drop testing machine for shock - pre - conditioned drop test

Drop Weight Impact Testing Machine During the products handling or transport process, there may be drop/ fall, which results in damage within the products. And the machine simulates the drop/ fall of a finished product to evaluate the damage. Standard test of packaged freights (surfaces,corners, and edges), etc. can be performed efficiently with a high accuracy.

FEATURES

1. Outside material: advanced paint coat.

2. It adopts double wings to fix the products well when testing.

3. Power system: drive device (imported motor + speed reducer +Axel+ upper and lower limitation + spring+electromagnet)+dropping device(dropping standard board +magnet + safety spacing push rod + automatic return back + digital alto-meter +encoder +hydraulic pressure buffering device)

4. Control system: adopting electromagnet sensor control, the interface is easy to operate, high degree automatic control.

5. Safety device: upper and lower limitation device, automatic off-power device if electricity leakage occurs.

SPECIFICATION

A Drop Testing Machine for Shock - Pre-Conditioned Drop Test is designed to simulate and evaluate the effects of shock and impact on various products, such as food packaging, electronics, or industrial goods, after they have been subjected to specific environmental conditions. The term "pre-conditioned" refers to subjecting the test sample to specific environmental conditions (such as temperature, humidity, or vibration) before performing the drop test to simulate real-world situations where products may encounter extreme environments before or during transportation, handling, or storage.

1. Environmental Conditioning Chamber:

• Before performing the drop test, the sample is conditioned in an environmental chamber that simulates various real-world environmental conditions. This chamber can be programmed to control temperature, humidity, vibration, or other factors that could affect the product.

• The pre-conditioning process can expose the product to extreme conditions like high heat, cold temperatures, high humidity, or freezing conditions to replicate the conditions the product may face in real-life scenarios (such as storage in a hot warehouse or a frozen shipping container).

2. Pre-Conditioning Process:

• Heat cycling (exposing the package or product to high temperatures followed by cooling).

• Humidity conditioning (simulating high humidity levels, which may affect the packaging material or product quality).

• Freeze-thaw cycling (exposing the product to freezing and thawing conditions).

• Vibration or shock exposure (simulating impacts during transport).

• The conditioning stage is designed to simulate the conditions the product will undergo during transportation, storage, or handling. This could include:

• The test sample stays in the environmental chamber for a specified period to ensure it reaches a steady-state condition before the drop test is performed.

3. Drop Test Mechanism:

• After the product is pre-conditioned, it is transferred to the drop testing machine where the pre-conditioned product will undergo a shock drop test.

• The machine simulates real-world impacts by dropping the sample from a specified height or force, ensuring the product is subjected to shock forces typically encountered during handling or transportation.

• The machine may feature an adjustable drop height, so the test can be tailored to simulate different types of shocks the product may experience during its journey.

4. Testing with Different Impact Surfaces:

• During the drop test, the product can be dropped onto different surfaces (hard surfaces like concrete, or softer surfaces like foam) to simulate various potential impact scenarios.

• The surface type can be adjusted depending on the product's intended usage environment (e.g., products may be dropped on hard concrete surfaces or softer surfaces like padded packaging).

5. Shock and Impact Simulation:

• The drop test aims to simulate the shock and impact forces the product experiences during real-life handling and transportation. The shock can affect not only the physical integrity of the packaging but also the functionality and performance of the product inside.

• In addition to simple free-fall drop tests, dynamic shock testing can be incorporated, where the impact is applied with a mechanical force or by accelerating the object before release to simulate more severe impacts.

6. Data Logging and Analysis:

• The machine often includes data logging and recording features to track key parameters, including the height of the drop, impact force, number of drops, and test conditions.

• Data collected during the pre-conditioning and drop tests can be analyzed to assess whether the product was damaged during impact. Analysis can include checking for cracks, deformation, leaks, or performance degradation.

7. Customizable Test Parameters:

• Drop height: To simulate drops from different heights, including low, medium, or high-risk environments.

• Test duration: To ensure the sample is exposed to the conditioning environment long enough to mimic real-world scenarios.

• Impact orientation: Products can be tested for impacts from different angles (e.g., corner, edge, or flat face).

• Multiple cycles: To simulate repeated drops or impacts, ensuring that the product's resilience is tested over time.

• The machine allows for the customization of key testing parameters, including:

8. Post-Test Evaluation:

• After the drop test, the product undergoes a detailed visual inspection to check for physical damage (e.g., cracks, punctures, deformation) and functional testing (e.g., checking if the packaging remains sealed or if the product inside has been compromised).

• In some cases, the machine can be connected to an additional testing system to perform performance assessments (for example, testing if the food packaging is still airtight after the shock).
