18 Moulding Sand Properties: Permeability, Cohesiveness

Permeability ∝ size of the grain. Excess use of clay reduces permeability during the sand casting process. Permeability property also depends on ramming. Ramming is a method of compacting sand. Hard ramming reduces overall spaces between the grains making mould more compact. Hard ramming reduces the permeability of sand mould.

Falling head permeameter

Used to determine the permeability of fine-grained soils such as clay-like or silty soils. The specimen is confined within the permeameter which is connected to the manometer tube filled with water. The sample must be completely satured with water before the test, and the operator will check the rate of fall of the water in the tube passing through the test specimen.

Mold Hardness Vs Permeability | PDF

This document discusses the relationship between mold hardness, permeability, and gas escape in sand casting molds. Several key points are made: 1. Mold hardness depends on factors like the binder system and quality of the mixed sand. Permeability depends more on the sand properties like size distribution and amount of fines. 2. There is no direct relationship between mold …
