Versatile Drop Hammer Test Equipment for Various Industrial Applications
Product Description:
The Round-Robin Method/Tester for Determination of External Impact Resistance of Thermoplastics Pipes is a widely recognized precision testing solution specifically engineered for evaluating the external impact strength of thermoplastics pipes, plastic sheets, and non-metallic materials. It serves as a core instrument for material performance assessment and product quality verification in related industries.
For plastic pipes, the method/tester encompasses testing for a comprehensive 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, 克拉管 (Carat pipes), steel strip-reinforced pipes, PE water supply pipes, MPP power pipes, hollow wall winding pipes, and CPVC power pipes.
Instrument Features:
1. 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.
2. 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 operational efficiency for high-throughput testing scenarios.
3. 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.
4. 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.
5. 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.
6. 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 is a widely recognized precision testing instrument specifically engineered for evaluating the external impact strength of plastic pipes, plastic sheets, and non-metallic materials. It serves as a critical tool for material performance assessment and product quality compliance in the plastics, construction, and manufacturing industries.
For plastic pipes, the tester encompasses comprehensive performance testing 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.
Defination:
1. True Impact Rate (TIR)
The True Impact Rate (TIR) is defined as the percentage of impact-damaged specimens relative to the total number of tested specimens when an entire batch of products undergoes impact testing. Its calculation formula is:
TIR = (Total number of impact-damaged specimens / Total number of tested specimens) × 100%
2. Damage (Definition)
For the purpose of this test, damage is defined as the presence of cracks, crevices, or complete specimen breakage observed via visual inspection after impact. Mere indentations or discoloration on the specimen surface caused by the drop hammer impact shall not be deemed damage.
