Solutions for efficient production and excellent products
KraussMaffei Berstorff tires are economical solutions for producing high quality tire components. Through the design of special machines, the system highlights due to:
High throughput in low dimensions and optimal weight tolerance and uniformity
Short retrofitting time during mixing or changing geometry
Waste starting low. Optimized geometric screw for each mixture

Mulitplex extrusion system with 7 extruders
The KraussMaffei Berstorff extrusion system is manufactured with the highest quality and highest output and is equipped with various extruders (GE-SC or GE-W, GE-KS) and sizes. By modular construction, the system configuration, corresponding to the desired cross section, is relatively simple to set up as a double, triple, quadruple, quintuplex and hexaplex unit.
KraussMaffei Berstorff's multiplex systems are formed in piggyback designs to achieve the highest product quality through symmetric material flow in the extruded head. In addition, the compact design offers significant space benefits. An additional feature to meet high quality requirements is the special design of the flow channel in the extruder. They create a very soft and non-invasive transition for the extruded diameter of the screw from a flat, rectangular shape. In addition, the deviation of the volume flow in the channel drops to a minimum.
All process sequences are continuously checked by a monitoring system. Through it, high operational reliability is ensured.
Throughput of up to 10,000 kg / h or approx. 30,000 tires a day are achieved with modern systems.

The GE-KS rubber extruder and GE-KS vacuum are all-round machines for many applications. Their versatility and reliability make them truly successful machines in the process. The appeal of battery pincers is further enhanced by the device's extensive range of extras such as automatic battery adjusters, replacement wet sleeves, broken screens and high-performance screws. .
The advanced technology handles a wide spectrum of rubber compounds with different viscosities with just one type of screw, without the need to convert.
We are equipped with extruder Degge-GE EG with a vacuum chamber and the procedure uses battery-barrel technology. The machines offer high output, low melting temperature under injection molding and better dimensional stability for extruded products.

A definite feature of the KraussMaffei Berstorff GE-SC grinder. Pinconvert® is a butterfly unit built in the area near the maximal sheath volume of the sleeve.
It has symmetrically distributed legs around the perimeter that pierce through the sleeve of the sleeve. Can be manually or hydraulically adjustable and allow to reduce the volume of the channel to zero in this area.
Because this allows for production, melting temperatures and uniform performance parameters are influenced and optimized, GE-SC extruders provide you with a guarantee of flexibility and adaptability. can not beat.
We have expanded the options available for the GE-SC's Pinconvert® extruder using specially developed de-gasification systems. The gauge elements are of great importance for extruder models, well, as the extrusion level can be affected by using the penetration depth of the battery before it reaches the deaerator.


Hot food The extruder of KraussMaffei Berstorff GE-W has proven itself in the production of many types of natural and artificial rubber. They are fed as units downstream of the mills, either continuously with strips or continuously with uncoated rubber rolls. They are made of plastic heated rubber. In addition, they can be arranged as exhausters just below the mixer. In this
form they receive screws with larger diameters and tamping dies as a means to facilitate infeeding.

The variety of tires creates complexity, size and change in the production line. The head of each extruded system will become a measure of quality and efficiency in tire production.
To achieve fast repair times in case of frequent change of width while using the same mixture, pressing the KraussMaffei Berstorff die is equipped with a "double wedge wedge". By opening the wedge-shaped wedge, only the last die can be replaced, while the wedge-shaped wedge holds the holder and the bar in the closed position. This minimizes scrap and allows producers to start again quickly.
The top and bottom of the head can be opened separately, to reduce the setting time and the random waste when extruding to change the compound.
Another option to reduce setup time is to use a cassette changer. In this case, two cassettes with the connecting rods and the last bar are used. While one tape is used in the production process, the other can be prepared for the next batch in a changed location by equipping a connecting rod and die.

The electrical equipment for the KraussMaffei Berstorff extruded system is modular design based on the most up-to-date technology of the art. Custom configurations can be made in the shortest amount of time without problems.
The extruders are characterized by their microprocessor drives, access to actual digital values and parameter values set via the bus connection. This technology ensures high repetition, precise control and dynamic speed control. These factors are of particular importance for the quality of the extruded profiles. Control software developed by KraussMaffei Berstorff minimizes startup wastes and ensures compliance with measurements and weight balances. of the extrusion mold in the production process. The system continuously measures the weight and the measurement and speed of the screw, the flowing pressure and the melting temperature in individual extruders. In case of deviation of the actual values from the set values, or the parameters of the process are adjusted separately from each other or - depending on the influence on the composition - the parameters of all extruders 
The auxiliary drives are equipped with low-maintenance three-phase motors and vector control frequency converters. Non-contact scanning systems such as CCD cameras, ultrasonic sensors and digital rhythm controllers Special numbering allows the transport of stress-free materials. Each system is controlled by a digital software controller, ensuring optimal speed for the following drive.
The automation systems of each machine are networked through TCP / IP and attached to an intuitive display. The operator-friendly image and formula management system clearly provides a plan. flexible production, high product quality, minimal startup waste and short travel times
