Graphite Cluster Wheel: A Key Accessory in the Glass Fiber Industry

  • Excellent chemical & thermal stability.
  • Outstanding corrosion resistance and good oxidization resistance.
  • High thermal conductivity and low coefficient of thermal expansion.
  • High termal shock resistance and stable quality.
Many graphite cluster wheels in different sizes

Graphite cluster wheel, also known as graphite oiling roller, is an accessory used in the textile machines. It is typically used in the glass fiber industry for the traction and transmission of glass fiber yarns. Its smooth surface helps to reduce the friction in the traction and transmission process, thereby reducing the loss and breakage of yarns.

In addition, graphite cluster wheel can withstand high temperature and high pressure, which is very important for the glass fiber industry as its processes often require to be carried out under high temperature and high pressure conditions.


Graphite cluster wheel has high strength, high density, high purity, excellent self-lubrication, high temperature resistance, corrosion resistance, thermal shock resistance, good oxidization resistance, low impurity content and long lifespan, and is widely used in the glass fiber industry.

  • Thermal stability. Specially design is carried out according to the rapid heating and cooling conditions of graphite molds to ensure the reliability of product quality.
  • Corrosion resistance. The uniformly dense matrix design delays the degree of corrosion of the graphite mold.
  • Impact resistance. Graphite can withstand high thermal shock intensity, so any process can be safely carried out.
  • High thermal conductivity. High fixed carbon content ensures good thermal conductivity, shortens melting time, and significantly reduces energy consumption.
  • Metal contamination control. Strict control of material composition ensures that the graphite mold does not pollute the metal during melting.
  • Quality stability. The production technology and quality assurance system of high-pressure molding fully guarantee the stability of quality.
