ABSTRACT
The injection molding is a manufacturing technique for making parts from both
thermoplastic and thermosetting plastic materials in production. Molten plastic is injected
at high pressure into a mold, which is the inverse of the product's shape. From the
previous data that had been taken, there are increasing rejected part. By using the
classical method, it can reduce the rejected value. This study will research to provide a
high level review and analysis of the governing principles to identify theoretical limits on
process performance. The variations in the machining parameters, such as temperature,
time, pressure, and distance greatly affect the measures of the machining performance.
Therefore, proper selection of the machining parameters can result in better machining
performance. After conducting an analysis for these parameters, which is the main factor
of the rejected value increased one solution from the aspect machine scale already
approachable and its value already at the optimum level. From the new parameter setting,
which is the optimum range value, one experiment was carried out on these machines and
finally it is shown that the rejected values are decreasing.

ABSTRAK
“Injection Molding” merupakan teknik pembuatan untuk menghasilkan bahagian-
bahagian tertentu daripada kedua-dua bahan termoplastik dan termoset di dalam bidang
pengeluaran. Cairan plastic disuntik ke dalam acuan pada suhu yang tinggi di mana acuan
tersebut menghasilkan bentuk produk. Mendapati wujudnya peningkatan penghasilan
bahan yang rosak sepanjamg pengeluaran produk ini. Penggunaan Classical Method ini
adalah bertujuan untuk menyelesaikan masalah dalam mengurangi jumlah bahan yang
rosak. Kajian ini akan melakukan analisa untuk menyediakan penilaian tahap tinggi dan
penganalisaan tentang prinsip utama dalam menentukan had teori dalam prestasi sesuatu
proses. Kepelbagaian dalam parameter mesin contohnya suhu, masa, tekanan dan jarak
sudah pasti memberi kesan pada pengukuran prestasi pemesinan. Oleh itu, pemilihan
parameter mesin yang tepat akan menghasilkan keputusan yang lebih baik ke atas
prestasi mesin. Setelah menjalankan analisis terhadap parameter yang menjadi faktor
utama dalam masalah bahan rosak ini, satu penyelesaian dari segi skala mesin telah dapat
ditemui dan nilainya telah pun berada pada tahap yang optimum. Daripada skala mesin
yang optimum tersebut satu ujikaji telah dijalankan pada mesin dan mendapati nilai
kerosakkan produk dapat dikurangkan.

ACKNOWLEDGEMENT
In the Name of Allah The Most Gracious, Most Merciful,
First of all, thanks to Allah S.W.T. to give me chance and strength to accomplish
the research of my final year project.
Special thanks to Mr. H. Haery IP, lecturer of the Faculty of Manufacturing
Engineering, University Technical Malaysia, Melaka as being my supervisor for my final
year project 1 and 2. I also would like to thanks to Pn. Rohana Bt. Abdullah as being my
second supervisor for my final year project. I would like to express my greatest gratitude
to my both supervisor, for his valuable guidance and continuing support throughout the
entire course of my work.
Finally, last but not least, I would like to thank my family and friends for all the
encouragement and for giving me support all the way.
