ZwickRoell has been delivering quality testing systems for impact testing for years. Based on their years of experience, ZwickRoell presented a new product line of drop weight testers under the Amsler brand in October at testXpo 2017 – the International Forum for Materials Testing. ZwickRoell rounds out its portfolio of impact testing for a wide range of applications with the following products.

Drop Weight Testers up to 2000 Joules

Key Advantages and Features of the Drop Weight Testers at a Glance

Materials testing in the plastics industry often involves instrumented multi-axial puncture tests as described in the international standard ISO 6603-2 and in ASTM D3763. While in Europe, the typical fall height is one meter, which means an impact velocity of 4.4 m/s, many international specifications in the automotive industry stipulate slower speeds of 2.2 m/s, which require relatively large drop weights, as well as higher speeds of 6.6 m/s, which require a greater fall height or acceleration of the drop weight tester. Additional test types, such as instrumented Charpy, Izod, or impact tensile tests are also useful in materials development.

Composites testing often involves pre-damaging prepared test plates. The compression test that follows is called a Compression After Impact (CAI) test and is described in many national and international standards.

When examining components, the mechanical characteristics of complete assemblies or systems are tested. Familiar examples include the testing of safety gear, such as helmets, protectors, or bullet-proof vests. Often, the engineer of a component wants to validate the design in its used condition. Drop weight testers are suitable for characterizing these properties using a wide range of deformation speeds and temperatures.

Specimen Preparation for Plastics

Good testing starts with a good specimen.

Testing solutions for the plastics industry
Standard thermoplastics and thermoset molding specimen are produced by injection or compression molding. Material characteristics are significantly influenced by production parameters such as pressure, temperature, and flow speed. Specimen are taken from slabs and components through mechanical processing such as per ISO 2818.
