LAB TWIN SCREW EXTRUDER

LAB TWIN SCREW EXTRUDER

The lab co-rotating twin screw extruder serves as the “versatile workhorse” of the R&D laboratory. Its modular design, extensive parameter adjustment range, precise process control, robust data acquisition capabilities, and small-batch processing characteristics endow it with unparalleled R&D flexibility, efficiency, and functionality. It significantly accelerates the development of new materials, formulation optimization, and process exploration, acting as an indispensable bridge connecting laboratory research to industrial production.

1. Temperature Control:Each barrel segment features independent temperature control (via electric heating, oil heating, or water cooling), offering high precision (±1°C or better) and a wide temperature range (100-400°C).
2. FeedingSystem: Equipped with high-precision loss-in-weight or volumetric feeders (for main feed, side feed, liquid injection pumps), enabling precise control of feed rates and ratios for multiple components (powders, pellets, liquids).
3. Vacuum/Venting System: Allows for multiple vacuum or atmospheric venting ports positioned along the barrel to remove moisture, solvents, and low-molecular-weight volatiles (devolatilization).
4. PressureMeasurement: A melt pressure sensor is installed at the die head for real-time monitoring.
5. Small-BatchProcessing Capability: Designed to handle gram-to-kilogram quantities of material, making it ideal for expensive, rare, or early-stage R&D materials.
6. Powerful Data Acquisition & Monitoring: Incorporates an advanced PLC control system for real-time acquisition, recording, and display of all critical process parameters (screw speed, torque, barrel temperatures, melt pressure, feed rates, vacuum level, etc.). Enables storage of process profiles for easy experiment replication and data analysis.
7. Scale-Up Simulation:Its operating principle is highly consistent with large-scale production machines, making experimental results crucially valuable for guiding industrial scale-up.
8. Ease of Cleaning & Maintenance:The modular design facilitates quick and easy disassembly, cleaning, and replacement of screws and barrel sections, minimizing cross-contamination between batches and downtime. Features excellent self-cleaning due to the mutual wiping action of the co-rotating screws, reducing material residue.
