Plastic Component Tension Test
The customer manufactures rigid plastic links which, when assembled, form a conveyor.
Mecmesin provided a customised solution based around a 5000N capacity motorised test stand fitted with S-Beam load cells and a digital height scale for measuring crosshead movement. It provided the necessary repeatability of results by virtue of operating at a fixed speed of 50mm/min and using the high-speed peak-capture facility of the AFTI display to record the maximum tensile force as the plastic link suddenly snapped. A gripping fixture using the location holes of the link and quick-fitting holding pins was specially designed. The software DataPlot-X was configured to start taking data when a small pre-load of 10N was applied to the link (to take up any slack within the grip/link) and the test was conducted until the plastic link broke at forces in the region of 4000N.
