High-Performance Melt Flow Index Tester for Plastic Materials with
Dual Temperature Control and Automatic Cutting Control
Product Features:
- Built-in micro printer for test data printing.
- Dual temperature control with dual imported heating rings and PT100
platinum sensors enhances testing accuracy.
- Displacement sensor for MVR (volume method) testing, accuracy
0.01mm.
- MVR testing outputs directly without cutting.
- MVR testing range reaches 5000 cm³/10min with mold insertion.
- Material density at specific temp is calculated by MFR/MVR ratio.
- Cutting: manual/automatic one-machine operation.
- Insulation bucket of SUS304 stainless steel resists long-term
rusting.
