Description
EXTRUTEX EXCT-20 Co-Rotating Twin-Screw Extruder
EXTRUTEX EXCT-20 Co-Rotating Twin-Screw Extruder
Modular Twin-Screw Compounding Technology with Clamshell Barrel Design
The EXTRUTEX EXCT-20 is a modular co-rotating twin-screw extruder developed for demanding compounding, mixing, dispersion, devolatilization and material-processing applications. The machine is designed around a flexible modular concept that allows the processing configuration to be adapted to different materials and production requirements with relatively small changes to the screw elements and barrel sections.
The EXCT-20 combines a co-rotating twin-screw processing system, modular barrel construction, independently controlled temperature zones and a practical clamshell barrel design. This configuration provides operators and engineers with fast access to the screws and internal processing area, making product changes, cleaning, maintenance, troubleshooting and research and development considerably easier.
The modular philosophy behind the EXCT-20 allows one machine platform to be configured for a wide range of thermoplastic compounding applications, including polymer blending, filler incorporation, reinforcement, masterbatch production, additive dispersion, recycling compounds and other specialized formulations.
With its flexible processing architecture, the EXCT-20 can be configured according to the required combination of feeding, conveying, melting, mixing, kneading, dispersion, homogenization, degassing, pressurization and discharge.
Modular Processing Concept
The core advantage of the EXCT-20 is its modular construction.
Instead of relying on one fixed internal configuration, the extruder can be adapted by selecting suitable screw elements, kneading components and barrel sections for the material and process. This enables different processing tasks to be performed on the same basic extruder platform.
Depending on the formulation, individual processing zones can be designed for:
Material conveying
Feeding and pre-mixing
Polymer melting
Distributive mixing
Dispersive mixing
Kneading
Homogenization
Filler incorporation
Additive dispersion
Devolatilization and degassing
Pressure building
Melt filtration
Die feeding
Pelletizing or semi-finished product production
This modular approach is particularly valuable for manufacturers processing several formulations on the same production platform.
By changing the arrangement of screw elements and adjusting the barrel configuration, the EXCT-20 can be adapted to different material characteristics, processing temperatures, residence-time requirements, shear requirements and throughput targets.
Clamshell Barrel Design
One of the defining features of the EXCT-20 is its clamshell barrel construction.
The hinged barrel can be opened within a short period, providing direct access to the twin screws and internal processing zones. This design significantly simplifies operations that would otherwise require extensive dismantling of the extrusion system.
The clamshell arrangement is particularly useful during:
Product changeover
Screw inspection
Cleaning
Removal of residual material
Maintenance
Troubleshooting
Screw-element replacement
Process development
Research and development
Experimental formulation work
Fast access to the screws is important in compounding applications because different materials can have significantly different processing characteristics. Residual polymer, fillers, pigments or additives may need to be removed before another formulation is introduced.
The clamshell design allows operators to inspect and clean the processing area more conveniently while reducing unnecessary downtime.
For R&D environments, this feature is especially useful because screw configurations may be changed frequently during process development.
Independently Controlled Barrel Zones
The EXCT-20 uses a modular barrel system in which the individual barrel sections can be controlled according to the requirements of the process.
Each barrel zone can have its own temperature-control setting, allowing the temperature profile to be adapted along the processing direction.
This is important because a typical compounding process does not require one uniform temperature throughout the entire barrel.
Different zones may have different functions.
For example, the feeding section may require controlled temperature conditions to prevent premature melting or bridging, while the melting section can be operated at a higher temperature to facilitate polymer melting. Mixing zones may then require carefully controlled temperatures to maintain the desired melt viscosity, while downstream sections can be configured for degassing and pressure stabilization.
The independently controlled barrel zones provide engineers with greater control over:
Melting behavior
Melt viscosity
Mixing conditions
Residence time
Material dispersion
Thermal history
Degassing efficiency
Final melt temperature
Electric heating and cooling systems can be integrated with the barrel sections to provide controlled thermal management throughout the processing line.
