Description
EXTRUTEX ECK-100 Co-Kneader Extruder
EXTRUTEX ECK-100 Co-Kneader Extruder – Professional Low-Shear Compounding System
The EXTRUTEX ECK-100 Co-Kneader Extruder is a high-capacity continuous compounding system engineered for manufacturers who require maximum production efficiency, exceptional mixing quality, low-shear processing and precise temperature control for demanding polymer formulations.
With a 100 mm screw diameter, 110 kW drive power, a maximum screw speed of 500 rpm and an output capacity of approximately 400–500 kg/h, the ECK-100 is designed for commercial-scale production of color masterbatch, engineering plastics, high-filler compounds, polyester compounds and specialty polymer formulations.
Unlike conventional extrusion systems that depend primarily on aggressive mechanical shear, the ECK-100 combines continuous screw rotation with reciprocating axial movement, creating an advanced kneading process that delivers outstanding material homogeneity while helping minimize thermal degradation and unnecessary mechanical stress.
The ECK-100 represents the ideal balance between high production capacity and premium compound quality, making it suitable for manufacturers producing consistent, high-value polymer compounds on an industrial scale.

The ECK-100 can be customized according to polymer type, formulation complexity, filler loading, additive package and downstream pelletizing requirements.
Advanced Co-Kneader Technology for Large-Scale Production
The ECK-100 utilizes the proven Co-Kneader principle, which differs significantly from conventional single-screw and co-rotating twin-screw extrusion systems.
Instead of relying solely on continuous screw rotation, the ECK-100 introduces an additional reciprocating axial movement that continuously changes the position of the screw relative to the stationary kneading pins inside the barrel.
This unique movement produces repeated folding, stretching and redistribution of the polymer throughout the processing chamber.
During operation, the material is continuously:
Divided
Folded
Recombined
Redistributed
Homogenized
Transported forward
This creates a highly efficient mixing environment while maintaining controlled mechanical and thermal conditions.
For industrial manufacturers processing hundreds of kilograms per hour, this combination of high throughput and controlled processing becomes a significant production advantage.
Rotating and Reciprocating Screw Technology
The specially engineered screw is the core component of the ECK-100.
During production, the screw performs two simultaneous movements.
The first is its continuous rotational movement, which transports material through the machine while generating the primary kneading action.
The second is the reciprocating axial movement, which repeatedly changes the interaction between the screw flights and the stationary kneading pins.
This creates additional transverse material movement that improves mixing efficiency throughout the entire processing chamber.
Instead of allowing material to follow a simple forward path, the ECK-100 continuously renews the material around the kneading elements, producing remarkably uniform compounds while maintaining controlled processing temperatures.
The 15 mm reciprocating stroke provides even greater material redistribution than smaller models, making the ECK-100 particularly effective for higher-capacity industrial production.
A Different Approach to Polymer Compounding
The ECK-100 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-100 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-100 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.
Low-Shear Processing for Heat-Sensitive Materials
One of the defining characteristics of the ECK-100 is its ability to provide efficient mixing while maintaining relatively low mechanical shear.
Many polymers, pigments and specialty additives are sensitive to excessive heat and mechanical stress.
Instead of exposing the formulation to unnecessarily aggressive processing conditions, the ECK-100 gradually softens and homogenizes the material through controlled kneading.
This processing principle can help provide:
Lower melt temperatures
Reduced thermal degradation
Improved viscosity retention
Better color stability
Improved additive performance
More consistent finished products
For manufacturers producing premium compounds where material quality is critical, this controlled processing environment can offer significant long-term production benefits.
Superior Dispersive and Distributive Mixing
The ECK-100 combines highly effective dispersive and distributive mixing throughout its processing chamber.
Dispersive mixing helps separate agglomerated pigments and filler particles.
Distributive mixing ensures these materials are evenly distributed throughout the polymer matrix.
The combination produces compounds with:
Uniform color
Consistent filler concentration
Stable additive distribution
Excellent homogeneity
Repeatable production quality
Improved downstream processing performance
This level of mixing quality is particularly valuable for manufacturers producing high-value masterbatch and engineering compounds.
High Degree of Self-Wiping
The reciprocating movement of the screw contributes to a high degree of self-wiping inside the processing chamber.
This helps reduce material buildup and stagnant zones that can affect product quality.
The self-wiping action contributes to:
Easier cleaning
Faster product changeovers
Reduced contamination
Improved production stability
Longer continuous operating periods
Simplified maintenance
For manufacturers producing multiple colors or formulations, reduced cleaning time can significantly improve production efficiency.
Excellent Dispersive and Distributive Mixing
The ECK-100 combines effective dispersive mixing and distributive mixing.
Dispersive mixing helps break down agglomerations of pigments, fillers and additives.
Distributive mixing ensures that these components are distributed consistently throughout the polymer matrix.
This combination is particularly valuable in masterbatch production and high-performance polymer compounds where even distribution of a relatively small amount of additive can have a significant effect on the final product.
