In the sand slinging process we can?t use a pattern with extension or projection.
View Answer Explanation
Which of the following methods of ramming is suitable for the small batch production of castings?
Which of the following parts is used in jolt moulding to ram the sand in mould?
Jolt method of ramming makes smooth ramming and packing of sand layers in the mould.
The jolt method of ramming can be suitable for horizontal surfaces in the mould.
The method of jolt ramming operates very leniently with the moulding equipment.
The problem with moulding equipment in jolt moulding can be avoided by implementing a squeeze method of ramming.
In squeeze ramming, hardness achieved is inversely proportional to the pressure applied on the squeeze plate.
In squeeze ramming, plate is always provided with a contour to achieve a better hardness of the sand.
Squeeze ramming is best for big castings and mainly suitable for high depth flasks.
Which of the following is the best method for the uniform ramming of moulding sand?
