Long and short fiber parts can be manufactured with excellent structural integrity and consistency.
High process stability in automated mass production with repeatable quality output.
Optimized weight-to-performance ratio for demanding structural applications.
Injection moulding of fiber-reinforced thermoplastics enables the production of high-strength, lightweight technical components with excellent stiffness, impact resistance, and process efficiency.
Thermoplastics are commonly reinforced with short or long glass fibers, typically ranging from 15–50% fiber content, while advanced structural applications may require fiber contents exceeding 60%.
Fiber-reinforced thermoplastic pellets are plasticized in a wear-protected plasticizing unit
Special screw geometries reduce fiber breakage and material degradation
Melt is injected into mould cavity with optimized flow control
Injection compression and tailored mould design improve fiber integrity
Component is cooled and ejected as a structural part
Long-fiber solutions are particularly suited for semi-structural and impact-resistant automotive components, providing exceptional durability under real-world conditions.
The use of long-fiber-reinforced thermoplastic pellets (12–25 mm fiber length) significantly enhances the mechanical performance of structural components.
Specialized processing solutions ensure that the reinforcing advantages of long fibers are retained during plasticizing and mould filling for optimal performance.
Fiber-reinforced injection moulding is widely used for semi-structural and load-bearing components:
