Auxiliaries at NPE: New Solutions from Material Preparation To Post-Mold Operations
There will be an extraordinary range of new auxiliary equipment on display at the show.
Testing & Measuring Instruments: More Versatile, Compact, Affordable
From polymer characterization to on-line bottle or preform inspection, coordinate measuring, and color sensing, new testing and measuring instruments at the NPE show in Chicago were easier to use and more compact, yet often packed higher performance than earlier versions—and sometimes with a more attractive price tag.
Ergonomically Designed Portable Color Spectrophotometer
A new color reflectance measurement instrument is ergonomically designed for use on the plant floor or outdoors.
How to Measure PET Pellets
PET(E)-extruded pellets are created from Polyethylene Terephthalate, a form of thermoplastic polyester resin derived from the combination of ethylene glycol and either purified terephthalic acid or dimethyl terephthalate.
Recyclers ... Is The Correct Color Important To You?
How to Measure: Plastic Preforms
• Preform color measurements can be used to verify lot-to-lot consistency, predict final blown bottle color from the preform color and get into target range when switching over a line to a new color. • Spectral measurements in the 360 - 390nm range on an UltraScan PRO and UltraScan VIS can be used to verify the presence of a UV absorber for food grade bottle cut-outs (can also be done on preforms with caution). • Haze measurements of bottle cut-outs are used to verify that internal scattering is minimal from lot-to-lot. • Color measurements of bottle cut-outs are used to verify lot-to-lot consistency and conformance to specification.
NPE 2006 News Wrap-Up: Testing and QC--New Lab Instruments Stress Affordability and Convenience