Standard and Application-Specific Barrel Construction
The barrel sections of the EXCT-20 are designed according to the mechanical, thermal and chemical requirements of the intended application.
Standard barrel sections can be manufactured using suitable nitrided steel materials, while application-specific configurations can be supplied when higher wear resistance or corrosion resistance is required.
Material selection can be adapted according to the formulation being processed.
For example, compounds containing high levels of mineral fillers, glass fibers, calcium carbonate or other abrasive components can place significantly greater demands on the internal surfaces of the extruder.
Similarly, formulations containing aggressive additives or corrosive components may require different material solutions.
EXTRUTEX can therefore configure barrel and screw components according to the processing conditions and material requirements.
Flexible Screw and Kneading Element Configuration
The screw system is one of the most important components of a co-rotating twin-screw extruder.
The EXCT-20 uses a modular screw concept that allows individual screw elements and kneading components to be arranged according to the required process.
Different screw geometries can be selected to create specific processing zones.
Depending on the application, the screw configuration can include sections dedicated to:
Conveying
Conveying elements transport material through the barrel while controlling the filling level and residence time.
Melting
Special screw arrangements can promote controlled polymer melting and improve the transition from solid material to homogeneous melt.
Mixing
Mixing elements provide controlled distributive and dispersive mixing for polymer blends, fillers, pigments and additives.
Kneading
Kneading blocks can increase mixing intensity and improve the dispersion of additives or fillers.
Homogenization
Downstream screw configurations can be used to stabilize the melt and improve material uniformity before discharge.
Degassing
Dedicated screw sections can provide the conditions required for removing moisture, trapped air, volatile components and other unwanted gases.
Pressure Building
Conveying and compression sections near the discharge area can generate the pressure required for filtration, die feeding or pelletizing.
The modular screw design means that the processing system can be engineered around the material rather than forcing every formulation into the same fixed screw arrangement.
Compounding Process Configuration
The EXCT-20 can be configured for a complete sequence of processing operations.
1. Metering and Material Feeding
Accurate feeding is the starting point of a stable compounding process.
Different materials may require different feeding technologies depending on their physical characteristics, bulk density and formulation.
The feeding system can be configured for polymers, powders, pellets, fillers, fibers and additives.
Controlled metering helps maintain a stable formulation ratio and consistent production conditions.
2. Conveying and Material Transport
After entering the extruder, materials are transported through the modular screw system.
The conveying sections are designed to move the material efficiently while controlling filling level and residence time.
The screw configuration can be selected according to whether the application requires high conveying capacity, increased filling, longer residence time or controlled material transport.
3. Melting
The polymer must be converted into a homogeneous melt before intensive mixing and dispersion can take place.
The EXCT-20 can use a dedicated melting zone to introduce the required mechanical energy while maintaining controlled barrel temperatures.
The combination of screw geometry, barrel temperature and screw speed allows the melting process to be adapted to the polymer and formulation.
Controlled melting can help avoid unnecessary thermal degradation while maintaining stable processing conditions.
4. Dispersion and Homogenization
After melting, the material can pass through intensive mixing sections.
Dispersive mixing is used when solid particles, pigments, additives or other components need to be broken down and distributed throughout the polymer matrix.
Distributive mixing, meanwhile, promotes uniform distribution of the individual components throughout the melt.
The EXCT-20’s modular screw configuration allows engineers to balance these two mixing mechanisms according to the formulation.
This flexibility is particularly useful for:
Masterbatch
Filled compounds
Reinforced compounds
Polymer blends
Additive concentrates
Recycled polymer compounds
Specialty thermoplastic formulations
5. Degassing and Devolatilization
Many compounding applications require removal of moisture, air, residual monomers, solvents or other volatile components.
The EXCT-20 can incorporate dedicated degassing and devolatilization zones into the barrel configuration.
