Rubber & Plastic Testing Machine

Advanced Vulcanization Analysis for Rubber Compounds

The SUNRISE SR-321 delivers precise scorch time (ts1/ts2), cure rate (Vc1/Vc2), and torque (ML-MH) measurements with 0.001N·m resolution and ±0.3°C temperature control, ideal for tire, seal, and rubber product R&D.

H2: Key Features

✔ Multi-Torque Ranges: 0-5/10/20N·m (user-selectable)
✔ Precision Engineering: SKD-11 steel dies + NSK bearings for durability
✔ Smart PID Control: Auto-corrects heating parameters for ±0.3°C stability
✔ OEM Ready: Pre-loaded ISO 6502, ASTM D5289, and GB/T 16584 protocols

H3: Technical Specifications

H2: Compliance & Applications

Standards:

• ISO 6502:2023 (Rotorless cure meters)
• ASTM D5289-19 (Rubber vulcanization)
• GB/T 16584-2020 (China MDR standard)

Use Cases:

• Tire tread compound optimization
• Rubber gasket cure time validation
• Reclaimed rubber quality control

H3: Testing Workflow

1. Load sample into die cavity (pre-heated to test temp)
2. Set parameters:
   • Torque range: 10N·m (default for tire compounds)
   • Oscillation: 100 RPM @ ±0.5°
3. Initiate test: Real-time torque/temp curve generation
4. Analyze: Auto-calculated ts1, t90, and cure rate indices
