@kporter.stuff: Why Swapping Injection Molding Materials Late Can Warp Your Whole Part (Shrink Rate Mistake) A material substitution that looked harmless quietly broke our tooling assumptions. Shrink rate isn’t a footnote, it’s baked into the tool. Here’s what happens when a resin swap skips that check, and the process fix that prevents it. 🙌🏼⚙️
Can you recommend some programs or conventions to get better at mechanical/manufacturing engineering?

I did a material swap to eliminate need for cosmetic aluminum flake. Turned out that flake was better for friction, too, not just cosmetics. Started failing a bunch of test we previously passed with ease. We ended up paying to add it back 🤦♂️

I could list so many "procurement" changes that were a disaster.
