Application of RSM to optimise moulding conditions for minimizing shrinkage in thermoplastic processing
Mohd Nasir, Mat Saad; Khairul Azwan, Ismail; Shayfull Zamree, Abd Rahim (Trans Tech Publications Ltd, 2016)This study focuses on the analysis of plastic injection moulding process simulation using Autodesk Moldflow Insight (AMI) software in order to minimize shrinkage by optimizing the process parameters. Two types of gates ... -
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 ... -
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 ... -
Improving warpage with milled groove square shape conformal cooling channels
Shayfull Zamree, Abd Rahim, Dr.; Safian, Sharif; Azlan Mohd, Zain; Mohd Nasir, Mat Saad; Rozaimi, Mohd Saad (Trans Tech Publications Ltd, 2016)Warpage is a common issue in an injection moulding process due to non-uniform temperature variation causing differential shrinkage on the moulded parts. In designing moulds for injection molding process, it is very difficult ... -
A new invention of alarm reminder locking (ARL) security system
Mohd Effendi, Muhammad Suandi; Shayfull Zamree, Abd Rahim; Mohd Sazli, Saad; Mohd Nasir, Mat Saad; Badrul Azmi, Abdul Holed (Engg Journals Publications, 2016-02-01)Alarm Reminder Locking (ARL) Security System mainly focuses on a door security system, which can install in the door area to increase the security level for home, office room, hostel or other places. This system used Arduino ... -
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 ...
