From the initial design phase to the final product, we work closely with our clients to ensure that their specific needs are met and that they receive the best possible carbon solutions for their unique, high temperature applications.

  • Carbonization

    Carbonization is a pyrolytic process that removes atoms other than carbon from carbon bearing substances through controlled heating in the absence of oxygen. As the raw material undergoes carbonization, it transforms into charcoal, activated carbon, and other valuable products. This method enhances the durability and purity of carbon-based materials It is used in sectors such as energy production, filtration, metallurgy, and aerospace. With its ability to harness the potential of carbon, carbonization presents a versatile material solution.

  • Graphitization

    Graphitization is a sophisticated thermal treatment method performed in high temperature furnaces that improves the structure and crystallinity of some  carbon materials. This process involves subjecting candidate carbon materials to extreme heat, which leads to the rearrangement of carbon atoms into a layered, hexagonal lattice structure. Graphitization enhances the properties of carbon with improving strength, thermal conductivity, electrical conductivity, and reducing impurities. This remarkable transformation enables the utilization of carbon in a wide range of industries, including aerospace, automotive, electronics, and energy storage. Our advanced high temperature furnaces provide precise control over the graphitization process, ensuring superior quality and consistency of the resulting graphite products.

  • CVI Densification

    We offer an advanced solution for achieving superior material density through Chemical Vapor Infiltration (CVI). CVI is a specialized process that controls deposition of carbon precursors onto a porous substrate, resulting in the gradual infiltration and densification of the material. By introducing gaseous carbon-containing compounds into a high temperature environment, the carbon atoms react and deposit onto a carbon substrate surface, filling the pores and creating a solid, dense carbon/carbon composite structure. This innovative method produces high-quality carbon materials with enhanced mechanical strength, improved thermal conductivity, and excellent dimensional stability. Our state-of-the-art high temperature furnaces provide the ideal environment for precisely controlling the CVI process, ensuring consistent and reliable densification of carbon materials applied to  industrial applications, aircraft, automotive, defense, and space.

  • Heat Treatment

    Heat treatment is a vital process that utilizes high temperature furnaces to alter the properties of carbon-based materials, enhancing their mechanical, thermal, and electrical characteristics. Through controlled heating and cooling cycles, heat treatment enables the modification of microstructures, resulting in improved properties of carbon materials, used in aerospace, automotive, electronics, and tooling. Our advanced high temperature furnaces provide precise temperature control and uniform heating, ensuring consistent and reliable heat treatment processes.

  • Preforms: Needling, Die Cutting

    Needling and die cutting are crucial steps in the production of carbon-based materials, specifically nonwoven carbon felt preforms. Needling involves mechanically interlocking carbon fibers using barbed needles.  BAM has the ability to make flat nonwoven parts and also some capability to make shaped nonwoven preforms.  This process creates a preform with defined fiber volume fraction and fiber architecture.  Die cutting employs specially designed cutting tools to make the preform into dimensions, ensuring subsequent processes are efficient. Once the preform parts have been prepared, they are ready to undergo carbonization in our high temperature furnaces. 


  • Finishing: Machining, Grinding

    Machining and grinding serve as essential finishing techniques to increase density for carbon materials used in brakes. Machining involves precision cutting and shaping of the brake pads to achieve desired dimensions and smooth surfaces, ensuring proper fit, friction, and functionality. Grinding utilizes abrasive tools to remove excess material, refine the surface, and improve the overall density of the brake pads. These finishing services play a crucial role in ensuring uniformity, consistency, and superior performance of the final brake pad products.
