Description

The graphite groove plate is an industrial plate made of graphite, with V, W and other grooves designed on the surface. These grooves help in positioning and supporting other materials during industrial processes or are used for fluid guiding and heat dissipation. Sizes and shapes can be customized according to different needs. Graphite groove plates are widely used in various industries, including semiconductor manufacturing, solar cell production, heat treatment furnaces, hard alloy sintering, chemical reactors, and powder metallurgy. In these applications, graphite groove plates can serve as support plates, heat dissipation plates, fixed bases, or reaction platforms to effectively improve the efficiency of the entire process and the quality of the products.

Features
  • High temperature resistance. Graphite can withstand extremely high temperatures, typically usable in environments exceeding 3000 °C without melting or significant deformation.
  • Corrosion resistance. Graphite has excellent resistance to most chemicals and is not easily corroded by acids, bases, or solvents.
  • Electrical and thermal conductivity. Graphite is an excellent conductor, and its superior thermal conductivity makes it an ideal choice for acting as heat dissipation materials.
  • Self-lubrication. Graphite has self-lubricating properties, which can reduce friction in applications, such as sliding contact surfaces in high-temperature or high-pressure environments.
  • Machinability. Despite its high hardness, graphite's layered structure makes it easy to machine into various shapes and sizes, including fine groove designs. This characteristic allows for the customization of graphite groove plates to meet specific industrial needs.
  • Low thermal expansion coefficient. Graphite has a relatively low thermal expansion coefficient, resulting in minimal changes in volume and shape with temperature fluctuations, ensuring dimensional stability of equipment during thermal cycles.
  • Wear resistance. Graphite material is wear-resistant, making it suitable for use in high-wear environments such as fluid handling and powder processing equipment.
