You send one drawing to three shops and get $150, $260, and $400 quotes for the same part. Under deadline, that inconsistency blocks approvals and
A “hard-anodized” part that cracks under torque isn’t a design flaw—it’s a control problem. When aluminum loses strength after anodizing, it usually means the process
Your threads fit before anodizing — but seize once parts come back from coating. The supplier blames “design tolerance,” you lose days re-tapping or scrapping
You send out your deep-pocket drawing and get silence—or a quote three times higher than expected. It’s rarely your design at fault. Most shops avoid
Quotes come back slow or overpriced. Some shops decline. Others say your tolerances look “too tight.” You start wondering—are you paying for precision that doesn’t
You expected grinding to make your helical gears run quiet — yet they still whine under load. It’s rarely a design flaw. Most often, the
Your drawing looks simple, but every quote drags. The real slowdown often isn’t workload — it’s your default tolerances. Many shops see ±0.01 mm callouts
