Impact Tester

A: It is a mechanical testing device that applies a sudden, controlled impact force to a test piece to measure its impact resistance (ability to withstand sudden loads) and determine parameters like impact strength or toughness.

A: The test setup consists of a drop tower, a weight or impactor, and a specimen holder. The weight is dropped from a predetermined height onto the specimen, and sensors record the force, velocity, and energy during impact.

A: Use a standard weight or calibration block (with known impact energy) to verify the machine’s energy reading. For pendulum models, check the pendulum’s swing accuracy and friction loss.

A: Yes. For non-metallic materials: Use low-impact-energy pendulums (e.g., 0–50 J) to avoid overloading fragile materials. Choose appropriate notch types (e.g., V-notch for rigid plastics, U-notch for brittle ceramics). For flexible materials (e.g., rubber), use a tensile impact tester (a variant) to measure impact resistance under stretching.

A: Daily: Clean the test area (remove test piece fragments) and check if the pendulum/hammer is loose;
Monthly: Lubricate the pendulum pivot (use high-temperature-resistant grease for models with temperature chambers) and inspect the clamping device for wear;
Annually: Calibrate the energy sensor, check the safety shield for cracks, and replace worn parts (e.g., clamping jaws).

A: With regular maintenance:
Main body (frame, pendulum): 10–15 years (high-strength steel structures are durable).
Energy sensor/clamping parts: 5–8 years (replaceable if worn).
Temperature control system (for low/high-temperature models): 3–6 years (cooling compressors may need replacement).
