High-speed machine series with IML application

23-Dec-08
At the Interplastica 2009 in Moscow from January 27 to 30, the Wittmann group will present itself to the Russian market with its new, powerful TM Xpress series, demonstrating an innovative in-mold labeling application and exhibits from its extensive range of peripheral equipment. In hall 8.1 / booth 39, PP cups will be manufactured on a TM Xpress 270/1350. Wittmann will also exhibit a W711 servo robot, temperature controllers with direct and indirect cooling, screenless granulators, a DRYMAX ES40 compact dryer and a GRAVIMAX 14R gravimetric metering unit. The production cell on display demonstrates a complete solution from the Wittmann group. On a TM Xpress 270/1350 with 270 ton clamping force, square cups (750 ml) will be manufactured from PP in a cycle time of just 4.7 sec. Insertion of butterfly labels as well as removal and depositing of the finished cups is handled by a Wittmann in-mold labeling device. The mold incorporated in the IML automation equipment comes from Wittmann's subsidiary in France, a mold maker specializing in this type of process. The TM Xpress, available with clamping forces ranging from 160 - 450 tons combines high speed with accuracy. This machine series offers the advantages of short footprint, precise platen parallelism and low-maintenance linear guides. The screw is driven by a geared servo motor incorporated in the center axis of the machine. In combination with a barrier compounding screw, this results in a highly energy-efficient drive with optimal homogeneity of the material processed. Extremely short cycle times are achieved through the additional option of parallel plasticizing. The machine concept provides ample space at the rear for utility connections. Also, cooling water, air and power supplies can be connected to both the fixed and the moving platen. The machine's high-performance hydraulic system guarantees the necessary high injection speed for thin-walled parts. High precision and excellent repeatability are achieved with fast-reacting servo valves fitted to the integrated hydraulic block.
