Big cores are set in molds by hand.
View Answer Explanation
Cores are generally made of relatively low strength for better utilization in the production of castings.
Dry sand cores are widely used in the injection moulding process for casting various polymers.
Green sand cores are not suitable for producing very complex shapes of castings.
Core prints are generally provided on the mould for easy removal of cores from the moulding box.
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.
