Company Profile

In 2008 Poco Graphite was acquired by Entegris, Inc, a well-known materials and components supplier to the Semiconductor industry. The acquisition increased Entegris’ materials portfolio through the offerings of graphite, silicon carbide and highly conductive foam materials. These new offerings were combined with the Entegris’ specialty coatings business unit to form the Entegris Specialty Materials Business Unit. The combination of POCO’s carbon based and Entegris’ advanced coatings solutions has enabled an innovative approach to both the EDM and glass bottle manufacturing markets. These materials and coatings will also support leading edge applications in Semiconductor, Aerospace, Biomedical, and Alternative Energy.

POCO’s many grades of premium graphite set the standard for EDM graphite performance. Today’s product line includes more than 100 grades of graphites used in EDM, semiconductor and other industrial applications. POCO stands out for producing graphite that is consistent from block to block and run to run. POCO achieved ISO 9001:2008 and AS9100:2009 certifications, echoing a commitment to quality that has been POCO’s heritage since 1964.

The POCO EDM Technical Manual has been the industry’s leading resource of EDM technology and electrode material selection for the past four decades. During this time, several revisions have been made to expand the information provided in this manual. These revisions include adding EDM performance charts and transitioning from the printed version to a CD-Rom format. In 2013, POCO released the on-line format for instant web access. Key improvements in this web version included the ability to email performance charts, contact a technical advisor via email for assistance, and a reference section containing technical articles and other resource materials for immediate download. In 2014, we released the EDM Tech Manual app for iOS and Android systems. Now in 2015 we have the app available with metric conversions.

Please visit www.EDMTechMan.com to access the POCO EDM Technical Manual. Check often as continual updates will be made to further improve the quality of the information provided by Poco Graphite.
