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 effect of inoculation on properties of modified ductile Ni-resist alloy
Mohd Rashidi, Maarof; Mohd Hasbullah, Idris; Shayfull Zamree, Abd Rahim (Trans Tech Publications, 2014)In this study, ductile Ni-resist alloy with a minimum 18 wt. % nickel composition was modified. Up to 12 wt. % manganese was added together with 10 wt. % nickel before undergoing the inoculation process at various percentages ... -
Improving warpage on thin shallow parts in two-plate moulds with conformal cooling channels
Shayfull Zamree, Abd. Rahim; Muhammad Syahril, Bahari; Siti Aishah, Adam; Mohd. Nasir, Mat Saad; Nooraizedfiza, Zainon (Praise Worthy Prize S.r.l., 2013-03)Nowadays, the trend of consumer products designed is getting smaller and most of cover is made from plastic which was produced by using injection molding process. Thus, the demand of thin shallow plastic parts in global ... -
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 ... -
Milled groove square shape conformal cooling channels in injection molding process
Shayfull Zamree, Abd. Rahim; Safian bin Sharif, Prof. Dr.; Azlan, Mohd Zain, Dr.; Rozaimi, Mohd. Saad; Ahmad Fairuz, Mansor (Taylor and Francis Group, LLC., 2013-08)In designing molds for injection molding process, it is very difficult to achieve efficient cooling with uniform thermal distribution. To overcome these issues, the uses of conformal cooling channels with the uniform ... -
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 ... -
