Stories like his are why 78% of our clients return year after year.

In this article, we’ll explore the critical role of fiberglass spray up roving in modern manufacturing, address common industry pain points, and explain why partnering with a spray up roving factory like Niumaterial guarantees unmatched value.

What Is Spray Up Roving?

Spray up roving is a specialized form of fiberglass reinforcement designed for high-speed, high-volume production processes. Unlike traditional woven fabrics, it consists of continuous glass filaments bundled into rovings, which are then chopped into predetermined lengths and sprayed simultaneously with resin onto molds. This method ensures rapid, uniform coverage—ideal for creating complex shapes in automotive parts, marine components, and wind turbine blades.

At Niumaterial, our fiberglass spray up roving is engineered for exceptional compatibility with polyester, vinyl ester, and epoxy resins. Our proprietary manufacturing process ensures minimal fuzz, superior wet-out, and consistent strand integrity—factors that directly translate to faster production cycles and reduced waste for clients. For example, a European automotive client reported a 15% reduction in material waste after switching to our roving, thanks to its flawless dispersion during spraying.

What Is the Process of Spray Up Fiberglass?

The process of creating spray up fiberglass is both intricate and fascinating. It involves several key steps that ensure the final product meets the highest standards of quality and reliability.

Raw Material Preparation: The journey begins with the selection of high-quality raw materials. At Niumaterial, we source our materials from trusted suppliers, ensuring that every batch meets our stringent quality standards. The raw materials are then processed into continuous strands of fiberglass, which are the foundation of our fiberglass spray up roving.
Mold Preparation: The next step involves preparing the mold or surface onto which the fiberglass spray up roving will be applied. This is a crucial stage, as the quality of the mold directly impacts the final product. Our experienced technicians ensure that the mold is clean, smooth, and properly coated with a release agent to prevent the fiberglass from sticking.
Spraying Process: The heart of the process is the spraying stage. Our skilled operators use specialized equipment to spray the fiberglass spray up roving onto the mold. The fibers are sprayed in a controlled manner, ensuring even distribution and optimal fiber orientation. This step requires precision and expertise, as the orientation of the fibers affects the strength and flexibility of the final product.
Curing and Finishing: Once the fiberglass spray up roving has been applied, the mold is allowed to cure. This process involves a combination of time and temperature, ensuring that the fiberglass hardens and bonds properly. After curing, the final product is carefully removed from the mold and inspected for quality. Any necessary finishing touches are applied to ensure the product meets our high standards.

Throughout this process, Niumaterial‘s commitment to quality is evident. Our state-of-the-art fiberglass spray up roving factory is equipped with advanced monitoring systems that ensure every step of the process is executed with precision. Our experienced team of technicians and engineers oversee the production, ensuring that every batch of fiberglass spray up roving meets our stringent quality standards.

Can Fiberglass Be Sprayed?

Absolutely! Spray-up is one of the most efficient methods for producing fiberglass parts. However, success hinges on using the right roving. For instance, our fiberglass spray up roving supplier team recently collaborated with a North American marine manufacturer struggling with delamination in boat hulls. By switching to Niumaterial’s roving—optimized for high resin uptake and adhesion—they achieved a 20% increase in part durability while cutting labor costs by 12%.
