Rubber & Plastic Testing Machine

Dynamic Fatigue Testing for Rubber Components

The SUNRISE SR-371 simulates real-world flexing conditions with 1.7Hz cyclic stretching and adjustable elongation ratios, measuring crack growth and fatigue life of rubber products per ASTM D4482 standards.

H2: Key Features

✔ High Throughput: Simultaneous testing of 24 dumbbell specimens
✔ Precision Control: Cam-driven mechanism ensures consistent 1.6-2.4x elongation
✔ Smart Data Management: Windows software for curve analysis & report generation
✔ OEM Ready: Pre-configured for ASTM D4482 compliance

H3: Technical Specifications

H2: Compliance & Applications

Standards:

• ASTM D4482-22 (Rubber fatigue testing)

Use Cases:

• Automotive vibration mounts durability
• Rubber hose bend cycle validation
• Industrial seal lifespan prediction

H3: Testing Workflow

1. Mount specimens in 24 stations (ASTM-standard dumbbells)
2. Set parameters:
   • Elongation: 2.0x (default for anti-vibration rubber)
   • Cycle target: 500,000 cycles
3. Initiate test: Cam-driven vertical stretching
4. Evaluate: Crack initiation/growth at intervals
