Slack & Parr showcases high-precision metering capability at JEC World 2023

Slack & Parr is a world’s leading supplier of metering pumps for the production of PAN precursor used to manufacture carbon fibre. The company will be exhibiting on the Composites UK stand where it will highlight how its technologies are also being used to accurately manage the flow of resins and polymers in a number of composites manufacturing processes including coating, prepreg, filament winding and spraying, as well as in extruder-based processes most commonly used in the manufacture of thermoplastic composites.

Specific applications include the metering of two-part epoxy resins where Slack & Parr’s gear pumps are used to control precise amounts of the resin’s constituent parts to achieve a matrix with the exact characteristics required, while adapting to variations in pressure, speed and resin viscosity to achieve consistent flow throughout the process.

Slack & Parr’s metering pumps are built around hardened steel involute gears which are machined to precise tolerances of one or two microns. This results in extremely small, controlled clearances – measuring significantlyless than a human hair – between the gear and mating components, ensuring almost no internal slip even at high pressures. This level of precision means the pump is able to control or meter the flow with extreme accuracy and repeatability.

“The ability to accurately control the flow of resins and polymers is fundamental to the success of composite manufacturing,” says Slack & Parr’s Industrial Director Neil Anderton.

“Our pump solutions are relevant to every area of the composites industry where the need to precisely determine the fibre-to-resin ratio is key to the manufacture of high-quality composite materials and parts.

“We’re excited to share our metering technologies with more of the composites industry at this year’s JEC World and look forward to discussing how our solutions can deliver accuracy, consistency and repeatability into the manufacturing process.”
