Our Fiberglass Roving Production Proces
Uncovering the magic process that turns silica into high-quality fiberglass roving
Welcome to our Fiberglass Roving Production Process module! Here, you will discover how we transform ordinary silica into superior fiberglass roving. Let's delve into the key steps of our production process:

Raw material preparation

The main materials such as silica, limestone, and quartz sand are prepared to create glass melt. Our raw material is mineral and has a higher tensile strength than roving produced from glass spheres

Fiber drawing

The raw materials are melted in a glass furnace and then pulled using a special mechanism to form long, thin glass fibers. We adopt the most advanced furnace pull method technology.

Fiber coating

The drawn glass fibers are coated with a protective agent using a coating device to enhance their strength and durability. Coated with proprietary sizing to create corresponding enhanced rovings

Fiber forming

The coated glass fibers are wound together using a twisting mechanism to form bundles of yarn.

Packaging with pallet

Put the plastic-packed yarn into a tray for storage, 48/64 rolls per pallet, 48 rolls with 3 layers, and 64 rolls with 4 layers.

Plastic packaging

Roving that has passed the quality inspection is covered with plastic bags by full-time personnel, and plastic-sealed by special packaging equipment

Quality inspection

Before the glass fiber roving is packaged, there will be special personnel to check whether the weighing meets the production standard


The twisted yarn is dried and cured in a drying chamber or oven to remove moisture and obtain the desired physical properties.
