Sample-PreWatcher®
– for the Inspection of Preforms
The Sample-PreWatcher® continuously analyses the quality of preforms by
sampling individual preform batches.
The Sample-PreWatcher® performs a comprehensive measurement and inspection of preforms providing detailed objective quality data on the screen,
in reports or as database entries. The system helps to prevent recurring
production errors and delivers valuable data which allows for in-depth long
and short term quality analysis. Complete test results of a 96 cavity mold
are already provided within approximately 8 minutes allowing for startup
of a newly installed mold in a much shorter amount of time than previously
permitted. As the preforms do not come in contact with a person they don’t
have to be disposed of afterwards.
Inspection criteria geometry/body
Inspection criteria weight
\\ Length, diameter, shape, wall thickness, short-shots
\\ Length of gate
\\ Unmelted material
\\ Bubbles, oil splashes, burn spot, contamination
\\ High-precision weight measurement
Inspection criteria top sealing surface
\\ Defects in the sealing surface
\\ Scratches and notches in the area of
the seal
\\ Diameter, ovality
\\ Flashes
\\ High-precision measurement
Inspection criteria thread
\\ Contamination
\\ Thread measurement
\\ Flashes
The pocket wheel ensures a precise
and stable handling of the preforms
Inspection criteria color
\\ Color and intensity deviations
\\ Color differences L-a-b
\\ UV-measurement (presence of UV
blocker)
\\ IR-measurement (presence of barrier material)
Inspection criteria cavity number
reading
\\ Cavity related statistics
\\ Sorts preforms according to previously specified cavity numbers
Inspection criteria gate
With help of the rotating vacuum
plate a roll out image of the complete circumference is created
\\ Grooves, holes
\\ Contamination in the gate area
With the suction plate each preform is
rotated in front of the camera
