San Francisco, CA (December 2, 2013)—entrotech Inc. announced that TDK Corporation as a global electric components company has agreed to purchase of two entities of entrotech, Inc., a California-based technology materials and product innovator.

The acquisition was accomplished via TDK’s subsidiary, Magnecomp Precision Technology (hereinafter MPT), a leading hard disk drive suspension supplier. The companies, entrotech and TDK also established a strategic partnership.

Under the agreement, effective October 11, TDK purchased two entrocomponent solutions companies, EntroComponent Solutions, LLC located in Chino, CA and EntroComponent Solutions Singapore Pte Ltd located in Singapore. Both companies specialize in the manufacture of polymer-centric components, essential to hard disk drives (HDD) for computer and cloud storage technology.
