Increase FRP uptime and keep production moving.

With the new Graco RS Chop Gun, workers can change the unique "no-cut" blade cartridges in a matter of seconds – compared to 15 minutes with traditional cutter designs.

In addition, blades and anvils can be changed right on the production line, resulting in more uptime for your fiberglass reinforced plastics operation. Its lightweight design is up to 44% lighter than the competition for better spraying control.

The Graco RS Chop Gun delivers a superior spray pattern, with reduced VOC emissions as well. Graco has designed a gun specifically to spray fiberglass reinforced plastics (FRP) that is reliable, lightweight and is easy to maintain.

The RS chop gun or “chopper gun” uses a mounted fiberglass cutter, that makes sure you add cut pieces of fiberglass into the catalyzed resin stream for added strength and stability. Quick blade changes

The fiberglass chopper gun standardly uses a magnetic cutter drum, which uses a magnet in the cutter head which holds the blades in place.

This makes blade changes quick and easy But Graco now also offers the option to use blade cartridges in stead of he magnetic drum. Cartridges add convenience and speed to the production line.

Blades can be switched in under a minute, right on the production line. No more stopping production to switch guns. No more taking the gun to the workbench. Instead, blades can be quickly switched on the production line.

Blade cartridges are available in 4,6 and 8 blades Lightweight design Its lightweight design allows for a better spraying control. The Graco RS Chop Gun delivers a superior spray pattern, with reduced VOC- emissions (Volatile Organic Compounds) as well.
Features
  • Easy-to-change blade cartridges keep production moving.
  • High output cutter provides the output you need with fewer strands of roving.
  • Less roving means less tangling, more uptime.
  • External adjustable anvil tension - no disassembly, no tools required.
  • Speed control lets you adjust glass output on the fly.
  • Air Assist Containment (AAC) standard.
  • Available in internal and external mix models. Tool-less blade design:
  • No tools required – easy to change blades in seconds.
  • Ability to change blades on the production line resulting in more uptime.
  • Operators never have to touch a blade.
  • Virtually eliminates nicks and cuts.
