    • 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 ...
    • 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 ...
    • 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 ...
    • Application of Firefly Algorithm for Parameter Estimation of Damped Compound Pendulum 

      Mohd Sazli, Saad; Mohamad Izzat, Kamal; ‪Shayfull Zamree, Abd Rahim‬; Mohd Nasir, Mat Saad; Mohd Fathullah, Ghazli @ Ghazali (EDP Sciences, 2016)
      This paper presents an investigation into the parameter estimation of the damped compound pendulum using Firefly algorithm method. In estimating the damped compound pendulum, the system necessarily needs a good model. ...
    • Shrinkage analysis on thick plate part using Response Surface Methodology (RSM) 

      M. Isafiq; Shayful Zamree, Abd Rahim; ‪Mohd Nasir, Mat Saad; M., M. Rashidi; Mohd Fathullah, Ghazli @ Ghazali; Nik Noriman, Zulkepli (EDP Sciences, 2016)
      The work reported herein is about an analysis on the quality (shrinkage) on a thick plate part using Response Surface Methodology (RSM). Previous researches showed that the most influential factor affecting the shrinkage ...
    • Parameter estimation of damped compound Pendulum using Bat Algorithm 

      Mohd Sazli, Saad; Luqman Nul Hakim, Mat Deri; Shayfull Zamree, Abd Rahim; Mohd Nasir, Mat Saad; Mohd Fathullah, Ghazli @ Ghazali (EDP Sciences, 2016)
      In this study, the parameter identification of the damped compound pendulum system is proposed using one of the most promising nature inspired algorithms which is Bat Algorithm (BA). The procedure used to achieve the ...
    • Analysis of Strength on Thick Plate Part using Genetic Algorithm Optimisation Method 

      S., M. Azlan; Shayful Zamree, Abd Rahim; Mohd Nasir, Mat Saad; Mohd Sazli, Saad; M., M. Rashidi; Mohd Fathullah, Ghazli @ Ghazali (EDP Sciences, 2016)
      This study focuses on the optimisation of the injection moulding parameters to maximise the strength ofmoulded parts using a simulation software. The moulded parts were injected with Acrylonitrile- Butadiene-Styrene (ABS) ...
    • 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 ...
    • Optimisation of Shrinkage and Strength on Thick Plate Part Using Recycled LDPE Materials 

      Norshahira, Roslan; Shayfull Zamree, Abd Rahim; Abdellah El-hadj, Abdellah; Mohd Mustafa Al Bakri, Abdullah; Błoch, Katarzyna; Pietrusiewicz, Paweł; Nabiałek, Marcin; Szmidla, Janusz; Kwiatkowski, Dariusz; Correia Vasco, Joel Oliveira; Mohd Nasir, Mat Saad; Mohd Fathullah, Ghazali (MDPI AG, 2021-04-05)
      Achieving good quality of products from plastic injection moulding processes is very challenging, since the process comprises many affecting parameters. Common defects such as warpage are hard to avoid, and the defective ...
