Rubber & Plastic Testing Machine

Precision Melt Flow Analysis for Thermoplastics

The SUNRISE XNR-400 Series determines Melt Mass-Flow Rate (MFR) and Melt Volume-Flow Rate (MVR) for plastics (PE, PP, PC, ABS, etc.) with ±0.2°C temperature control and 8 standardized test loads (0.325-21.6kg).

H2: Key Features

✔ Dual-Mode Testing: MFR (manual cut) & MVR (piston displacement)
✔ Industrial-Grade Components: Hastelloy-nitrided barrel + tungsten carbide die
✔ High Accuracy: 0.1°C resolution (±0.2°C accuracy)
✔ OEM Ready: Pre-loaded ISO 1133, ASTM D1238, and GB/T 3682 protocols

H3: Technical Specifications

H2: Compliance & Applications

Standards:

• ISO 1133-1:2011 (MFR/MVR)
• ASTM D1238-20 (Thermoplastics flow rates)
• GB/T 3682-2018 (China MFR standard)

Use Cases:

• Polymer manufacturing QC
• Recycled plastic quality validation
• Automotive/electronics material R&D

H3: Testing Workflow

Method A (MFR):

1. Load material into barrel (pre-heated to set temp)
2. Apply weight: 2.16kg (default for PP)
3. Cut extrudate manually at intervals → weigh (g/10min)

Method B (MVR):

1. Initiate auto-test: Piston displacement tracking
2. Calculate: Volume flow (cm³/10min) via sensor
