High Fracture Toughness 99% Al2O3 Ceramic Products
1. Description:
Our cores are a critical component in the manufacture of complex castings for aircraft engine turbine blades, vanes and associated cast components. They can also be used to produce a wide range of products from valve components to industrial turbine blades, to create cavities and features with precision, whilst reducing the costs of machining parts.Our injection moulded ceramic cores can also be utilised within the automotive industry in order to replace sandcasting processes where required. Sandcasting methods are not as accurate, in terms of tolerances, as ceramic cores and do not provide a smooth finish on the final product. These two major problems can be eradicated easily with the use of ceramic cores.
