The influence of different mold temperature on warpage in a thin shallow injection molding process
(Praise Worthy Prize S.r.l., 2012)Every injection molding parameter have its own influence towards the quality of an injection-molded part. Temperature, pressure and time are main parameters that typically highlighted in controlling the warpage defect of ... -
Investigation on Nylon PA66 side arms using Taguchi and ANOVA analysis in reducing cost of producing urinary catheters
(Praise Worthy Prize, 2011-11)This article discusses on a research experience and finding based on a collaboration with a medical equipment manufacturer in producing urinary catheters. The manufacturer had been spending high cost yearly to replace more ... -
Optimal process conditions of warpage with thin-shallow features molded with pin-point gating system
(Praise Worthy Prize, 2011-11)Thin shallow plastic parts are widely produced using injection molding processes in producing varieties of components and applications. Warpage issue always happens in manufacturing thin shallow parts due to its uneven ... -
Optimization on parameter settings in determining warpage factors of a side-gated thin shallow part injection molding for PP, ABS & PC+ABS materials
(Praise Worthy Prize S.r.l., 2012-05)The injection molding process of thin shallow part requires several concerns in order to produce a quality output. In part of determining the best parameter settings, among other considerations that need to be taken are ... -
Potential of conformal cooling channels in rapid heat cycle molding: a review
(Wiley Periodicals, Inc., 2014)Rapid heat cycle molding (RHCM) can eliminate the weld line, increase flow length, and improve surface quality of the molded parts. However, the cycle time is much longer as compared to the conventional injection-molding ... -
A study on two plate and three plate mold of ultra thin plates in minimizing warpage issue
(Praise Worthy Prize, 2011-11)The demand of ultra thin plastic parts in global industries is increasing today. Ultra thin plastic parts are widely produced using injection molding processes and it is understood that warpage issue is regularly found in ... -
Warpage analysis between straight and conformal cooling channels on thin shallow shell
(Trans Tech Publications, 2014)Warpage is a type mold defect due to non-uniform temperature variation which causes differential shrinkage rate on the moulded parts. An accurate warpage prediction is so important in helping mould designers to achieve ... -
Warpage optimization on ultra thin plate in three plate mold for PP, ABS & ABS+PC materials by using Taguchi method
(Praise Worthy Prize S.r.l., 2012-03)The parameters setting of process conditions in injection molding process is very importance to ensure the quality of molded components is controlled by minimizing of any defects such as warpage. Various injection parameters ...
