The Capillary Rheometer is a computer-controlled laboratory instrument used for determining the rheological properties of molten plastics and polymer materials under controlled temperature, pressure, and shear conditions. The instrument measures shear rate, melt flow behavior, and apparent viscosity by forcing molten material through precision capillary dies. It adopts a single-column, single-indenter structure with integrated heating and servo-driven loading, ensuring stable operation, accurate measurement, and compliance with international testing standards.
Application
(1) Measurement of shear rate and apparent viscosity of thermoplastic materials under specified temperature and shear stress conditions.
(2) Determination of melt flow characteristics of thermosetting polymer materials during controlled extrusion.
(3) Rheological evaluation under constant pressure, constant speed, constant temperature, and variable heating rate conditions.
(4) Comparative analysis of processing performance for extrusion and injection molding applications.
(5) Research and development of polymer formulations, modifiers, and additives.
(6) Quality control and batch consistency verification in polymer manufacturing.
(7) Rheological testing for industrial laboratories, academic research, and material certification institutions.
Standards
(1) DIN 54811 — Plastics — Determination of Flow Behavior Using Capillary Rheometers
(2) ASTM D3835 — Standard Test Method for Determination of Rheological Properties of Thermoplastics Using a Capillary Rheometer
(3) ISO 11443 — Plastics — Determination of the Fluidity of Plastics Using Capillary and Slit-Die Rheometers
System Composition
(1) Single-column swing-head frame structure ensuring mechanical strength and convenient cleaning.
(2) Precision transmission system using Taiwan-brand ball screw for accurate force and displacement transfer.
(3) AC servo drive system providing precise speed and pressure control.
(4) Integrated barrel heating unit using spiral heating wire to ensure uniform temperature distribution.
(5) High-precision pressure and displacement sensing system.
(6) Computer-based measurement and control system with real-time data acquisition and analysis software.
(7) User interface enabling test mode selection, parameter configuration, curve display, data storage, and printing.
