The Influence of different die geometries on the Extrusion Process of High-Consistency Silicone Rubber
(Society of Plastics Engineers, 2019)
Silicone Rubber and especially High-Consistency Silicone Rubber (=HCR), are typically processed in the extrusion process. Due to the high requirements in terms of the ma-terial properties and the geometric dimensions, a funda-mental knowledge of the whole process including experi-ences in tool design are essential.
In this study, HCR with different Shore-hardnesses are extruded on a vertical silicone extrusion line with various breaker plates with different length to diameter ratios (=L/D-ratio) in order to analyze ...

Pull and Foam - Injection moulding method: Foamed ribs for stiffening plane components
(Society of Plastics Engineers, 2012)
The pull and foam method is a foam injection moulding method which is currently being developed at the Institut für Werkstofftechnik (IfW) (Institute of Materials Engineering) at the University of Kassel. The processing principle represents an alternative to the existing foam injection moulding special procedures and introduces the possibility to partially foam a component. In so doing, thin-walled, hardly foamed components with foamed ribs can be made in one processing step, thus also components with graded ...

Assessment of the changeability of plastics processing systems
(Society of Plastics Engineers, 2014)
Changeable production systems are still being developed, especially in the field of plastics processing. Here, the assessment of the changeability is a decisive factor. This investigation deals with the assessment of the changeability of a modular pilot plant, and derives approaches for the further development of an evaluation system, as well as potential means to increase the changeability.

The Adhesion of LSR Thermoplastic Composites after Storage Tests
(Society of Plastics Engineers, 2017)
The adhesion properties of liquid silicone rubber (LSR) and different thermoplastics (PC, PA, and PP) were examined in this investigation. In order to guarantee the adhesion of both components, an activation (silicatization) of the TP surface, which is a conventional method, was carried out. Furthermore, the long-term stability of the silicatization (storage of the activated surfaces) as well as the wetting behavior were investigated. Moreover, microscopic investigations were performed to analyze the activated ...

The Effect of Injection Molding Parameters on Microcellular Foam Morphology
(2021)
Microcellular foam injection molding with physical blowing agent (MuCell®) delivers monetary benefits, processing advantages and freedom of product design by reducing shrinkage. In conjunction with an advanced mold technology, so-called Pull and Foam method, there is great potential in controlling the foam structure of the component locally. In this study, Polycarbonate (PC) components were produced with nearly compact outer skin and a closed cellular core. To understand the relation between processing parameters and ...

Formation of morphology as a function of process control by foam injection molding of a functionally graded component
(Society of Plastics Engineers, 2014)
A special mold technology enables the production of foam injection molded components with locally differing foaming ratios. Thus, components with functionally graded foam structures can be produced in one processing step. The method (pull and foam method) is based on the idea of creating components with thin-walled areas with a high surface quality and partially foamed, thick-walled areas (e.g. with the function of integrated structural elements) in a controlled foaming process. This paper describes the characteristics ...
