Moulds are tools into which melted plastic is poured, cooled and solidified to form and remove the moulded product.
STEP 1 Melt the plastic.
Injection moulding requires plastic to be melted.
However, plastics with large parts or complex shapes
can be difficult to melt.Therefore, to melt plastics, they are crushed into small pieces
or in a granulated state called pellets
When making chocolate confectionery, chocolate is crushed and then <a12> Tempering is done in the same way, isn't it?It's the same way.
STEP 2 Press the plastic in.
Melted plastic is very soft and can be poured into moulds. However, if the plastic is poured slowly, it will cool and harden in the process. An injection device like a syringe is then used to inject the plastic with great force. The mould is often made of metal and is called a die.
STEP 3 Chill the plastic.
The plastic in the mould gradually cools and hardens. The plastic can be removed from the mould as a moulded product within one minute After removal, the process of melting the plastic in (1) starts again, and is repeated in (2) and (3).