The ECK-100 can therefore provide highly homogeneous compounds with:
- Uniform color
- Consistent filler concentration
- Stable additive distribution
- Consistent viscosity
- Improved material quality
- Repeatable production results
High Degree of Self-Wiping
The ECK-100 is particularly suitable for formulations requiring high concentrations of fillers and functional additives.
Typical materials include:
Calcium carbonate
Talc
Barium sulfate
Silica
Mica
Aluminum hydroxide
Magnesium hydroxide
Carbon black
Wood flour
Specialty mineral fillers
The controlled kneading action helps distribute these materials throughout the polymer matrix while maintaining excellent processing stability.
With a production capacity of 400–500 kg/h, the ECK-100 is well suited for commercial production of high-filler compounds.
Efficient Liquid Additive Incorporation
The ECK-100 can also process formulations containing liquid components.
Examples include:
Plasticizers
Processing oils
Waxes
Coupling agents
Liquid stabilizers
Processing aids
Specialty additives
The repeated folding and redistribution of material inside the kneading chamber helps ensure efficient incorporation of liquid ingredients throughout the polymer matrix.
This makes the ECK-100 a versatile solution for complex formulations containing both solid and liquid components.
High Filler Loading Capability
The ECK-100 is suitable for formulations containing significant quantities of mineral and functional fillers.
Depending on the polymer and formulation, 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 processing mechanism provides effective filler incorporation while maintaining controlled processing conditions.
The larger 100 mm screw diameter and 400-500 kg/h output range make the ECK-70 suitable for industrial production where higher throughput is required.
High Degree of Self-Wiping
The reciprocating movement of the screw contributes to a high degree of self-wiping inside the processing chamber.
The continuous interaction between the screw flights and stationary kneading pins helps minimize stagnant material zones and unwanted accumulation.
This is particularly useful when processing different formulations or colors on the same machine.
A cleaner processing chamber can help with:
- Faster product changeover
- Reduced contamination
- Easier cleaning
- More stable processing
- Reduced material residence
- Easier maintenance
For masterbatch manufacturers producing multiple colors and formulations, this feature can be especially valuable.
Efficient Liquid Component Incorporation
The ECK-100 can also be configured for formulations containing liquid additives.
Examples include:
- Plasticizers
- Processing oils
- Waxes
- Liquid coupling agents
- Processing aids
- Liquid stabilizers
- Specialty additives
The continuous folding and redistribution of material inside the kneading chamber helps incorporate liquid components into the polymer matrix.
This makes the ECK-100 a flexible platform for formulations that combine polymers, powders, fillers and liquid additives.
Precise Temperature Control
Temperature management is one of the most important aspects of industrial polymer compounding.
The ECK-100 can be equipped with water cooling for both the barrel and screw, allowing processing temperatures to be controlled according to the formulation.
The combination of low-shear processing and efficient cooling helps reduce unnecessary heat generation while maintaining stable processing conditions.
Benefits include:
Stable melt temperature
Reduced thermal degradation
Better viscosity stability
Improved color consistency
Reliable additive performance
Consistent production quality
The principle remains simple: achieve excellent mixing while minimizing unnecessary heat.

Instead of relying solely on continuous screw rotation, the ECK-100 introduces an additional reciprocating axial movement that continuously changes the position of the screw relative to the stationary kneading pins inside the barrel.
This unique movement produces repeated folding, stretching and redistribution of the polymer throughout the processing chamber.
During operation, the material is continuously:
Divided
Folded
Recombined
Redistributed
Homogenized
Transported forward
This creates a highly efficient mixing environment while maintaining controlled mechanical and thermal conditions.
For industrial manufacturers processing hundreds of kilograms per hour, this combination of high throughput and controlled processing becomes a significant production advantage.
Rotating and Reciprocating Screw Technology
The specially engineered screw is the core component of the ECK-100.
During production, the screw performs two simultaneous movements.
The first is its continuous rotational movement, which transports material through the machine while generating the primary kneading action.
The second is the reciprocating axial movement, which repeatedly changes the interaction between the screw flights and the stationary kneading pins.
This creates additional transverse material movement that improves mixing efficiency throughout the entire processing chamber.
Instead of allowing material to follow a simple forward path, the ECK-100 continuously renews the material around the kneading elements, producing remarkably uniform compounds while maintaining controlled processing temperatures.
The 15 mm reciprocating stroke provides even greater material redistribution than smaller models, making the ECK-100 particularly effective for higher-capacity industrial production.
A Different Approach to Polymer Compounding
The ECK-100 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-100 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-100 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.
Low-Shear Processing for Heat-Sensitive Materials
One of the defining characteristics of the ECK-100 is its ability to provide efficient mixing while maintaining relatively low mechanical shear.
Many polymers, pigments and specialty additives are sensitive to excessive heat and mechanical stress.
