Development of a Radian Friction Welding Machine Using the Circular Process with Limited Rotational Motion
(Society of Plastics Engineers, 2013)
The processing-technological limitations of components which can not be continuously rotated, either due to their length or marginal protrusions, make the realization of several potential applications using rotation welding unthinkable. The difficulties that arise while generating a high quality weld and are caused by large component tolerances and component warping are known. In order to extend the potential of friction welding, it is necessary to develop a new welding technology. In cooperation with Fischer ...

Hybrid composite materials made of polypropylene with wood and polyethylene terephthalate fibers
(Society of Plastics Engineers, 2014)
We aim to manufacture injection molded components which consist of thermoplastics reinforced with fibers and which have improved properties (high strength and high notched impact strength). Thus, we intend to access new application fields for the not readily visible area of the automobile interior.

Characterizing the Rheological Behavior of Liquid Silicone Rubber Using a High Pressure Capillary Rheometer
(Society of Plastics Engineers, 2016)
The injection molding process of liquid silicone rubber (LSR) imposes high demands on the injection molding machines and the tools due to the low viscosity of silicone rubber. There is very little data which describes the rheological behavior of LSR and its influencing factors across a range of shear rates.
In this study, the rheological behaviors of different types of LSR were characterized using a high pressure capillary rheometer with an apparent shear rate that ranged from 350 to 4000 1/s. In order to identify ...

Multicomponent Injection Molding Of Thermoplastics And Liquid Silicone Rubber (LSR) – Either Cured By Heat Or UV Light
(Society of Plastics Engineers, 2016)
For processing thermally curing liquid silicone rubber (LSR) as well as UV light curing LSR for multicompo-nent injection molding with thermoplastics in an compa-rable way a processing center was designed and set into operation.
For the production of the multicomponent specimens a modular tool was designed. In there a thermoplastic plate gets molded on the one side, then gets transferred auto-matically by a robot system and gets overmolded by the silicone on the other side. The complete silicone side of the tool is ...
