A flange (12) is arranged on a frame of the moulded part (1) for sealing against abutment a sealing surface (13). The shell (11) has a first permeability for a fluid and the flange (12) has a second permeability for the fluid. The second permeability is less than the first permeability.
Claims8
A molded part for a casting mold, comprising at least one shell for casting a product,
- wherein a flange for sealingly abutting a sealing surface is arranged on an edge of the shell, and
- the shell has a first permeability to a fluid and the flange has a second permeability to the fluid which is less than the first permeability, wherein permeability is defined as the volume of a fluid which can be passed through a solid per hour, per square decimeter and per pressure:
- I/(h*dm2*bar), and wherein
- the permeability of the shell is at least 10 I/(h*dm2*bar) and
- the permeability of the flange is maximum 1 I/(h*dm2*bar).
