Radhwan, Hussin; Safian, Sharif; Nabiałek, Marcin; Shayfull Zamree, Abd Rahim; Mohd Tanwyn, Mohd Khushairi; Mohd Azlan, Suhaimi; Mohd Mustafa Al Bakri, Abdullah; Mohd Hazwan, Mohd Hanid; Wysłocki, Jerzy J.; Bloch, Katarzyna (MDPI AG, 2021-02)The mold-making industry is currently facing several challenges, including new competitors in the market as well as the increasing demand for a low volume of precision moldings. The purpose of this research is to appraise ... -
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 ... -
Potential of conformal cooling channels in rapid heat cycle molding: a review
Shayfull Zamree, Abd Rahim; Safian, Sharif; Azlan, Mohd Zain; Rozaimi, Mohd Saad; Mohd Fathullah, Ghazli@ Ghazali (Wiley Periodicals, Inc., 2014)Rapid heat cycle molding (RHCM) can eliminate the weld line, increase flow length, and improve surface quality of the molded parts. However, the cycle time is much longer as compared to the conventional injection-molding ...
