What equipment is used in the production of fiberglass yarn?

Core Melting and Fiber-Drawing Equipment
Fiber-Drawing Furnace (Pool Furnace): Used to melt batch materials at high temperatures into a homogeneous glass melt; it serves as the core heat source for the entire production line.
Platinum-Rhodium Alloy Bushing: Features hundreds of tiny orifices that divide and draw the molten glass into ultra-fine filaments; it is the critical component determining fiber diameter precision.

Spinning and Forming Equipment
Direct Roving Machine: Designed for the specific properties of fiberglass, this machine uses double-apron drafting and dual-row twisting mechanisms to convert fiber strands into uniform roving. It achieves delivery speeds of 60–180 meters per minute, meeting mass production requirements.
High-Performance Industrial Yarn Energy-Saving Twister: Utilizes a direct-twist process that combines yarn plying, primary twisting, and re-twisting into a single operation. Equipped with proprietary twist-uniforming devices and anti-static systems, it processes ultra-fine fiberglass with filament diameters of only 1–3 microns, meeting the high-strength and low-fuzz requirements of the high-end electronics and aerospace sectors.
