EXTRUTEX ECK-45 Co-Kneader Extruder
Description
EXTRUTEX ECK-45 Co-Kneader Extruder
EXTRUTEX ECK-45 Co-Kneader Extruder – Professional Low-Shear Compounding System
The EXTRUTEX ECK-45 Co-Kneader Extruder is a professional continuous compounding system designed for demanding polymer processing applications where excellent mixing, low shear, controlled temperature and high product consistency are essential.
With a 45 mm screw diameter, 22 kW drive power, maximum screw speed of 500 rpm and an output capacity of approximately 40–60 kg/h, the ECK-45 provides a compact and highly efficient solution for pilot production, specialty compounds, masterbatch production, research and development, and smaller industrial production requirements.
Unlike conventional single-screw or co-rotating twin-screw extruders, the ECK-45 combines continuous screw rotation with reciprocating axial movement. This unique mechanism allows the polymer and additives to be kneaded and redistributed efficiently while minimizing unnecessary shear and excessive melt temperature.
The result is a highly homogeneous compound with excellent dispersion and controlled thermal history.
ECK-45 Technical Specifications
| Parameter | ECK-45 |
|---|---|
| Model | ECK-45 |
| Screw Diameter | 45 mm |
| L/D Ratio | 10–25 |
| Reciprocating Stroke | 6.75 mm |
| Drive Power | 22 kW |
| Maximum Screw Speed | 500 rpm |
| Output Capacity | 40–60 kg/h |
The ECK-45 can be configured according to the material formulation, additives, filler loading, required output and downstream process.
A Different Approach to Polymer Compounding
The ECK-45 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-45 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-45 continuously renews the material around the kneading elements.
This helps produce a highly uniform compound while maintaining controlled processing conditions.
Three Rows of Stationary Kneading Pins
One of the most important features of the ECK technology is the interaction between the moving screw flights and stationary kneading pins.
The kneading pins are mounted into the barrel and extend into the processing chamber. As the screw rotates and reciprocates, its kneading flights repeatedly interact with these fixed pins.
This creates a series of controlled mixing zones throughout the machine.
The interaction provides:
- Excellent distributive mixing
- Effective dispersive mixing
- Uniform filler distribution
- Improved pigment dispersion
- Efficient additive incorporation
- Reduced stagnant areas
- Consistent compound quality
The unique movement also helps maintain continuous material circulation inside the kneading chamber.
Extremely Low-Shear Processing
One of the main advantages of the ECK-45 Co-Kneader is its ability to provide efficient mixing while maintaining relatively low shear.
This is particularly important for materials that can be damaged by excessive mechanical energy or high processing temperatures.
Heat-sensitive polymers, pigments, additives and specialty fillers may lose their desired properties when exposed to excessive thermal and mechanical stress.
The ECK-45 is designed to process materials as they gradually soften and become homogenized rather than subjecting them to unnecessarily severe processing conditions.
Potential benefits include:
- Lower melt temperature
- Reduced thermal degradation
- Better viscosity retention
- Improved color stability
- Reduced additive degradation
- Improved final product consistency
For specialty compounds where material quality is more important than simply maximizing mechanical shear, this processing principle can provide a significant advantage.
Highly Homogeneous Mixing
The ECK-45 provides both dispersive and distributive mixing.
Dispersive mixing helps break down and distribute agglomerated additives, pigments and filler particles.
Distributive mixing ensures that these components are distributed uniformly throughout the polymer matrix.
The combination is particularly important in masterbatch and specialty compound production, where even small variations in pigment or additive distribution can affect the final product.
The ECK-45 can therefore be used to produce compounds with:
- Uniform color
- Consistent filler distribution
- Stable viscosity
- Consistent additive concentration
- Excellent material homogeneity
- Repeatable production quality
High Degree of Self-Wiping
Another important characteristic of the ECK-45 is its high degree of self-wiping.
The continuous movement of the screw and its interaction with the stationary kneading elements helps minimize material accumulation inside the processing chamber.
This reduces the possibility of stagnant areas and unwanted material buildup.
