Description
1. Its main use is to make standard sample for strenght tester and
air permeability tester.
2. The sample is used to determine the compaction of the molding
sand.
3. Samples of various standard geometries can be prepared for
testing of foundry sands and mixtures
4. The sample was prepared by using a sample box (barrel) of
various standard geometries, and placing an appropriate amount of
molding sand
or mixture in a box (barrel) and applying a impact energy impact of
1 kg.
5. The structure is composed of a base, a size cam, a weight, a
punch, a scale and the like.
