I am the youngest girl in the factory.
Today we are going to talk about a common casting defect - multi meat defect.
Flying wings, burrs, lifting boxes, bulging boxes,
meat, these are "meat defects"
The main prevention measures for meat defects are as follows:
(one) Reasonable layout, prevent blowing sand is not solid,
prevent lifting box and mold
(two) Adjust the sand mixing process, control the moisture,
improve the strength of molding sand;
(three) reasonable sand granularity and refractoriness to prevent veins;
(four) Reasonable tooling design to ensure reasonable clearance;
(five) Tooling management should do a good job in module life management;
(six) When direct external cooler is required, the contact surface between
the external cooler and the casting must be polished and smooth;
(seven) Reasonable flow system design to prevent the metal liquid sand
and paint to wash away the casting meat;
Follow me, the youngest girl in the factory.
See you next time
