CCEWOOL® PCW Shapes for Dental Porcelain Furnaces

CCEWOOL® polycrystalline fiber shapes for dental porcelain furnaces are manufactured from high-purity in-house produced polycrystalline fibers using a vacuum forming process, followed by precision CNC machining according to technical drawings. These components can be custom-designed based on the heating curve and structural requirements of porcelain furnaces.

Specifically developed for dental porcelain furnaces and zirconia sintering equipment, the product provides stable thermal insulation performance and reliable structural support under high-temperature conditions.

When used in combination with silicon molybdenum (MoSi₂) heating elements, silicon carbide (SiC) heating elements, or high-temperature resistance wires, it enables stable sintering of zirconia dental materials. The system can also be equipped with sintering boxes for loading zirconia beads and zirconia blanks.

Features of PCW Shapes

  • Ultra-Low Shrinkage

    Maintains dimensional stability during high-temperature sintering cycles, reducing lining deformation.

  • Excellent Thermal Insulation Performance

    Effectively reduces heat loss and improves temperature control accuracy and energy efficiency.

  • Lightweight Structure

    Reduces furnace thermal mass, enabling faster heating and cooling response.

  • Custom-Shaped Design

    Can be individually designed according to furnace heating curves and chamber structures.

  • Good Mechanical Stability

    Suitable for repeated thermal cycling, maintaining structural reliability.

  • Shot-Free Structure and High-Temperature Resistance

    Ideal for high-temperature dental applications such as zirconia material sintering.
