Laboratory Twin Screw Extruder for Polymer R&D, Lab Compounding, and Formula Trials
This laboratory twin screw extruder is built for polymer R&D teams that need repeatable lab compounding, additive screening, devolatilization trials, and small-batch scale-up data before committing to a production line.
- Laboratory twin screw extruder with 10-80 kg/h pilot range
- Lab scale twin screw extruder for masterbatch, additives, and recycled polymers
- Side feeding, venting, and modular screw sections for formulation development

Useful when lab compounding trials also need controlled sample reduction before drying, feeding, or formulation work.
Recycling Pelletizing Lines
Use this route when the project is moving from laboratory twin screw extrusion toward pilot or production-scale repelletizing.
How a Laboratory Twin Screw Extruder Is Typically Configured
The key buying decision is not only screw diameter. It is how feeding, screw elements, venting, and control zones are arranged for the exact lab compounding task.
1
Define the R&D Formulation Window
Start with the polymer family, additive package, filler load, temperature limits, and whether the trial is focused on dispersion, reactive extrusion, devolatilization, or masterbatch work.
2
Build the Screw and Feeding Layout
Configure conveying, kneading, mixing, side-feeding, and venting sections so the laboratory twin screw extruder behaves like a real process-development platform rather than a simple melting unit.
3
Run Controlled Lab Compounding Trials
Track torque, melt temperature, pressure, feed stability, and output condition across repeatable trial conditions to compare formulas and process windows.
4
Transfer the Data into Scale-Up Planning
Use the lab twin screw results to decide pilot throughput, barrel length, devolatilization strategy, and whether production should stay with twin screw compounding or move to a different extrusion route.

Equipment and Trial Output Showcase
Buyers usually compare both the machine configuration and the resulting melt or pellet behavior, not just the extruder frame.
Equipment View: Feeding and Barrel Configuration
A laboratory twin-screw system is usually selected around feeder positions, screw sections, venting points, and operator access for changeover.
- Clarifies where side feeding or liquid dosing is needed
- Helps define screw layout by dispersion or devolatilization task
- Improves repeatability between lab trials and pilot routing
Material View: Trial-Grade Compound Output
The real decision target is a stable test output that can be evaluated for dispersion, color, torque trend, pellet quality, or downstream converting behavior.
- Supports faster formulation comparison between trial runs
- Improves data quality for scale-up decisions
- Frames the extruder as a formulation tool instead of only a machine purchase
