Rumtoo Lab Extruder RLE-20Plus
Precision co-rotating twin-screw extruder engineered for advanced material research, polymer compounding, color masterbatch testing, and pilot-scale production. Innovate faster with reliable and flexible lab-scale formulation trials.
- Siemens PLC touch screen control and OMRON precision temperature regulation.
- Modular segmented screw & barrel design for quick L/D and geometry changes.
- Low material consumption (2–10 kg/h) ideal for high-cost experimental polymers.
Core Advantages
Designed to deliver industrial-scale compounding accuracy at research-scale sample volumes.
- Precision Control
Features Siemens PLC touch screen control and OMRON AI temperature units with PID self-tuning for high repeatability.
- Reliable Performance
Equipped with a premium WEG motor and a high-torque gearbox with forced lubrication for continuous operation.
- Modular Flexibility
The building-block screw element design allows easy geometry reconfigurations to suit various polymers and fillers.
- Durable Metallurgy
Constructed with high-strength 40CrNiMoA alloy steel shafts and nitrided barrels for maximum wear and corrosion resistance.
From Raw Material to Perfect Pellets
A complete automated pilot compounding workflow in four synchronized steps.
-
Step 1Metering & Feeding
Polymers, pigments, and additives are accurately dosed into the main feed throat by a precision twin-screw metering feeder.
-
Step 2Compounding & Extruding
Materials are thoroughly sheared, melted, homogenized, and degassed under vacuum in the co-rotating twin-screw barrel.
-
Step 3Cooling & Drying
The extruded polymer strands pass through a 2-meter stainless steel water bath for rapid cooling and an air knife for moisture removal.
-
Step 4Precision Pelletizing
The dried strands are cleanly cut into uniform, cylindrical granules by a high-speed variable-frequency strand pelletizer.
Detailed Engineering Features
Sub-system integration built to industrial compounding standards on a laboratory scale.
Advanced Control System
Siemens PLC and touch screen interface with OMRON AI temperature controllers and full interlock safety protection.
High-Performance Gearbox
