Description
EXTRUTEX ECK-200 Co-Kneader Extruder
EXTRUTEX ECK-200 Co-Kneader Extruder – Professional Low-Shear Compounding System
The EXTRUTEX ECK-140 Co-Kneader Extruder is a high-capacity continuous polymer compounding system designed for large-scale industrial production where high throughput, excellent mixing, controlled temperature and consistent compound quality are essential.
With a 140 mm screw diameter, 220 kW drive power, maximum screw speed of 500 rpm and an output capacity of approximately 800–1000 kg/h, the ECK-140 is designed for demanding commercial production of color masterbatch, engineering plastics, polyester compounds, high-filler formulations, flame-retardant compounds and other specialty polymer materials.
The ECK-140 uses the proven Co-Kneader processing principle, combining continuous screw rotation with reciprocating axial movement. The screw works together with stationary kneading pins inside the barrel to create highly efficient dispersive and distributive mixing.
This technology allows the ECK-140 to process large quantities of polymer while maintaining controlled mechanical and thermal conditions.
For manufacturers requiring a production capacity approaching one metric ton per hour, the ECK-140 provides a powerful platform for continuous industrial compounding.

| Parameter | ECK-140 |
|---|---|
| Model | ECK-140 |
| Screw Diameter | 140 mm |
| L/D Ratio | 10–25 |
| Reciprocating Stroke | 21 mm |
| Drive Power | 220 kW |
| Maximum Screw Speed | 500 rpm |

The ECK-140 can be configured according to the polymer, formulation, filler loading, additive system, required production capacity and downstream pelletizing process.
Advanced Co-Kneader Technology for Large-Scale Production
The ECK-140 is based on a specialized Co-Kneader principle that combines rotational screw movement with reciprocating axial movement.
Unlike conventional extrusion systems where the screw primarily rotates in a fixed position, the ECK-140 continuously moves the screw forwards and backwards inside the processing chamber.
This reciprocating action changes the position of the kneading flights relative to the stationary pins and creates additional material movement throughout the barrel.
As the polymer passes through the machine, it is continuously:
- Divided
- Folded
- Stretched
- Recombined
- Redistributed
- Homogenized
- Transported forward
This creates a highly effective mixing process while helping maintain controlled shear and temperature conditions.
For large-scale production, the combination of efficient mixing and high throughput makes the ECK-140 suitable for continuous industrial operation.
Rotating and Reciprocating Screw System
The specially engineered screw is one of the most important components of the ECK-140.
During operation, the screw performs two coordinated movements.
The first is rotational movement, which provides material transport and continuous kneading.
The second is reciprocating axial movement, which repeatedly changes the relationship between the screw flights and the stationary kneading pins.
The 21 mm reciprocating stroke provides substantial axial movement inside the processing chamber, creating additional folding and redistribution of the polymer.
This movement helps prevent material from simply following a direct forward path through the machine.
Instead, the material is repeatedly renewed around the kneading elements, promoting excellent homogenization and consistent additive distribution.
The EXTRUTEX ECK-200 Co-Kneader Extruder is a high-capacity industrial compounding system designed for large-scale production of polymer compounds, masterbatch, highly filled formulations, engineering plastics, PVC compounds, flame-retardant materials, and other specialty polymer formulations.
With a 200 mm screw diameter, 30 mm reciprocating stroke, 355 kW drive system and maximum screw speed of 500 rpm, the ECK-200 is designed for demanding continuous production environments where high throughput, controlled mixing, efficient heat management and reliable long-term operation are required.
The ECK-200 provides a production capacity of approximately 4,000–5,000 kg/h, making it suitable for large masterbatch and polymer-compounding plants where production volume and process consistency are critical.
Unlike conventional extrusion systems that rely primarily on continuous screw rotation, the ECK Co-Kneader combines rotating and reciprocating screw movement with stationary kneading pins. This creates intensive yet controlled mixing while maintaining a relatively low melt temperature and minimizing unnecessary mechanical stress on temperature-sensitive materials.

