Patent Abstract

The continuous working lockless solid feed system has an extrusion press with a pressing tool that is connected to a gas pressure conducting connection strand for reactors. No leakage occurs over the component of the pressing tool that is provided with a rigid mold channel. The pressing tool has cooling channels around the pressing chamber. The mold channel has wear sleeves with mutually arranged geometry. The mold channel in the area of the extension has a microwave-transparent material that is pressure-resistant glass-, ceramic- or plastic material and integrates a microwave apparatus.
