Abstract: The injection moulding process is widely used to manufacture the products made from thermoset and
thermoplastic materials. The advancements in the manufacturing process is the main focus of many researchers. The
main aim is to make the products with accuracy and increase the production rate. In this paper we have worked on to
make the system automated using microcontroller and made the vertical moulding machine to use the earth’s gravity
to fill the cavity of the mould in short time and to increase the production rate.
Keywords: Injection Moulding, Servomechanism, Microcontroller.
Introduction
To manufacture the parts made from plastic material, injection moulding process is widely used in
industries. The products manufactured by this process can be small like bottle caps, toys and can be big as
well like milk crates and bins. The only thing to be taken care that how precisely these products are made.
If there is a small error during the manufacturing it will lead to a big loss to the manufacturing industry
because no one is going to buy the product. In the contemporary world, the research is being done to
manufacture the product with minimum human intervention. The computer-controlled production leads to
good precision and better quality [1], [2].
Injection moulding process is used to produce parts made from both thermoset and thermoplastic materials.
In the injection moulding process, the material is heated in the barrel and then is fed to the injection
moulding machine and is filled in the cavity where it cools down and take the desired shape of the cavity.
The small granular thermoplastic materials are used to shape into the desired product [3]. A typical
moulding machine consist of injection, hydraulic, mould, clamping and control system which is shown in
Figure 1.

Jain et al. [4] analysed the effects of process parameters They used Taguchi Approach to optimise these
parameters by using two level factorial design. Their investigation was related to shrinkage and warpage in
in the products prepared using injection moulding process. Guo et al. [5] proposed a mathematical model
which is used to optimise the parameters like melt, coolant and mould temperature, injection time and
switch over. They used fractional factorial design approach to optimise these parameters. Moon and Choi
