Four-Strand GFRP Bar Pultrusion Line

Equipment Introduction
Four-strand GFRP (Glass Fiber Reinforced Polymer) bar pultrusion line — high-efficiency production of four-strand glass fiber reinforced polymer bars. Simultaneous impregnation and forming of four fiber strands in one pass for improved efficiency and uniformity. Precision control delivers high tensile strength, excellent bonding, and tight dimensional accuracy. Designed for large-scale infrastructure projects demanding high output and consistency.

Main Components and Functions
Fiber Creel: Holds multiple rolls of fiberglass yarn, providing the fiber source for parallel production of four-strand bars.
Impregnation System: Ensures thorough resin saturation of the fiber bundles. Equipped with constant temperature heating (e.g., water bath heating) to maintain stable resin fluidity, achieving uniform impregnation.
Pre-forming Device: Preliminarily shapes the impregnated fiber bundles and squeezes out excess resin, preparing them for entry into the mold.
Heated Curing Die: The core component. Cures the resin through heating. Four-strand production lines use multi-cavity dies to form multiple bars in one pass. In addition to conventional electric heating, new technologies such as microwave heating are available for more uniform internal and external heating.
Pulling Device: Provides continuous and stable pulling force to draw the fibers through the entire production line. Available in hydraulic and caterpillar types, delivering sufficient clamping force without damaging the product surface.
Cutting Device: Automatically cuts the cured continuous profiles to preset lengths. Typically adopts a flying cut-off system that performs cutting while the product is in motion.
