Nutec Bickley has extensive experience designing and manufacturing
tunnel kilns and shuttle kilns for the Ceramic Core industry.


  • Firing/Sintering: High temperature heating is used to create strong chemical and ceramic bonds. If temperatures are very uniform then the fired product will be very close to dimensional tolerances and minimal final grinding will be required.
  • Burnout/Debindering/Debinding: During this low temperature process the organic binders and lubricants are burnt out of the body. Shrinkage can occur during this process so the temperature increase must be carefully controlled and each part of the core must be at the same temperature to reduce mechanical stresses. If the organics are removed too quickly or with the wrong kiln atmospheres then the product can be damaged.
