Development and Structural Analysis of Injection Moulding-Hydraulics Clamping Unit Testing System

Abstract

This project is focusing on the development of a test unit for the hydraulically driven clamping system, typically used in injection moulding. The objectives of this project are to fabricate the model of clamping unit and to perform structural analysis based on the model design through simulation and by performing actual experiment on the real fabricated model. This actual test was conducted by compressing the load cell in between the two moulds halves in order to get the clamping force value through the data logger. The results obtained from simulation shows that the maximum stress of clamping unit with tie bar can achieve up to 11.2 MPa, with the safety value of 2.5. In the other hand, for the actual test experiment, the result the maximum clamping force produce is 3160N at 52bar of pressure. These values are important to be used as guidance in selecting the suitable injector part. As a conclusion, this clamping system has work properly and efficiently to be used for further research and a tool to understand more about the mechanism and the effects of clamping units in injection moulding process.
