Coscollola commercial offers the market a wide range of injectors

Krauss-Maffei Kunststofftechnik GmbH, whose line of injection is represented in Spain by Coscollola commercial, S. l., proposes a number of alternatives that incorporates their injectors, as for example his series CX, to achieve a productivity higher in the technique of several components. In addition, in its wide range of products includes fully electric machines in the former series of Krauss-Maffei characterized by cleaning, the speed, accuracy and profitability and whose key element of the series is the unit of closure.

With the new injection molding machines series CX, Krauss-Maffei demonstrates its competence for small classes of closing forces. Due to its efficiency, precision and flexibility, the CX adjusts ideally to a manufacture of moulding profitable injection with the maximum requirements. The machines of various components of this line have integrated a turntable with electric drive. The rotating motion can be executed in parallel during the opening of the mold. In this way, the cycle time is significantly reduced. With the eccentric patented by Krauss-Maffei, it is possible to place half of the mold on the side of the mouthpiece in the center of the turntable. This is reduced to a minimum wear of cast.

The rotary tables for the series CX are manufactured by the own Krauss-Maffei. The client produces the machine of fuel transfer of several components in the form of comprehensive solution. Movement of the turntable features are completely integrated into the MC5 remote control.

Additional injection unit can be installed in vertical, horizontal position or overlapping position. Thus, the series CX can be adapted to individual technical requirements and available placement surface.

Especially in the areas of application of automobile, electrical engineering/electronics, medical engineering and packaging, the technique of two-component and multi-component is becoming more important. With highly effective and Krauss-Maffei flexible manufacturing systems, plastics transformers can benefit from this development.

The characteristic elements of the former series - unit locking lever in Z and the Group of direct drive injection - guarantee fast, clean, cost-effective and very precise manufacture of high quality castings. On the other hand, also like especially the possibility of measuring the energy balance which allows the EX series. It uses less water and less energy, the costs of manufacturing by article descend.

The key element of the former series is the closing unit. It is composed of three plates with unique system of lever in Z. The Special kinematics and dynamics of this system ensures short cycle and drying times with high accuracy, thus raising productivity. The lever in Z of machines EX is a system of new design in which the number of moving parts is deliberately limited to eight points of articulation. By way of comparison: the traditional system of bent lever has more than twice as many points of articulation. A smaller number of components with high solicitation significantly reduces the costs of maintenance and repair.

Electrical machines of the former Krauss-Maffei series are characterized by the cleaning, the speed, accuracy and profitability.

For the unit of plastic and injection, Krauss-Maffei advocates the concept of direct drive with high torque of high torque engines. Through this system, the central force is transmitted directly to the spindle. The helical gear and the places of articulation are encapsulated and lubricated with oil. The principle of the direct drive guarantees high performance. Only the standard model reaches a speed of injection of 300 mm per second. As in the system of lever in Z, in this case also is has been dispensed as far as possible of moving parts, achieving in this way a positive effect on the accuracy, reliability and wear and tear on the machine. The plasticizing and injection are conducted through two coupled direct drives. Both direct drives are placed in a shaft and are characterized by their simple way of construction. They work without gear and are fully encapsulated. This drive concept guarantees a high record of the weight of injection and a high reliability of production.

All the drives in the EX series are water-cooled. In this way its resistance, for example, in the case of long time of postpresión, rises and improving their level of effectiveness. Cooling water that needs all machine molding by injection for a perfect operation, is used in double way in the EX series. It is cooled converters and drives. In this way considerably reduces consumption of cooling water and ensuring a more effective dissipation of waste heat. Especially in the clean room manufacture exploit the advantages of the drives water cooled. They do not generate movement of dust and air. Cooling efficiency allows that conditions remain constant in the air-conditioned spaces.

The former series, thanks to its high modularity and adaptation capabilities, responds to the demands of a flexible manufacturing. It has a wide range of different plastificaciones and systems adapted to different materials. The former can be equipped without problems to become a unit of automated manufacturing. With its large areas of fixation, the machine itself offers plenty of room for innovative technologies from moulds. And it is a "global player" in the most literal sense, because it can be used on all networks of power supply of the world.
