Composite hard plate drop ball impact tester

In the field of pharmaceutical packaging, especially composite hard sheet materials such as aluminum-plastic blister packs (PTP aluminum foil) and tropical aluminum, their impact resistance is one of the key indicators for evaluating packaging reliability. These materials may face unexpected drops, collisions, or impacts during drug production, transportation, storage, and even patient access. If the toughness of the material is insufficient, it is highly likely to cause perforation and rupture of the packaging surface, leading to drug moisture, contamination, oxidation, and even leakage, directly endangering drug quality and patient medication safety. Therefore, conducting scientific and quantitative drop ball (dart) impact testing on composite hard sheets for drug packaging, simulating real risk scenarios and quantifying their resistance to damage, is a crucial step for pharmaceutical companies, drug packaging material manufacturers, and quality control departments in material selection, process optimization, and finished product release. It is essential for building a sound drug packaging safety system.

1、 The Scientific Principles and Quality Control Significance of Falling Ball Impact Testing
This test is based on the basic principle of the free fall dart method, where a precisely controlled heavy hammer (dart head) falls freely from a specified height to impact a horizontally clamped specimen. The core objective is to determine the impact energy required to cause 50% of the sample to break, and to characterize the impact toughness of the material using the observable physical quantity of "impact damage mass". Specifically, the test adopts the statistical "step method" or "limit method": by systematically adjusting the weight (or height) of the dart, a group of samples are impacted, and based on the results of whether the samples are damaged, the critical energy value corresponding to a 50% probability of damage is calculated and determined. This value can effectively distinguish the differences in toughness of packaging materials with different materials, thicknesses, and composite processes. For the pharmaceutical industry, the use ofComposite hard plate drop ball impact testerObtaining accurate data can achieve multiple quality control objectives: at the research and development end, provide performance comparison basis for new high barrier, easy to tear blister materials; On the procurement side, strict incoming inspection of packaging materials is carried out; At the production end, monitor the impact of production process stability (such as coating and composite processes) on the mechanical properties of finished products to ensure that the packaging used for each batch of drugs has reliable strength to withstand conventional impacts.

2、 Innovation of Instrument Core Technology and Analysis of Professional Performance
To accurately implement standard methods and improve testing efficiency and user experience, this instrument designed by Jinan Xio Electromechanical integrates multiple technologies and user-friendly design:

1. Dual method compatibility and intelligent operationThe instrument is compatible with the A method (applicable to general films and thin sheets) and B method (applicable to materials with high impact strength) specified in standards such as GB/T9639.1. Users can easily select testing methods, set parameters, and view testing progress and statistical results in real time through the 7-inch HMI touch screen, making the operation intuitive and simple.

2. High precision impact and clamping systemThe dart head adopts electromagnetic suction and automatic release device, avoiding the friction and shaking that may be caused by traditional mechanical release methods, ensuring consistent starting state of descent, and improving test repeatability. The sample clamping adopts pneumatic method to provide uniform and stable clamping force, ensuring that the sample is flat without sliding at the moment of impact, and the test results are more authentic and reliable.

3. Humanized detail designThe instrument provides two operation modes, manual and foot switch, to adapt to different experimental habits and improve continuous testing efficiency. Built in observation light can clearly illuminate the surface of the sample after impact, assisting the operator in accurately determining the damage status. Equipped with a standard micro printer, it can directly output test conditions, results, and statistical reports.

4. Key parameters and accuracyThe impact height of the instrument can reach 1500mm, providing sufficient potential energy range; The testing quality covers a wide range (A method 50-2000g, B method 300-2000g), and is equipped with standard diameter dart heads (A method Φ 38mm, B method Φ 50mm). The accuracy of quality (energy) testing is as high as 0.1g (0.1J), which can accurately capture subtle differences in material toughness.
