had grown to occupy five small buildings, to a single, 90,000-square-foot factory building in Corona, Calif. AMA officials later closed the Tucson plant, and Corona became the official headquarters in 2002.

After a period of rapid expansion, in 2011 AMA moved to a 150,000-square foot plant in Riverside, investing about $10 million for the building, infrastructure improvements, plus 6.6 acres of land.

Recent injection molding press investments include a 240-ton Arburg two-shot machine and three more Toyos, of 50, 90 and 110 tons, plus a 200-ton all-electric press in a clean room.

The molder has used an IQMS system since 2005. Also, AMA practices decoupled molding.

AMA scored well in quality, customer relations, employee relations, and industry and public service.

AMA has shown steady improvement in quality, after a bump up in defectiveparts per million during the 2011 relocation from Corona to Riverside, AMA dropped problems per million parts to 1,248 in 2013.

AMA runs an advanced quality department, with several coordinate measuring machines and other testing devices.
