Carbon-Carbon Composite Moulds

BZNCarbon offers custom-engineered carbon-carbon composite moulds designed for aerospace, industrial, and high-temperature tooling. Superior thermal resistance and extended service life.

Description

BZNCarbon specializes in the development and production of carbon-carbon composite moulds designed to operate under extreme conditions. These moulds are built using advanced fiber structures—2.5D, 3D, or 4D—with densities ranging from 1.5 to 1.9 g/cm³, depending on the specific performance and application requirements. Compared to conventional graphite moulds, our C/C moulds deliver enhanced durability, reduced thermal deformation, and longer operational life.

Whether you require intricate tooling for aerospace parts or high-strength moulds for furnace forming, BZNCarbon’s customized approach ensures optimal results across a variety of applications.


What Are Carbon-Carbon Moulds?

Carbon-carbon composite moulds are manufactured by reinforcing carbon fibers in multiple orientations and impregnating them with a carbon matrix. After high-temperature processing above 2000°C, the result is a lightweight, ultra-high-strength material that retains mechanical and thermal stability in harsh thermal environments.

These moulds offer significant advantages over graphite moulds, including superior flexural strength, lower oxidation rates (with protective treatment), and greater resistance to thermal cycling.

Oxidation Protection & Surface Coating

While carbon-carbon materials can begin to oxidize in oxygen-rich environments above 400°C, BZNCarbon offers multiple oxidation resistance strategies, including:

  • Matrix densification and surface passivation

  • Application of protective coatings to isolate C/C material from oxygen exposure

  • Optional surface treatments adapted to furnace atmosphere and use-case

Our oxidation protection technologies significantly prolong the life of moulds used in aerobic high-temperature applications.
