Lightweight construction

Save costs, increase efficiency and conserve resources with lightweight construction: Use innovative injection moulding processes such as fibre direct compounding (FDC) and physical foaming with MuCell®.

Benefits at a glance


Innovative products – cost-efficient, economical with materials and with a low carbon footprint? Pioneering lightweight construction processes have great potential.


Reducing part weight while maintaining or improving mechanical properties is your ambitious goal. And fibre-reinforced or foamed parts are two possible solutions.


How to make significant cost savings? Through optimised part design, reduced weight and the combination of different lightweight construction processes and materials.

In partnership

ARBURG is your partner. And active in networks that develop and optimise processes and materials. In addition to the technology, we also offer comprehensive technical advice.

Benefits of the FDC process

Reduced costs

Reduced costs

Combining carbon or glass fibre rovings and plastics such as PP, PA, PET and PC/ABSs is up to 40% cheaper than special glass fibre-reinforced PBT, for example.

Control system

Control system

The FDC process is fully integrated in the control system and dedicated symbols enable the process to be programmed easily and flexibly.

Gentle plasticising

Gentle plasticising

A special screw geometry enables gentle preparation of the melt and a high proportion of long fibres in the part. With an additional thermoplastic cylinder module, the ALLROUNDER can also be used for conventional injection moulding.

Direct compounding

Direct compounding

Continuous fibre strands are cut to the desired size via the lateral feeder and fed directly into the liquid melt. Mechanical part properties can be selectively influenced.


Fibre direct compounding

With the FDC process, you are free to choose the fibre length and proportion, meaning that you can selectively influence the part properties. The benefits for you? You can substitute more expensive materials and produce lightweight yet resilient parts.

Sample components


Cable drive housings made from PP with 30% long glass fibres (incinerated on the left) produced in the FDC process have a resilience similar to that of parts made from PBT and are also 30% lighter.

Garden shovel

If gas or water is introduced into the mould cavity using fluid injection technology (FIT), cavities can be created in the part. This significantly reduces materials and cycle time.
