Brabender SpeciMold – In-line production of polymer specimen

Intended use

The Brabender SpeciMold offers a unique and comfortable quick method for your extrusion process. The machine continuously produces specimen from the extruded polymers and fillers – fully automatically, without any bypass or additional process steps, directly from the ongoing compounding process.


  • For a large variety of polymers
  • In-line production saves time
  • Preserved material properties
  • High operating comfort by automated processes
  • Editable injection molding parameters
  • Exchangeable injection molds

Time-saving and versatile new in-line production procedure

The SpeciMold produces polymer specimen in a single step in-line, not needing several process steps as conventional production procedures require. Thus, the specimen producer saves your time and is gentle to the used material, as it is only melted once in the process.

The specimen have exactly the same properties and characteristics as the extrusion polymer and are, therefore, perfectly suited for further mechanical property tests.

Stay flexible and use the SpeciMold the way you need it. For it is compatible with Brabender single and twin screw extruders as well as with third-party extruders, the injection molding parameters are easy editable and the injection molds can be changed quickly, giving you a great amount of possible specimen. 

Produce specimens according to this technical standards:

Tensile stress

Flexural properties


Impact test
DIN EN ISO 179/180

Temperature deflection under load

Compressive properties


Density determination

DIN EN ISO 1183-1

Hardness measurement
DIN EN ISO 2039-1

The SpeciMold is subdivided into a heated SpeciMold block with a piston and an injection die, and an injection mold which can be opened and closed through a toggle mechanism.

In a classical compounding line, the SpeciMold is positioned between the twin screw extruder and the extruder die head.

The polymer is homogenized, molten and transported as usual in the extruder. Then, the melt passes the SpeciMold block before it is shaped in the extruder die head, cooled down in the water bath, and cut in the pelletizer.

The SpeciMold suits a large variety of applications:

Material testing

  • in research and development laboratories

Quality assurance

  • in recipe development
  • in additive production
  • in compounding lines
  • Multipurpose specimen in compliance with DIN EN ISO 3167
  • Small plates in compliance with ISO 294-3 (2002)
  • Flow spiral

Further injection molds are available upon request.

The user-optimized control surface and process mapping of the SpeciMold software make parameter setting and handling of the machine very easy. Clear input masks facilitate the entry of process parameters like injection pressure, injection speed, and injection volume in order to optimize your specimen.


  • Selection between automatic and manual operation
  • Saving of the internal pressure curve of the injection mold
  • Input mask and live data display for each process step
  • Saving of material-specific process parameters
