As with most authors, F&K agree that the total per-piece cost of injection molding, c [$/part], is the sum of three separate factors, namely, material cost, processing cost and molding cost respectively. Ability to digitally create a molding process with measurable targets before engineering the injection mold, establish measurable cycle times (fill, pack, cooling, pressures), determine warp, venting, part sizes and steel safe areas, and use pressure and temperature sensors, as well as other scientific molding information, and possess end of. The part color is the factor which designers and product engineers will neglect, as they assume piece pricing of all colors are the same. Mold itself is expensive - Need mass production to justify these costs. N = total number of parts n = number of parts molded in one shot t = cycle time Production Cost ($/part) = Material Cost +Mold Cost/N +Molding Machine Cost ($/hr)∗t/n 3. Part complexity Just as the number of cavities plays a role in determining the cost of the mold, so does part complexity. 4 Injection mechanism NOVADURAN can be molded by the basic injection machine which has the function of constant injection speed and two-stage injection pressure control, but when molding the product which severe measurement,.
