Used for lightweight construction
With the new vertical large-scale machine series ENGEL v-duo the manufacturer of injection moulding machines ENGEL AUSTRIA opens up new areas of application in lightweight automobile construction. ENGEL delivered a first ENGEL v-duo to the BMW Works in Landshut.
The new, vertical, large-scale machine offers a clear-cut approach to economical series production for thermoplastic as well as thermoset composites. Both in overmoulding of organic sheets and tapes, and in HP-RTM processes, if often makes sense to work with gravity. This reduces the effort in the handling of parts and the fixation of insert parts in the mould, and also facilitates manual intervention.
The ENGEL v-duo 3600 with a clamping force of 36,000 kN, which was delivered to BMW, will be used for manufacturing large structural elements from fibre plastic composites using the HP-RTM process. It is equipped with two horizontal, moving slide tables to remove finished parts and insert new fibre tissue during the pressing process. This manufacturing principle reduces cycle times and increases energy efficiency, because the mould is only open for a brief period each cycle.
Footprint compared to traditional presses significantly smaller
In contrast to presses traditionally used for fibre composite applications the new vertical machine by ENGEL stands out with its comparably small footprint. The machine is only about half as high and the machine weight is also significantly lower, which reduces the overhead for building a foundation.
The clamping unit can be accessed from all four sides instead of just two. It features a very high degree of rigidity and excellent mould fixing platen parallelism. The regulation of platen parallelism for injection compressing moulding is included in the standard version of the machine.
Since the ENGEL v-duo completely dispenses with hydraulic accumulators and already uses the ENGEL servo-hydraulic system, ecodrive, in its standard version, it sets new standards in terms of energy efficiency for large-scale machines. When using ecodrive, the motors are only active when the machine is actually moving. Idle cycle losses are thus prevented.
