Drop Weight Testers up to 230 Joules

Developed in close collaboration with our customers. This allows the HIT230F drop weight tester to satisfy all relevant requirements from the fields of research & development and quality assurance. The HIT230F is available in two versions:

  • HIT230F drop weight tester for plastics
  • HIT230F drop weight tester – pre-damaging fiber composites for CAI tests

 It is not possible to combine the two tests.

Key Advantages and Features

Plastics

HIT230F drop weight tester for plastics

The HIT230F drop weight tester is ideally equipped for performing multiaxial impact tests on plastics. The range of application includes material characterization of standard specimens in accordance with established research and development and quality assurance standards.

Advantages of the drop weight tester for plastics testing

  • Tests possible over a wide temperature range without installing an expensive temperature chamber in the test frame.
  • The innovative design of the entire force measurement chain leads to a low noise measurement data. This allows a reliable determination of the materials characteristics to be achieved from the force deformation curve.
  • Safety device plus operator-friendly specimen clamping for high specimen throughput.
  • High measured-value acquisition-rate (4 MHz) combined with high (16-bit) resolution.

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.
