Wittmann Battenfeld brings ‘smart’ vertical rotary table to K

Wittmann Battenfeld (Kottingbrunn, Austria), a member of the Wittmann Group and a global provider of injection molding machines, robots and peripheral equipment for the plastics industry, will showcase its new, vertical rotary table with a C frame design in combination with the new unilog B8 control system at K 2016 next week in Düsseldorf, Germany. The company is exhibiting at booth D22 in hall 16.

Vertical machine technology with open access to the mold space from all sides has been a key to market success for many years, noted Wittmann Battenfeld in its announcement. The rotary tables are available with clamping forces ranging from 400 to 2,700 kN and in diameters from 752 to 1,755 mm. The insertion and removal area can be protected by light screens, thus providing optimal conditions for parts removal and implementing automation concepts. In this way, the machine series is ideally suited for both manual and automated removal processes.

The vertical rotary table is currently available with 400 and 800 kN clamping forces; both the barrier-free clamping unit and servo-controlled injection unit are placed in a vertical position. The vertical C frame configuration with two symmetrical clamping cylinders maximizes free space in the mold area.

The new CM series is equipped with a ServoPower drive as standard. This also makes the machines from the new CM series operate with extreme energy efficiency, low noise levels and high precision. The machines can be supplied as purely vertical machines, in sliding table models or with a rotary table. Depending on the requirements profile, the rotary table machines can be supplied in two different sizes. The CM 40 with 400-kN clamping force is available as a compact rotary table model with a diameter of 752 mm, or as a generously dimensioned variant with a rotary table diameter of 1280 mm. The CM 80 with 800-kN clamping force can be equipped with a rotary table in diameters of either 1280 or 1520 mm.

At the K, the functionality of the new CM series will be demonstrated by a CM 20/210 R12980. On this machine, a connector housing made of PBT will be insert molded using a two-cavity mold. The machine is equipped with an automated insertion and parts removal system. A W821 robot from Wittmann places the inserts into the mold, removes the finished parts and transports them to the Wittmann W818 robot. This second robot picks them up with the help of a camera system and deposits them on trays.
