Inspection & Control

We offer various inspection & control stations in our packaging lines. Integrity, size and orientation of the handled products are inspected and controlled prior to packaging. Rejects are accumulated and, when applicable, can be fed back into the packaging line and rethreaded instantly.


The Weighpack Monoctopus inspection and packing system is designed for 100% fully automatic quality control and packing of bolts. Up to 4 cameras can be used to inspect the shape of the product. Geometrical measurement is performed in a continuous flow, therefore speeds up to 200 pieces per minute can be obtained. Visual inspection allows tolerances up to 0.05 mm depending on the camera used. The Monoctopus Bolt Inspection System is a high speed inspection machine, designed for 100% sorting and checking of ferrous parts with head. The inspection system is non sensitive to oil or dust.

The new Weighpack Monoctonut inspection and packing system is designed for 100% fully automatic quality control and packing of nuts, washers, stamping parts, etc. by using our new “part turn over system”. Visual inspection is performed on top and bottom side of the part by using 2 separate cameras directly onto the part without interference of any transport media like glass plates. Up to 4 camera’s can be used to inspect the complete shape of the part. Geometrical measurement is performed in a continuous flow process, allowing for very high handling speed. Visual inspection can be performed with a maximum tolerance of 0.05 mm, depending on camera and objective used.
