    • 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) ...
    • 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. ...
    • 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 ...
    • Improving the quality and productivity of molded parts with a new design of conformal cooling channels for the injection molding process 

      Shayfull Zamree, Abd Rahim; Safian, Sharif; Azlan, Mohd Zain; Mohd Nasir, Mat Saad; Rozaimi, Mohd Saad (John Wiley and Sons Inc., 2015)
      In materials processing, quality and productivity are notably important and must be controlled for each product type produced. In the injection molding process, quality is measured as the extent of warpage of molded parts ...
    • 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 ...
    • Optimal process conditions of warpage with thin-shallow features molded with pin-point gating system 

      Mohd Fathullah, Ghazli@Ghazali; Shayfull Zamree, Abd Rahim; Norshah Afizi, Shuaib; Mohd Nasir, Mat Saad; Muhamad Saifuldin, Abdul Manan (Praise Worthy Prize, 2011-11)
      Thin shallow plastic parts are widely produced using injection molding processes in producing varieties of components and applications. Warpage issue always happens in manufacturing thin shallow parts due to its uneven ...
    • 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 ...
    • 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 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 ...
