Optimization of Injection Moulding Process Parameters in the Moulding of High Density Polyethylene (HDPE)
OSARENMWINDA, JO & OLODU, DD
Abstract
In this study, optimal injection moulding conditions for minimum shrinkage during moulding of
High Density Polyethylene (HDPE) were obtained by Taguchi method. The result showed that melting temperature
of 190OC, injection pressure of 55 MPa, refilling pressure of 85 MPa and cooling time of 11 seconds gave minimum
shrinkage for High Density Polyethylene. Cooling time was found to be the factor with most significant effect on
the shrinkage of High Density Polyethylene followed by refilling pressure. Injection pressure was found to be the
least effective factor.
