What Defects a Vision Inspection Machine Can Actually Detect
The scope rule is simple: appearance defects. Here is what that covers in practice.
Our machines detect appearance defects. The working rule is that anything which can be seen by eye can be inspected by the vision system. That is a real boundary, not a slogan: it excludes internal material properties, and it includes anything visible on the surface.
On plastic packaging, the normal production defects are black spot, short mould, appearance damage, deformation, colour difference and stains. On caps and closures specifically the list extends to threads, compression rings, broken rings, notches, burrs, flashing, dimensional deviation, double gaskets, reverse gaskets, inner plugs and mould numbers.
On printed labels the defect vocabulary changes: oil splashing, label missing, label crooked and misprinting. On PET preforms it is black spot, crack, thread, flash, short shot, injection gate faults and deformation.
The number of defect types one machine can detect is not fixed. It depends on what you ask for, because each defect type has an inspection area and a tolerance, and those together decide how many cameras are needed and where they sit. That is why a defect list with physical samples is the first thing we ask for.