Instead of exposing the formulation to unnecessarily aggressive processing conditions, the ECK-100 gradually softens and homogenizes the material through controlled kneading.
This processing principle can help provide:
Lower melt temperatures
Reduced thermal degradation
Improved viscosity retention
Better color stability
Improved additive performance
More consistent finished products
For manufacturers producing premium compounds where material quality is critical, this controlled processing environment can offer significant long-term production benefits.
Superior Dispersive and Distributive Mixing
The ECK-100 combines highly effective dispersive and distributive mixing throughout its processing chamber.
Dispersive mixing helps separate agglomerated pigments and filler particles.
Distributive mixing ensures these materials are evenly distributed throughout the polymer matrix.
The combination produces compounds with:
Uniform color
Consistent filler concentration
Stable additive distribution
Excellent homogeneity
Repeatable production quality
Improved downstream processing performance
This level of mixing quality is particularly valuable for manufacturers producing high-value masterbatch and engineering compounds.
High Degree of Self-Wiping
The reciprocating movement of the screw contributes to a high degree of self-wiping inside the processing chamber.
This helps reduce material buildup and stagnant zones that can affect product quality.
The self-wiping action contributes to:
Easier cleaning
Faster product changeovers
Reduced contamination
Improved production stability
Longer continuous operating periods
Simplified maintenance
For manufacturers producing multiple colors or formulations, reduced cleaning time can significantly improve production efficiency.
Excellent Dispersive and Distributive Mixing
The ECK-100 combines effective dispersive mixing and distributive mixing.
Dispersive mixing helps break down agglomerations of pigments, fillers and additives.
Distributive mixing ensures that these components are distributed consistently throughout the polymer matrix.
This combination is particularly valuable in masterbatch production and high-performance polymer compounds where even distribution of a relatively small amount of additive can have a significant effect on the final product.
The ECK-100 can therefore provide highly homogeneous compounds with:
- Uniform color
- Consistent filler concentration
- Stable additive distribution
- Consistent viscosity
- Improved material quality
- Repeatable production results
High Degree of Self-Wiping
The ECK-100 is particularly suitable for formulations requiring high concentrations of fillers and functional additives.
Typical materials include:
Calcium carbonate
Talc
Barium sulfate
Silica
Mica
Aluminum hydroxide
Magnesium hydroxide
Carbon black
Wood flour
Specialty mineral fillers
The controlled kneading action helps distribute these materials throughout the polymer matrix while maintaining excellent processing stability.
With a production capacity of 400–500 kg/h, the ECK-100 is well suited for commercial production of high-filler compounds.
Efficient Liquid Additive Incorporation
The ECK-100 can also process formulations containing liquid components.
Examples include:
Plasticizers
Processing oils
Waxes
Coupling agents
Liquid stabilizers
Processing aids
Specialty additives
The repeated folding and redistribution of material inside the kneading chamber helps ensure efficient incorporation of liquid ingredients throughout the polymer matrix.
This makes the ECK-100 a versatile solution for complex formulations containing both solid and liquid components.
High Filler Loading Capability
The ECK-100 is suitable for formulations containing significant quantities of mineral and functional fillers.
Depending on the polymer and formulation, 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 processing mechanism provides effective filler incorporation while maintaining controlled processing conditions.
The larger 100 mm screw diameter and 400-500 kg/h output range make the ECK-70 suitable for industrial production where higher throughput is required.
High Degree of Self-Wiping
The reciprocating movement of the screw contributes to a high degree of self-wiping inside the processing chamber.
The continuous interaction between the screw flights and stationary kneading pins helps minimize stagnant material zones and unwanted accumulation.
This is particularly useful when processing different formulations or colors on the same machine.
A cleaner processing chamber can help with:
- Faster product changeover
- Reduced contamination
- Easier cleaning
- More stable processing
- Reduced material residence
- Easier maintenance
For masterbatch manufacturers producing multiple colors and formulations, this feature can be especially valuable.
Efficient Liquid Component Incorporation
The ECK-100 can also be configured for formulations containing liquid additives.
Examples include:
- Plasticizers
- Processing oils
- Waxes
- Liquid coupling agents
- Processing aids
- Liquid stabilizers
- Specialty additives
The continuous folding and redistribution of material inside the kneading chamber helps incorporate liquid components into the polymer matrix.
This makes the ECK-100 a flexible platform for formulations that combine polymers, powders, fillers and liquid additives.
Precise Temperature Control
Temperature management is one of the most important aspects of industrial polymer compounding.
The ECK-100 can be equipped with water cooling for both the barrel and screw, allowing processing temperatures to be controlled according to the formulation.
The combination of low-shear processing and efficient cooling helps reduce unnecessary heat generation while maintaining stable processing conditions.
Benefits include:
Stable melt temperature
Reduced thermal degradation
Better viscosity stability
Improved color consistency
Reliable additive performance
Consistent production quality
The principle remains simple: achieve excellent mixing while minimizing unnecessary heat.
