CX Series with Optimized Drive Concept
A Boost for Productivity
In many cases a significant increase in productivity in injection molding can no longer be achieved purely by the isolated consideration or optimization of individual components. A systematized evaluation of the whole production cell is generally required. Taking the example of small and medium-sized injection molding machines, KraussMaffei Technologies GmbH, Munich, Germany, will be demonstrating how productivity can be boosted through intelligent solutions for plastication, control and automation.
The focus here is on applications for the hydraulic CX series and the all-electric AX SilcoSet for the processing of liquid silicone. The drive concept of the new CX has been energy-optimized so that thanks to intelligent accumulator management alone, the machine already requires 10 % less electricity (Fig.). Further significant savings potentials are offered by the new APC (adaptive process control) function that allows rapid restarting of the injection molding machine and with which even difficult material charges and charges with high reclaim contents can be processed to produce high-quality finished parts.
The Munich-based company will be demonstrating its FiberForm process that combines injection molding with the thermoforming of organic sheets on a CX 300 machine. The production of an airbag housing with cycle times of 42 s serves here as an example of series production-compatible lightweight construction using fiber-reinforced thermoplastics. This offers a weight saving of around 40 % compared to conventional metal parts. During the process, thermoplastic matrix-impregnated woven or bonded fabrics of continuous fibers are heated, formed in the injection mold (partner: Christian Karl Siebenwurst GmbH & Co. KG, Dietfurt, Germany) and then back-injected.
Silicones, whether liquid silicone rubber (LSR) or high-temperature vulcanizing silicones (HTV), are on the advance. Medical technology, the automotive industry and the leisure industry, in particular, are showing an increasing interest in the outstanding physical and chemical properties of the material. With the production of a nasal respirator unit of liquid silicone, KraussMaffei demonstrates that the manufacture of silicone products in medical technology makes high demands on the machine engineering. The application runs in a four-cavity mold on an all-electric AX with 500 kN mold clamping force. The metering and mixing unit from Elmet Elastomere Produktions- und Dienstleistung GmbH, Oftering, Austria, ensures optimum discharge of the residues and hence complete utilization of the material. The AX SilcoSet is suitable for use in clean rooms and has medical application approval.
