ewin ECONOMIC INNOVATION AT IT S BEST ALL ELECTRIC All of the ewin s movements are performed by servoelectric drives. The allelectric drive helps you to achieve bestinclass efficiency for the entire machine. Maximum precision of all movements and impressive process stability guarantee the highest levels of good parts. SAVING COSTS Thanks to consistent use of allelectric drive technology with bestinclass efficiency, the ewin is a genuine energy saving champion. This high energy efficiency saves you cash. Shot for shot. This helps you keep your ongoing operative costs down to an amazingly low level. SAVING SPACE The ewin helps you save space. Thanks to its extremely compact dimensions, the machine makes optimum use of your shop floor space, giving you more value for your money. This means: more performance per cubic metre. Or to put it another way: more machines, and thus more productivity per facility. FAST. FASTER. ewin. The ewin sets a new standard with up to 22 m/s² acceleration on the injection axis. Thanks to this, and many more impressive parameters, it guarantees short cycle times and maximum productivity in your operations. FLEXIBLE AND MODULAR WINTEC ewin. A machine that gives you more. A machine that combines great performance with amazing precision. Allelectric. A machine that offers you a huge amount of freedom. Enough freedom to be able to design your individual injection moulding applications with the required degree of flexibility. A machine that takes up very little shop floor space despite its amazing performance. And a machine that is extremely frugal. In ongoing operations, because it uses very little energy. The ewin uses the proven WINTEC C2 control unit which offers maximum flexibility on all WINTEC machines. With the ewin you can also implement complex injection moulding applications in a highly efficient and userfriendly way. 6 7
ewin clamping unit CLOSE TO PERFECTION 1 Automatic mould height determination Automatic mould height determination on the ewin saves tooling time and prevents incorrect settings. For each mould change. The mounting height of the mould is automatically determined by an intelligent program. 2 High precision, dynamic clamping drive ensures short drycycle times and impressive productivity. And perfect integration with takeoff units. 3 Sensitive mould protection Protection against mould wear. For improved availability. Autoprotect. 6 Central clamping force measurement The ewin measures the clamping force via a sensor on the face plate and not on a single tiebar, in contrast to conventional systems. Central measurement helps you achieve maximum measuring assurance. Linear guidance of the moving platen The moving platen on the ewin is guided in a virtually frictionfree way. Instead of tiebar guides, it relies on highprecision linear guides. This not only saves energy, it also increases the service life of the clamping unit. Worn tiebars or bushings are thus a thing of the past. 5 Automatic clamping force correction for high process assurance When the mould heats up and expands, the clamping force increases. Intelligent clamping force correction compensates for this effect. With a mind to continuous process assurance. 8 9
ewin injection unit INJECT THE FUTURE Highprecision sensors and fast control Highly precise and extremely fast this is how the injection unit on the ewin works: for example, the screw position is measured by the encoders on the servomotors. This ensures maximum resolution for highest precision and process assurance. 1 3 2 Powerful servomotors ensure high injection speeds and breathtaking acceleration. And: they allow for long, high postinjection pressures. Intelligent contact force system Force is applied symmetrically by two spindles. The contact force, which is held by the motor brake, is configurable and can be precisely adjusted to match each mould. The nozzle movement is configurable via a profile. Parallel motion means valuable cycle time savings. Pressure membranes measure the peak, postinjection and holding pressures outside the nozzle area. This avoids the measured value being influenced by different processing temperatures.for each mould change. The mounting height of the mould is automatically determined by an intelligent program. 5 Saving tooling time Swivelout injection unit included as standard this means optimum accessibility of the screw tip and minimal overhead for changing and cleaning the screws. But barrels can also be changed quickly on the ewin. Thanks to the intelligent quickcoupling system. All told, this saves you much valuable tooling time. Longer service life, less maintenance overhead thanks to oil sump lubrication of the spindles The spindles on the injection unit are optimally lubricated, being encapsulated and running in an oil bath. This extends the spindle service life and keeps the entire area clean. Another benefit: the spindles are highly efficient as there is no need for oil cooling. And you make substantial savings on maintenance costs, as this lubrication system uses inexpensive standard oil. 10 11

