Question

Simple cores of regular shapes and uniform cross-section can be extruded easily on a core extrusion process.

(a) True

(b) False

The question was asked in unit test.

The doubt is from Methods of Making Cores in division Sand Moulding of Foundry and Forging

Answer 1

The correct choice is (a) True

For explanation I would say: In a core extrusion machine, the spiral conveyor present is rotated and it forces the core sand through a die of specified shape only. Hence only simple cores of regular shapes and uniform cross section can be extruded from this process.
