Abstract: Injection moulding machine is one of the most widely used method for conversion of plastics into various end products application to wide range of plastic material. The main principle is to compress the plastic material in a heating chamber (barrel) with the help of plunger and induction coil convert plastic polymer into molten (semi-solid) state. Then the plastic polymer in predetermined quantity is forced through the nozzle into the die under pressure. After completing the process, final product is obtained from the die. We can use plastics, metals or alloys for this process. In our project we are using plastics polymers for making bushes, switches, fishing hooks, mobile covers etc. This machine is a prototype for producing small plastic components. This injection moulding machine is very useful for the small scale industries because of its low manufacturing cost, low maintenance cost, no skilled worker is required. It can be recommended for small scale investors those who are willing to produce small plastic products.

The describe an injection molding machine, which is a widely used method for converting plastics into various end products. The machine operates by compressing plastic material in a heating chamber using a plunger and induction coil, transforming it into a molten state. The molten plastic is then injected under pressure through a nozzle into a die, resulting in the formation of the final product. The process can utilize plastics, metals, or alloys. The described machine is a prototype designed for producing small plastic components such as bushes, switches, fishing hooks, and mobile covers. It offers benefits such as low manufacturing and maintenance costs, as well as not requiring skilled labor. As a result, it is recommended for small-scale industries and investors looking to manufacture small plastic products.
