Extruders Screws Control Systems Pelletizers Cooling Baths Accessory

maGme manufactures extruders to customer specifications for processing all commodity and engineering plastics (e.g. PE, PA, PP, PET, PMMA, PVC) as well as specialty materials, such as PEEK. Our high level of vertical integration allows us to customize each extruder to your specific process.

Our extruders are used from research and prototyping to production and product quality assessment.

We offer single-screw extruders for the production of pipes, profiles, cables, hoses and filaments as well as for pipe and profile sheathing.

Screw diameters in small increments of 14 to 18, 20, 25 and up to 45 mm and L/D ratios of 20, 25, 30 and 33 open a wide range of solutions.

Our extruders stand out for their rugged design, high flexibility and ease of use. Thanks to our high level of vertical manufacturing integration they can be supplied in a wide range of different versions.

Our core competencies are focused on the production of extruders, coextruders and pelletizers. We offer solutions tailored to customer specifications in all fields of extrusion technology.

Application Areas:

  • for the processing of PE, PA, PP, POM, PVC, PET, PBT, PMMA, PS, ABS, SAN, PC and PEEK ,PLAC, PTFE, as well as bioplastics and ceramics or other polymers
  • for the processing of corrosive and abrasive melts, thermoplastics, rubbers, silicones and fluoroplastics
  • for use as coextruders in film, pipe, blow molding and hotmelt processes
  • for the production of profiles, hoses and masterbatches as well as for cable sheathing


Processing Unit with Stand-Alone Control Cabinet
  • single-screw processing units with or without drive components, in configurations that can be matched to meet specific space requirements, with appropriate band heaters and ventilation acc. to customer specifications
  • design and production of individual processing units for special applications
Processing Unit for Fluoroplastics
  • barrels made from powder metallurgical materials or with coated surfaces, screws made from Inconel or Hastelloy or with special coating for the processing of corrosive plastics
Laboratory Extruder with Degassing
  • extruders with integrated degassing unit for enhanced product quality and reliability
Pressure Filter Testers
  • for comparing the quality of masterbatches in line with the standardized pressure filter test
  • for masterbatch testing acc. to European standard EN 13900-5
Recycling Extruders
  • equipped with special screws and barrels, for all thermoplastics, rubber blends, silicones and fluoroplastics
  • suitable for the processing of regrind, pellets or pelletized recycle
Smooth-Bore and Grooved Barrel Extruders
  • grooved feed for high throughput and pressure stability
  • All models can be equipped with motors conforming to energy efficiency classes IE2 through IE4. This leads to energy savings of up to 10%.
  • Together with a synchronous motor you will receive a processing unit of slim and short design that promises high flexibility.
  • A high-torque drive concept permits oil-free operation and offers the additional benefit of low maintenance.
  • Complementing our extruders equipped with bevel or spur gears, we use CMG compact transmission motors. This type of transmission provides for a compact processing unit with quadruple meshing. The use of a CMG gearbox with inboard motors adds to reducing the length of the processing unit.
  • The gearbox can be designed in Z, L or U configuration to match your space requirements.
