Specializing in the development of ball rebound height testing machines, strictly adhering to international and domestic standards such as ISO 20927 and GB/T 22868, this equipment is suitable for the rebound performance testing of all types of sports balls, including footballs, basketballs, and tennis balls. The device is equipped with high-precision laser displacement sensors and an intelligent data acquisition system, accurately measuring the rebound height of the ball after it freely falls from a specified height (standard test height of 2000mm) onto a rigid surface. The detection accuracy reaches ±1mm, and it automatically calculates core indicators such as the rebound rate and energy loss rate. It supports custom test modes, allowing for the adjustment of the drop height (500 - 3000mm) and environmental temperature and humidity (temperature 10 - 50℃, humidity 20 - 90% RH) to simulate rebound performance under different usage scenarios. For balls of different materials (PU, rubber, and fur) and structures, it is equipped with dedicated buffer fixtures and calibration programs to ensure a damage-free testing process and accurate data. It is applicable for quality inspection of finished products in ball manufacturing enterprises, new product development (optimizing the ratio of inner bladder and outer skin materials), and certification by third-party testing institutions.
Product Overview
This machine is suitable for testing basketballs, footballs, volleyballs, handballs, tennis balls, pickleballs, etc. Simply place the ball under the fixture and it will rise to a certain height, then drop the ball and measure its rebound height.

Core Functions
Precise Bounce Height Testing
✦ Free Fall Simulation: Drop height 300 - 2000mm (adjustable, accuracy ±0.1mm), bounce height measurement range 0 - 1500mm (laser distance measurement accuracy ±0.1mm), calculate rebound rate (≥80% is qualified for competition level).
✦ Multi-ball Continuous Testing: Automatic feeding system (capacity ≥ 50 balls), testing speed 10 - 60 balls/minute, screen for consistency of rebound in the same batch (deviation ≤ ±2%).
Environmental Coupling Testing (Optional)
✦ Temperature and Humidity Cycle Testing: Temperature range -20℃ to +60℃ (accuracy ±0.5℃), humidity 10% to 95% RH, verify the elastic attenuation of ball materials (such as rubber, PU) under extreme conditions (rebound rate change ≤ 3%).
✦ Dynamic Fatigue Testing: Cycle impact times 10⁴ to 10⁶ times (frequency 1 - 30Hz), detect the attenuation of rebound performance after long-term use (S-N curve generation).
Intelligent Data Analysis
Real-time collection of all parameters:
✦ Bounce height (±0.1mm), impact force (±0.5% FS), ball deformation (high-speed camera 1000fps), air pressure (±0.1kPa).
Generate rebound trajectory heat map with D motion trajectory analysis software, locate eccentric or material uneven areas.
✦ Automatic Sorting and Reporting: One-click generation of PDF/Excel reports (including rebound rate distribution, standard deviation statistics), support MES system integration and production batch traceability.
Technical Highlights
1. High Efficiency and Precision: A single test cycle is ≤ 3 seconds, with data repeatability error < ±0.2%. Supports dual-station parallel testing (efficiency increased by 300%).
2. Cost Optimization: Replaces manual spot checks, improving quality inspection efficiency by 15 times and reducing defective product rate by 95%.
3. Standard Compliance: Built-in 20+ test programs including FIBA, ITF, GB, etc. One-click generation of multi-language certification reports (Chinese/English/Japanese/European standards).
4. Flexible Adaptability
✦ Compatible with ball diameters of 60~250mm (can be extended to beach balls/medical balls), and impact energy of 0~200J (can be optionally extended to 500J).
✦ Optional surface friction coefficient test (0.1~1.0μ), and dynamic balance detection (eccentricity ≤ 0.1g·cm).
Equipment Advantages
1. High Efficiency and Precision: The single impact test cycle is ≤ 20 seconds, with data repeatability error < ±0.5%. It supports four-position parallel testing (efficiency increased by 400%).
2. Flexible Adaptability:
✦ Compatible with basketball sizes 6 to 7 (diameter 238 to 242mm), and impact energy 0 to 10 kJ (expandable).
✦ Optional dynamic balance testing (eccentricity ≤ 1g·cm) and surface friction coefficient detection (0.2 to 0.6μ).
3. Cost Optimization: Laboratory replacement of player actual testing, reducing the R&D cycle by 50%, and the defective product interception rate ≥ 99%.
4. Standard Compliance: Built-in 30+ test procedures including FIBA, NBA, ASTM, etc., and can generate global certification reports with one click.
Application scenarios and industry value
Production quality inspection: 100% rebound performance screening of balls before leaving the factory to ensure that products of the same batch meet the competition standards (such as FIBA basketball rebound rate ≥ 80%).
Material research and development:
- Optimize the influence of rubber formula and midsole structure on rebound performance.
- Compare competitive product data (such as Wilson tennis vs Dunlop rebound consistency).
Event certification: FIBA official ball certification, ITF professional tennis access test.
Training assistance: Professional teams select training balls to ensure the stability of bounce.
The ball rebound height testing machine, through high-precision dynamic simulation and intelligent data analysis, upgrades the quality control of balls from "empirical judgment" to "scientific quantification", helping enterprises overcome the problem of product consistency. Whether it is to create high-performance balls for top-level events or to optimize material processes for mass-produced products, this equipment can serve as a core tool for research and development and production, safeguarding the competitive performance and market competitiveness of sports equipment.
