Abstract

The efficiency of the ‘Injection molding Machine’ lies in the proper designing of screw feeder mechanism. The screw feeding mechanism needs to be setup differently for different materials, molds etc. The proper design includes the work from selecting the appropriate materials, designing for the optimum design, analysis of the designed parts at different flow rates, speed and temperatures. There are various parameters that govern the efficiency of the ’Injection molding Machine’. These parameters include ‘Filling Pressure’, ‘Mold Surface Temperature’, ‘Raw Material Melting Temperature’, ‘Filling Time’ etc.

Highlights

Injection Molding Machine are known for their adaptability in manufacturing sector
The initial design of the screw feeder of the injection moulding was studied and based on that it was redesigned with respect to dimensions and material to gain a control over the output
The analysis was performed on the designed screw feeder to check or verify its functioning under working conditions

Summary

Introduction

Injection Molding Machine are known for their adaptability in manufacturing sector. It can be used for mass production and obtaining highly precise manufactured parts.Injection molding is a method of manufacturing a plastic product from powdered thermoplastics by supplying the material through hopper to a heated chamber in order to make it easy to mold and force the material into the mold by the using the screw. Injection Molding Machine are known for their adaptability in manufacturing sector. It can be used for mass production and obtaining highly precise manufactured parts. Injection molding is a method of manufacturing a plastic product from powdered thermoplastics by supplying the material through hopper to a heated chamber in order to make it easy to mold and force the material into the mold by the using the screw. In this whole process pressure should be persistent till the material is hardened and is ready to be detached from the mold. This is the most common and preferred way of producing a plastic products with any complexity and size.