The result is:
- Cleaner processing
- Reduced contamination
- Easier product changeover
- Reduced material residence in dead zones
- Improved operational stability
- Easier maintenance
This feature is particularly valuable for manufacturers producing different formulations or colors on the same machine.
High Filler Loading Capability
The ECK-45 is also suitable for formulations containing high concentrations of fillers and additives.
Depending on the polymer and formulation, applications can include:
- Calcium carbonate
- Talc
- Barium sulfate
- Silica
- Mica
- Aluminum hydroxide
- Magnesium hydroxide
- Carbon black
- Wood flour
- Other mineral fillers
The controlled kneading action helps distribute high concentrations of filler throughout the polymer matrix while avoiding unnecessarily aggressive mechanical treatment.
This makes the ECK-45 suitable for specialty filler compounds where high loading and good dispersion must be achieved simultaneously.
Efficient Processing of Liquid Components
The ECK-45 can also be configured for formulations requiring liquid additives.
Liquid components may include:
- Plasticizers
- Processing oils
- Waxes
- 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 efficiently.
This makes the ECK-45 a flexible platform for formulations containing both solid and liquid ingredients.
Precise Temperature Control
Temperature control is one of the most important factors in polymer compounding.
The ECK-45 uses a water cooling system for the barrel and screw to help maintain controlled processing temperatures.
Because the Co-Kneader operates with relatively low shear, less unnecessary heat is generated compared with highly aggressive mixing processes.
The cooling system allows the processing temperature to be controlled accurately according to the characteristics of the polymer and formulation.
This can help provide:
- Stable processing temperature
- Lower melt temperature
- Reduced thermal degradation
- Better viscosity stability
- Improved color consistency
- Better additive performance
- More repeatable production
The principle is simple: mix efficiently while avoiding unnecessary heat.
Stable Pressure and Continuous Processing
The ECK-45 can be equipped with an appropriate end section and breechblock arrangement to maintain stable pressure during material discharge.
Stable pressure is important for consistent extrusion and reliable downstream processing.
Depending on the application, the ECK-45 can be integrated with suitable:
- Melt filtration
- Strand dies
- Pelletizing systems
- Water cooling
- Strand cooling
- Cutting systems
- Automatic conveying
- Packaging systems
This allows EXTRUTEX to provide the ECK-45 as part of a complete compounding solution rather than simply as an individual extruder.
Easy Barrel Opening and Cleaning
Industrial compounding equipment must be easy to maintain.
The ECK-45 is designed with an axially opening barrel, providing convenient access to the internal processing area.
Operators can access the screw and kneading chamber for:
- Inspection
- Cleaning
- Maintenance
- Component replacement
- Product changeover
- Wear inspection
Easy access reduces maintenance time and makes routine servicing more practical.
Modular Screw, Barrel and Pin Maintenance
The ECK-45 is designed with replaceable processing components.
Depending on the machine configuration and application, individual components such as the screw, barrel sections and kneading pins can be serviced or replaced.
This modular approach helps reduce maintenance costs and allows the machine to be maintained according to actual wear conditions.
It also provides greater flexibility when the machine is used for different formulations.
Applications of the ECK-45
The compact ECK-45 is suitable for a broad range of polymer compounding applications.
Color Masterbatch
The ECK-45 is particularly suitable for color masterbatch applications requiring excellent pigment dispersion and consistent color quality.
Its low-shear processing characteristics can help reduce unnecessary thermal stress while maintaining effective pigment distribution.

High-Filler Compounds
The machine is suitable for development and production of high-filler formulations where filler loading and dispersion are important.
Elastomers and Specialty Materials
The ECK-45 can also be configured for selected elastomer, thermoplastic elastomer and specialty polymer applications.

- Develop new formulations
- Test pigments
- Evaluate additives
- Optimize filler concentrations

EXTRUTEX ECK-45 Co-Kneader Extruder
EXTRUTEX ECK-45 Co-Kneader Extruder – Professional Low-Shear Compounding System
The EXTRUTEX ECK-45 Co-Kneader Extruder is a professional continuous compounding system designed for demanding polymer processing applications where excellent mixing, low shear, controlled temperature and high product consistency are essential.
