Colour durability control of plastic sheets

Colour durability control of plastic sheets at Rochling

Many years' experience in the machine vision field allows us to implement projects of large-scale colour durability control of products.

Our machines are important helpers in cases where it is necessary to maintain an identical colour in the entire product production batch, whether production takes minutes or days.

It was no different at Rochling. The turnkey PlasticSheets Opti control system was deployed for continuous control of extruded plastic sheets. The machine meets the strict quality requirements in the accuracy of colour deviation measurement within one production batch (ΔE <0.8). By deploying our solution, the company has completely eliminated complaints and the costs associated with them. Who wants to build a swimming pool to find out that one plastic sheet has a slightly different shade in the sun? Fortunately, these situations no longer occur thanks to our solution.