The screw arrangement in the degassing area can be designed to provide controlled melt exposure to the vacuum zone while maintaining appropriate material transport.
Vacuum-assisted devolatilization can improve the quality and stability of the final compound when volatile components or moisture are present.
The exact vacuum arrangement and degassing configuration can be adapted to the material and process requirements.
6. Pressure Building
Following mixing and degassing, the material must be transported toward the discharge section.
The downstream screw configuration can be designed to gradually stabilize the melt and generate the pressure required for the next stage.
Depending on the production system, the EXCT-20 can feed:
Strand pelletizing systems
Water-ring pelletizers
Underwater pelletizing systems
Melt filtration systems
Sheet or profile dies
Other downstream processing equipment
The pressure-building section can therefore be configured according to the requirements of the complete production line.
7. Melt Screening and Filtration
For applications involving recycled polymers or formulations containing potential contaminants, melt filtration can be an important part of the process.
The EXCT-20 can be integrated with an appropriate melt-screening system downstream of the extruder.
Screening helps remove unwanted solid contaminants before the melt enters the pelletizing or forming equipment.
The filtration configuration can be selected according to the material, contamination level, required filtration fineness and production conditions.
For recycling applications, this can be particularly important for improving the consistency and quality of the final recycled compound.
8. Pelletizing and Semi-Finished Product Production
The final stage of the process can be configured for pellet production or direct production of semi-finished materials.
Depending on the formulation and required product form, the EXCT-20 can be integrated with different downstream technologies.
Possible configurations include strand pelletizing, water-based pelletizing and other customized discharge arrangements.
The final system can therefore be designed as a complete production line rather than as an isolated extruder.
Applications
The EXTRUTEX EXCT-20 is suitable for a wide range of thermoplastic processing and compounding applications.
Potential applications include:
Polymer compounding
Polymer blending
Masterbatch production
Filler compounds
Calcium carbonate compounds
Mineral-filled compounds
Reinforced thermoplastics
Additive concentrates
Color masterbatch
Engineering plastics
Recycled polymer compounds
Reprocessing applications
Specialty formulations
Research and development
Laboratory and pilot-scale production
The final screw configuration, barrel arrangement, feeding system, temperature-control system and downstream equipment should be selected according to the specific material and production requirements.
Designed for Production and R&D
The EXCT-20 is not limited to high-volume industrial production.
Its modular architecture and clamshell barrel make it particularly practical for research and development environments, where frequent changes in formulations and screw configurations are required.
Engineers can test different processing concepts by modifying the screw arrangement and barrel zones without changing the complete extruder platform.
This provides a practical development path from laboratory and pilot trials toward industrial production.
The ability to access the screws quickly is another important advantage for development work. Experimental screw configurations can be inspected, changed and evaluated with reduced intervention time.
Mechanical Construction and Wear Protection
The screw and kneading components are manufactured from materials selected according to the intended processing conditions.
Standard configurations can use nitrided steel components, while higher wear resistance or corrosion resistance can be specified for demanding formulations.
This is particularly relevant when processing abrasive fillers, glass fibers, mineral additives or recycled materials containing contaminants.
The wear-resistant configuration can be engineered according to:
Material composition
Filler concentration
Processing temperature
Screw speed
Required service life
Corrosion conditions
Production capacity
EXTRUTEX can therefore provide different material and surface-treatment solutions according to the actual application.
Process Engineering by EXTRUTEX
A twin-screw extruder should not be selected only according to its motor power or screw diameter.
The actual performance of a compounding system depends on the relationship between the material formulation, feeding system, screw configuration, barrel temperature profile, screw speed, residence time, vacuum system, filtration and downstream equipment.
EXTRUTEX approaches the EXCT-20 as a complete process-engineering platform.
Our engineering team can evaluate the required material characteristics and processing objectives and develop an appropriate configuration for the application.
The modular design makes it possible to configure the processing zones around the product requirements, providing a flexible foundation for both standard and customized compounding systems.
