Spray Yarn

Spray Yarn is a twist-free roving specifically designed for the injection molding process. It is suitable for a process where glass fiber is cut with a spray gun and sprayed onto a mold surface simultaneously with resin for molding. This process is suitable for the production of large, complexly curved products such as boats, bathtubs, and car bodies, which have high molding costs.

Material properties


—





Short cutting performance

—

High-speed cutting in the spray gun prevents unbroken fibers and tangles, and consistent cut lengths improve spraying efficiency, ensuring stable fiber ejection lengths and facilitating uniform molding



Molding performance

—

Good interlayer bonding strength, moderate resin-fiber ratio, can withstand light molding or rolling, sufficient exhaust, improve product structure density and surface smoothness



Bubble release

—

The fibers are evenly distributed, which is conducive to air discharge and easy for resin to penetrate, thus reducing air inclusion and lowering the void ratio in the product, thus avoiding defects such as white spots and delamination








Wetting speed

—

The yarn sizing agent has strong compatibility with the resin and can be quickly and completely wetted by the resin after spraying, shortening the operation time, improving production efficiency, and enhancing the fiber-resin bonding strength



Dispersion performance

—

The cut fiber bundles do not clump during the ejection process and can be evenly spread on the mold surface to ensure consistent product structure and uniform distribution of reinforcement materials, which helps to control local aggravation or weak areas
