My company is new to injection molded components. Our first experience with a well known "rapid injection molding" company has not been very positive. The parts we received were not made to print, nor are they willing to take the parts back and work with our current mold. They insist on machining a whole new mold on each (slight) revision of our part (to be able to meet print specifications). Further, they insist that the molding process is simply trial and error at this point and they have no idea how many revisions it would take to make our part per the original print
Obviously, we are not happy with this. My question is, is this normal with injection molded parts? I would have thought that by paying for the mold and its associated costs, that we were guaranteeing that the parts would be made to print. I would like to quit working with this company, as I believe their business practices are less than proffessional. Are we going to encounter this with other molding companies? Any reccomendations on a good molder? The part we are doing is fairly simple, although the tolerances are fairly tight (+-.003 in places). Material is 30% carbon fiber composite.
