JUNE 2015 58 CompositesWorld » SPRAY EQUIPMENT Quick-change chopper gun Graco (North Canton, OH, US) has launched its RS chop gun for the fexible and precise application of fber-reinforced plastic (FRP) in the marine and other markets. This 13:1 chop system proportioner is said to ofer precise on-ratio dispensing with easy transition from wet-out to chop. The system is designed such that no surge bottle is necessary and a low amount of solvent and resin is needed to prime the pump, so material costs are kept low. A dual trigger function enables operators to change from wet-out to chop without turning the chopper of. Additionally, the gun has what Graco says is a uniquely designed blade cartridge in which the are blades are molded directly into the cartridge. Operators can change blades without touching individual blades and without use of a special tool, thereby increasing operator safety and making it possible to change blades in less than a minute. www.graco.com/composites » DISPENSING EQUIPMENT Retrofittable pumping system for liquid/paste application UK Flowtechnik (Nottingham, UK) has launched the trademarked VISCO.pump, designed by Beinlich Pumpen GmbH (Gevelsberg, Germany), the renowned manufacturer of gear and radial piston pumps designed specifcally to enable the precise dosing of fuids and pastes proportionate to the rotational speed. Its pumping principle enables precise dispensing of beads and dots as required, as part of an automated process. VISCO.pump is said to accurately dispense liquids and pastes with up to 60% fller content. The dosing quantity can be set to be absolutely linear, with dosing accuracy/ repeatability of ±1% or less. The company claims the pump's linear volumetric efciency and high predictability on delivery makes the pump almost "plug-and-go" — it is reportedly much easier to use than other pump designs and the cost of installing and commissioning it is comparatively low, and it can be retroftted into existing systems, if required. www.ukfowtechnik.com EXPERT ACCESS Direct access to industry thought leaders and technical experts CompositesWorld.com Closed Mold Knowledge Center PRODUCT AND PROCESS TECHNOLOGY Complete closed molding process overview: • Light RTM • Reusable bag molding • Vacuum infusion Access to Closed Mold Alliance supplier network TECH SUPPORT & EDUCATION Training and consultation solutions for all aspects of closed mold conversion E D Knowled P C • A T Tr m er NOLOGY PRESENTED BY: Get the Information you need on Closed Molding Today! compositesworld.com/knowledgecenter/closed-molding/ NEW PRODUCTS
