mechanism works. |
|
1. What materials could be used to manufacture the body of the duck / mechanical toy ? |
|
2. What are the properties of the material you have chosen ? | |
3. Name an alternative material that could be used to manufacture the body of the duck / mechanical toy ? |
|
4. What are the properties of the alternative material you have chosen ? | |
5. A manufacturer is hoping to make hundreds of the mechanical duck from a plastic material using ‘blow’ moulding as the process. |
|
5A. Name a suitable material for use in the process blow moulding: | |
5B. Why have you chosen this material? | |
