Answer:
Insufficient molten metal or obstruction in the system can cause defects in the casting. In this case, while pouring molten metal in the mould and molten metal does not appear in the riser, it can indicate two possibilities:
1. Insufficient molten metal to fill the cavity:
This can be caused due to various reasons such as improper gating system, improper pouring technique, and low pouring temperature. If there is insufficient molten metal to fill the cavity, the casting will have incomplete sections resulting in defects such as porosity, shrinkage, and cracks.
2. Obstruction between sprue and riser:
If there is an obstruction in the gating system, it can prevent the molten metal from reaching the riser. This can be caused by sand or debris blocking the flow, or the gating system is not designed correctly. If there is an obstruction, the casting will have a cold shut or misrun, which can result in scrap.
In conclusion, the absence of molten metal in the riser while pouring molten metal in the mould can indicate either insufficient molten metal to fill the cavity or an obstruction between sprue and riser. It is essential to identify the cause and take corrective actions to prevent casting defects.
