Hardly a car without us

OSSBERGER Plastics Technology is internationally established when it comes to the production of bellows for the automotive industry. The products manufactured on our machines are installed in almost all cars worldwide.



Then you have come to the right place.

The OSSBERGER PRESSBLOWER technology enables the production of bellows, shock absorber applications or axle boots with minimal tolerances. Our machines achieve excellent results in consistent reproducibility and are low-maintenance. The extreme precision of our process allows to save material and weight.

Our solutions



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









The type SB2-150, a version of the Pressblower injection blow moulder designed for bigger lot sizes, operates with two production stations. In addition, by optimizing motion sequences, the cycle time achieved by the previous model 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 injection moulding and blow moulding in one machine. The process is characterized by the achievement of exact connecting ends and perfect material distribution in the convolutes. 

First of all, the head part is injected, then the injection mould moves upwards, and a dosed quantity of plastic is extruded, forming thus a tubular parison that already has 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.

Hardly any car on earth can do without OSSBERGER products. In almost all cars produced worldwide there are bellows installed that were manufactured on OSSBERGER machines. The global market leadership is also a consequence of the cooperation with the internationally most important material manufacturers (see references of joint 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 tested for marketability tested. Currently, we are focusing on a new type of jounce bumpers for suspension struts, which together with the manufacturer DuPont is being developed to series production readiness. This innovative automobile application requires a high-precision production process, as guaranteed durably by Ossberger.

Did you know ...

stagecoaches reached an average speed of 3.4 km/h that at the end of the 18th century? To travel from Paris to Geneva, you had to plan 158 hours of travel time. In addition, the coaches jolted so much that "body and soul were in danger of getting separated". The automotive present is much more pleasing. Paris-Geneva can be reached in under five hours and without any jolting. This is also due to the pressblower injection blow moulding technology from OSSBERGER, which protects shock absorbers and drive joints.
