The falling ball rebound instrument is designed and manufactured according to GB/T6670-2008 or ISO8307 or ASMD3574. It is suitable for determining the falling ball rebound property of soft polyurethane foam. The instrument calculates the maximum rebound height of the steel ball and the percentage of the falling height of the steel ball by the steel ball with a given diameter and quality falling freely on the foam sample at a specified height, and the rebound rate represents the resilience of the foam.

FAQ

1. What is a Falling Ball Rebound Instrument used for?

It measures the impact resilience and rebound characteristics of materials by dropping a ball onto the surface and recording the rebound.

2. How does the instrument work?

A ball is released from a fixed height onto the test sample, and sensors record the rebound height or energy to calculate material properties.

3. What types of materials can be tested?

Commonly used for plastics, rubbers, coatings, and other materials requiring assessment of elasticity or surface hardness.

4. How is test data recorded and analyzed?

Data is captured digitally, displayed on a screen, and can be stored or exported for detailed analysis using the instrument software.

5. What maintenance is required for the instrument?

Regular cleaning, inspection of moving parts, calibration checks, software updates, and careful handling of balls and sensors are recommended to ensure accurate results.
