What is the disadvantage of hand molding?(a) Damage to the projections(b) Costly method(c) Non-uniform strength(d) Poor surface finish of the mold |
|
Answer» Correct choice is (c) Non-uniform strength The explanation: In hand molding, the ramming force required for compressing the molding sand is applied by human hand. A human knows about projection in the pattern accordingly he applies force thus no damage to projections. Surface finish obtained is also good. But, the force applied is non-uniform which results in non-uniform strength. |