The ECK-200 can be configured according to the polymer, formulation, filler content, additives, feeding system and required production capacity. EXTRUTEX can also adapt the process section and auxiliary equipment to meet specific production requirements.
Advanced Co-Kneader Technology
The ECK-200 is based on the proven Co-Kneader compounding principle, where the screw performs both rotational and axial reciprocating movement.
The combination of these two movements creates repeated kneading and mixing actions between the screw flights and stationary kneading pins. This allows the material to be continuously divided, folded, dispersed and redistributed throughout the processing chamber.
For high-throughput applications, this operating principle provides several important advantages:
- Efficient dispersion of additives and fillers
- Excellent distributive mixing
- Controlled dispersive mixing
- Relatively low melt temperature
- Efficient heat transfer
- High filler-loading capability
- Effective incorporation of liquid components
- Reduced material residence in stagnant areas
- Stable continuous production
The ECK-200 is particularly suitable for industrial formulations where maintaining material quality while processing several tons per hour is essential.
Rotating and Reciprocating Screw System
The main processing screw of the ECK-200 performs simultaneous rotation and reciprocation.
The rotational movement transports the polymer through the processing section, while the reciprocating movement repeatedly brings the material into contact with the kneading elements and stationary pins.
This produces a controlled kneading effect throughout the material.
The 30 mm reciprocating stroke of the ECK-200 provides substantial axial movement during the compounding process. Combined with a maximum screw speed of 500 rpm, the system can deliver intensive processing while maintaining control over residence time, temperature and dispersion.
The screw configuration can be adapted to different formulations, allowing the ECK-200 to process materials with different viscosity, filler concentration and additive requirements.
Stationary Kneading Pin System
A major characteristic of the ECK system is its use of stationary kneading pins positioned around the processing chamber.
As the screw rotates and reciprocates, the polymer passes repeatedly through the spaces between the screw and the stationary pins.
This creates multiple mixing zones along the processing path.
The stationary pins contribute to:
- Material splitting and recombination
- Filler dispersion
- Additive distribution
- Polymer homogenization
- Improved heat transfer
- Controlled kneading
- Reduction of unmixed material
The processing geometry can be selected according to the formulation and production requirements.
Low-Shear Polymer Processing
One of the important advantages of Co-Kneader technology is the ability to achieve effective compounding without relying exclusively on extremely high shear.
The ECK-200 is therefore suitable for materials that require controlled thermal and mechanical processing.
The system can help reduce unnecessary temperature increases caused by excessive mechanical energy while still providing efficient mixing.
This is particularly valuable when processing:
- Heat-sensitive polymers
- Color masterbatch
- PVC compounds
- Filled polymer systems
- Flame-retardant compounds
- Engineering plastics
- Specialty polymer formulations
The combination of controlled kneading and efficient heat transfer helps maintain stable processing conditions during high-volume production.
Dispersive and Distributive Mixing
The ECK-200 is designed to provide both dispersive and distributive mixing.
Dispersive mixing helps break down agglomerates of pigments, fillers and additives, while distributive mixing ensures that these components are distributed uniformly throughout the polymer matrix.
This combination is important for achieving consistent final product properties.
For masterbatch production, efficient dispersion of pigments and additives is essential for achieving consistent color strength and concentration.
For filled compounds, effective distribution of mineral fillers and other additives helps maintain uniform material characteristics throughout the production batch.
High Degree of Self-Wiping
The Co-Kneader processing geometry provides a high degree of self-wiping action.
Material continuously moves through the active processing areas, helping to reduce material accumulation and stagnant zones.
This can be particularly beneficial when processing:
- Highly filled compounds
- Pigmented formulations
- Additive-rich compounds
- Sticky polymer systems
- Color masterbatch
- Specialty formulations
Reduced material accumulation can also simplify cleaning and reduce the risk of contamination when changing between different formulations.
High Filler Loading Capability
The ECK-200 is suitable for formulations containing significant quantities of mineral fillers and other solid additives.
Depending on the formulation and feeding system, the Co-Kneader principle can efficiently incorporate materials such as:
- Calcium carbonate
- Talc
- Calcium sulfate
- Glass fibers
- Mineral fillers
- Flame-retardant additives
- Wood-based fillers
- Other functional powders
The screw and kneading configuration can be designed to provide controlled incorporation of high filler concentrations while maintaining stable material transport and mixing.
For large-scale production of filled compounds, this makes the ECK-200 a suitable platform for continuous industrial compounding.
Low-Shear Polymer Processing
One of the important advantages of Co-Kneader technology is the ability to achieve effective compounding without relying exclusively on extremely high shear.

The screw and kneading configuration can be designed to provide controlled incorporation of high filler concentrations while maintaining stable material transport and mixing.
For large-scale production of filled compounds, this makes the ECK-200 a suitable platform for continuous industrial compounding.
Efficient Liquid Component Incorporation
Liquid additives can be introduced at selected points within the processing section.
The controlled kneading action helps incorporate liquid components into the polymer melt and distribute them throughout the formulation.
Depending on the application, liquid feeding may be used for:
- Plasticizers
- Processing aids
- Liquid additives
- Reactive components
- Lubricants
- Other formulation ingredients
The feeding location and injection configuration can be selected according to the material formulation and process requirements.
Temperature Control

The ECK-200 can be equipped with controlled cooling and heating zones to maintain stable processing temperatures throughout the barrel.
Efficient temperature management helps control:
- Polymer melt temperature
- Viscosity
- Residence conditions
- Additive stability
- Product consistency
- Thermal degradation
The processing temperature profile can be adapted according to the polymer and formulation.
For temperature-sensitive materials, controlled cooling is particularly important because excessive melt temperature can negatively affect color, viscosity, mechanical properties and long-term material performance.
Easy Cleaning and Maintenance
For large-scale compounding plants, cleaning and maintenance are important factors in overall production efficiency.
The ECK-200 is designed with accessibility to the processing components to facilitate inspection, cleaning and maintenance.

