Milacron Makes $30 Million Pension Prepayment

CINCINNATI, OHIO, September 18, 2006...Milacron Inc. (NYSE: MZ), a leading global supplier of plastics-processing technologies and industrial fluids, made a voluntary advance contribution to its U.S. defined benefit plan of approximately $30 million on September 15. Credit for this pre-funding will eliminate any contributions required in 2007, currently estimated at approximately $57 million.

Milacron is in the process of selling various other non-core, non-operating assets such as land, facilities and equipment made redundant through current and previous consolidations.
