Drop Hammer Test Equipment for Real World Impact Simulation
Professional testing equipment engineered to simulate real-world impact conditions for product development and safety testing applications.
Product Overview
Compliant with round-the-clock testing methods for external blow resistance of thermoplastics pipes, this professional tester is extensively adopted to assess the external impact strength of plastic pipes, plastic plates, and diverse non-metallic materials.
For plastic pipe testing scenarios, the equipment supports a full range of pipe types including PVC-U water supply pipes, low-pressure water supply pipes, core-layer foamed pipes, double-wall corrugated pipes, carat pipes, steel belt reinforced pipes, PE water supply pipes, MPP power pipes, hollow wall winding pipes, and CPVC power pipes, covering mainstream plastic pipeline specifications for industrial and construction applications.
Instrument Features
- Three-tier Safety Protection Design: Hierarchical safety protection system with primary sample access door, secondary observation window door, and tertiary upper/lower stroke limit protection structures
- High-speed Lifting Performance: High-torque stepping motor delivers rapid lifting speed of 250 mm per second, completing full 2-meter stroke in just 8 seconds
- Smart Position Hovering Function: Multi-stage speed regulation programming enables stable hovering and accurate positioning of drop hammer
- Optimized Exhaust Pipe Structure: 3D-modeled drop hammer guide pipe with optimized exhaust openings minimizes air resistance, reinforced circumferential hoop structures prevent deformation

Testing Definitions
True Impact Rate (TIR):
When testing an entire product batch, the true impact rate refers to the quotient obtained by dividing the quantity of impact-damaged specimens by the total number of impact tests, presented as a percentage.
Failure:
A specimen is defined as failed when visible cracks, fissures, or complete fracture can be identified by visual inspection after impact loading. Simple indentations or surface discoloration are not considered specimen failure.
Testing Principle
Mount the pipe or profile specimen onto the workbench and calibrate the sample elevation until its top surface aligns precisely with the lower boundary of the photoelectric sensing system. Select appropriate hammer tip and dead load according to test standards, then assemble the impact hammer assembly. Tune the position of the electromagnetic vibration damping system and suspend the hammer in position. During testing, the hammer undergoes free fall from the preconfigured height and strikes the specimen. Operators then examine whether cracks or fractures emerge on the tested pipe or profile after impact.
