Abstract

This apparatus is used for casting green ceramic substrates. Cavity 1 of shaped, flexible mold member 2 is filled with ceramic paint in the configuration of the desired substrate 3. After partial curing of the paint, the desired apertures in the substrate are formed by lowering carrier plate assembly 4. The latter has projecting pin members 5 attached to it. Plate 4 also includes an apertured stripper plate 6 mounted for movement on pins 5 and normally positioned against carrier plate 7.

Casting of Green Ceramic Substrates

This apparatus is used for casting green ceramic substrates. Cavity 1 of shaped, flexible mold member 2 is filled with ceramic paint in the configuration of the desired substrate 3. After partial curing of the paint, the desired apertures in the substrate are formed by lowering carrier plate assembly 4. The latter has projecting pin members 5 attached to it. Plate 4 also includes an apertured stripper plate 6 mounted for movement on pins 5 and normally positioned against carrier plate 7.

When plate 4 is lowered, pins 5 press into mold 2 through and beyond the depth of green substrate 3. After curing of substrate 3, plate 6 is lowered and pins 5 are withdrawn from substrate 3. This is effected by raising plate 7 leaving the desired pattern of holes in substrate 3. The finished substrate 3 is removed from cavity 1 by flexing member 2.

Alternatively, the finished substrate 3 can be removed from the mold on pins 5 of carrier plate 7 as it is raised and then released from pins 5 by plate 6.
