Asyraf, Che Doi; Azmi, Harun (Universiti Malaysia Perlis (UniMAP), 2009-12-01)As a technical university which hands on practices are common to students, Universiti Malaysia Perlis (UniMAP) accommodates numbers of laboratories. From the basic fundamentals to the high-end laboratories, there might be ... -
Comparison between single and multi gates for minimization of warpage using taguchi method in injection molding process for ABS material
Mohd. Nasir, Mat Saad; Khairul Azwan, Ismail; Shayfull Zamree, Abd Rahim; Norshah Afizi, Shuaib (Trans Tech Publications, 2013-12)In this study, a mold is designed in single and dual type of gate in order to investigate the deflection of warpage for thick component in injection molding process. Autodesk Moldflow Insight software was used as a medium ... -
The influence of different mold temperature on warpage in a thin shallow injection molding process
Norshah Afizi, Shuaib; Muhamad Nasir, Murad; Mohd. Fathullah, Ghazli @ Ghazali; Shayfull Zamree, Abd Rahim; Muhamad Saifuldin, Abdul Manan, Dr. (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 ... -
Optimal process conditions of warpage with thin-shallow features molded with pin-point gating system
Mohd Fathullah, Ghazli@Ghazali; Shayfull Zamree, Abd Rahim; Norshah Afizi, Shuaib; Mohd Nasir, Mat Saad; Muhamad Saifuldin, Abdul Manan (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 of tile laying process parameters using taguchi's method
Norshah Afizi, Shuaib; Shayfull, Zamree Abd Rahim; Mohd. Fathullah, Ghazli @ Ghazali; Mohamad Ezral, Baharudin; Zaidi, Mohd Ripin (Praise Worthy Prize, 2011-11)This paper discusses the use of the Taguchi method of experimental design in optimizing process parameters of adhesion strength between tile and mortar bed. The effects of four process parameters of force, thinset mortar ... -
Optimization on parameter settings in determining warpage factors of a side-gated thin shallow part injection molding for PP, ABS & PC+ABS materials
Norshah Afizi, Shuaib; Muhamad Nasir, Murad; Mohd. Fathullah, Ghazli @ Ghazali; Shayfull Zamree, Abd Rahim; Muhammad Syahril, Bahari (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 ... -
Strength of the weld line and warpage defects on the molded parts in injection molding process
S. M., Nasir; Khairul Azwan, Ismail, Dr.; Shayfull Zamree, Abd Rahim; Norshah Afizi, Shuaib (Praise Worthy Prize S.r.l., 2013)Strength at weld the line location and warpage problem in injection molding plastic component were not new problems in injection molding industries. Many researchers had emerged with several improvement techniques to reduce ... -
Warpage analyses on thin plate in three-plate mold by Taguchi method and analysis of variance (ANOVA) for PC, ABS and PC/ABS
Shayfull Zamree, Abd Rahim; Mohd. Fathullah, Ghazli @ Ghazali; Mohd. Nasir, Mat Saad; Norshah Afizi, Shuaib; Muhamad Saifuldin, Abdul Manan, Dr. (Praise Worthy Prize S.r.l., 2012)Warpage is a common issue in plastic injection molding process. It can get worse for thin parts and therefore it is more challenging for product design engineers, mold designers and manufacturing engineer to cope with ... -
Warpage analysis between straight and conformal cooling channels on thin shallow shell
Norshah Afizi, Shuaib; Mohd Fathullah, Ghazli@Ghazali; Shayfull Zamree, Abd. Rahim; Mohd Nasir, Mat Saad; Mohd Fidzwan, Md Amin Hamzas (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 ... -
