MFi-3G Melt Flow Indexer
The MFi-3G dual-temperature controlled intelligent melt flow indexer is designed to measure the melt flow rate of thermoplastic resins such as PE, PP and ABS. It adopts an independent closed-loop dual-temperature control system to keep the barrel temperature even and stable. The instrument supports both mass method (MFR) and volume method (MVR) testing, with automatic weighing, displacement acquisition, automatic cutting and data export functions. Equipped with a 7-inch Chinese-English touchscreen for intuitive and easy operation, it features a temperature range of 50℃–450℃ and temperature accuracy of ±0.2℃, suitable for routine testing in laboratories and production sites.
Product Details
Product Introduction：
The MFi-3G dual-temperature controlled intelligent melt flow indexer is designed for measuring the melt flow rate of thermoplastics. Its dual-zone temperature control keeps the barrel even and stable across a 50℃–450℃ range and accommodates multiple test loads.
Combining the mass method (MFR) and volume method (MVR) with manual and automatic cutting, its automatic weighing and displacement detection make testing smoother and results more objective. Featuring a 7-inch Chinese/English touchscreen, USB data export, printing and a burn-proof tool holder, the instrument is simple to operate and dependable in use, ideal for routine melt flow and flow-rate testing of PE, PP, ABS and other resins in laboratories and on the production floor.
Product Features：
As a standardized melt flow testing platform, the MFi-3G centers on an independent closed-loop dual-zone temperature control that regulates the barrel and piston region separately, suppressing axial temperature gradients and keeping the molten specimen at the isothermal state required by the test standard. A precision standard die and a range of traceable test loads ensure reproducible test conditions and comparable results across batches. The same hardware platform covers both measurement principles: the MFR mass method converts extruded mass per unit time through high-precision automatic weighing, while the MVR volume method derives melt volume flow rate from synchronized piston displacement acquisition and precision timing, so the two sets of results can cross-verify each other.
Automatic cutting, automatic weighing and displacement acquisition run through the entire test cycle together, minimizing random errors introduced by manual weighing and timing, and improving repeatability and reproducibility between batches. Test parameters, displacement curves and weighing records are stored centrally in the system and support data export and report printing, meeting the professional requirements of standardized laboratory management, quality-control comparison and report archiving.
