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%.
