NEW! Automatic packaging systems
Meeting challenging packaging demands by innovative solutions
Coperion’s new IBP 250/500 packaging system (IBP = Integrated Bagging and Packaging machines) concentrates all weighing, bagging, marking, qualifying and palletizing functions in one small machine with a footprint of 8,500 x 2,200 mm. The product inlet is at a height of 2,700 mm including the product dosing and weighing system. The machine can be used to pack compounds of PE, PP, ABS, PC, PTA and PA including masterbatch applications. These machines are easy to operate, very flexible, adaptable to a wide product range and easy to maintain.
They operate reliably under harsh industrial conditions. In addition, the system provides useful statistical reporting and diagnostic control combined with efficiency monitoring. This feature combined with remote technical assistance guarantees a reliable and efficient operation.
The Coperion packaging solutions include several models of FFS machines and palletizers on motorized karts that can be easily adapted to existing plant layouts. These karts are able to move on rails or with independent wheel drive to allow X and Y movements without appreciable turn radius.
All Coperion bagging and palletizing systems can be integrated into existing plant data acquisition systems for quality control and packaging efficiency control. The modular design allows an easy upgrade of machine performance to be made without the need to replace the complete system. A new cleaning system allows reliable cleaning to take place in less than a minute, without the need for operator attendance. This reduces the risk of product cross contaminations with a significant increase in the overall line efficiency.
With the latest series of bagging and palletizing machines Coperion now offers plastics compounders reliable and innovative solutions to meet the challenging demands of automatic packing systems, especially when frequent product changeovers are required.

NEW! Laboratory extruder ZSK 26 Mc18 – efficient, versatile and user-friendly
Greater flexibility through exchangeable process section
One of the latest developments of Coperion to make its debut at K 2013 was the ZSK 26 Mc18 twin screw laboratory extruder with 26 mm screw diameter. This new extruder offers all the advantages of the ZSK Mc18 series; it has a simple design, it is operator-friendly and easy to clean. It is suitable for the development of formulations, for conducting sample compound trials and for the production of relatively small batches with up to approximately 180 kg/h.
Compared to its predecessor this newly developed laboratory extruder of the ZSK Mc18 series is capable of an increase in throughput of up to 100%, as the specific torque has been increased to 15 Nm/cm3. It is more energy efficient thanks to the reduced specific energy input. The increased filling degree and the lower melt temperatures ensure extremely gentle compounding. The new ZSK 26 Mc18 is a mobile unit and requires only a minimum of floor space, as the control cabinet is integrated into the base frame of the machine. Heating and cooling are installed ready for use.
The laboratory extruder offers additional flexibility since it can be easily converted into a ZSK 27 Mv PLUS with a much larger free volume. Configured in this way the extrusion system permits the compounding both of products with high torque requirement and of low bulk density products that require high free volume. Conversion merely entails exchanging the process section (the replacement process section is pre-assembled), which is done with the aid of an assembly trolley. All connections – screw shaft coupling, heating system, cooling system, temperature measurement – are plug-in-coupled for time-saving installation. The ZSK 26 Mc18/ZSK 27 Mv PLUS permits direct and reliable scale-up to larger machines of the ZSK Mc18 and ZSK Mv PLUS series.
Following a complete redesign, the laboratory extruder is now equipped with a central water and power supply system. The cooling water manifold is installed in the totally enclosed base frame; a covered multiple socket strip supplies power to the heater cartridges. The single-piece stainless steel cover of the process section serves ideally as a dust and safety guard and – like the smooth surfaces of the base frame – is easy to clean. Because of the high specific torque, the screw shafts are manufactured from materials developed by the aerospace industry and have already proved themselves in the other sizes of the Mc18 series. The newly improved quick-release screw shaft coupling, which works on the tried and tested plug-push-principle, permits rapid exchange of the screw shafts and considerably reduces cleaning times when changing over from one colour or formulation to another.
The newly designed die head features an optimized heating system and can be opened simply by loosening one single screw, for example, to replace the die plate or the breaker plate. A newly designed swivel arm permits direct machine-mounting of the ZS-B twin screw side feeder – for the feeding of fillers and additives – or the ZS-EG twin screw side devolatilization unit.
The new CSpro control system is available in two versions: the basic version covers all standard applications, while the medium version offers additional functions such as order and formulation management. The laboratory extruder can also be equipped with a high-resolution torque measuring instrument, the readings of which permit a considerably more accurate calculation of specific energy input in order to enable even greater precision when scaling-up. The readings also provide information on the dynamic behaviour of the two screw shafts and make optimized configuration of the screws possible.

Smart Flow Meter for in-line weighing applications
Intelligent solution for metering, registering and monitoring of bulk material flows
Utilizing the principles of Newtonian physics F = ma (Force = Mass x Acceleration), the Coperion K-Tron Smart Flow Meter (KSFM) is used in process applications that need reliable metering, registering or monitoring of bulk material flows.
No Moving Parts
The Smart Flow Meter has no moving parts. The bulk material flows through two force sensor stations that have no mechanical effect on the material. Bulk material flows by gravity into the upper measuring channel, an inclined chute mounted on a force transducer where the force, acting perpendicularly on the chute is measured as mass. The bulk material then flows into the lower, vertical channel which determines velocity or acceleration rate. From the signals of these two sensors the flow rate is determined per unit of time. The measured bulk material can be granules, chips or powders used in plastics, chemicals, animal feed, grain, etc; with good flow characteristics. Since there are no moving parts, bulk materials are handled gently.
Applications include material flow control within a production line, measuring filling or discharge of materials from storage, inventory control, and quantitative bulk goods measurement. The Coperion K-Tron Smart Flow Meter offers low-headroom and is a cost-effective solution for in-line weighing applications.
Models include the KSFM-275-B for bulk material flow of 3.3-60 m3 / h and KSFM-350-B for bulk material flow of 8.3-200 m3 / h.

27th International Plastics Technology Colloquium of the IKV
27th International Plastics Technology Colloquium of the IKV
Coperion ZSK 26 Mc for direct extrusion
On March 19 and 20, 2014, the Institute of Plastics Processing (IKV) at RWTH Aachen University invites to the 27th International Plastics Technology Colloquium in Aachen. During the institute visitation tour IKV 360° a direct extrusion line for polyamide 6 semi-finished parts based on the anionic activated polymerization of ε-caprolactame will be presented. Heart of the extrusion line is a twin screw extruder ZSK 26 MEGAcompounder provided by Coperion. To realize the direct extrusion process, the monomer residue is already reduced in the twin screw extrusion process by a suitable degassing strategy.
Besides this highlight a broad overview of new production processes, methods of product development and corporate strategies in plastics technology is presented at the colloquium. With six plenary lectures, 18 keynote speeches and 36 IKV presentations, the Colloquium will offer you a wealth of new ideas in a unique expert environment. With over 700 delegates expected to attend, the Colloquium will be the meeting point for innovative plastics companies. There they will gain a fresh impetus by exchanging ideas and information with experts from IKV and its network.
