Robust plate design for continuous and precise production with extreme loadsThin-walled packaging applications are generally fast and operate over long periods of time. ELIOS machines are perfectly equipped for continuous runs with extreme loads. A high-quality cast iron material with a ferritic structure is used for the plates, which feature a load-optimized geometric shape. The high overall strength ensures an optimal flatness of the clamping plates. The moving plate is supported by four tolerant linear guides in a manner that is particularly solid, and it moves with minimal friction. "The user benefits from an optimal introduction of force, a lower required clamping force and a very low wear of the machine and the mold," Davatz emphasizes. "What is particularly fascinating is how harmonious and smooth the clamping unit operates. It's easy to forget that multiple tonnes of weight are being moved back and forth in short cycles," Davatz adds.
Modular injection unit for dynamic injection and large flow path/wall thickness ratiosThe injection side can optimally be configured to the demands of the respective application with different injection unit and plasticizing unit sizes. The injection units 1000, 2000, 2900, 4200 and 6000, each featuring two or three different screw diameters, are available for the ELIOS 4500. The user can choose among a total of 12 injection unit-screw combinations. The selection for the ELIOS 5500 starts with an injection unit size of 2000 with a total of nine combinations. Across the entire series, customers can select from a total of 33 combinations of clamping force, injection unit and screw diameter. The hydraulic injection cylinder of the hybrid injection unit in combination with the two-valve technology ensures a very high injection performance, while the servo-electric drive of the dosing axis contributes to a low electrical energy consumption.
The two servo valves respond very quickly with a reaction time of no more than 11 milliseconds and permit dynamic injection with up to 2200 mm/s and an acceleration of up to 20 G. Large flow path/wall thickness ratios of up to 350:1 and over can be achieved effortlessly. The position and speed-controlled movement of the injection unit with torque-free nozzle contact pressure allows total precision and the best shot-to-shot consistency on the market.Top media flexibilityThe media equipment catalog provides customers with a wide range of options. The connections for hydraulic mold auxiliary functions can optionally be attached to the fixed (operating side) or the moving plate (operating side or non-operating side). The air valves can also be positioned with great flexibility. It doesn't matter at which plate or whether the valves are supposed to be accessed up top, on the operating side or the non-operating side. The pressure regulators can optionally be integrated in the protective cover on the operating side or the non-operating side. Depending on customer specifications, the entire cooling water installation can be done with high-quality components selected because of their longevity. For power connections, socket boxes with integrated circuit breakers can be installed in various locations.
