MAGUIRE PRODUCTS, INC., founded in 1977, is a global technology leader in material management systems for plastics molding, extrusion, and compounding. Headquartered in Aston, Pennsylvania, U.S.A., Maguire has five production facilities in Aston and in Smithfield, Rhode Island. The company manufactures:

Gravimetric blenders
Granulators
Liquid color pumps
Volumetric auger feeders

For each of these equipment systems, Maguire has developed its own basic operating concepts, mechanical designs, electronic controls, and software.

One result is that the company is now the world's largest supplier of both gravimetric blenders and liquid color pumps.
