K 2007 preview

KOCH to exhibit superior technology with components from its successful modular system

The Navigator fully automatic material feed system, dry air dryers from the EKO range with eco-control system and integrated touch panels, the Graviko dosing system and KKT mobile auxiliary dryers - these are the highlights announced for the Werner Koch Maschinenfabrik GmbH stand (10A21 in Hall 10) at K 2007 in Düsseldorf.

Navigator is a patented material feed system for plastics processing that ensures that no residues remain in the distribution system. Fully automatic and program controlled, it links machine lines with the appropriate material lines before the conveyor feeds the relevant machine. The linked feed lines are locked together to make transport of the granulate even safer. This allows any material to be connected to any machine. Suction valves clean the lines completely after each conveying cycle. Navigator can also be integrated in existing conveying systems; there is no need to change their basic design.

Koch is also exhibiting the Öko control system for its CKT and EKO dry air dryers. This is a patented energy-saving drying solution with careful material handling. It prevents sensitive materials such as PA, PC, LCP or POM in the storage containers from become overdry or sustaining heat damage. It also makes energy savings of up to 40% possible. Predried material can be called up at any time. The integrated Touch Panel with a new 25% larger coloured screen offers the user an even more convenient way of viewing the whole system. Drying temperature, regulation of the air volume, hold time monitoring, throughput calculations and energy saving are shown clearly and it is easy to adjust the settings. The user now has a window showing clearly the dew point at intervals over the last 24 hours, thanks to a new software enhancement. Analysing these readings shows the actual load on the dryer and indicates problem-free operation.

The patented Graviko system doses miniscule quantities precisely and reliably with the highest reproducibility. With a slider, or alternatively using a star feeder (chamber volume dosing), the individual components are dosed into a container with a scale. There is also a dosing slider available for very small quantities of 0.3 g and over. A scale then records the actual weight of the individual components which is reported to the KOCH control system and compared with the set weight. With its closed chamber volume, the patented GRAVIKO system offers precision dosing within +/-2 grains / 1000 grains. Graviko can be used directly on injection moulding machines and is also completely compatible with other dosing devices, mixers, conveyors and other accessories from Koch-Technik.

The KKT auxiliary dryers are suitable for drying and conveying where space is at a premium. These mobile dry air dryers can be used for all practical applications and even for very hygroscopic plastic granulates. The switch control system allows the drying process to be adjusted to the throughput rate and the initial moisture level of the granulate making energy savings of up to 40% possible. The standard KKT model can supply one or two injection moulding machines with dried granulate. A specially designed microprocessor control unit guides the user through the program with self-explanatory instructions and ensures optimum operational safety.

For more than 33 years, the name Koch-Technik has been synonymous with innovation, precision, modular flexibility and cost-effectiveness in the mixing, dosing, conveying and drying of plastic granulates. Use of our equipment and systems in more than 4,000 plastic processing companies around the world document the acceptance and high efficiency of these systems in everyday production work.
