Mr. Dipl.-Ing. Frank Fuchs new vice president sales at ENTEX

We look forward to welcoming Mr. Frank Fuchs to our ranks. Since January 1st, 2020, Mr. Frank Fuchs has taken over the sales management at ENTEX. Mr. Fuchs has many years of experience in the international sales of laboratory extruders and measuring devices and will support us in expanding new sales structures.We look forward to a successful cooperation together!

 

 

Again asked...

In process engineering with planetary roller extruders, not only tempering and speed but also the type and design of exchangeable mechanical components of the process section have a serious influence on the behaviour of the extrusion mass. Design size of the extruder, overall length of the processing section, number, length and type of the used planetary spindles as well as the existing of dam rings between the roller cylinder modules and their inner diameter influence the melting and mixing behaviour of the mass as well as the dwell time, friction and heating behaviour. Of course, the physical properties of the raw material to be extruded, such as density, humidity, melting point, viscosity and temperature, as well as the degree of filling of the corresponding roller cylinder module also play a decisive role in the extrusion process.

In order to generate a stable extrusion process with consistently high product quality, a number of factors and influencing variables must be taken into account. If only one of the factors is changed, the extrusion result always will change too. Even the modification of small details, such as e.g. the inner diameter of an intermediate stop ring, the mixing ratio or the temperature of raw materials may have a serious influence on the quality of the product, especially for complex processes.

WPC (Wood-Plastic-Composites) are thermoplastically processable, recyclable composite materials made of different proportions of wood, e.g. wood flour or wood fibres, polymers and various additives.
The direct compounding of WPC with the planetary roller extruder is a continuous process. This processing method, which was specially developed for the production of WPC, allows a filler content (wood flour or wood fibres) up to 75%. With this process, WPC products with excellent quality and exceptional resistance can be produced. All the positive properties of wood as raw material are retained and supplemented by many other advantages. As a rule, all WPC components can be returned to the recycling cycle.

L-WE 30 - a new extruder generation for the laboratory scale

The modular extruder system of ENTEX has been complemented with the Pharma Laboratory Extruder of size 30. This means that the advantages of the planetary roller extruder - absolute temperature control and suitable mixing of active substances, low-shear thin-layer rolling-out, large surface exchange - can now also be applied in material-critical areas. With this, ENTEX allows now to process also material quantities of several hundred grams per hour.


Did you know that we have registered a new property right?

The ENTEX system is enriched by a further element – ERMO (degassing reaction module) is a world innovation that further enhances the efficiency and versatility of the ENTEX planetary roller extruder.
This latest addition to the modular system of ENTEX offers a significantly increased process chamber volume in comparison to the conventional cylinder assembly of the respective series.
It has been developed specifically for degassing applications. Here, free large-scale process surfaces and generously dimensioned flow cross-sections are decisive. ERMO maximizes these aspects without significantly changing the size of the extruder.
But the advantages of ERMO can also be used for the addition of fillers with particularly low bulk density – also here, the largest possible free cross sections are needed for the supply of such materials.
Another example of application are processes in the field of reactive extrusion. For their successful execution an extension of the dwell time or an enlargement of the reaction surface or of the volume are required.
Like all other components of the modular ENTEX system, several ERMOs can be used in series or at separate positions of a production line – in addition, there are various supplementary options such as side feeder, injection and degassing openings.
