They were also unveiled several cutting-edge technologies of the German company

On May 3 Coscollola commercial gathered at the premises of the Ascamm Foundation, in the Barcelona town of Cerdanyola del Vallès, customers to publicize the electric fuel transfer Krauss Maffei model EX 80/380. Visitors were able to see in operation process of injection and attend the presentation by the engineer responsible for technology multi-component of Krauss Maffei, Jochen Mitzler, on a day where the technologies of multinyección, the Spin Form (injection confronted with rotating dishes) and Twin concepts highlightedIMC (Injection Molding Compounder) and the benefits of fully electric machines, as well as their applications. All of them, advanced developments that provide great benefits to customers, allowing an increase in productivity in the process of injection.

The star of the day was the fuel transfer model KM80-380EX of the former electric series, featuring models with closing forces between 500 and 1600 kN. The electric fuel transfer shown on the day injected caps with seal in HDPE in a cast of eight cavities with a cycle time of 4.7 seconds. As pointed out Ricardo Coscollola, the fuel transfer shows the precision of the former series, as well as its speed and its low level of noise.

The former model is ultra flexible due to 4 units of injection by tonnage and 4 diameters of spindles per unit of injection; also the wide and varied experience in plasticizing of Krauss Maffei, excellence in application engineering support and a network of support around the world.

The former series is characterized by high profits with minimum costs. This can be seen in the first instance in its energy balance. The former series consumes less power and cooling water.

In addition, it convinces with its minimum dry cycle times and their high injection speeds.

On the other hand, all the elements are prepared so that ensure a high level of availability, provide full maintenance and allow a comfortable handling of the machine.

According to Jochen Mitzler of Krauss Maffei, "the former fuel transfer speed is as vital as saving energy". All electrical machines save energy: low voltage dissipation also means a lower consumption of cooling, saving up to 70 per cent water and energy saving is approximately 50 per cent depending on the cycle. The reason is the increased efficiency of the electro-mechanical construction.

Also, the closing "Z" that incorporate the electric injectors of Krauss Maffei of the series EX is extremely rapid opening and closing. No extra time for the generation of clamping force, the dry cycle of the KM80 EX time is reduced to less than 1 second.

The closing mechanism is a direct movement. Only 8 points of pivot, only 4 arms for movement and application of the clamping force and many fewer moving parts. More than 7 million cycles (in 9 months of continuous operation) with zero defects are possible.

This allows a lower maintenance and high availability.

The closure is totally clean, because that is the first closure that works without fat. The lubrication oil is encapsulated in all points of pivot and marches, are much reduced loss of lubricant, the ejector is encapsulated and plates guided without bars of subject, therefore free of contamination.

All main electrical controls and converters are cooled by water (greater load capacity and not increasing the ambient temperature in the areas of production with air conditioning). Also, the operation is performed without any noise.

Electric transmission technology is more accurate than the hydraulic transmission. The movements are more accurate and reproducible, the proportion of rejection and the effort in quality control are less, in the same way that the processes are more stable and precise.

According to the German representative of the firm, the demand for the automotive industry is characterized by a marked trend towards the construction of light weight, a careful design, the integration of additional functions, multifunctionality and the cost pressure. In this regard and to grow in the business of plastics, the German company proposes several solutions: the specialization of the processes, achieve very low rejection rates and develop a high degree of automation. To achieve this, he presented different technologies.

TwinForm technology is a new concept for double molds that allow duplicate production, providing higher productivity and flexibility.

This system allows you to use molds and standard hot cameras, offers a short flow and low loss of pressure in Hot House, as well as the possibility of applying colors, materials, or weights of injected different.

Coscollola commercial, representative for the companies Krauss Maffei, Berstorff, Motan and Regloplas Spain, is a company able to offer solutions for the injection of plastic, from storage, drying, transportation and mixing of material into pellets for feed manufacturing machineas well as atemperadores of mold, injectors machines and extrusion facilities.

A TwinForm machine is equipped with a separate for each plate injection unit and its drive is integrated into the machine.

Using standard moulds rather than conventional flat Gets a high flexibility in adjusting the production variants claims. When the demand for high-volume seasonal products decreases, molds can pass from a TwinForm machine to a standard machine.

It allows a simple color change, fast in comparison with the technology of mould of flats, and a simple boot for large cavities 96/96. Injection units are also required smaller so the plasticizing is faster. Another added advantage, with the use of two machines, is that it allows the clamping force reduction and the reduction of the electricity and water.

Also avoids the difficulty (with respect to the mould of double floor) of the drinking system of hot House which eliminates the leakage and reduces the useless time.

Allows two solutions for intermediate fixed mould plate: either mechanical solution with gears or a water solution with sliding table and adapter. The anti-corrosion of parts is carried out with robot, where the pieces are preorientadas ready for mounting.

Spinform technology stands out for its reduced Assembly costs and because it opens up a new range of opportunities.

It provides a high quality of the product through the functional integration (intelligent design), long-lasting connections and the right mix of material.

Productivity is also greater, as it eliminates editing errors, require less logistical efforts and provides double production capacity.

Manufacturing costs are also reduced when the Assembly is integrated into the mold, the set up is fast and eliminates rejections.

Injection Molding Compounder (IMC) technology is the integration of a fuel transfer and an extruder which reduces the costs of material 0.26 - 1 EUR/kg, reducing process stages.

They provide a better quality of product, using longer fibres, with a better homogeneity and a lowest temperature of mass, as well as a great flexibility, strengthening of fiber, mixing and resins.
