The base part of a piston assembly is shown below. The part outer dimensions are: length 76 mm width 64 mm, height 30 mm. The part volume is 29 cm and it is to be molded from ABS. The maximum wall thickness is 3.0 m FIGURE 8.19 Pneumatic piston assembly base part You have obtained a quote of 8,000 for a single-cavity mold for the part. However, large quantities of the part are required justifying the use ofa 4-cavity mold, which means for each injection cycle, parts will be produced. For the proposed 4-cavity mold production, estimate the following: a. The appropriate machine size from the selection in Table 8.4 (table for Injection Molding Machine), making an approximate allowance for the projected area of the runner system as well as the four cavities
b. The likely molding machine cycle time.
