At the Fakuma 2018, WITTMANN BATTENFELD is exhibiting for the first time its newly designed vertical machine to an expert public at booth No. 1204 in hall B1. The new VPower will be available on the market from the beginning of 2019.
With the new VPower, the proven vertical machine from WITTMANN BATTENFELD will now also be available in PowerSeries design. The PowerSeries is a market-leading machine series with numerous special advantages. These include its high energy efficiency already in the standard versions. Moreover, this series stands out by its high precision, compactness and user-friendliness. All of these attributes are also characteristic features of the new VPower. As a first step, this machine will be offered in the clamping force sizes of 120 and 160 t. As is the case with all PowerSeries products, its B8 control system with Windows 10 IoT and the integration facilities with WITTMANN 4.0 provide the basis for safe, easy integration inside a production cell and for corporate networking.
The basic feature of the new VPower is its innovative 2-tie-bar rotary table concept, which provides optimal accessibility by dispensing with the central tie-bar. The generously dimensioned rotary tables are combined with a 2-tie-bar portal clamping unit equipped with two travel cylinders on the outside for fast opening and closing. At the first stage, the rotary tables are available with diameters of 1,300 and 1,600 mm as well as with servo-electric drives for short rotation times and highly accurate positioning. They are laid out for both oscillating 2-station operation and rotary 2-, 3- or 4-station operation. Maximum operational safety is ensured by central greasing of all moving parts and sealing to prevent penetration of liquids or particles.
The tie-bar-less rotation center leaves ample space under the rotary table for cooling water, hydraulic oil, compressed air and power supply connections. These can be conducted to the molds through the center of the rotary table either via direct tubing or via an oscillating or rotary distributor. The new UNIFORCE compensation plate system between the horizontal beams of the clamping unit and the mold clamping area ensures even and gentle force transmission to the mold.
The injection unit can also be converted at a later date from vertical to horizontal or vice versa. Moreover, the drive unit of the VPower is equipped for operation with 2 aggregates. This means that the machine is also available as a 2-component model or can be retrofitted with a second aggregate later if the connection facilities for a second aggregate have been installed.
The VPower is equipped with a servo-hydraulic twin pump system as standard, which enables parallel movements of the opening and ejector strokes. Thanks to encapsulation and sound insulation of the motor and pump compartments, the drive unit is extremely silent. The highly effective fine filtration of the hydraulic oil in the main flow channel ensures the machine’s long-term high precision.
The machine’s open design makes it particularly well suited for the integration of automation systems with insert feeding and finished parts removal. Furthermore, it takes up considerably less space than its predecessor model, and its ergonomic, low working height of less than 1m is very convenient for its users.
At the Fakuma, the functionality of the new VPower will be demonstrated by a VPower 160/750 with a rotary table 1600 mm in diameter.
