The Computer-controlled Explosion-proof Capillary Rheometer is a laboratory rheological testing instrument used to determine the melt flow behavior and apparent viscosity of plastics and polymer materials under controlled temperature, pressure, and shear conditions. The system integrates servo-driven loading, precision capillary dies, uniform heating, and computer-based measurement and control, enabling stable, repeatable, and standard-compliant rheological characterization for thermoplastics and thermosetting materials.
Application
(1) Measurement of apparent viscosity and shear rate characteristics of thermoplastic materials under specified temperature and shear stress conditions.
(2) Rheological characterization of thermosetting polymer melts during controlled extrusion through capillary dies.
(3) Evaluation of melt flow behavior under constant pressure, constant speed, constant temperature, or variable heating rate conditions.
(4) Comparative analysis of polymer processing performance for extrusion, injection molding, and compounding processes.
(5) Research and development of new polymer formulations, additives, and modified materials.
(6) Quality control and batch consistency verification in polymer manufacturing.
(7) Rheological testing for academic research, industrial laboratories, and material certification institutions.
Standards
(1) HG/T 4300-2012 — Capillary Rheometer Test Method for Plastics
(2) ISO 11443 — Plastics — Determination of the Fluidity of Plastics Using Capillary and Slit-Die Rheometers
(3) ASTM D3835 — Standard Test Method for Determination of Rheological Properties of Thermoplastics Using a Capillary Rheometer
(4) DIN 54811 — Plastics — Determination of Flow Behavior Using Capillary Rheometers
(5) GB/T 21060 — Plastics — Determination of Melt Rheological Properties (Capillary Method)
Features
(1) Computer-controlled measurement and control system enabling automatic test parameter configuration and data acquisition.
(2) Single-column, single-indenter structure with explosion-proof design for safe operation.
(3) AC servo drive combined with precision ball screw transmission for accurate displacement and pressure control.
(4) Uniform barrel heating using integrated spiral heating wire to ensure temperature stability along the flow path.
(5) Supports constant pressure, constant speed, constant temperature, and variable heating rate test modes.
(6) Automatic generation of rheological curves with real-time display, storage, and printing functions.
(7) Modular and customizable design for temperature range, pressure capacity, indenter diameter, and die specifications.
(8) Intuitive software interface for parameter setting, test execution, and result analysis.
