The mould designed has made it possible to produce high
quality warpage testing specimen to determine parameters
that affect warpage. The testing specimen was produced at
low cost and involves only little finishing that is de-gating.
The thermal analysis of plastic injection mould has provided
an understanding of the effect of thermal residual stress
on deformed shape of the specimen and the tensile stress analysis
of product managed to predict the tensile load that the
warpage testing specimen can withstand before experiencing
failure
