Maintaining tight tolerances and QC costs far more than you think. I work in the aerospace industry where we pay hundreds, even thousands of dollars for things like nuts and screws that are almost identical to those found at Home Depot for pennies. The difference is the tight tolerances they have to adhere to, inspections loops, and other QC measures. Quality costs buku bucks.
Maybe, but you pay hundreds and thousands of dollars, sometimes just because you will. Just because you are part of an industry and pay more, doesnt mean it costs any more to manufacture.
Sort of like how the military pays 10's of thousands of dollars for office furniture that we would buy for hundreds. I work for Family Dollar and many of our products cost penny's and we set a quality expectation and test for it. We fight the perception that Dollar channel stores sell old, inferior, or late model goods. We are very sensitive to goods matching the quality that we set.
I worked for a tool company, we had extreme tolerances on tap's and dies. Each one was almost exactly alike. They all sat in a bin. We would lazer etch Matco, Mac, Snap-on (sub-brands) -> blue point, cornwell, Irwin, Greenlee.
A set of Irwin might sell for $250, Snap-on $475 and the parts came off the same machine from the same run, from the same stock steel rods (sourced from China) Even with the same lifetime guarantee, people were willing to pay 2x for Snap-on.
In industries like aerospace and pharmeceutical, people pay more because the consumers pay more. Penny pinching "can lead" to inferior parts and performance. It isn't worth investigating in many cases. Just because something is "quality." doesnt mean it was produced more expensively.
Another example would be hand written weights on discs. A simple inline scale with a printed wt gives better accuracy and quality look AND reduces the labor to hand weigh and write the weight. In that case better quality would be cheaper. Selection of appropriate machinery and processes should reduce costs as it reduces scrap, increases production efficiencies and reduces labor.
