Extrusion technology
The core concept behind extrusion technology consists of continuous pressing of the liquefied plastic through a shaping opening in order to create the desired profile shape. High material output and very low downtimes are important keys to success in this process technology. Extruding the material with a power of up to 800 kW requires powerful drive controllers, which KEB has been offering for over 20 years in the field of plastics technology. Paired with a high-quality control system and a powerful motor, users acquire a comprehensive system solution for use in extruders.
Getting plastic into shape
Profile extrusion
Whether they are using extruder software, frequency inverters or (water-cooled) motors perfectly tuned to KEB’s control technology, in the area of profile extrusion, users benefit from KEB’s extensive portfolio of products and solutions. As a result, extruder applications are easy to implement – individually adapted to your machines. Find out more about extruder solutions
Flat film and blown film
Day after day, blown film units have to carry out tasks such as ensuring safe operation of the main drive, and driving fans or winders. With suitable technical features, KEB’s system solutions ensure that you always get the most out of your machine. What we offer for blown film units
Blow-moulding machines
Blow-moulding is a multi-stage process. This places various demands on the drive technology. KEB meets these demands, for example, with high-performance drive controllers, and increases the machine’s energy efficiency with its innovative approaches. Learn more about our system solution
Downstream equipment / Handling systems
In search of high-performance solutions for downstream equipment? KEB provides the answer with its compact servo inverters. As a system supplier, KEB also provides controls that are easy to put into operation – and all the components work together so you get the greatest possible benefit.

Extruder solutions
Extruders
KEB offers a comprehensive project framework for the complete automation of extruder systems. This makes it possible to operate both the extruder itself as well as any downstream equipment such as the melt pump. From newly developed extruder software – which is perfectly tuned to KEB’s control technology – via the drive controller, to the motors. KEB’s portfolio enables users to create a 360-degree system solution for machines. In doing so, the extruder solution can be optimally adapted to the requirements of the customer’s machinery in terms of both software and hardware.
Blow film units
From the main drive and fan to the hood and winder, KEB offers a system solution from one source for blown film units. With outstanding torque accuracy (+/- 3 percent) and high availability, KEB ensures that you get the most out of your machines. Technical features in the system solution enable effortless bridging of voltage dips and safe operation of the unit is ensured at all times with the Safety Modules. Suitable geared motors for downstream equipment completes the range for blown film units.
Blow-moulding machines
The manufacture of hollow parts through the use of blow-moulding machines is one of the most common processes in plastics processing. The multi-stage process that takes place in the machines requires solutions that take a holistic perspective of blow moulding. For example, KEB provides drive controllers for the main drive that operate at up to 900 kW and that, thanks to their compact dimensions, can fit into almost any control cabinet – and in addition they come with integrated safety technology. Thanks to the high-performance frequency inverter, it is possible to reduce the machines’ cycle times and increase efficiency. DC interconnection enables multi-axis configurations, thereby ensuring noticeable energy savings.
Downstream equipment
A wide range of end products can be produced from plastic. This places special demands on downstream equipment at the end of the manufacturing process. With practical, book-size servo inverters, KEB provides a high-performance solution for downstream equipment. One of the advantages here is that the master-slave operation is already integrated into the servo inverters. The matching control system is based on prefabricated modules, guaranteeing quick and easy programming and commissioning. For each item of downstream equipment, you will also find the corresponding control hardware in KEB’s range.

Sensorless control (SCL/ASCL)
ASCL (Asynchronous Sensorless Closed Loop) and SCL (Sensorless Closed Loop) are proven sensorless control methods developed by KEB Automation. They are advantageous in situations where high output speeds usually make it very difficult or even impossible to attach a sensor. Suitable for asynchronous, synchronous, reluctance, linear, spindle or torque motors, these methods ensure optimal and precise control and sensorless positioning – and are also inexpensive and easy to install. The underlying software contains coordinated virtual motor models.
Cooling concepts
KEB’s drive controllers take over challenging drive tasks so that machines and systems can operate with utmost efficiency. Cutting-edge, technical solutions ensure that they “keep a cool head” at all times. With its air, liquid and oil cooling systems, KEB offers three different cooling technologies which make the drives highly scalable and allow them to be used easily in various applications. Not just the cooling options, but also the way they are fitted provide machine and system operators with a high level of flexibility. In addition to control cabinet installation, the cooling systems can also be implemented as a push-through version.
Functional safety
Electrical machines and systems are subject to increasingly stringent safety requirements. Simplify your safety concept with the KEB drive controller’s integrated safety functions. Speeds, positions and various other functions are monitored directly in the drive electronics. The KEB safety control integrates the requirements of safety technology into the functional control environment. Safe communication with the control level serves as a widely used and established FSoE (Safety over EtherCat) solution – alternatively, communication via ProfiSafe is also available. In addition to, or instead of, a safe field bus system, individual safety functions can also easily be switched on and off via digital inputs. With the certification of sensorless safety functions, in some cases speed-related functions can also be implemented without a sensor system.
