Pneumatic injection moulding machine is a project for mechanical students pursuing their graduation degree. Most of the mechanical projects are based on hydraulic and pneumatic systems as these are important theoretical topics of mechanical curriculum. The advantage of designing project based on hydraulic system and pneumatic system is that it will help you understand the concepts and logics well. In Pneumatically operated injection moulding machine moulding operation is done with the help of compressed air. These machines are cost-effective and more efficient for small scale and medium scale industries and finds uses in these types of industries. The problem of removing product manually from the moulding machine is overcome by designing this pneumatic injection moulding machine. Hence, it is a good choice of project for graduation students.
