Description
EXTRUTEX ECK-140 Co-Kneader Extruder
EXTRUTEX ECK-140 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.

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.
A Different Approach to Polymer Compounding
The ECK-140 is based on a different compounding philosophy from traditional extrusion technology.
A conventional extruder primarily transports material forward through a rotating screw. The ECK Co-Kneader introduces another dimension to the process: the screw also moves backwards and forwards along its axis.
Special kneading flights on the screw interact with stationary kneading pins installed inside the barrel. During operation, the moving screw flights repeatedly pass the fixed pins, creating a controlled combination of longitudinal and transverse material movement.
The material is continuously:
- Divided
- Folded
- Stretched
- Redistributed
- Recombined
- Homogenized
This creates highly efficient mixing without requiring extremely aggressive mechanical shear.
Rotating and Reciprocating Screw Technology
The heart of the ECK-100 is its specially engineered reciprocating screw.
During operation, the screw performs two simultaneous movements:
Rotational movement provides continuous material transport and kneading.
Reciprocating movement changes the position of the kneading flights relative to the stationary pins and creates additional transverse movement of the polymer.
This combination significantly improves the mixing action inside the processing chamber.
Instead of allowing material to travel through a simple forward-flow path, the ECK-140 continuously renews the material around the kneading elements.
This helps produce a highly uniform compound while maintaining controlled processing conditions.
Three-Row Stationary Kneading Pin System
The ECK-140 incorporates a specially designed stationary kneading pin system that works together with the moving screw flights to create highly efficient mixing.
As the screw rotates and reciprocates, the material repeatedly encounters the kneading pins, producing both distributive and dispersive mixing.
The system helps achieve:
Excellent pigment dispersion
Uniform filler distribution
Effective additive incorporation
Improved polymer homogenization
Stable melt quality
Reduced stagnant material zones
Consistent production quality
The geometry of both the screw and kneading pins can be optimized according to the polymer formulation and production requirements.
Stationary Kneading Pin System
The ECK-140 processing chamber incorporates specially engineered stationary kneading pins.
The pins interact with the moving screw flights during the rotational and reciprocating movements of the screw.
This interaction creates controlled material deformation and redistribution throughout the processing chamber.
The kneading system contributes to:
- Excellent pigment dispersion
- Uniform filler distribution
- Effective additive incorporation
- Improved polymer homogenization
- Consistent melt quality
- Reduced stagnant areas
- Stable continuous processing
The processing configuration can be selected according to the polymer and formulation requirements.
Low-Shear Polymer Processing
One of the main advantages of the ECK Co-Kneader technology is its ability to provide effective mixing without relying exclusively on extremely aggressive mechanical shear.
This is particularly important for polymers and additives that can be affected by excessive mechanical energy or high temperatures.
The ECK-140 provides controlled kneading action that helps distribute and homogenize the material while reducing unnecessary processing stress.
Potential benefits include:
- Controlled melt temperature
- Reduced thermal degradation
- Improved viscosity retention
- Better color stability
- Improved additive performance
- Consistent compound quality
- Stable long-term production
The large 140 mm processing diameter allows these processing principles to be applied at a production capacity of approximately 800–1000 kg/h.
Excellent Dispersive and Distributive Mixing
The ECK-140 combines dispersive mixing and distributive mixing to produce highly homogeneous polymer compounds.
Dispersive mixing helps break down agglomerated pigment, filler and additive particles.
Distributive mixing then distributes these components throughout the polymer matrix.
This combination is particularly important for industrial masterbatch and specialty compound production, where small variations in additive distribution can affect the final product.
The ECK-140 can provide:
- Uniform color
- Consistent filler concentration
- Stable additive distribution
- Excellent material homogeneity
- Repeatable compound quality
- Stable downstream processing
High Degree of Self-Wiping
The reciprocating screw movement contributes to a high degree of self-wiping inside the processing chamber.
The interaction between the screw flights and stationary kneading pins helps minimize material accumulation and stagnant zones.
This can be particularly beneficial in high-volume production where long operating periods and reliable changeovers are important.
The self-wiping action can help provide:
- Easier cleaning
- Faster product changeover
- Reduced contamination
- More stable production
- Reduced unwanted material residence
- Simplified maintenance
For manufacturers producing different colors or formulations, these characteristics can help improve production efficiency.
High Filler Loading Capability

- Other mineral and functional fillers
The Co-Kneader mechanism provides effective filler incorporation and distribution throughout the polymer matrix.
With an output capacity of 800–1000 kg/h, the ECK-140 is designed for manufacturers requiring high-volume production of filled polymer compounds.
Efficient Liquid Additive Incorporation
The ECK-140 can also be configured for formulations containing liquid components.
Potential liquid ingredients include:
- Plasticizers
- Processing oils
- Waxes
- Coupling agents
- Processing aids
- Liquid stabilizers
- Specialty additives
The repeated folding and redistribution of material inside the kneading chamber helps incorporate liquid components into the polymer matrix.
This makes the ECK-140 suitable for complex formulations containing combinations of polymer, powders, fillers and liquid additives.
Precise Temperature Control
Temperature management becomes particularly important when processing large quantities of polymer.
The ECK-140 can be equipped with an appropriate cooling system for the barrel and screw according to the application.
The controlled Co-Kneader processing principle helps minimize unnecessary mechanical heat generation, while the cooling system provides additional control over the processing temperature.
Maintaining an appropriate temperature can help provide:
- Stable melt conditions

