Rubber & Plastic Testing Machine

Precision Elasticity Measurement for Rubber Compounds

The SUNRISE SR-809 quantifies energy restitution in rubber materials through pendulum impact testing (0.5J), calculating rebound resilience as a percentage for quality control and aging studies per ISO 4662 and DIN 3512.

H2: Key Features

✔ Direct Readout: Auto-calculates rebound % (1% resolution)
✔ Wide Compatibility: Tests 30-85 IRHD rubber & cellular materials
✔ Safety Focus: Emergency stop + mechanical locks
✔ Certification Ready: Pre-loaded ISO, DIN, and GB test protocols

H3: Technical Specifications

H2: Compliance & Applications

Standards:

• ISO 4662:2017 (Vulcanized rubber rebound)
• DIN 3512:2020 (Schob pendulum method)
• GB/T 1681-2009 (China rubber elasticity)

Use Cases:

• Tire tread compound optimization
• Anti-vibration pad elasticity validation
• Aged rubber performance degradation

H3: Testing Workflow

1. Mount sample on anvil (adjust thickness to ≤60mm)
2. Release pendulum: 0.5J impact from 1.4-2.04m/s
3. Record: Rebound height ratio = (rebound height ÷ drop height) ×100%
4. Analyze: Compare pre/post-aging resilience %
