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 ... -
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 ... -

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 optimization on ultra thin plate in three plate mold for PP, ABS & ABS+PC materials by using Taguchi method
Mohd. Nasir, Mat Saad; Norshah Afizi, Shuaib; Shayfull Zamree, Abd. Rahim; Mohd. Fathullah, Ghazli @ Ghazali; Nooraizedfiza, Zainon (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 ...
