Applications

Waterproofing Membrane

These fabrics form a key component in technical textiles, offering versatility through top/down polymer coatings that provide both waterproofing and weldability. Typical processing operations include the application of PVC or TPO layers, surface treatment for enhanced adhesion, and multilayer coating techniques to achieve specific performance properties for demanding industrial applications and diverse end-use requirements.

Engineering Plastics

Whether processing PA, PC/ABS or high-performance materials such as PEEK and PPS, KraussMaffei Extrusion’s twin-screw extruders provide stable and efficient compounding performance. Our solutions enable high output rates despite low specific energy input levels. Reliable processing is ensured for high-temperature polymers, optical-grade materials and sensitive functional fillers for demanding application requirements.

Our Process

Upstream Processing

Before processing, raw materials are carefully evaluated in our laboratory, including moisture content, bulk density, and other relevant material properties.
Material handling is individually adapted to match each customer’s specific production setup, ensuring smooth integration into existing process chains and stable downstream processing.
High-precision gravimetric dosing systems ensure consistent and reliable formulation accuracy, supporting stable product quality and repeatable processing results across production batches.

Extrusion

The materials are fed into the intake zone in a controlled manner. After melting, fillers and sensitive additives are incorporated through side feeding. Vacuum degassing removes moisture and volatiles, ensuring consistent product quality. Final result is a homogenous melt.

Forming and Downstream Processing

KraussMaffei Extrusion provides process solutions for pelletizing using underwater, strand, or hot-air pelletizing techniques.
Following pellet formation, drying and conditioning are achieved through vibration conveyors to ensure uniform moisture reduction and stable handling.

Logistics

KraussMaffei Extrusion manages the entire logistics process – from worldwide shipping to onward transportation for downstream processing steps. Whether by land, air or sea, or via on-site collection, we reliably coordinate the transportation of machinery, plastics and rental equipment according to your requirements and ensure their integration into customized process engineering systems. With fully digitalized, SAP EWM-supported processes and integrated hazardous materials management, we ensure safe, efficient and internationally coordinated logistics.
