MGM Record Manufacturing Division

A Bloomfield, New Jersey-based division of Metro-Goldwyn-Mayer that exclusively pressed vinyl format releases for MGM Records and its subsidiary labels from March of 1947 until 1971 (after 1971, MGM outsourced much of its East Coast pressings to Keel Mfg. Corp.).

It operated in conjunction with MGM Custom Pressing Division, which offered recording, mastering, stereo, shipment, and pressing services to other clients.
