Beyou LFT-G Long Glass Fiber Impregnation Extrusion Production Line For Sale

LFT-G (Long Fiber Thermoplastic Granules) materials are increasingly adopted in industries such as automotive, rail transit, appliances, and construction due to their excellent mechanical strength, thermal resistance, and dimensional stability. Compared with short fiber composites, LFT-G offers superior tensile strength, impact resistance, and fatigue performance—ideal for structural applications demanding high load-bearing capacity.
This production line integrates continuous fiber drawing, resin impregnation, coating, cooling, and pelletizing into a streamlined process. Compatible with glass fiber, carbon fiber, and various thermoplastics such as PP, PA, and TPU, it utilizes modular die structures and precise thermal control to ensure effective fiber wetting and uniform polymer coating. The resulting pellets exhibit smooth surfaces, consistent fiber length, and excellent dispersion.
Equipped with synchronized automation systems, the line achieves stable high-speed operation with a single-strand throughput of up to 25 kg/h. Features like online fiber rethreading and non-stop splicing ensure minimal downtime and a product yield of up to 99%, significantly enhancing production efficiency.

Why Choose Us

Our production line uses a screw press to melt-impregnate continuous glass fibers and granulate them online, maximizing fiber length. Long fibers, after injection molding, give the finished products excellent mechanical strength, impact resistance, rigidity, and creep resistance, far exceeding the performance of short glass fiber materials.

Through modular impregnation and precise control, we ensure that the fiber content is adjustable within a wide range of 20%-70%, resulting in smooth, lint-free granules with consistently high quality.

The production line has online fiber threading and high-speed splicing capabilities, significantly reducing downtime. Combined with stable high-speed operation up to 60 meters per minute, this greatly improves production efficiency and product quality.

The traction mechanism automatically swings to extend its lifespan, and granulation achieves zero tailing and cracking. The cutter has an exceptionally long lifespan, with a maintenance cycle exceeding 600 tons, effectively reducing operating costs.

The entire line is automated, enabling synchronized front and rear speeds and one-button operation, greatly simplifying the production process and easily achieving stable, efficient, and high-quality production.
