Carbon Graphite Product Manufacturing

We are one of the very few carbon companies across the world to develop and mix our own carbon grades. This allows us to customize any of our existing products or develop new products to meet the needs of your specific industry and application.We don’t simply machine a product to a different specification; we are able to alter the base materials and physical properties of our products to make them ideal for your needs.


We manufacture high-quality brushes to meet a wide range of OEM and aftermarket applications for a variety of industries, including Aerospace, Automotive, Construction, Mining, Power Generation, Printing & Paper, Renewable Energy and Transportation. Our brushes are made from the entire range of our customized grades in order to meet the specific demands and applications of our customers.
