You wish to injection mold an iPhone case out of ABS. The case is 15 cm long, 7 cm wide and 0.5 cm thick. Model the shape as a flat plate that is injected over its full width, assume Newtonian behavior and a viscosity of 30 Pa-s. Calculate the minimum clamping force necessary to hold the mold together if the injection takes place in 0.2 seconds. Assume the parting plane is oriented such that the projected area is given by the product's length times its width. 17.01 kN 16.2 kN 20 kN 8.55 kN
