ORLANDO, FLA. (April 4, 6:30 p.m. ET) — Maguire Products Inc. has enhanced its Purging Recovery System that transforms purgings into regrind to expand its capabilities and increase its efficiency.

The new design will allow the company’s PRS system to work with shear-sensitive polymers such as polystyrene—which can melt as frictional heat builds up in standard equipment , and with flexible vinyl which stretches when worked by cutting blades and can jam conventional granulators.

The Aston, Pa., company said the design improvements permit reclaim of the 85 Shore A vinyl that is commonly used in wire and cable.

“PRs systems now in use by injection molders who make multiple changes consistently recover purgings at a rate of 1,000 pounds per eight-hour shift,” said Maguire’s vice president of marketing and sales B. Patrick Smith. “If the polymer is worth one dollar per pound, the PRS pays for itself in 30 shifts.”

Maguire said its enhancements include the configuration of the eight rotor knives making up the plane, new clearances around the plane, and the angle of attack of the knives between the purging and the plane.

The company also cited the low-energy use and price of its products.

According to Maguire, its PRS system uses three small motors with a combined horsepower of 11, compared to a standard heavy-duty granulator that typically has a motor size of 100 horsepower or more.

In addition, the company said its PRS system is priced at around $30,000 compared to the typical price range of $100,000 to $200,000 for standard heavy-duty granulators.
