Which of the following processes of moulding is widely used for the manufacturing of bottle caps and automotive dashboards?
View Answer Explanation
Complex shape of parts or components cannot be formed by the injection moulding process.
Components from injection moulding process are made very expensive due to the application of very costly equipment.
The three mould technique is generally preferred than the two mould technique in injection moulding process.
Which of the following cooling systems is used in injection moulding process to increase solidification rate of components made?
The moulding directions in injection moulding can affect the cost of equipments used in the process.
The flow of plastic in the mould cavity is more proper and smooth if the thickness of the component made is very small.
Shrinkage of the plastic parts in mould cavity can results in generation of sink holes in the plastic.
A heavy surface finishing is always required for components made in injection moulding machine.
In injection moulding process, ribs are generally provided for the reinforcement to avoid sink marks from the component.
In blow molding, to inflate soft plastic, which medium is used?
