What is important in good injection mold design?
A good design must be practical. The mold maker must be able to produce the components in a logical, orderly manner to make money. Often, close tolerance dimensions are specified when a much looser tolerance could have easily done the job. • Take an ejector pin plate, for example. Everyone knows that the thickness is basically irrelevant, but usually the dimension given is a close tolerance size. An experienced toolmaker will just ignore the tolerance and proceed, but nowadays, with the specialization of tasks in the shop, a less skilled operator would waste precious time holding an unreasonable tolerance. • The 3D geometry must be clean. The fast pace of mold making today makes it essential to have efficient, reliable software. The days of vague sketches, or toolmakers making up the design as they go are long gone. There are many excellent companies that offer high end software programs for designing molds, dies, and just about any kind of tooling you can imagine. CNC machines need cl
