    Automotive Hot Stamping

    Hot stamping, or press hardening, is an established process used in automotive manufacturing  to produce high-strength structural parts from thin sheet metal. The objective is to thermally-induce chemical changes in the metal at extremely high temperatures while forming it into the desired profile. This enables the fabrication of complex shapes with exceptional strength-to-weight ratios while all-but eliminating undesired phenomena like spring back. 

    Our rollers for hot stamping roller hearth kilns greatly improve efficiencies by reducing premature roller failure and maintenance related downtime. They are manufactured using a customized silicon carbide (SiC) material which offers unique advantages for every challenge. 

    Benefits:

    • Lower process rejections & maintenance costs
    • Long product life
    • Maintain - Enables rework and re-use
    • Customized solutions

    Beams

     

    Beams

    Beams are used to provide structural support for numerous high temperature kiln and furnace applications. They are available in at least three different materials, namely Silit® SK siliconized silicon carbide; N-Durance® nitride bonded silicon carbide, and Hexoloy® SE sintered silicon carbide. We offer a large selection of cross-sections, wall thickness and lengths (cross section as small as 12.5 mm and length up to 3 500 mm.). Beams are formed using slip-casting or extrusion processes. As-fired beams can be used "as-is" or finished to customer’s tolerances.

    two times larger than other advanced silicon carbide plates currently offered on the market.

    Benefits:

    • Increased setting space
    • Further reduction of structural supports and kiln furniture
    • Eliminate joints/seams underneath product
    • Flatness retention over large setting area
