- 5. How to distinguish between a cold slug vs. glass • Glass is characterized as a smooth to slightly grainy, cloudy blemish on the surface of the part • Blemishes of glass are found on nearly every part and is not considered a defect Shown here is a glass blemish on the surface of the part. This smooth, cloudy, glass blemish could even be located near the cold slug well. This is still an acceptable part.
- 6. Don’t be quick to judge • This “drool” is located around the cold slug well area in almost every part. It is something to be cautious about, but does not always yield a rejected part. • It is very rough when running a finger across and can also be characterized as a stringy glob • If this is seen anywhere on the inside of the part what should you do? – Flip the part over to the exterior side and look for any defect on the direct opposite side of the “drool” – If there is another defect on the direct opposite, then this is rejected – If there is nothing on the direct opposite side then this is acceptable
- 7. • Cold slugs usually have a rough feeling when you run your finger across it. • Rough does not always mean it is a cold slug, and smooth does not always mean it is not a cold slug. • To determine if a part is rejected due to a cold slug, the defect must be shown in the same spot on both sides of the part How to distinguish between a cold slug vs. glass There is a defect on the exterior of the part There is a defect on the direct opposite side in the interior of the part
