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 ... -
Warpage analysis with straight drilled and conformal cooling channels on front panel housing by using taguchi method
Shayfull Zamree, Abd Rahim; Safian, Sharif, Prof. Dr.; Azlan, Mohd Zain, Dr.; Rozaimi, Mohd Saad; Ahmad Fairuz, Mansor (Trans Tech Publications, 2014)The challenging in injection molding process is to get the uniform thermal distribution on the molded parts during the cooling stage which is mainly depend on the design of the cooling channels in injection mold. Poor ... -
Warpage optimisation using Recycled Polycar-bonates (PC) on Front Panel Housing
Nur Aisyah Miza, Ahmad Tamizi; Abdellah El-hadj, Abdellah; Mohd Mustafa Al Bakri, Abdullah; Nabiałek, Marcin; J. Wysłocki, Jerzy; Jeż, Bartłomiej; Palutkiewicz, Paweł; Rozyanty, Abdul Rahman; Mohd Nasir, Mat Saad; Mohd Fathullah, Ghazli (MDPI AG, 2021-03-15)Many studies have been done using recycled waste materials to minimise environmental problems. It is a great opportunity to explore mechanical recycling and the use of recycled and virgin blend as a material to produce new ... -
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 ...
