Drop Hammer Test Equipment Offering Durable Construction and Performance for Continuous in Material Testing Laboratories
Product Description
The Falling Weight Impact Tester is specifically engineered for impact performance testing of plastic pipes, sheet metals, and related products. Its core purpose is to accurately evaluate the impact resistance properties of these materials, providing critical data for quality control and material qualification.
The control system incorporates advanced digital control technology, enabling precise parameter setting, automatic zero calibration, and automated hammer lifting and release. This intelligent design not only streamlines operational workflows but also effectively eliminates secondary impacts--ensuring consistent test conditions and reliable, repeatable results.
Instrument Features
Three-Level Safety Protection System
The tester is equipped with a multi-layer interlock protection mechanism to ensure operational safety:
- 1st Level: Sample Door Interlock Protection
- 2nd Level: Observation Window Interlock Protection
- 3rd Level: Upper & Lower Limit Position Protection
High-Speed Lifting Performance
Powered by a high-torque stepping motor, the tester achieves a lifting speed of up to 250 mm/sec--enabling the hammer to reach 2 meters from 0 in just 8 seconds. This significantly shortens test cycles and improves efficiency for high-throughput testing scenarios.
Intelligent Hover Function
Incorporates a multi-stage speed control algorithm to ensure smooth hammer deceleration and precise positioning with zero deviation. The advanced control logic eliminates inertial displacement, guaranteeing consistent test conditions and reliable data repeatability.
3D-Modeled Drop Hammer Guide Pipe
The drop hammer guide pipe is optimized via 3D modeling, integrating exhaust holes to minimize wind resistance during hammer descent--ensuring stable impact force transmission. Additionally, a hoop reinforcement structure is added to prevent structural failure and deformation, enhancing long-term operational reliability in rigorous testing environments.
Pneumatic Hammer Lifting & Release Mechanism
Abandoning traditional electromagnetic hammer mechanisms, the tester adopts a high-force pneumatic configuration for superior performance:
- Equipped with a 300N long-stroke dual air cylinder for powerful, consistent operation
- Features a rubber tendon plate hammer surface to ensure stable, non-damaging impact on specimens
- Pneumatic lifting/release design fundamentally eliminates issues such as cable bending, wire breakage, and electrical leakage common in electromagnetic systems
- Integrates a pneumatic automatic locking system, delivering enhanced safety and operational reliability
Integrated & Modular Assembly Design
- Mechanical Structure: Utilizes standardized aluminum alloy profile assembly, achieving process standardization, modular installation, and a lightweight yet high-strength design
- Electrical System: Configured with a 7-inch touchscreen and Delta PLC, ensuring intuitive operation, stable performance, and convenient maintenance

Main functions
The Dropping Hammer Impact Tester serves as a widely recognized precision testing instrument specifically engineered for evaluating the external impact strength of plastic pipes, plastic sheets, and non-metallic materials. It is a critical tool for performance assessment, quality control, and material qualification in the plastics, construction, and manufacturing industries.
For plastic pipes, the tester provides comprehensive impact testing coverage for a diverse range of products, including but not limited to: PVC-U water supply pipes, low-pressure water supply pipes, core-layer foam 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.
Principle
For batch or continuous extrusion production processes, the tester enables the determination of the product's True Impact Rate (TIR) by impacting the specified area of test specimens with a drop hammer of predefined mass and dimensions from a designated height.
This test method offers exceptional flexibility to meet the technical requirements of diverse products--achieved by adjusting the drop hammer mass, impact height, or both parameters.
Per standard testing protocols, the maximum allowable TIR value is specified as 10%.
