Core prints are generally provided on the mould for easy removal of cores from the moulding box.
View Answer Explanation
It is not necessary for the chaplets to be of the same material as the material being casted in the mould.
Optimized design of chaplets is very necessary for the application of chaplets in supporting the cores.
For the removal of cores from the moulding box, caustic bath can be used which is very fast in processing the large and complex cores.
For removing cores from the castings, the hydraulic cleaning method is much safer than the method of caustic bath.
Core wires and rods can be used for removing the core mass from the casting part.
