This testing machine is suitable for testing the dynamic impact resistance of basketballs, footballs, volleyballs and handballs. It uses two high-speed rotating drums facing each other. Under the action of friction and compression, the test piece is thrown out at high speed and impacts the rebound board. The rebound board rebounds the test piece into the receiving funnel. Under the action of gravity, it is transmitted to the throwing drum and thrown out again. After a set number of tests, check the pressure change inside the sample, as well as whether it is cracked, burst, peeled, delaminated, broken, deformed, etc.
Equipment Features
1. Equipped with an advanced PLC programmable controller as the electrical control system. Utilizes a high-definition large color touch screen for controlling working status, data collection, operation processing, etc. It also has a data printing and storage function.
2. The number of detection times can be set. After the detection is completed, the equipment will automatically shut down and issue an alarm prompt.
3. It has the functions of power-off memory and automatic shutdown upon detecting a power break. In case of a sudden power outage, when power is restored, the equipment can automatically save data and continue operation based on the parameters set before the power break, without the need for manual startup and parameter setting.
4. Shutdown methods: automatic shutdown upon reaching the set number of tests, automatic shutdown and alarm upon detecting design damage or excessive deformation.
5. The equipment is equipped with a self-diagnosis system. In case of a malfunction, it will automatically diagnose and display the fault code, facilitating inspection and troubleshooting.

Core functions
Multi-scenario Impact Testing
1. Dynamic Impact Simulation:
✦ Impact energy: 0 - 5000J (accuracy ±0.5% FS), impact frequency: 1 - 50Hz (sine wave/random wave), simulating dribbling (impact force ≥ 2000N) and slam dunking (equivalent height of 3m free fall) by athletes.
✦ Detecting surface cracking of the basketball, air tightness of the inner bladder (pressure drop ≤ 10% within 24 hours), and the risk of delamination in the middle layer.
2. Fatigue Life Testing:
✦ Cycle impact times: 10⁴ - 10⁶ times, generating S-N fatigue curves, evaluating the performance degradation of the basketball over long-term use (a rebound rate drop of ≤5% is considered excellent).
Environmental Coupling Testing (Optional)
✦ Temperature and humidity cycling: temperature range -20°C to +60°C, humidity 10% to 95% RH, verifying the thermal aging and low-temperature brittleness of PU/rubber materials.
✦ Salt spray/dust simulation: simulating outdoor harsh environments according to ASTM B117 standards (salt spray deposition rate 1 - 3mL/80cm²/h), testing the anti-corrosion performance of the surface coating.
Intelligent Monitoring and Diagnosis:
Real-time multi-parameter collection:
✦ Peak impact force (±0.5% FS), rebound height (laser distance measurement ±0.1mm), pressure change (±0.1kPa), vibration spectrum (5 - 5000Hz).
✦ High-speed camera (10,000fps) captures the deformation of the basketball at the moment of impact, 3D digital image correlation (DIC) generates stress distribution cloud maps.
✦ AI failure warning: machine learning algorithms analyze abnormal impact waveforms, predict the risk of surface delamination or inner bladder leakage, automatically stop the machine and generate maintenance suggestions.
✦ Data traceability: one-click export of PDF/Excel reports (including impact energy-deformation curves, fatigue life prediction), supporting MES system integration and production batch traceability.
Technical highlights
1. High-precision impact drive:
✦ Servo hydraulic closed-loop control, dynamic response ≤ 5ms, waveform distortion rate < ±1%, supporting both free fall and guided impact modes.
✦ Modular impact head design (hemispherical/wedge-shaped), suitable for different test scenarios (such as side impact, vertical impact).
2. Bionic mechanics simulation: Six-axis robotic arm programming, reproducing real game shooting angles (30° to 70°) and ground rebound trajectories, making tests more realistic.
3. Safety and energy-saving design:
✦ Fully enclosed explosion-proof cabin (pressure resistance ≥ 15MPa), dual emergency stop protection, vibration isolation base, meeting ISO 13849 (PLe level) safety standards.
✦ Energy feedback technology saves energy by ≥ 30%, standby power consumption < 100W, noise < 65dB.
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, R&D cycle shortened by 50%, and defective product interception rate ≥ 99%.
4. Standard Compliance: Built-in 30+ test programs including FIBA, NBA, ASTM, etc., and one-click generation of global certification reports.
Application scenarios and industry value
Production quality inspection: Full inspection of basketballs for impact resistance before leaving the factory to screen out products with surface defects or poor inner bladder air tightness.
Research and development innovation:
- Optimize the impact resistance improvement effect of midsole density and PU surface thickness during foaming.
- Compare competitive product data (such as Spalding vs Wilson rebound consistency).
Event certification: FIBA official game ball certification, NBA game ball admission testing.
After-sales analysis: Process reproduction and improvement for user complaints such as glue separation and air leakage.
The spherical roundness testing machine, through 3D laser scanning and intelligent data analysis, upgrades the control of the geometric accuracy of the ball from "empirical spot checks" to "scientific full inspection", helping enterprises overcome the problem of product consistency. Whether it is to meet the strict competition standards of FIFA Pro or to endow mass-produced balls with ultimate symmetry, this equipment can serve as a core tool for production and research and development, safeguarding the competitive fairness of sports equipment and the brand's competitiveness.
