Do you know the name of the process by which most
plastic solid materials are produced? It is called Injection molding.
It is a simple process. However, the process may require practice for
efficiency.
What is the process of Injection molding?
During the process of plastic injection molding, the plastic is
heated till it melts and is introduced, under pressure (injected), into
a mold. The mold may be made up of any metal such as steel or aluminum.
The molten form is then allowed to cool down and set into a solid form.
The plastic material thus formed is then retrieved out of the mold.
The
actual process of plastic molding is just an expansion of this basic
mechanism. The plastic is let into a barrel or chamber under gravity or
force-fed. As it moves down, the increasing temperature melts the
plastic. Then, the molten plastic is forcibly injected into the mold
under the barrel with an appropriate shape. As it cools, it solidifies.
The plastic molded like this has a reverse shape than that of the mold.
A variety of shapes both 2D and 3D, can be produced by the process. The
process of plastic molding is cheap due to the simplicity involved and
the quality of the plastic material is modifiable by changing the
factors involved in the custom injection molding process:
- The pressure of injection can be changed to change the hardness of the final product.
- The thickness of the mold also governs the quality of the article produced.
- The temperature for melting and cooling determine the quality of the plastic formed.
ADVANTAGES
The major advantage of injection molding is that it is very cost
effective and fast. Apart from this, unlike the cutting processes, this
process rules out any undesired sharp edges. Also, this process
produces smooth and finished products that require no further finishing.
