Drop Hammer Test Equipment Suitable for Testing Impact Absorption and Resistance Characteristics of Industrial Products
Product Description:
The Falling Weight Deflectometer Impact Tester for Plastic Pipes—designed in full compliance with ISO 4422, ISO 3127, and ASTM D2444 standards—is specifically engineered to assess the external impact resistance of thermoplastic pipes with circular cross-sections. In accordance with standardized test protocols, test specimens are subjected to impact from a falling striker (of predefined mass and geometric configuration) that is dropped from a known height onto designated positions along the specimen’s circumference.
Beyond individual specimen testing, the apparatus enables the statistical estimation of the true impact failure rate for an entire production batch or extruder production run, providing critical data for quality control, batch acceptance, and process optimization in plastic pipe manufacturing.
Product Structure:
Anti-Rebound Capture Mechanism
The tester is equipped with a dedicated anti-rebound device that achieves a 100% capture success rate, eliminating invalid secondary impacts for accurate test data. It integrates a premium-grade imported AC servo system, which delivers high-precision positioning and rapid lifting velocity to ensure efficient and repeatable test operations.
Flexible Impact Height Configuration
The impact height supports dual operational modes: user-defined manual setting (for customized test requirements) and automated precision calibration (for compliance with standardized testing protocols), catering to both routine and specialized impact testing needs.
Integrated Personnel Safety Protection System
The instrument is outfitted with a full set of automatic safety protection components, including a lockable specimen access door, shock-absorbing buffers, and impact-resistant safety windows. This system creates a secure testing environment and prevents operator exposure to potential hazards during impact procedures.
High-Precision Lifting Height Calibration
It features built-in automatic lifting height calibration with a calibration accuracy of ±2mm, ensuring consistent impact energy delivery and eliminating height deviation-induced test result errors.
Modular Impact Hammer Assembly
Adopting a combination-type impact hammer structure, the device enables flexible weight configuration by adding or removing hammer weights. This adaptability allows it to meet diverse impact energy requirements across different plastic pipe testing standards.
Adjustable Pneumatic Anti-Secondary Impact Mechanism
The pneumatic anti-secondary impact capture device supports on-demand adjustment of operating air pressure, which enhances the mechanism’s capture reliability and adaptability to varying test conditions and specimen types.
Dual-Screw Specimen Support Structure
Specimen positioning relies on a twin-screw support system, which delivers exceptional structural stability and high rigidity. This design ensures precise and fixed specimen placement throughout the impact process, avoiding positional shifts that could compromise test validity.
