The Manufacturing Process for Cemented Tungsten Carbides

The Basics of Tungsten Carbide Tooling, in Black & White

General Carbide is a leading manufacturer of tungsten carbide preforms and blanks used in wear, cutting and metalforming operations worldwide.

We achieved our market position through the drive and imagination of our founder, the late Premo J. Pappafava (1926-2002), a chemical engineer who established the company in 1968. Prior to becoming an entrepreneur, Premo enjoyed a 20-year career with U.S. Steel, Allied Chemical, and Firth Sterling. He worked for those companies following his graduation from Carnegie Tech (now Carnegie-Mellon University).

Premo’s legacy continues through his daughter, Mona Pappafava-Ray who, like her father, is a graduate of Carnegie-Mellon University, where she earned a degree in industrial management. That commitment to excellence also lives through the matchless dedication that General Carbide employees have to building long-term customer relationships.

One of Premo’s lasting contributions to the cemented carbide industry is a paper titled The Manufacturing Process for Cemented Tungsten Carbides. Premo’s vast technical knowledge, and ability to communicate his ideas clearly, make this document a “must-read” for anyone who wants an overview of formulations, manufacturing processes, and the tests that are conducted to verify product quality.

We hope you find this paper informative, and that you get in touch with one of our sales engineers for additional information.
