2) The eccentric wheel shown below is used in vibration feedback generation units such as those used in game controllers. Therefore, production volumes have to be very high and the part has to have good tolerances to provide consistent performance. i) A die casting operation is proposed for fabricating a small number of prototypes. Should a two or three part die be used? In the figure, draw the parting plane(s) for the mold pieces. ii) What production method should be used for regular production? Explain.

Solution

1. a two part die will be sufficient for making the above mentioned product. Since it has symmetry and height of all the raised parts in the product is same. therfore there is no need for 3rd die.

2. closed die forging can be used to form this part effectively and at large production rates also.
