is still however not the conclusion for a project. Our after sales service and intensive support enables us to be there for our customers for as long as the plant still operates for them.
