W837 in-mold labeling system from WITTMANN. |
The completely new IML (in-mold labeling) system by WITTMANN was unveiled during the K 2016 exhibition that took place in Düsseldorf, Germany, last October. W837 production cell is designed for decorative lid production with camera control. The new smart system was displayed jointly with a new EcoPower Xpress IMM designed by WITTMANN BATTENFELD
W837 IML is one of the creative thought peaks for WITTMANN lately. The entire IML equipment range by WITTMANN is currently being steadily optimized with an eye on equipment size, production reliability and flexibility, and reduction of power requirements.
The system profile is based on extensive R&D experience of WITTMANN. It allows for taking into account all the required factors, which is critical for cost-effective practice of manufacture.

The base ingredient in the W837 IML system is a highly dynamic horizontal axis, allowing for the quickest insertion/removal and the most accurate movement control. Moreover, raw material is handled and finished items deposited in a new way, in order to reduce equipment size. W837 IML systems boast increased productivity and optimized power use, making a sizeable contribution to sustainability implementation in the field of plastic processing.
The system demonstrated at K 2016 was shown alongside an EcoPower Xpress 400/1000+ IMM from WITTMANN BATTENFELD. PP lids were produced in the manufacture cell with a 4.7 s cycle time in an eight-cavity mold designed by Greiner Packaging, Austria. W837 system both inserted IML foils into the mold and took out the finished lids.
The new IML system makes it possible to increase the speed of part delivery onto a synchronized conveyor belt. Finished parts are perfectly aligned and go through the camera station, integrated in the system. The station inspects every lid thoroughly: label positioning and decoration are checked. Reject is further conveyed and dropped in a dedicated bin, while good parts are stacked.
Items picked for quality control routine may be ejected from the producing cell at any moment needed via a dedicated outlet.
The system is equipped with very high-performance servo drives, enabling the most dynamic movements to be ideally coordinated. On the one hand, this shortens run-in and production cycle times considerably, and on the other, reduces power consumption drastically. Finally yet importantly, the IML system has an integrated vacuum pump system, reducing the whole system requirement for compressed air to several liters per minute only.
The new in-mold labeling system allows for the manufacture of lids with different dimensions. Machine readjustment for these purposes is very simple and easily made by hand.
