Melt Flow Tester CEAST MF50

The Instron® CEAST MF50 multi-weight Melt Flow Tester performs
melt flow rate (melt index) tests according to MFR and MVR methods
that fully comply with ASTM D1238 procedures A, B, C, D, and ISO
1133 A and B, for single weight and multiple weight tests .
Multi-weight tests can include up to 5 masses in increasing,
decreasing or free sequence, with fully customizable preheating
and measurement steps. All masses are pre-installed and managed
by the machine without operator intervention, eliminating all safety
concerns. A high-resolution direct-contact encoder measures piston
displacement. The temperature profile in the barrel is extremely
stable and accurate. Additional advanced features include a large
touch-screen display for full test programming, management and
diagnostic functions, with an embedded PC based on Windows CE,
able to store test methods and test results. Easy data export through
USB and Ethernet ports. Compacting and purging functions can be
supported by the unique load cell feature. Automatic melt cutting and
barell cleaning accessories are also available.

• Oven-mounted tilting support for easy cleaning and inspection of tt
t the barrel by the operator
• Equipped with a fully automatic system for loading masses onto the t
t piston, enabling single-weight and multi-weight tests
• Eight different masses, ranging from 0.325 - 21.6 kg, remain tt
t installed at all times
• Multi-weight measurements can be carried out with up to 5 weights t
t in the same test, following an increasing, decreasing or
t free sequence
• High-resolution numerical control lifting for quick and accurate tt
t weight application
• High accuracy encoder ensures great results, precision with up to tt
t 50 measurement points in one test
• A powerful, fully integrated, semi-automatic cleaning system for tt
t quick, easy, and effective cleaning can be added to the instrument
• A die plug device is available for high fluidity materials testing, to tt
t prevent material drool before test starting, equipped with a
t micro-switch. A pneumatic version with automatic opening is
t also available.
• Unique load cell feature for effective and reproducible material tt
t compacting, as well as purging at test end, with up to 750 N force.
• Special dies according to specific procedures can be supplied
t (for example ASTM D 3364 for PVC)
• Can be configured with a Piston Holding device to remove any load t
t from the piston during resting phase prior to measurements.
