Homework - Rotational Moulding

Rotational moulding is a process used to make hollow plastic products. E.G - Bins, canoes, floats etc.

There are three main steps to rotational moulding

Step 1 - The plastic is poured into the mould (powdered or liquid form)
The plastic is weighed and poured into the mould ready to be heated.

Step 2 - The heat is turned on
Whilst the mould is heating up, it starts to rotate to make sure all the plastic is dispersed equally.

Step 3 - Cooling down
The mould is taken from the oven to cool down. Air blows and mist of water slowly cools the mould.


Benefits from rotational moulding

• No plastic is wasted
• Fast manufacturing times (lowers the cost)
• The products come in different colours and styles.
