Hardly any cars without us

OSSBERGER Plastics Technology is internationally established in the production of bellows for the automotive industry. Products made on our machines are installed in almost all cars worldwide.



Then you are with the right company.

The OSSBERGER PRESSBLOWER Techniques enable the production of bellows, shock absorber applications or boots with minimal tolerance ranges. Our machines achieve excellent results in consistent reproducibility and with low maintenance. The extreme precision of our procedure allows to save material and weight.

Our solutions



The PRESSBLOWER machines DSE 80, DSE 150 and DSE 260 are recognized in the market as solutions for the production of rotationally symmetric bellows. The machines stand out for their compliance with the smallest wall thickness tolerances as well as highest quality in series. Different product dimensions and weights can be realized on the respective machine types. 









Type SB2-150 is a version of the PRESSBLOWER Injection Blow Moulder, designed for bigger lot sizes. The machine works on two production stations at the same time. In addition, by optimizing the motion sequences the cycle times achieved by the previous type SB2/60 can be shortened. The attached switch cabinet reduces space requirements.

The process

The PRESSBLOWER process combines several techniques. It hosts the advantages of both the injection moulding and the blow moulding technique in one single machine. The process stands out by achieving exact connecting ends and perfect material distribution in the convolutes. 

First of all, the headpiece is injected, then the injection mould moves up, and a dosed quantity of plastic is extruded, forming thus a tubular parison with an exact wall thickness distribution. In the next step, the blow mould closes around the parison, blowing it to the desired form with compressed air.

There are hardly any cars on earth without OSSBERGER products. Almost all cars produced worldwide  contain bellows made on OSSBERGER machines. The global market leadership is also a consequence of the cooperation with the internationally most important material manufacturers (see references of common projects).

Development and innovation

Today's development is tomorrow's success. Ossberger is always committed to the testing of new applications. In doing so, we are the natural partner of the globally most important plastic manufacturers. In cooperation, new materials, new forms, new approaches are developed and their marketability tested. Currently, we are focusing on a new type of jounce bumpers for suspension struts, which together with the manufacturer DuPont are being developed up to series production. This innovative automobile application requires a high-precision production process, as durably guaranteed by Ossberger.

Did you know ...

that by the end of the 18th century stagecoaches reached an average speed of 3.4 km/h? From Paris to Geneva, travelers had to expect a journey of 158 hours. In addition, the coaches jolted so much that "heart and soul bore the risk of getting separated". The automotive present is much more pleasing. The trip from Paris to Geneva takes less than five hours, without any jolting. This is also due to OSSBERGER's PRESSBLOWER Injection Blow Moulding Techniques, protecting shock absorbers and constant velocity joints.
