Wittmann Battenfeld is a world leader in all types of pneumatic and servo robots, featuring high speed operation and a robust proven design. With the advanced Teachbox R8.3 control system, custom end-of-arm tooling and full automation system integration capabilities, Wittmann Battenfeld has a robot for any application.
Wittmann Robots

Wittmann Battenfeld offers an entire range of robots for the flexible automation of injection molding machines – from small models, up to machines with very large clamping forces. Decades of application experience, innovative developments and more than 35,000 produced units have made the Wittmannrobots what they are today – the best robots for the plastics industry! Well planned detailed solutions and state-of-the art components allow highest reliability, shortest cycles and long intervals between maintenance.

BUS technology - All sensors/actuators at the robot are directly wired to the intelligent control card under the robot hood.

Demolding stroke (X-axis) - A large aluminum extrusion provides a stiff, vibration free foundation. The vertical arm is directly flanged on the cross tube. The linear bearings for horizontal stroke and demolding stroke are positioned in the main carriage next to each other to allow for high speed operation.

Powerful Servo Drive - Servo drives are used on all main axes

Horizontal stroke (Z-axis) - 95% of all robots are working using a rack and pinion drive. This is avoiding expansions of the drive belt when acceleration an decelaration are taking place. Optimal lubrication and life span of the drive system due to the pinion‘s placement within a grease cage.

Vertical stroke (Y-axis) - Rigid aluminum or steel extrusion depending on the dimensions of the units. Always driven via rack and pinion drive or drive belt, telescopic axes are driven by a combination of both.

Additional Rotational Axes (optional)

  •  A-Servo or pneumatic

  •  B-Servo 0–270° 

  •  C-Servo or Pneumatic

Wittmann Sprue Pickers and Primus Robots

The solid construction allows fast movement with low vibration for precise removal.

X-axis (kick-stroke)


  • Heavy-duty linear rails and recirculating ball bearings.

  • Swivel base to rotate the arm behind the fixed platen for mold changes and locating pin to precisely reposition arm for part removal.



Y-axis (vertical stroke) 0–550 mm (21.7“) or 700 mm (27.6")


  • Adjustable stroke.

  • Pneumatic shock absorbers.

  • Locking cylinder to prevent the arm from drifting down into the mold in the event of air pressure loss.

  • The Y-axis is also equipped with a heavy-duty switch as an additional interlock before the mold can close.

  • Energy chain for less wear of tubing.



Z-axis (pivot)


  • Freely adjustable from 45°–95°.

  • Simple changeover from rear side to operator side placement.



B-axis (90°C tooling rotation)
Rotation is made automatically when pivoting the Z-axis out of the press.

Mechanical Sprue Gripper.
With part monitoring.