The ECK-140 can be configured according to the polymer, formulation, filler loading, additive system, required production capacity and downstream pelletizing process.
Advanced Co-Kneader Technology for Large-Scale Production
The ECK-140 is based on a specialized Co-Kneader principle that combines rotational screw movement with reciprocating axial movement.
Unlike conventional extrusion systems where the screw primarily rotates in a fixed position, the ECK-140 continuously moves the screw forwards and backwards inside the processing chamber.
This reciprocating action changes the position of the kneading flights relative to the stationary pins and creates additional material movement throughout the barrel.
As the polymer passes through the machine, it is continuously:
- Divided
- Folded
- Stretched
- Recombined
- Redistributed
- Homogenized
- Transported forward
This creates a highly effective mixing process while helping maintain controlled shear and temperature conditions.
For large-scale production, the combination of efficient mixing and high throughput makes the ECK-140 suitable for continuous industrial operation.
Rotating and Reciprocating Screw System
The specially engineered screw is one of the most important components of the ECK-140.
During operation, the screw performs two coordinated movements.
The first is rotational movement, which provides material transport and continuous kneading.
The second is reciprocating axial movement, which repeatedly changes the relationship between the screw flights and the stationary kneading pins.
The 21 mm reciprocating stroke provides substantial axial movement inside the processing chamber, creating additional folding and redistribution of the polymer.
This movement helps prevent material from simply following a direct forward path through the machine.
Instead, the material is repeatedly renewed around the kneading elements, promoting excellent homogenization and consistent additive distribution.
The EXTRUTEX ECK-200 Co-Kneader Extruder is a high-capacity industrial compounding system designed for large-scale production of polymer compounds, masterbatch, highly filled formulations, engineering plastics, PVC compounds, flame-retardant materials, and other specialty polymer formulations.
With a 200 mm screw diameter, 30 mm reciprocating stroke, 355 kW drive system and maximum screw speed of 500 rpm, the ECK-200 is designed for demanding continuous production environments where high throughput, controlled mixing, efficient heat management and reliable long-term operation are required.
The ECK-200 provides a production capacity of approximately 4,000–5,000 kg/h, making it suitable for large masterbatch and polymer-compounding plants where production volume and process consistency are critical.
Unlike conventional extrusion systems that rely primarily on continuous screw rotation, the ECK Co-Kneader combines rotating and reciprocating screw movement with stationary kneading pins. This creates intensive yet controlled mixing while maintaining a relatively low melt temperature and minimizing unnecessary mechanical stress on temperature-sensitive materials.

