Customised engineering example

Plastic sachets with welded seams are frequently used for measured applications of liquids, creams and gels. A quick quality test for their integrity involves compression either to burst, or to resist a defined compressive force. This may require containment for spillage, but also for alignment. Our client was testing pharmaceutical sachets.

Mecmesin designed a sliding container, engaging under the test compression plate with ball catches for exact axial placement. This enabled quick exchange of test samples for maximum throughput and repeatability.

Custom fixture design

This adjustable fixture can also be used for similar packaging in other industries, for example, condiment single-serve sachets.

Our VectorPro software environment is powerful, yet simple-to-use and the database architecture supports the stringent regulations of the medical and pharmaceutical industries—including test standards associated with medical device and sterile packaging.
