Wittmann shows this year in the K more than 70 products (hardware)

At the stand of Wittmann, will be special emphasis on the specific advantages of the various peripheral equipment. On the other hand, Wittmann Battenfeld (Hall 19, stand D22) the emphasis will be put in the submission of complete work cells, showing also the latest models of machines of injection, each with its corresponding robots and peripheral equipment.

In the area of robots and automation systems, Wittmann will show as an expansion team, among others, the W873 robot and the system of control R8 with enhanced features.

The W873 model is mechanically based on the previous model W773, but incorporates many changes and improvements. The burden now reaches the 125 kg, with a maximum of 3,000 mm vertical "and" standard career The robot is also available with a configuration of vertical race of 3,600 mm and 60 kg of cargo. The career of anti-corrosion cross "X" standard is 2,000 mm and the horizontal axis is 4,000 mm (with options of extension in increments of 1,000 mm).

The robot is equipped with the new control system R8, which allows numerous functions and additional options. These include rotations preselected for the axes A, B and C. With the additional circuits of vacuum and apprehension we managed extractions of really complex parts. Cylinders integrated in the grip of the robot can be controlled as consistent and logical function blocks.

The R8 control allows the selection of numerous new functions. In addition to the already established in time real function, extraction has the best path 'TruePath', 'smartremoval' intelligent extraction, control of couple 'softtorque', PartTrack movements and saving EcoMode energy system. The user will also have the ACD (automatic detection before collision) function.

FlexSafe offers the possibility of defining areas of work of the robot, while the ACD includes a mechanism for additional security that can be automatically activated for speeds under 250 mm/s. The ACD function provides control of adjustable pair for horizontal movements. The ACD is permanently enabled in the background and recognizes the increase in the torque instantly.

The familiar role of intelligent extraction 'smartremoval' now also available in robots for lateral access W827 and W837. 'smartremoval' uses the movement of opening of mould of the tool as the basis for the initial acceleration of the axis of access to the mold. Once you reach the position of completely open mold, the robot accelerates without delay to reach its maximum speed. Regardless of the machine, 'smartremoval' can save up to 15% of the time of removal, without additional costs and at the same time protecting mechanical parts against sudden movements.

The cooling of moulds and temperature controllers are an important part of the initial activities of Wittmann. Water flow rate regulators have been considered for many decades as the standard for the cooling of machines injectors and molds in the plastics industry. The increasingly greater interest of transformers of plastic to improve control of processes, has led to the development of the new unit of measurement of flow of water 100 WFC.

The 100 WFC is a combination of regulator and flow meter. It is possible to control up to 8 circuits on a permanent basis to maintain constant water flow. All possible problems, such as blocked pipes or hoses folded due to the change of mould, can be omitted entirely. The range of flow of the WFC 100 lies between 2 and 40 l/min per circuit, with a maximum temperature of operation of up to 100 ° C and a maximum of 10 bar pressure.

The high accuracy of 1.5% FS (full scale) limits the maximum deviation only ± 0,5 l/min along the usual temperature range and therefore offers greater stability process and uniform quality of the parts. In addition to the flow of water, the temperature of each circuit is also recorded.

Atemperadores termorreguladores series Wittmann basic series is the most appropriate for applications that require precise temperature control, and at the same time great comfort for the user with an easy to use interface. The basic series covers a range of temperature between 10 and 140 ° C.

The Tempro basic C90 is based on a team without pressure (open system) and is suitable for temperatures up to 90 ° C. However, the Tempro basic C140 works according to the principles of the pressurized system (closed system) and allows the heating without problems of water up to 140 ° C.

Characteristics of standard configuration of two units:

• Controller with microprocessor auto-optimizador (accuracy of control ± 1 ° C).
• Filling automatic monitoring of leaks and level.
• Broken sensor and temperature monitoring.
• Function of detention for purge and leaks.
• Pumps of turbine instead of centrifugal pumps and mechanical design without joints.

Wittmann basic now offers option, enhanced pump and connector female for external sensors, with a choice of interface that allows direct communication between the injection moulding machine and the temperature controller. The interface works with the usual Protocol of transmission P2. In combination with the appropriate hardware (20mA, RS232, RS458) is possible to cover almost all of the interfaces.

As another option you can select the indication of the flow of water, based on the principle of pressure measurement, known to the customers in the Tempro series plus.

The new dehumidifier for wheel Drymax ATO, combines the advantages of a point of constant condensation with high energy efficiency. The dryer manages to comply with these very conflicting requirements by the completely new structure of the wheel as well as thanks to a patented mode of operation, the EcoMode.

Drying of Wittmann wheel consists of a series of Chambers that House a molecular build-up of free sieve. This design explains the great energy efficiency, since the strong movement of air in the molecular sieve permits increased transfer of energy and heat. On the contrary, honeycomb wheels consist of linear sheets which applies the secant, but from the point of view of design, is only achieved a low circulation of air. For this reason energy consumption exceeds their capacity to generate air drying.

