DIEFFENBACHER LFT-D Technology Opens Up New Opportunities

January 04 (2021

By increasing the flexibility and throughput of its LFT-D plants, DIEFFENBACHER is helping thermoplastic component manufacturers capitalize on increased demand for their products.

E-Mobility and the Circular Economy are two global trends boosting demand for thermoplastic processes and components made of thermoplastics. Fiber-reinforced thermoplastics offer the ideal properties for applications such as battery cases for electric vehicles. In addition, unlike thermosets, thermoplastic components can be produced from recycled materials such as production waste or product returns.

To produce these and similar components economically on a large scale, DIEFFENBACHER has increased the flexibility and throughput of its LFT-D plants. This added flexibility allows the use of recycled polymers while also increasing plant performance.

DIEFFENBACHER LFT-D plants typically use a two-machine technology with two extruders whose parameters such as speed, temperature, etc. can be set independently of each other. To make this conventional LFT-D technology more efficient and flexible, new and expanded DIEFFENBACHER lines have larger extruder pairs specially designed for the use of different thermoplastic materials.

Another benefit of the new LFT-D technology: in combination with other processes such as the DIEFFENBACHER Tailored-Blank technology, manufacturers can produce components with sophisticated mechanical properties. The patented plant technology enables the material-efficient and load-dependent use of UD tapes. Back-injection molding in closed compression mold or hybrid solutions provide further possible combinations.
