Even the smallest faults in PET preforms have a signicant impact in bottle production and bottle quality. In the most severe cases, faulty preforms can even lead to malfunctions in the blowmoulder. With ever increasing outputs in the blow moulding systems, perfect preforms are indispensable. This is where preform in- spection systems come in: preform inspection systems check the preform’s quality and reject faulty preforms immediately from the produc- tion line. Thus preform inspection becomes an essential part of process quality control.
