TSE-20
HS
Lab extruder : Due to the co-rotating twin-screw has the opposite speed at the meshing point, one screw pulls the material into the meshing gap, and the other screw pushes the material out of the gap, resulting in material from one screw turns to the other screw and advances in a "∞" shape. Since the gap of the meshing zone is small, the speed of the meshing screw and the groove are opposite in direction, so that the cutting speed is high, and the self-cleaning effect is good, that is, any accumulated material adhering to the screw can be scraped off, thereby The residence time of the material is very short, so the twin screw extruder is mainly used for compounding and pelletizing .

Laboratory Pelletizing Extruder – Frequently Asked Questions (Q&A)
Q1: What is a laboratory extruder?
A laboratory extruder is a small-scale plastic pelletizing machine designed for material testing, formula development, and small-batch trial production.
Unlike large industrial pelletizing lines, it focuses on precision, flexibility, and data accuracy, rather than high output.
At HAISI EXTRUSION, laboratory extruders are mainly used for compound pelletizing, not for profiles, sheets, or films.
Q2: What is the difference between a laboratory extruder and an industrial pelletizing extruder?
Both machines work on the same extrusion principle, but they serve different purposes.
Laboratory pelletizing extruder
Output: approx. 0.25–150 kg/h
Purpose: testing, formulation development, process validation
Advantages: flexible configuration, quick material change, precise control
Industrial pelletizing extruder
Output: hundreds to thousands of kg/h
Purpose: continuous mass production
Advantages: high efficiency, stability, labor savings
In short:
Lab extruders are for learning and testing; industrial extruders are for volume production.
Q3: What are laboratory pelletizing extruders mainly used for?
Typical applications include:
Testing new plastic formulations
Masterbatch and filler compound trials
Recycled material evaluation
Foaming material experiments
Color matching and dispersion testing
University and R&D institute teaching
Pilot-scale pellet production before mass manufacturing
All outputs are plastic pellets, not finished plastic products.
Q4: Why do companies choose a laboratory pelletizing extruder?
Because it helps reduce risk and cost.
Main reasons include:
Avoid wasting expensive raw materials on large machines
Quickly adjust screw design and process parameters
Verify material behavior before scaling up
Generate reliable data for industrial pelletizing lines
Support R&D without interrupting factory production
For many customers, a lab extruder is a “decision-making tool”, not just a machine.
Q5: What sizes of laboratory pelletizing extruders are commonly used?
Laboratory extruders are typically classified by screw diameter:
Micro lab extruders (12–16 mm)
Very small material consumption
High-frequency testing
Teaching and early-stage R&D
Standard lab extruders (16–35 mm)
Most common choice
Process validation and formulation optimization
Pilot-scale extruders (25–45 mm)
Equipped with pelletizing systems
Used for customer sampling and pre-production trials
All of these are still considered pelletizing machines, not full industrial lines.
Q6: What key parameters should customers focus on when selecting a lab pelletizing extruder?
1. Screw diameter & L/D ratio
Larger L/D ratio = better mixing and dispersion
L/D ≥ 40 is preferred for fillers, additives, or reactive extrusion
2. Output range
Small output = low material cost per test
Pilot output = closer to real production conditions
3. Modular design
Allows quick replacement of screws, barrels, vents, and dies
Ideal for customers who test many materials
4. Control system (PLC + HMI)
Accurate temperature, torque, and pressure control
Data recording for scale-up and technical reports
Q7: What auxiliary systems are commonly used with laboratory pelletizing extruders?
Depending on the material and test goal, lab extruders may include:
Side feeders for fillers or fibers
Vacuum venting for moisture and volatiles
Strand pelletizing systems
Water-ring pelletizing systems
Air-cooling pelletizing systems
All configurations are focused on pellet quality, not final product shaping.
Q8: Can a laboratory pelletizing extruder be used for small production?
Yes, but with limitations.
Some customers use pilot-scale lab extruders for:
Small-batch specialty compounds
High-value or customized materials
Trial market supply before mass production
However, it is not a replacement for an industrial pelletizing line.
Q9: Is a laboratory extruder suitable for customers without recycling or compounding experience?
Yes.
Many customers start with limited technical knowledge.
A properly configured lab pelletizing extruder allows them to:
Understand material behavior step by step
Avoid over-investment
Build experience before scaling up
This is why lab extruders are often the first machine in a long-term pelletizing strategy.
Q10: How does a laboratory pelletizing extruder help future industrial production?
It provides real, reliable reference data such as:
Torque load
Melt stability
Dispersion quality
Venting effectiveness
These results are critical when selecting or designing an industrial pelletizing extruder later.
The Extruder for Lab Research and Trainings is designed for educational and experimental use, offering precise control and flexibility for studying polymer processing, compounding, and extrusion techniques.
The Laboratory Twin Screw Extruder for Testing Polymer is designed for material testing and formulation development, offering precise control, reliable mixing, and stable extrusion performance.
The TSE-20 Twin Screw Extruder Machine for Lab Uses is designed for laboratory research and small-scale testing, offering precise control, stable performance, and reliable compounding of various polymer materials.
