Types of Fiberglass Guns
Chopper Guns
Chopper guns are primarily used for general fiberglass applications. They provide a quick and efficient way to apply fiberglass strands mixed with resin, making them ideal for large-scale projects. The RS Chopper Gun from Graco, for instance, is designed for efficiency with a high-output cutter and a magnetic drum for constant control. These features enhance productivity by reducing downtime.
Gear-Reduced Chopper Guns
For applications that require precise control over the volume of material being applied, gear-reduced chopper guns are the ideal choice. These guns, such as the CGA16, allow operators to adjust the chopping speed and control the output, making them suitable for intricate projects where accuracy is paramount.
Handheld Chopper Guns
Handheld chopper guns are versatile tools that cater to both large and small jobs. They are lightweight and easy to operate, making them perfect for field repairs or smaller-scale applications. The CDA-16 from Epoxy World is a popular choice in this category, offering a compact design and adjustable strand length.
Gelcoat Dump Guns
These guns are specifically designed for applying gelcoat, a protective and aesthetic layer used in fiberglass products. Gelcoat dump guns, like those from uscomposites.com, offer a user-friendly design that allows for quick cleanup and easy operation, which is essential for maintaining efficiency in a production environment.
Spray Guns with External Mix
External mix spray guns provide an advantage when it comes to catalyzed applications, ensuring a thorough mix of resin and hardener. These guns are particularly useful in situations where precise proportions are essential for product quality.
