Wittmann Battenfeld at the Plastpol in Kielce

Wittmann Battenfeld at the…

At the Plastpol taking place from 24 to 27 May, Wittmann Battenfeld Polska will present to interested trade visitors ultra-modern injection molding systems as well as state-of-the-art robots and auxiliary appliances at booth No. F11 in hall F.

For many years, the Wittmann Group has been active in Poland, an important market for the company. Since the beginning of 2016, it has been operating its own sales and service subsidiary there as well. Together with its subsidiary Wittmann Battenfeld Polska, the Wittmann Group will demonstrate its latest developments to visitors of the Plastpol.

At this year’s Plastpol, the main focus in the area of machinery lies on showing fully integrated injection molding cells. For example, the exhibits will include a machine from the all-electric  EcoPower series with Wittmann 4.0 integration, as well as a servo-hydraulic machine from the SmartPower series in Ingrinder version. One outstanding feature of both these machines is their extremely high energy efficiency achieved by latest servo drive technology.

Complete integration with EcoPower 55 production cell

Wittmann Battenfeld will demonstrate its digitization expertise with the production of a medical part with an EcoPower 55/350, equipped with the software packages HiQ Flow for compensating viscosity fluctuations, HiQ Melt for material quality monitoring and HiQ Metering for active closing of the check valve.

Equipment integrated in the machine’s Unilog B8 control system via Wittmann 4.0 will include a Wittmann W918 robot, a gravimetric dosing unit Gravimax 14, an Aton plus 70 segmented wheel dryer and three temperature controllers from the Tempro plus D series, as well as the Temi+ MES system. The web browser included in the Unilog B8 control system also provides access to the Temi+ MES system. The production cell interlinked by Wittmann 4.0 supports electronic mold data sheets, and is thus able to check whether the auxiliary appliances connected to it are sufficient for the selected product data set, or whether additional equipment is needed.

The automation system is implemented via an Easy Cell developed and manufactured by Wittmann Battenfeld Deutschland in Nuremberg. The Easy Cell requires no safety gate and thus takes up only a minimal amount of space beside the injection molding machine. In spite of its compact design, customers receive the complete range of CE-compliant safety features.

Ingrinder

The Ingrinder is an injection molding system with integrated sprue picker, granulator and vacuum conveyor. The granulator and the sprue picker can be operated via the machine’s UNILOG B8 control system. The Ingrinder solution is designed for smaller injection molding machine models from the EcoPower and SmartPower series, since these machines are used in particular together with molds incorporating cold runner technology, thus producing sprue which must either be scrapped or passed on to a recycling system following injection molding.

At the Plastpol a can with a lid is produced from PS on a SmartPower 60/210 with a 2-2-cavity mold. A WP50 sprue picker from Wittmann with swivel drive removes the sprue and passes it to the G-Max granulator integrated in the system. The material recycled by the granulator is then transported to the machine’s material hopper by a Feedmax S 3-net vacuum conveyor. The Wittmann vacuum conveyors equipped with an optional material separator enable alternating conveyance of virgin material and regrind, so that a thorough blend is created by this process, together with discharge of the material into the hopper.

To equalize viscosity fluctuations caused by the recycled material, the Wittmann Battenfeld HiQ Flow software package is used on the machine. With HiQ Flow, viscosity fluctuations detected during the injection phase are actively corrected directly within the same shot.
