Wittmann Group launched much-awaited W822 robot model

The WITTMANN Group has launched its long awaited W822 robot model. The W822 will now serve as the entry model for small to mid-size plastics moulding operations that can involve significant degrees of complexity such as handling higher payload and carrying out mould insert work.  

The chief technical difference of the new W822 within the W82x series of robots is a rack and pinion drive for the vertical axis. The W822 can thereby handle 15 kg of payload on strokes of either 1,000 mm or 1,200 mm and 12 kg when fitted with the 1,400 mm axis option. In many other respects the W822 provides the same mechanical dimensions as the well-proven W821 model. A horizontal axis of up to 4,000 mm is possible and the W822 can be fitted with numerous automation features from the WITTMANN automation stable, such as servo rotational axes, spare I/O-modules and vacuum and gripper circuits.  

WITTMANN has developed and launched the W822 in response to moulder needs for greater payload and versatility around small to mid-sized moulding machines of up to 400 tonnes of clamping force. Thus far the entry level robot for insert application work has been the W832 robot. This model however has generally reckoned to be oversized on moulding machines of less than 200 tonne clamping force. The W822 robot now allows users a superior automation performance around the small and mid-size moulding machine range. 

The W822 comes as standard with the universal R8.2 robot control from WITTMANN. This includes real-time functions such as SmartRemoval, EcoMode, intelligent vacuum systems with teachable switchover levels, SoftTorque and many other advanced features. All related and attached downstream moulding operations can also be easily accessed through the R8.2 control for a single point of control.  

Martin Stammhammer, Sales Manager Robots and Automation Systems says that “the W822 robot is the latest in a comprehensive revamp of our WITTMANN automation range. Much of this work has been inspired by an increased customer need for more automation performance beside-the-press – increased payload, performance and flexibility. WITTMANN automation is enabling moulders of all kinds to be more ambitious in their production work – while at the same time resting secure in the knowledge that their robots have the capacity to handle increased payload and complexity. However equally important and the main focus of every design effort, is the easy access to all functions through the R8.2 control system.”
