Optimization of injection moulding process parameters in the moulding of High Density Polyethylene (HDPE)

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...

A Model of the Injection Moulding Process

This paper is concerned with the injection moulding process, in which hot molten plastic is injected under high pressure into a thin cold mould. Assuming that the velocity and temperature profiles across the mould maintain their shape, a simple steady state model to describe the behaviour of a Newtonian fluid during the rilling stage is developed. Various phenomena of the process are examined, ...

Lattice Boltzmann Modeling of Injection Moulding Process

Polymer injection in moulds with complicated shapes is common in todays industrial problems. A challenge is to optimize the mould design which leads to the most homogeneous filling. Current commercial softwares are able to simulate the process only partially. This paper proposes a preliminary study of the capability of a two-fluid LatticeBoltzmann model to provide a simple and flexible approach...
