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 ... -
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 ...
