100% Gel classification. (Extrusion).


Two recently upgraded on-line video inspection systems for cast and blown film take on-line inspection beyond its traditional role of spotting catastrophic quality problems. Introduced last month at the NPE NPE NullPointerException (Java)

NPE National Plastics Exposition

 show, these systems focus on tiny gels to help identify processing problems early on.

 gels by type. The software "memorizes" images of gels in order to classify them by source: carbon, crosslinking, unmelt, or contamination. This advanced gel classification has been put to use on 10 film production lines and five lab lines over the past year. The Eagle Gel Counter was shown at NPE on a Killion laboratory cast film line (see photo) from Davis-Standard Corp., Pawcatuck Pawcatuck is a census-designated place (CDP) in New London County, Connecticut, United States.

, Conn. Gel classification in the lab helps a processor identify quickly whether gels are coming from the original resin resin, any of a class of amorphous solids or semisolids. Resins are found in nature and are chiefly of vegetable origin. They are typically light yellow to dark brown in color; tasteless; odorless or faintly aromatic; translucent or transparent; brittle, fracturing  or are being caused by processing problems.

The second newly upgraded camera inspection system also classifies gels by type and size, but with a different approach. Nanosystems, LLC (Logical Link Control) See "LANs" under data link protocol.

 of Gainesville, Ga., classifies gels not by recognizing "learned" images but by using a lightness/darkness scale. Its Nanoman system differentiates gels as bright, bright with dark spots, or dark--which correspond to a gel, gel with speck, or speck. Nanoman then counts them and classifies them by size. This system can be confused by holes, which may appear bright or dark depending on how the system is lit. Nanosystems has about 80 installations globally. Tel: (770) 297-8188, www.nanosystems.com
