Top-10 Injection Molding Defects And How To Fix Them

Causes: Flow line defects are caused by the varying speed at which the molten plastic flows as it changes direction through the contours and bends inside the mold tool. They also occur when the plastic flows through sections with varying wall thickness, or when the injection speed is too low causing the plastic to solidify at different speeds.

Sand Casting | Metal Casting Resources

What is PPM and How do I calculate it?

Definition: One PPM means one (defect or event) in a million or 1/1,000,000. There was a time when you were considered a pretty good supplier when your defect rate was less than 1%, (10,000 PPM), then the expectation was increased to 0.1% or 1,000 PPM. Now the rate for most automotive components is targeted at 25 PPM or 0.0025%
