Man's desire to explore space and safely return led to the development of specialty materials that could withstand high temperatures during reentry. One of these materials in the race to conquer space was a specialty graphite developed by a Texas based aerospace company. Because an alternate material was selected for this application, this unique technology was sold to Pure Oil Company in 1964. This graphite division became known as POCO, an acronym for the new owner. POCO's specialty graphites finally made it to outer space in 1977. This material was used in the radioisotope thermoelectric generators onboard Voyager I and Voyager II. Today, Poco Graphite is owned by an investment group led by SG Capital Partners and Whitney & Co. SG Capital Partners has a long history of working with high growth industries and technology companies to build strategic partnerships. SG Capital Partners LLC is the American merchant banking affiliate of Société Générale Group, one of the ten largest banks in the world. Whitney & Co., founded in 1946, was the US’s first venture capital firm. Whitney & Co. has over $5 billion in invested capital and has a strong record of identifying and partnering with companies poised to take advantage of growth opportunities. POCO materials are used in many diverse applications and industries. POCO products are produced for the following major markets: Semiconductor and general industrial products, biomedical, glass industry products and electrical discharge machining (EDM). As a producer of highly technical materials, POCO offers exceptional customer support, including specific application information, design capability, machining and materials testing.

Hardness, wear resistance, deposition temperature and uniformity are the main elements to consider when choosing a coating for mold components.

An actual application and comparison of the cost effectiveness of two different electrode materials.
Using the graphite TCO model shows business owners how to save time and money in their EDM operation.
When all the factors of the EDM process are taken into consideration, savings on the electrode material cost can result in a much larger overall cost.
A discussion of the reasons why the use of more, economical electrode material is not always the most cost-efficient means of CNC EDM
The production of fine surface finishes in the cavity does not come with the technological improvements of the EDM sinker unless an electrode material of higher quality is used.
Each POCO grade of EDM graphite has been tailored for a specific range of applications with benchmarked performance characteristics.
POCO set the industry standard for electrode performance with EDM-3, the most widely used graphite for production of plastic injection cavities.
To improve the potential for success in quality mold production, moldmakers need to understand some specific characteristics of the electrode material as well as certain facets of the EDM process that affect surface finish and integrity.
Not only is Poco Graphite (Decatur, TX) known as a manufacturer of superior EDM graphite electrode materials, but also as a provider of EDM performance solutions.
Understanding the various layers of a cavity that are thermally altered by the EDM process will help you understand how EDM affects the integrity of the mold surface.
EDMing with exotic metals requires a little something extra, like copper graphite electrodes.
EDM-3 is the graphite grade of choice for many precision moldmaking applications.
EDM-3 from POCO Graphite, USA (Decatur, TX) is the graphite grade of choice for many precision moldmaking applications.
The solution to solving problems associated with EDMing high copper alloy work metal involves finding the right graphite electrodes.
POCO Graphite, Inc. (Decatur, TX) introduces EDM-4 graphite for EDM electrodes, which is now the premium material in the Ultrafine classification, offering improved wear and surface finishes during finishing operations.
Ultrafine-classified EDM-4 graphite is said to offer improved wear and surface finishes during finishing operations.
EDM-4 graphite, developed for mold shops that need high performance in critical applications, has been introduced by Poco Graphite (Decatur, TX). The graphite—with a smaller grain size and higher strength than the company’s EDM-3—has less wear and produces better surface finishes.
Graphite selection is the key to achieving optimum performance from the equipment on your shop floor.
Selection of the proper graphite grade requires an understanding of the physical properties and how they affect electrode fabrication and performance during the EDM process.
Using the graphite TCO model shows business owners how to save time and money in their EDM operation.
While many moldmakers believe that they can get away with lower-grade graphite if they have a quality EDM machine, in reality, the quality of graphite plays a much larger role in achieving the right EDM finish.