Advanced Co-Kneader Technology
The ECK-200 is based on the proven Co-Kneader compounding principle, where the screw performs both rotational and axial reciprocating movement.
The combination of these two movements creates repeated kneading and mixing actions between the screw flights and stationary kneading pins. This allows the material to be continuously divided, folded, dispersed and redistributed throughout the processing chamber.
For high-throughput applications, this operating principle provides several important advantages:
- Efficient dispersion of additives and fillers
- Excellent distributive mixing
- Controlled dispersive mixing
- Relatively low melt temperature
- Efficient heat transfer
- High filler-loading capability
- Effective incorporation of liquid components
- Reduced material residence in stagnant areas
- Stable continuous production
The ECK-200 is particularly suitable for industrial formulations where maintaining material quality while processing several tons per hour is essential.
Rotating and Reciprocating Screw System
The main processing screw of the ECK-200 performs simultaneous rotation and reciprocation.
The rotational movement transports the polymer through the processing section, while the reciprocating movement repeatedly brings the material into contact with the kneading elements and stationary pins.
This produces a controlled kneading effect throughout the material.
The 30 mm reciprocating stroke of the ECK-200 provides substantial axial movement during the compounding process. Combined with a maximum screw speed of 500 rpm, the system can deliver intensive processing while maintaining control over residence time, temperature and dispersion.
The screw configuration can be adapted to different formulations, allowing the ECK-200 to process materials with different viscosity, filler concentration and additive requirements.
Stationary Kneading Pin System
A major characteristic of the ECK system is its use of stationary kneading pins positioned around the processing chamber.
As the screw rotates and reciprocates, the polymer passes repeatedly through the spaces between the screw and the stationary pins.
This creates multiple mixing zones along the processing path.
The stationary pins contribute to:
- Material splitting and recombination
- Filler dispersion
- Additive distribution
- Polymer homogenization
- Improved heat transfer
- Controlled kneading
- Reduction of unmixed material
The processing geometry can be selected according to the formulation and production requirements.
Low-Shear Polymer Processing
One of the important advantages of Co-Kneader technology is the ability to achieve effective compounding without relying exclusively on extremely high shear.
The ECK-200 is therefore suitable for materials that require controlled thermal and mechanical processing.
The system can help reduce unnecessary temperature increases caused by excessive mechanical energy while still providing efficient mixing.
This is particularly valuable when processing:
- Heat-sensitive polymers
- Color masterbatch
- PVC compounds
- Filled polymer systems
- Flame-retardant compounds
- Engineering plastics
- Specialty polymer formulations
The combination of controlled kneading and efficient heat transfer helps maintain stable processing conditions during high-volume production.
Dispersive and Distributive Mixing
The ECK-200 is designed to provide both dispersive and distributive mixing.
Dispersive mixing helps break down agglomerates of pigments, fillers and additives, while distributive mixing ensures that these components are distributed uniformly throughout the polymer matrix.
This combination is important for achieving consistent final product properties.
For masterbatch production, efficient dispersion of pigments and additives is essential for achieving consistent color strength and concentration.
For filled compounds, effective distribution of mineral fillers and other additives helps maintain uniform material characteristics throughout the production batch.
High Degree of Self-Wiping
The Co-Kneader processing geometry provides a high degree of self-wiping action.
Material continuously moves through the active processing areas, helping to reduce material accumulation and stagnant zones.
This can be particularly beneficial when processing:
- Highly filled compounds
- Pigmented formulations
- Additive-rich compounds
- Sticky polymer systems
- Color masterbatch
- Specialty formulations
Reduced material accumulation can also simplify cleaning and reduce the risk of contamination when changing between different formulations.
High Filler Loading Capability
The ECK-200 is suitable for formulations containing significant quantities of mineral fillers and other solid additives.
Depending on the formulation and feeding system, the Co-Kneader principle can efficiently incorporate materials such as:
- Calcium carbonate
- Talc
- Calcium sulfate
- Glass fibers
- Mineral fillers
- Flame-retardant additives
- Wood-based fillers
- Other functional powders
The screw and kneading configuration can be designed to provide controlled incorporation of high filler concentrations while maintaining stable material transport and mixing.
For large-scale production of filled compounds, this makes the ECK-200 a suitable platform for continuous industrial compounding.
Low-Shear Polymer Processing
One of the important advantages of Co-Kneader technology is the ability to achieve effective compounding without relying exclusively on extremely high shear.

This is particularly valuable when processing:
- Heat-sensitive polymers
- Color masterbatch
- PVC compounds
- Filled polymer systems
- Flame-retardant compounds
- Engineering plastics
- Specialty polymer formulations
The combination of controlled kneading and efficient heat transfer helps maintain stable processing conditions during high-volume production.

The screw and kneading configuration can be designed to provide controlled incorporation of high filler concentrations while maintaining stable material transport and mixing.
For large-scale production of filled compounds, this makes the ECK-200 a suitable platform for continuous industrial compounding.
Efficient Liquid Component Incorporation
Liquid additives can be introduced at selected points within the processing section.
The controlled kneading action helps incorporate liquid components into the polymer melt and distribute them throughout the formulation.
Depending on the application, liquid feeding may be used for:
- Plasticizers
- Processing aids
- Liquid additives
- Reactive components
- Lubricants
- Other formulation ingredients
The feeding location and injection configuration can be selected according to the material formulation and process requirements.
Temperature Control

The ECK-200 can be equipped with controlled cooling and heating zones to maintain stable processing temperatures throughout the barrel.
Efficient temperature management helps control:
- Polymer melt temperature
- Viscosity
- Residence conditions
- Additive stability
- Product consistency
- Thermal degradation
The processing temperature profile can be adapted according to the polymer and formulation.
For temperature-sensitive materials, controlled cooling is particularly important because excessive melt temperature can negatively affect color, viscosity, mechanical properties and long-term material performance.
Easy Cleaning and Maintenance
For large-scale compounding plants, cleaning and maintenance are important factors in overall production efficiency.
The ECK-200 is designed with accessibility to the processing components to facilitate inspection, cleaning and maintenance.
