Cap inspection system for milk bottle manufacturer

High financial penalties imposed by supermarket chains when goods are faulty make it paramount that defects are kept to an absolute minimum.  ALS Controls faced a production line running 24 hours a day, 7 days a week manufacturing plastic milk bottles and injection moulded bottle caps. The 40mm diameter moulded caps are produced in three different colours to signify the type of milk; skimmed, semi-skimmed or full-cream.  It is important each cap is produced to the correct dimension and shape.
