INTRODUCTION FOR PRODUCT DESIGN & MATERIAL SELECTION
This course is created for designer to gain a strong fundamental knowledge of product design and how product design will influence part performance & mouldability. Participant will also learn various methods that can be used for plastic parts assembly design.
Moreover, the course also emphasize how plastic material properties will influence on materials selection. It also cover the properties of plastic materials & their testing methods to meet the design specifications.
The course instructor will draw on his extensive experience to illustrate the subject matter with practical examples.
