Ramming Mold Boxes Methods Questions and Answers -

Explanation: In sand slinging, we will obtain uniform strength throughout the mold because localized ramming of sand takes place because of throwing the small-small amount of sand into the mold box at the same amount of force. But in other processes strength will be more at the top or bottom or middle.

Automatic Pneumatic Sand Ramming Machine Mechanical Project

This Machine is used for Sand Ramming in Casting Process. A sand rammer is a piece of equipment used in foundry sand testing to make test specimen of molding sand by compacting bulk material by free fixed height drop of fixed weight for 3 times. It is also used to determine compactibility of sands by using special specimen tubes and a linear scale.

5) Sand is then tightly packed in the drag by means of hand rammers. Peen hammers (used first close to drag pattern) and butt hammers (used for surface ramming) are used. 6) The ramming must be proper i.e. it must neither be too hard or soft. Too soft ramming will generate weak mould and imprint of the pattern will not be good. Too hard
