Advantages

Ceramic cores occupy the space that cannot be reached, filled or dried with the ceramic shell in investment casting (slip). Ceramic cores are used for exactly these cavities in investment castings. This process is a cost-effective alternative to often time-consuming post-processing steps.

In some cases, it is not possible to demould the core in one piece after moulding due to the need for undercuts. It is possible to create several core parts individually and join them together with a special ceramic adhesive to form a core. In order to achieve precise transitions, glue gauges or registration marks are used.

Advantages and possibilities of ceramic cores at an overview:
Feasibility of castings and core bearings
Diverse design options
Complicated hollow spaces
Low wall thicknesses
Tight tolerances
Curved channels
Thin slits
Very good surfaces
Easy release of the core
Precise repeatability
Mechanical processing on the casting is no longer necessary
Economic design
Compatible for special material groups
Guarantee the shape, remain in the shell until the end of the process

CERAMIC CORES

Quality, advantages, possibilities and tolerances of the ceramic cores.

Ceramic cores offer many advantages and possibilities in terms of design freedom, increased productivity and cost savings.

  1. Quality:

    1. At and after each production step, the cores are checked and documented.
    2. Calipers, gauges and scans are used to guarantee the dimensions.
    3. Batches are traceable.
    4. Initial sampling, test specifications and acceptance regulations are agreed with the customer before the order is awarded.
    5. Reports are sent to the customer.

Tolerance Range

Quality & tolerances of ceramic cores
In principle, also for economic reasons, it is always important to strive for the greatest tolerable tolerance.

Our K tolerances are 50% of the D tolerances (according to P690).

Other tolerance specifications can be agreed in advance and checked for feasibility.
