Gear pump technology opens new possibilities

Fine Mesh Straining within the Mixing-Line

Fine mesh straining with gear extruders developed especially for the straining of rubber compound, the roll-ex gear pump strainer from Uth ensures a low temperature increase under high pressure. With throughputs up to 10.000 kg/h the gear pump extruders are a particularly good choice for the operation in mixing-lines for different mixing stages. more...

Silica-Hollow-Body

Development of an Extrusion for the Continuous Pre-Cross-Linking of Solid Silicone Rubber

The blow molding of solid silicone rubbers is possible with a defined pre-cross-linking of the material. The pre-cross-linking allows the extrusion of the parison without strong drawdown and the forming with compressed air into a hollow body. The objective of this contribution is the development of an extrusion die for the continuous pre-cross-linking of silicone […] more...

Analysis of the Efficiency of continuous Vulcanisation Processes

As shown in lab-scale investigations on continuous vulcanisation processes show, that various forms of vulcanisation energy transfer have very different energy demands and deliver material-specific different vulcanisation results and properties. In order to enhance basic knowledge on influential factors on continuous vulcanisation processes, a research is conducted on material-specific ideal vulcanising strategies using a specially […] more...
