A key aspect of the characterization of molding materials is the inter-laboratory reproducibility of test results.
The objectives of testing specimens taken from finished parts or intermediate products differ significantly from those of molding materials testing.
Molding materials testing produces material data that can be compared. This data can be used to compare materials, however calculating the characteristics of a finished product is not possible in most cases.
Testing components often places particular demands on a drop weight tester. The impact surface of the component is often not at an exact right angle to the direction of impact, which means the guides must be massive; some components must even be fixed in special grips.
Two steel columns provide highly accurate guidance for ProLine’s moving crosshead. The stiff load-frame profile and generous connecting surfaces reduce the inclination angle of the crosshead under load, enabling very precise alignment and application of force to the specimen.
