  • Low Voltage Insulators: These items are small and are fired individually on kiln furniture shelves so they can be fired either in shuttle kilns or tunnel kilns.
  • High Voltage and Medium voltage Insulators: These items are generally much taller and thicker so they are usually supported with a tall SiC frame. This means that they are too tall and not stable enough to pass through a tunnel kiln so large Shuttle kilns are used. The large shuttle kilns can go as big as 500m3 with cold to cold firing cycles from 24 hours to 3 days depending upon the products.
