DCIM Technology

Direct Compounding Injection Molding - Clever compounding integration

Product information

With Direct Compounding Injection Molding (DCIM), an additional extruder with a single screw is adapted to a standard injection molding machine and enables the direct compounding of thermoplastics in an inline process. This allows material costs to be significantly reduced, in-house formulation expertise to be built up and a significantly reduced CO2 footprint to be achieved.

„The material quality lies with DCIM at ZF, and we have protected the expertise in-house, fully documented and tested."

  • Significantly reduce material costs
  • Tailor-made material properties
  • Secure competitive advantage through recipe know-how
  • Drastically reduce your carbon footprint
  • Sustainable and material-friendly production
  • Replacing complex multi-stage processes
Single-screw extruder
  • Space-saving piggyback position on the injection unit
  • Special screw design designed for material compounding
  • Process length extended to 30L/D for optimum material homogeneity
  • Discontinuous operation tailored to the injection molding process.
  • Fully integrated into the injection molding machine

=> Excellent compounding quality combined with maximum flexibility in both material recipe design.

Gravimetric single-component dosing
  • Individual component weighing
  • Dosing device ideally matched to the type of raw material
  • Partially integrated into the machine control system
  • Proven technology from the compounding industry
  • Free choice of dosing devices, from economical “grav. batch blenders” to high-end “loss in weight” devices

=> Perfect dosing technology for all types of matrix materials, fillers, and reinforcing materials

Standard injection unit

Injection unit with 3-zone screw and melt transfer:

  • Short and flow-optimized melt transfer from extruder to injection unit
  • Genuine melt temperature measurement and pressure monitoring at the transfer point
  • Injection using a standard injection unit with 3-zone screw
  • Automatic coordination of the two processes, extrusion and injection molding, by the machine control system

=> Well-known and proven technology for component filling combined with the requirements of compounding

Material feed for production without pre-compounding.

Material feed for production without pre-compounding:

  • Standard material hopper on the flange of the injection cylinder
  • Easy selection and deselection of the compounding extruder on the control panel

=> Versatile application of the machine, even as a standard SGM without extruder
