The pins that project into the screw flights are designed to break up the stream of rubber in the screw flights and facilitate intensive heat transfer and exchange of material. There will be constant temperature and flow distribution above the cross section. This will allow to process even very hard compounds or compounds otherwise difficult to extrude.

Degassing extruders are used to produce non-porous hoses or profile sections. Moisture or gas cavities in the rubber compound are effectively eliminated by the degassing unit such that the product can be vulcanized unpressurized.

These extruders are specifically designed to process silicone rubber. They are characterized by special screw geometries and coating, optimum cooling of the barrel and screw, feed designed for easy cleaning. This is the best choice if you want to produce profile sections or hoses from silicone rubber.

Gear pumps in combination with extruders

Gear pumps are used for products that require the smallest of tolerances or sensitive materials. Owing to the gear pump, the material can be fed with extremely low levels of pulsation and very gently. They can also be used to boost pressure such as it is required to fill molds, for example. These pumps can be attached to any extruder variant.

Feed roller with separate drive:

The feed roller can be equipped with a separate drive. In this instance, it will run at the desired fixed feed rate or it may be operated torque-controlled respectively. This may facilitate or enable respectively the feeding of problematical compounds.