EXTRUTEX ECK-140 Co-Kneader Extruder
EXTRUTEX ECK-140 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.
ECK-140 Technical Specifications
| 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 |
| Output Capacity | 800–1000 kg/h |
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.
A Different Approach to Polymer Compounding
The ECK-140 is based on a different compounding philosophy from traditional extrusion technology.
A conventional extruder primarily transports material forward through a rotating screw. The ECK Co-Kneader introduces another dimension to the process: the screw also moves backwards and forwards along its axis.
Special kneading flights on the screw interact with stationary kneading pins installed inside the barrel. During operation, the moving screw flights repeatedly pass the fixed pins, creating a controlled combination of longitudinal and transverse material movement.
The material is continuously:
- Divided
- Folded
- Stretched
- Redistributed
- Recombined
- Homogenized
This creates highly efficient mixing without requiring extremely aggressive mechanical shear.
Rotating and Reciprocating Screw Technology
The heart of the ECK-100 is its specially engineered reciprocating screw.
During operation, the screw performs two simultaneous movements:
Rotational movement provides continuous material transport and kneading.
Reciprocating movement changes the position of the kneading flights relative to the stationary pins and creates additional transverse movement of the polymer.
This combination significantly improves the mixing action inside the processing chamber.
Instead of allowing material to travel through a simple forward-flow path, the ECK-140 continuously renews the material around the kneading elements.
This helps produce a highly uniform compound while maintaining controlled processing conditions.
Three-Row Stationary Kneading Pin System
The ECK-140 incorporates a specially designed stationary kneading pin system that works together with the moving screw flights to create highly efficient mixing.
As the screw rotates and reciprocates, the material repeatedly encounters the kneading pins, producing both distributive and dispersive mixing.
The system helps achieve:
Excellent pigment dispersion
Uniform filler distribution
Effective additive incorporation
Improved polymer homogenization
Stable melt quality
Reduced stagnant material zones
Consistent production quality
The geometry of both the screw and kneading pins can be optimized according to the polymer formulation and production requirements.
Stationary Kneading Pin System
The ECK-140 processing chamber incorporates specially engineered stationary kneading pins.
The pins interact with the moving screw flights during the rotational and reciprocating movements of the screw.
This interaction creates controlled material deformation and redistribution throughout the processing chamber.
The kneading system contributes to:
- Excellent pigment dispersion
- Uniform filler distribution
- Effective additive incorporation
- Improved polymer homogenization
- Consistent melt quality
- Reduced stagnant areas
- Stable continuous processing
The processing configuration can be selected according to the polymer and formulation requirements.
Low-Shear Polymer Processing
One of the main advantages of the ECK Co-Kneader technology is its ability to provide effective mixing without relying exclusively on extremely aggressive mechanical shear.
This is particularly important for polymers and additives that can be affected by excessive mechanical energy or high temperatures.
The ECK-140 provides controlled kneading action that helps distribute and homogenize the material while reducing unnecessary processing stress.
Potential benefits include:
- Controlled melt temperature
- Reduced thermal degradation
- Improved viscosity retention
- Better color stability
- Improved additive performance
- Consistent compound quality
- Stable long-term production
The large 140 mm processing diameter allows these processing principles to be applied at a production capacity of approximately 800–1000 kg/h.
Excellent Dispersive and Distributive Mixing
The ECK-140 combines dispersive mixing and distributive mixing to produce highly homogeneous polymer compounds.
Dispersive mixing helps break down agglomerated pigment, filler and additive particles.
Distributive mixing then distributes these components throughout the polymer matrix.
This combination is particularly important for industrial masterbatch and specialty compound production, where small variations in additive distribution can affect the final product.
The ECK-140 can provide:
- Uniform color
- Consistent filler concentration
- Stable additive distribution
- Excellent material homogeneity
- Repeatable compound quality
- Stable downstream processing
High Degree of Self-Wiping
The reciprocating screw movement contributes to a high degree of self-wiping inside the processing chamber.
The interaction between the screw flights and stationary kneading pins helps minimize material accumulation and stagnant zones.
This can be particularly beneficial in high-volume production where long operating periods and reliable changeovers are important.
The self-wiping action can help provide:
- Easier cleaning
- Faster product changeover
- Reduced contamination
- More stable production
- Reduced unwanted material residence
- Simplified maintenance
For manufacturers producing different colors or formulations, these characteristics can help improve production efficiency.
High Filler Loading Capability
The ECK-140 is suitable for high-volume production of polymer compounds containing substantial quantities of mineral and functional fillers.
Potential fillers include:
- Calcium carbonate
- Talc
- Barium sulfate
- Silica
- Mica
- Aluminum hydroxide
- Magnesium hydroxide
- Carbon black
- Wood flour
- Other mineral and functional fillers
The Co-Kneader mechanism provides effective filler incorporation and distribution throughout the polymer matrix.
With an output capacity of 800–1000 kg/h, the ECK-140 is designed for manufacturers requiring high-volume production of filled polymer compounds.
Efficient Liquid Additive Incorporation
The ECK-140 can also be configured for formulations containing liquid components.
Potential liquid ingredients include:
- Plasticizers
- Processing oils
- Waxes
- Coupling agents
- Processing aids
- Liquid stabilizers
- Specialty additives
The repeated folding and redistribution of material inside the kneading chamber helps incorporate liquid components into the polymer matrix.
This makes the ECK-140 suitable for complex formulations containing combinations of polymer, powders, fillers and liquid additives.
Precise Temperature Control
Temperature management becomes particularly important when processing large quantities of polymer.
The ECK-140 can be equipped with an appropriate cooling system for the barrel and screw according to the application.
The controlled Co-Kneader processing principle helps minimize unnecessary mechanical heat generation, while the cooling system provides additional control over the processing temperature.
Maintaining an appropriate temperature can help provide:
- Stable melt conditions
- Reduced thermal degradation
- Better viscosity stability
- Improved color consistency
- Reliable additive performance
