Processing Technology for Long-Fiber Thermoplastics
|
|
LFT-G® injection molding process is built around a purpose‑designed screw and barrel configuration tailored for long‑fiber reinforced thermoplastics. The screw geometry uses a gentle conveying profile that minimizes fiber attrition during melting, preserving the continuous‑fiber network achieved in our pultruded pellets right through to the finished part. This standardized platform ensures consistent, repeatable performance across production sites with very low variability between batches.
Low‑shear melting reduces fiber breakage and promotes uniform fiber dispersion, even in parts with intricate geometries. Precise melt temperature regulation and optimized backpressure help maintain the three‑dimensional fiber architecture critical for high impact strength. Modular screw designs offer flexibility to handle different material viscosities and part requirements – from thin‑walled housings to robust metal‑replacement components. Key benefits include shorter cycle times, minimized distortion, and reduced need for post‑molding finishing, leading to lower total system cost without sacrificing mechanical properties. |
Operating Instructions for Injection Molding

| Parameter | Recommended Range | Key Notes for LFT-G® HPP LCF40 |
| Drying Temperature ① | 90 – 110 °C | Use a desiccant/dry air dryer to avoid hydrolysis |
| Drying Time ① | 3 – 4 hours | Ensure uniform moisture removal before processing |
| Melt Temperature (Nozzle) ③ | 210 – 240 °C | Avoid overheating to preserve fiber integrity |
| Mold Temperature ② | 40 – 60 °C | Balances flowability and part dimensional stability |
| Injection Speed | Slow to Moderate | Minimize fiber breakage and internal shear |
Critical Tips:
Screw: Low-compression screw to reduce fiber breakage
Gating: Generous gating for smooth material flow