Depending on the degree of burden of water of the dehumidifier, the ATO Drymax works in constant wheel mode or in the energetically preferred mode with "almost-2-filters", i.e. the EcoMode. The ability of hot air reaches the 120 m³/h, with what can be done any configuration of dryer compact that you record of 1, 2 or 3 drying hoppers. The dew point is in virtually all weather conditions from - 40 ° C (- 40 F) valued at - 60 ° C.

Several new products are presented in the Group of teams for the feeding of material. Among them is the centralized transport of high-performance control system eMax24, centralized filtering station XM/B and the feeder in vacuum compact Feedmax B105.

EMax24 centralized control is suitable for small power systems with up to 24 feeders and a maximum of 2 blowing stations, and offers excellent cost/performance. All the operating conditions of the system are available in a color LCD screen. The introduction of the various parameters is done through an easy to understand for the user menu. The eMax24 control is especially suitable to be connected to the feeders innovative material Feedmax B of Wittmann with pneumatic unloading Bell (and consequently of safe operation).

In addition, the centralized filter XM has been completely redesigned and is now available with a new look, as the centralized filter XM/B. The point has been created based on the design of the feeders of vacuum Feedmax B200 and B300. Its construction makes it possible to make cleaning fast and simple. The filter can be removed completely without using tools. Download Bell is used in this case also; the collector of dust can empty without problems during load cycles. Dust container is totally separated from the area of vacuum filter, which increases the security of processes and reduces downtime during production.

The vacuum compact Feedmax B105 feeder will be presented at the K 2010 for the first time, and combines the advantages of the large feeders of vacuum of the B200 and B300 series features "just in time", that are used during the operation with lower flow rates or critical materials. All components of the feeder which come into contact with plastic granules are manufactured in stainless steel and are equipped with the already known and reliable pneumatic unloading Bell. The intermediate storage of single material is 0, 5 l. The B105 Feedmax is ideal for mounting in a Wittmann MT203 hopper with variable adjustment of the capacitive sensor. In addition, this feeder is suitable to be used in combination with compact hairdryers with integrated drying air transport.

The new Gravimetric dosing Gravimax 14V occurs in the K with a container of mixing of entirely new material, which prevents the creation of static charges in the mix. Generally, the master mix or different combinations of material have the tendency to accumulate static charges, which is made worse by the prior process of transport or the movements of the mixer. This static causes problems to achieve a homogeneous mixture and directly affect the result of the dosage.

The new container of mixed with integrated "pallets of cargo" produces a uniform mixture of the various components, which have previously dosed precisely with the specific method of Wittmann RTLS (real time balance =).

At the K 2010, Wittmann also submitted a new application of labelling (IML) mold that produces round containers of 300 ml in 4 cavities with the inclusion of tags overlapping banner type. PP containers have a 0.49 mm wall thickness, the weight of the piece by cavity is 12 grams and the total cycle time is of 4.7 seconds.

The IML system will be running on a machine Wittmann Battenfeld TMXpress 210/1330. This IML application is based on the new robot's side entrance of the type W837 equipped with high-performance control R8 and allows extremely short removal times. In addition, it takes integrated a system of visualization Cognex, to check each piece individually with a high resolution camera and the In-Sight 5000 High-End connected image processing system.

In the Division of mills, Wittmann will present the model MC34 Primus. The MC Primus series of conventional mills of Wittmann, has been developed specifically for the recycling of plastic soft and medium hardness and serve as a bridge between the economic and popular line of windmills to operate next to the press line MC of Central mills of Wittmann and ML.

The new model MC Primus has a camera of Court of 300 mm x 400 mm and can achieve, depending on the size of the grid and the geometry of the parts, a performance of material between 200 and 300 kg/h. MC Primus mills have a design with open rotor that offers an optimal airflow through the Court House to prevent the thermal degradation or the cast of the material. Mobile blades inclined rotor opened in configuration 3 x 2 ("rotor in Spike"), combined with two inclined fixed blades offer a double cut stepladder further improving the quality of the crushed and minimizes dust. The rotating and fixed blades can sharpen several times depending on wear and tear.

It will also feature MAS1 MAS4 and MAS2A models with endless screw feeder to be placed under the area of the mold, as shown in the series more than Mills Wittmann.

The Sumo series of crushers without grid of slow speed is displayed, starting with the small model, Sumo Minor 1 with 1 blade and 2 rollers toothed to the Sumo Junior double 6 with 6 blades and 8 rolls of courtas well as a third axis extractor to force the pieces to the Chamber of court. All the crushers without grid are low noise, extremely compact and very suitable for the long-term use of materials hard and reinforced with glass fibre.
