Vacuum Formed Shapes

Vacuum Formed Shapes

Ceramic fiber vacuum formed shapes are made of high-quality ceramic fiber bulk by adopting the technique of vacuum forming. The purpose of making these products is to meet the special requirements of insulation in industrial field. Various products need to have specialized molds according to their unique shape and size for meeting customers’ requirements. All formed shapes have a lower shrinkage within applicable temperature, and can maintain the characteristics such as insulation, lightweight, etc. During the period of using the products, they won’t be eroded by lots of molten metal. 

Applications

  • Observation of industrial furnace.
  • Industrial furnace burner, door.
  • Plug and launder of Aluminum Products Industry.
  • Lining refractory of high-temperature laboratory furnace.
  • Thermal insulation of domestic and industrial heating devices
  • Non-ferrous metal melting tank padded, casting riser.
  • Roller furnace insulation bricks
