The core business of Lankhorst Mouldings Sneek (The Netherlands) is the development and production of large and/or complex plastic parts with high wall thickness. On their behalf, BPO has optimised a steel reinforced plastic rollstop system.

Detailled FEM analyses were used to optimise Lakhorst’s new rollstop system. These rollstops are used to store steel coils with a diameter ranging from ?680 to ?2500 [mm] up to 3 meters high.

The load produced by these coils is enormous: The maximum compression stress exerted on 4 coils is equal to 100 tons. Both the rail parts, with their moulded in steel bars, as well as the rollstops themselves were analysed for their long term stability and durability. De connection between two rail parts is analysed as well. That subsystem is as reliable as every other.

De optimisation performed by BPO has resulted in a durable, flexible, efficient and easily useable system that can be installed without additional tools and on top of that has a extreme long life span. It shows that even for extreme performances a solution in plastic can be found.
