Optimization of Injection Moulding Process Parameters in the Moulding of Low Density Polyethylene (LDPE)

Injection moulding is one of the most popular polymer processing methods due to its high production rate as well as its ability to produce very intricate geometries at very cheaper cost and within few seconds. There are several flaws which occur while producing plastic parts by Injection moulding, like warpage, shrinkage, flash, sink marks etc. Shrinkage is one of the most critical problems whi...

Simulation Tools for Injection Moulding

In this paper the concern is certain simulation tools for the lling phase of injection moulding of plastics. A mathematical model, called the distance model, of the injection moulding process has been developed by Professor Gunnar Aronsson at the University of Linkk oping. From this model one can nd the lling pattern (i.e. ow fronts) of the molten polymer as it enters the mould, by solving a sh...

Effect of Runner Dimensions on Cavity Filling in Micro- Injection Moulding for Defect-free Parts

Modelling and simulation of injection moulding process is an important technique that could shorten production cycle time with improved productivity for defect-free parts. This technique is more suitable for micro-injection moulding (μIM) process as likely defects during production can be predicted. Therefore, this study aims to investigate the effect of runner dimensions on quality of moulded ...