With a 45 mm screw diameter, 22 kW drive power, maximum screw speed of 500 rpm and an output capacity of approximately 40–60 kg/h, the ECK-45 provides a compact and highly efficient solution for pilot production, specialty compounds, masterbatch production, research and development, and smaller industrial production requirements.
Unlike conventional single-screw or co-rotating twin-screw extruders, the ECK-45 combines continuous screw rotation with reciprocating axial movement. This unique mechanism allows the polymer and additives to be kneaded and redistributed efficiently while minimizing unnecessary shear and excessive melt temperature.
The result is a highly homogeneous compound with excellent dispersion and controlled thermal history.
ECK-45 Technical Specifications
| Parameter | ECK-45 |
|---|---|
| Model | ECK-45 |
| Screw Diameter | 45 mm |
| L/D Ratio | 10–25 |
| Reciprocating Stroke | 6.75 mm |
| Drive Power | 22 kW |
| Maximum Screw Speed | 500 rpm |
| Output Capacity | 40–60 kg/h |
The ECK-45 can be configured according to the material formulation, additives, filler loading, required output and downstream process.
A Different Approach to Polymer Compounding
The ECK-45 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-45 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-45 continuously renews the material around the kneading elements.
This helps produce a highly uniform compound while maintaining controlled processing conditions.
Three Rows of Stationary Kneading Pins
One of the most important features of the ECK technology is the interaction between the moving screw flights and stationary kneading pins.
The kneading pins are mounted into the barrel and extend into the processing chamber. As the screw rotates and reciprocates, its kneading flights repeatedly interact with these fixed pins.
This creates a series of controlled mixing zones throughout the machine.
The interaction provides:
- Excellent distributive mixing
- Effective dispersive mixing
- Uniform filler distribution
- Improved pigment dispersion
- Efficient additive incorporation
- Reduced stagnant areas
- Consistent compound quality
The unique movement also helps maintain continuous material circulation inside the kneading chamber.
Extremely Low-Shear Processing
One of the main advantages of the ECK-45 Co-Kneader is its ability to provide efficient mixing while maintaining relatively low shear.
This is particularly important for materials that can be damaged by excessive mechanical energy or high processing temperatures.
Heat-sensitive polymers, pigments, additives and specialty fillers may lose their desired properties when exposed to excessive thermal and mechanical stress.
The ECK-45 is designed to process materials as they gradually soften and become homogenized rather than subjecting them to unnecessarily severe processing conditions.
Potential benefits include:
- Lower melt temperature
- Reduced thermal degradation
- Better viscosity retention
- Improved color stability
- Reduced additive degradation
- Improved final product consistency
For specialty compounds where material quality is more important than simply maximizing mechanical shear, this processing principle can provide a significant advantage.
Highly Homogeneous Mixing
The ECK-45 provides both dispersive and distributive mixing.
Dispersive mixing helps break down and distribute agglomerated additives, pigments and filler particles.
Distributive mixing ensures that these components are distributed uniformly throughout the polymer matrix.
The combination is particularly important in masterbatch and specialty compound production, where even small variations in pigment or additive distribution can affect the final product.
The ECK-45 can therefore be used to produce compounds with:
- Uniform color
- Consistent filler distribution
- Stable viscosity
- Consistent additive concentration
- Excellent material homogeneity
- Repeatable production quality
High Degree of Self-Wiping
Another important characteristic of the ECK-45 is its high degree of self-wiping.
The continuous movement of the screw and its interaction with the stationary kneading elements helps minimize material accumulation inside the processing chamber.
This reduces the possibility of stagnant areas and unwanted material buildup.
The result is:
- Cleaner processing
- Reduced contamination
- Easier product changeover
- Reduced material residence in dead zones
- Improved operational stability
- Easier maintenance
This feature is particularly valuable for manufacturers producing different formulations or colors on the same machine.
High Filler Loading Capability
The ECK-45 is also suitable for formulations containing high concentrations of fillers and additives.
Depending on the polymer and formulation, applications can include:
- Calcium carbonate
- Talc
- Barium sulfate
- Silica
- Mica
- Aluminum hydroxide
- Magnesium hydroxide
- Carbon black
- Wood flour
- Other mineral fillers
The controlled kneading action helps distribute high concentrations of filler throughout the polymer matrix while avoiding unnecessarily aggressive mechanical treatment.