ewin ADVANTAGES YOU CAN RELY ON CLAMPING DRIVE: HIGH PRODUCTIVITY, PRECISION AND DYNAMIC 1,700 DYNAMIC EJECTOR PRECISE AND DYNAMIC 1,275 Short drycycle times for impressive productivity. This is what the dynamic clamping drive with its optimised toggle lever geometry offers. Due to FEM (Finite Element Method) optimised parts, only very little mass is moved. This improves the dynamic while at the same time reducing the energy consumption. 1,0 0,850 0,25 ewin 50 obey cycle time ewin ewin 100 ewin 180 The ewin is equipped with a servoelectric ejector as standard equipment. This means that parallel motion of the ejector can be optimally adjusted to match the mould movements. Thanks to fast acceleration behaviour and high reproducibility of the ejector positions, the mould takeoff process can be accelerated, thus saving cycle time. SENSITIVE MOULD PROTECTION AUTOPROTECT Maximum safety for your mould. This is guaranteed by the selfteaching and highlysensitive Autoprotect mould protection program. It automatically determines the mould protection force and can be set up individually for each mould. Mould wear and maintenance costs are thus reduced to a minimum. And machine availability, and thus productivity increase substantially. v [mm/s] F [kn] 500 25 357 0,8 0,5 0,0 283 27 13 0,3 1,2 1,8 20.0 18.0 16.1 1.2 12.2 10.2 8.2 6. 2. 0.5 injection speed [mm/s] * injection pressure injection performance [mm/s] 500 375 250 125 0 1000* 2000* 3000* 000* HIGHEST INJECTION PERFORMANCE To achieve the maximum injection speed at the highest injection pressures, extremely powerful servomotors are required. The ewin again sets standards in its class. Thin wall thicknesses and long flow channels are thus child s play for the highperformance injection units on the machine. 1 15
ewin ADVANTAGES YOU CAN RELY ON LONG POSTINJECTION PRESSURE NO PROBLEM Long, high postinjection pressures can be a major challenge for electric machines. The motor and controller overheat after a short time at high pressures and the postinjection pressure collapses. The rule is: the more powerful the motor, the better the postinjection pressure behaviour. And here too the ewin sets new standards in its class. The powerful servomotors can easily hold long postinjection pressures. ewin LONG POSTINJECTION PRESSURE injection unit screw postinjection pressure without time limit 50 15 mm 2075 bar 170 22 mm 200 bar 310 30 mm 115 bar 0 35 mm 1090 bar 70 5 mm 1010 bar 90 50 mm 960 bar TOP LEVEL ACCELERATION The dynamic servomotors of the WINTEC injection unit accelerate the injection movement from 0 to 500 mm/s in less then 30 ms. This outstanding increase in speed in combination with fast injection speed offers the best perfromance, especially at short injection strokes. PARALLEL MOVEMENTS REDUCING CYCLE TIME Due to the fact that every movement has it s own servomotor, parallel movements are possible in standard. For example ejector forward parallel to mould opening or parallel plastizicing to mould opening/closing. This saves cycle time and increases you efficency and productivity. TAKING PRECISION TO THE HIGHEST LEVEL Highquality sensors and fast controls are required for highest precision and repeating accuracy. This is the only way to control a dynamic injection process. The ewin offers the best prerequisites for this. All pertinent positions are measured with highest resolutions via the increment shaft encoders on the servomotors. This guarantees positioning repeatability of +/ 0.02 mm. The peak, postinjection and holding pressure measurement is not influenced by external factors; it occurs directly on the screw bearing and thus has a direct mechanical connection to the molt prechamber via the screw. The pressure sensor is wearfree and calibrated for its entire service life it impresses with its extremely high resolution. This guarantees maintenancefree longterm precision. 16 17
