MMI Baseplate Division was the first in the industry to design, develop and mass produce the world's first Aluminum Baseplate machined from a solid block of aluminum for helium filled hard disk drive which demands highest precision machining and tightest quality control.

We have some of the industry’s topnotch production and metrology equipment to ensure the desired quality is being achieved. Our Electroless Nickel Plating facility runs with high degree of automation and parameters control to meet the desired consistency.

Since 1989, MMI Baseplate Division has been supplying high volume, highest quality die-cast HDD Aluminum baseplate with fully vertically integrated in-house capabilities including Mold Design & Fabrication, Casting, Secondary Process, Electrocoating, Precision Machining, Aqueous DI Washing & Various Final Inspections.

A multiple Best Mechanical Supplier Awards winner with our latest product development including Vacuum Casting to meet HDD’s future needs.

Sole supplier for several years to its major customer in developing and producing multiple models of precision machined SSD Casing to secure and capture this growing storage segment.

A Voice Coil Motor Assembly (VCMA) is a set of strong rare earth magnets bonded to steel plates. The magnetic field provided by the VCMA interacts with the actuator arm's wire coil to generate the high frequency movements for the magnetic heads to read and write data accurately over the rotating disk.

MMI's advantage in VCMA is in electromagnetic systems design and testing capabilities, many of which unique and patented.  Some VCMA designs can be rather complex with pins, spacers, rubber stoppers and actuator letches built into the VCMA.  For these more integrated designs, tooling must be highly customized and advanced to achieve a high degree of automation.  The internal manufacture of the plates holding the magnets is an added cost advantage.  Finally, all MMI VCMAs are assembled in the industry's most advanced automated production lines that are designed by our own factory automation equipment unit to deliver the highest quality products.

The Top Cover together with the Base Plate form the enclosure system for the Hard Disk Drive. Its primary function is to provide sealing, protection and robustness to the Hard Disk Drive.

Apart from the above primary function, in today’s Permanently sealed  Helium Filled Hard Disk Drive, the Top Cover’s function goes beyond the need of providing an air tight seal to a full hermetic seal. The manufacture of such covers require special know-how to ensure our covers work seamlessly with our customers’ sealing processes.

Top Covers are typically designed for acoustics and vibration and manufactured with pre-laminated materials and/or dampers which can be implemented with different materials and damping adhesives.

MMI's factory automation and systems integration unit offers turnkey Design-and-build or Build-to-Print solutions for fully automated assembly lines to stand-alone station process equipment.
