Check your parts boys and girls

Quality costs money and most people aren't willing to pay a 50% premium for it. Some are. Processes that rely on human beings are fraught with uncertainty and mistakes will be made and get out the door. Even stuff that is made in US is just as susceptible. I've been in manufacturing my whole life and the folks that are doing low paid assembly work are not the rocket scientists you'd like them to be. There are exceptions, but most manufactures have trouble getting people to show up each day, and preferably sober. How many of those pumps would can be assembled before a person's mind goes numb and they don't care anymore? I don't trust anything I buy anymore whether is it Harbor Freight or made in USA.
A lot of truth. I have been in manufacturing also. Basically, there are 2 categories.
  1. Your product sells to the public
  2. You make a part that goes into the product sold to the public.
Our company makes components for product (number 2 above). Our tolerances are in microns, including run outs, parallels, perpendicularity, thickness, counterbores, grooves, I.D's, etc etc etc. We can send our customers 1,000,000 good parts, and if the millionth and one is out of spec, it's a huge deal. You are correct, work force is tough to find, and companies have to make safety and quality the lead driver, not production.
