The problem with moulding equipment in jolt moulding can be avoided by implementing a squeeze method of ramming.
View Answer Explanation
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?
Sand slinging method is best, but the process takes too much time to accomplish the operation.
In sand slinging, which of the following parts is used for the spraying of moulding sand into the flask?
Which of the following is the simplest sand molding?
Which of the following is not an application of Open sand molding method?
Which method is used if the upper surface of casting is required to be smooth?
In bedded-in method, what shape does the upper surface of the casting have?