This makes the ECK-45 suitable for specialty filler compounds where high loading and good dispersion must be achieved simultaneously.
Efficient Processing of Liquid Components
The ECK-45 can also be configured for formulations requiring liquid additives.
Liquid components may include:
- Plasticizers
- Processing oils
- Waxes
- 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 efficiently.
This makes the ECK-45 a flexible platform for formulations containing both solid and liquid ingredients.
Precise Temperature Control
Temperature control is one of the most important factors in polymer compounding.
The ECK-45 uses a water cooling system for the barrel and screw to help maintain controlled processing temperatures.
Because the Co-Kneader operates with relatively low shear, less unnecessary heat is generated compared with highly aggressive mixing processes.
The cooling system allows the processing temperature to be controlled accurately according to the characteristics of the polymer and formulation.
This can help provide:
- Stable processing temperature
- Lower melt temperature
- Reduced thermal degradation
- Better viscosity stability
- Improved color consistency
- Better additive performance
- More repeatable production
The principle is simple: mix efficiently while avoiding unnecessary heat.
Stable Pressure and Continuous Processing
The ECK-45 can be equipped with an appropriate end section and breechblock arrangement to maintain stable pressure during material discharge.
Stable pressure is important for consistent extrusion and reliable downstream processing.
Depending on the application, the ECK-45 can be integrated with suitable:
- Melt filtration
- Strand dies
- Pelletizing systems
- Water cooling
- Strand cooling
- Cutting systems
- Automatic conveying
- Packaging systems
This allows EXTRUTEX to provide the ECK-45 as part of a complete compounding solution rather than simply as an individual extruder.
Easy Barrel Opening and Cleaning
Industrial compounding equipment must be easy to maintain.
The ECK-45 is designed with an axially opening barrel, providing convenient access to the internal processing area.
Operators can access the screw and kneading chamber for:
- Inspection
- Cleaning
- Maintenance
- Component replacement
- Product changeover
- Wear inspection
Easy access reduces maintenance time and makes routine servicing more practical.
Modular Screw, Barrel and Pin Maintenance
The ECK-45 is designed with replaceable processing components.
Depending on the machine configuration and application, individual components such as the screw, barrel sections and kneading pins can be serviced or replaced.
This modular approach helps reduce maintenance costs and allows the machine to be maintained according to actual wear conditions.
It also provides greater flexibility when the machine is used for different formulations.
Applications of the ECK-45
The compact ECK-45 is suitable for a broad range of polymer compounding applications.
Color Masterbatch
The ECK-45 is particularly suitable for color masterbatch applications requiring excellent pigment dispersion and consistent color quality.
Its low-shear processing characteristics can help reduce unnecessary thermal stress while maintaining effective pigment distribution.
Polyester Masterbatch
Polyester masterbatch is one of the important application areas for Co-Kneader technology.
The ECK-45 can be used for development, pilot production and specialty polyester masterbatch formulations where viscosity, dispersion and temperature control are important.
Engineering Plastics
Depending on formulation and processing requirements, the ECK-45 can be applied to engineering polymers such as:
- PA
- PET
- PBT
- PC
- ABS
- ASA
- PPO
- Other specialty polymers
PVC Compounds
The ECK-45 can also be considered for selected PVC formulations where controlled temperature and gentle processing are important.
Flame-Retardant Compounds
Flame-retardant formulations often contain significant amounts of additives and mineral components.
The ECK-45 provides effective incorporation and distribution while maintaining controlled processing conditions.
High-Filler Compounds
The machine is suitable for development and production of high-filler formulations where filler loading and dispersion are important.
Elastomers and Specialty Materials
The ECK-45 can also be configured for selected elastomer, thermoplastic elastomer and specialty polymer applications.
ECK-45 for Masterbatch Development
The compact size of the ECK-45 makes it particularly useful for companies developing new masterbatch and polymer formulations.
Manufacturers can use the machine to:
- Develop new formulations
- Test pigments
- Evaluate additives
- Optimize filler concentrations
