WITTMANN to demonstrate bottle caps production at Drinktec
At the Drinktec from September 15 to 19, the WITTMANN Group will demonstrate the production of screw caps for drink bottles with its EcoPower Xpress 160/1100+ and HDPE from TotalEnergies OneTech Belgium, using a 32-cavity mold supplied by HTW, Austria.

EcoPower Xpress 160/1100+.

Screw caps for drink bottles.
The EcoPower Xpress is an all-electric high-speed machine. Its dynamic drive axes for injection, closing and opening are specially designed for fast movements and maximum control accuracy.
With the EcoPower Xpress, injection speeds of up to 650 mm/s and injection pressures of up to 2500 bar are within reach. These values are made possible by all-electric plasticizing units combined with a fast-responding encapsulated injection aggregate.
For the production of standardized closing caps, maximal mold speeds together with short strokes and optimal dosing performance must be achieved. The EcoPower Xpress fulfils all of these requirements with a reliable and safe production process, and with cycle times far below 2.5 seconds.
Moreover, the energy consumption rates are kept extremely low by the machine’s efficient servo-electric drive system.
Following demolding, the finished screw caps fall down onto a conveyor belt positioned below the machine’s mold space. The parts are then conveyed to an end-of-line automation system supplied by IMDvista.

Inside this system, the caps pass through the stations of cooling, orientation and separation, and finally inline quality inspection. Any faulty parts detected are automatically sorted out before the good parts reach the packaging station.
The total cycle time for making these 32 screw caps is no more than 2.5 seconds.
