At what distance should the gagger be kept from the pattern?
View Answer Explanation
Hand rammer is made up of metal.
Which of the following processes is the first step involved in the sand casting?
It is possible to provide any kind of internal features to the casting by the help of pattern.
In mould making process, moulding time is greatly affected by the shape and size of the casting components.
In mould making process, clamping is basically done to prevent any loss of material from the moulding box.
It is not possible to estimate solidification time by considering the wall thickness and temperature of the casting metal.
During the pouring process, filling time of molten metal should be short to avoid early solidification of the casting.
The process shakeout is generally referred to escaping of gases from the molten casting during the solidification.
Quick solidification of the casting can cause defects like shrinkages, cracks or blow holes.
Shot blasting operation is mainly done to identify the type of defects in the casting part.
