The month of June krauss maffei, company represented in Spain by Coscollola, convened the world press in Zurich (Switzerland) to announce their numbers and present their great innovations in the face of a K which themselves responsible for the company is presented as a unique opportunity to return to the path of growth. The company, which hopes to close the fiscal year matching numbers of turnover of the previous campaign (750 million euros), presents a new system of extrusion, called QuickSwitch, with which you can change the diameter and the thickness of the wall of the pipe in a matter of minutes in the appointment of Düsseldorfwithout interrupting production.
"To be successful we have to adapt to new needs and so we we have automated, with much more demanding systems that our clients demanded us." Thus summed up Dietmar Straub, CEO of the company, which was the new line that had dominated Krauss Maffei for the future. The first results can be seen in a K 2010 responsible for own defined as "fundamental".
CoverForm: resistance to scratching and efficiency
With the moulding process CoverForm for the production of coated parts resistant to scratches in a single injected, KrausMaffei presents in association with Evonik Röhm, an economic and efficient solution for mass production. CoverForm allows the implementation of a functional layer of PMMA components in a continuous process. In this way shortening the current value chain of 14 stages in the manufacture of components covered in a single step in a production line, followed by the receipt of the finished parts and quality control.
The
solution includes cells for the manufacture of Kraus Maffei attached to the system of material, consisting of the substrate and the reactive solution of Evonik. The
excellent properties offer a great resistance to scratches and a high chemical resistance to the surfaces of intensive use, for example in the automotive industry or in household appliances and phone screens mobile.
Control of high precision of fully electric injection unit, is the basis for a repeated and exact reproduction of layers in a micrometer-range
In the K 2010 Kraus Maffei displayed in action process, ready for series production. The hydraulic unit of closure of the hybrid fuel transfer CX 200-750 has the latest technology in compression and a dosage of painting perfectly adjusted to the process. Control of high precision of fully electric injection unit, is the basis for a repeated and exact reproduction of layers in a micrometer-range. Addition,
Kraus Maffei, has further developed its system of heating of the mould dynamic to work with multiple cavity moulds, by integrating a complete solution automated. Insulating sleeves Blue Ecopac Power and the use of the blue energy of the servo pump technology ensure high energy efficiency of the solution.
Innovative engineering to reduce the consumption of materials and increased flexibility in extruded tubes
The costs of raw materials have a decisive impact on margins in the extrusion of pipe. This explains why Krauss Maffei Berstorff offers a number of significant innovations in process aimed at reducing the consumption of material.
System of extrusion QuickSwitch allows you to change the diameter of the pipe and the thickness of the wall in a matter of minutes, without interrupting production. With the touch of a button, the extrusion line changes completely and automatically to the selected dimension. QuickSwitch also helps to reduce material costs, since the amount of waste produced during the transition is much lower than with conventional extrusion lines. Also removes by full time and effort in the change and reduces the energy used to heat the new heads to the maximum.

Energy saving in the extrusion
Krauss Maffei Berstorff presents the model ZE 60 to UTX, an extruder of double spindle with a maximum speed of 600 rpm, as well as active and passive features to improve energy efficiency. A large number of tests carried out by the specialist in extrusion machines in Hannover have revealed that substantial energy savings can be achieved using larger extrusion machines operating at speeds averaging, using small machines at high speeds.
For some years, several manufacturers have offered extrusion machines with high speeds of up to 1,800 rpm, combining high speed with a size of machine relatively small. , However, was not taken into account the fact that the power implied a high energy consumption.
In a context of energy costs in constant growth and the growing demand for machines that save energy, experts from Krauss Maffei Berstorff dealt with this issue and found that the use of an extruder more than lower speed offers crucial level advantages energy. In the preparation of compounds PA 6 with 30% glass fibre and a rate of output of 2,100 kg/h in a 60 ZE to UTX at 1,200 rpm, for example, the requirement of energy is 0.21 kWh/kg, while with a machine model top of machine, i.e., the ZE 75 to UTX, at a speed of 600 rpm, needed only 0.18 kWh/kg. Taking into account the increase in investment and operating costs of the largest extruder, with pure investment recovery period is about two years, depending on the cost of the energy

EasyClean: substantial reduction of time in the preparation of compounds
In the K of this year, KraussMaffei Berstorff has a line for the preparation of compounds with the new design EasyClean. This innovative solution consists of several new components, details and improvements that reduce by 40% the time line cleaning of extrusion in a change of format.
The new needs - such as small batches with differences between if, or the production of ' just-in. time'-involve frequent changes in the settings of the machine. To guarantee a service to the flexible client, combined with a high competitiveness and profitability, guidelines for preparation of compounds used for this purpose have to provide a universal application, as well as a rapid implementation to point. With EasyClean, KraussMaffei Berstorff offers its customers a fast and easy conversion of the machine for production processes, without long periods for stops or failures in the process of loading.
Full composition of modular design line.
The line for the manufacture of compounds that are on display at the 2010 K is equipped with a 60 ZE UTX extruder in version EasyClean. The complete line is designed according to the modular concept of KraussMaffei Berstorff. In addition to reducing the time of on-site installation, design modular provides a substantial reduction in costs in general, are not generally required steel structures and needs are limited to the provision of an enabled area.
