Laboratory Twin Screw Extruder HTE20
The HTE20 laboratory twin screw extruder from Nanjing Hundred Horse is designed for trial-level production, material development, formulation testing, and small-batch masterbatch manufacturing. With compact dimensions, modular screw and barrel design, and stable process control, it provides an efficient solution for laboratories, research centers, universities, and manufacturers developing new plastic compounds.
This lab extruder is especially suitable for color masterbatch, additive masterbatch, filler masterbatch, engineering plastics, and polymer compounding applications where accurate testing, easy cleaning, and low material consumption are required.
Compact Design for Flexible Laboratory Processing
The HTE20 laboratory extruder is built for users who need reliable extrusion performance in a limited working space. Its compact structure makes it suitable for laboratory platforms and small production areas, while its modular configuration allows the machine to be adapted to different formulas and process requirements.
Only standard power supply is required for operation, making the system practical for laboratory environments and entry-level production. For specific applications, Nanjing Hundred Horse can optimize the screw configuration, barrel arrangement, feeding method, and downstream equipment according to the customer’s material formula and processing target.
Key Features
- Modular screw and barrel design: Screw elements and barrels can be configured according to different materials, recipes, and processing requirements.
- Easy cleaning and formula change: The split-type structure allows quick dismantling, easy observation, and convenient cleaning after trials.
- Low material consumption: Ideal for formula development, small-batch testing, and cost-effective R&D work.
- Compact footprint: Requires less installation space and can be placed in laboratory or pilot-scale production environments.
- Flexible process optimization: Suitable for testing different screw combinations, process temperatures, feeding ratios, and material behaviors.
- Stable data collection: Helps operators record processing parameters and compare test results during formulation development.
- Optional high-torque gearbox: Available for customers who require higher output or stronger processing capability.
Applications
The HTE20 laboratory twin screw extruder is suitable for a wide range of plastic material development and masterbatch testing applications, including:
- Color masterbatch development
- Additive masterbatch trials
- Filler masterbatch formulation
- Polymer compounding research
- Engineering plastic modification
- Small-batch sample production
- Raw material evaluation and quality control
- University, laboratory, and R&D center testing
Designed for Formula Development and Process Observation
In laboratory extrusion, process visibility and repeatability are essential. The HTE20 is designed to help operators observe the processing behavior of polymers inside the barrel, adjust screw combinations, and collect useful processing data during each trial.
Compared with larger production extruders, the laboratory extruder uses less material and allows faster trial cycles. This helps manufacturers reduce development cost, shorten testing time, and improve the accuracy of scale-up before moving to commercial production.
