Extruder Technology

Range of competency and services

Design and dimensioning of single-screw extruders according to customer-specific requirements taking into account the plastic granulate to be processed:

  • Thermoplastics
  • Duroplastics
  • Elastomers
  • Compounds (material mixes)

Design, engineering, implementation of the extrusion tool according to customer-specific quality specifications. Extruder versions for multi-layer extrusion according to customer-specific requirements. Extruder version for direct extrusion and batch and compound manufacturing.

Performance characteristics

The range of AKMA Technology GmbH extruders includes single-screw extruders with a screw diameter from 15mm to 125mm with variations of length, and ratio of diameters from 15D to 33D. The standard solution of the extruders are fitted with an up-to-date PLC control where the process parameters of the extrusion process are shown on a touch screen and adjustable for an optimum extrusion process.

The extruder drive is adjustable and executed with a robust spur gear. Compact design allows a straight alignment within the entire extrusion line. The extruder screws are executed according to the customer-specific requirements, and depending on the plastic materials to be processed they are nitrated, hardened or made of high-alloyed temperature-resistant screw materials.
