The Melt Flow Indexer (Manual Cut-Off) is a high-precision dead-weight extrusion plastometer designed for accurate melt flow rate (MFR) analysis of thermoplastic polymers.
This essential testing instrument features a thermostatically controlled melting chamber and a calibrated extrusion piston to ensure consistent heating and material flow.
By extruding resins through a standard die under specific load conditions, it provides reliable data for quality control and material characterization.
Ideal for plastics manufacturing and R&D, this durable indexer ensures your resins meet stringent international standards through precise, manual operation and robust engineering.
Frequently Asked Questions
What is a Melt Flow Indexer used for?
The Melt Flow Indexer measures the Melt Flow Rate (MFR) and Melt Volume Rate (MVR) of thermoplastic resins. This data helps manufacturers verify material consistency, grade polymers, and ensure raw materials meet specific processing requirements.
How does the manual cut-off mechanism work?
In this model, the operator manually cuts the extruded polymer at specific time intervals using a cutting tool. These samples are then weighed to calculate the flow rate, offering a cost-effective and hands-on approach to quality testing.
What standards does this instrument comply with?
This instrument is designed to meet international testing standards, including ASTM D1238 and ISO 1133. These standards ensure that the dead-weight extrusion method provides comparable data across the global plastics industry.
Does the unit come with calibrated weights?
Yes. The system includes a calibrated extrusion piston and a set of weights. Both components are manufactured to strict tolerances to ensure the pressure applied to the molten polymer is accurate and repeatable.
Which materials can be tested with this indexer?
It is suitable for a wide variety of polymers, including Polyethylene (PE), Polypropylene (PP), Polystyrene (PS), and ABS. It is an essential tool for both incoming material inspection and final product quality assurance.
