Energy-efficient injection moulding

Energy-efficient injection moulding

In a special show at the Fakuma 2011, material producer BASF and machine manufacturer Arburg will present the multi-faceted subject of energy efficiency. Visitors to the East Foyer will be shown measures for increasing energy efficiency in injection moulding throughout the entire value-added chain and beyond, thereby reducing unit costs. Using a specially-optimised plastic and the appropriate machine technology, the two companies will demonstrate how new developments can work together to save energy.

On a total exhibition area of 100 square metres, the entire injection moulding process will be analysed in detail in terms of energy-efficiency: from product design through to production planning. As a clear practical example, comparative production with two different plastics will show how energy efficiency can be enhanced by the right choice of material. For this purpose, an electric Arburg Allrounder 370 E will produce test parts from a standard plastic and from a material that was specially improved in terms of its flow characteristics. The “energy measurement” function of the Selogica machine control system registers the energy requirement of the relevant process.

The comparison makes clear how an energy-optimised machine, together with a plastic with improved flow characteristics, can contribute to significant energy savings in the injection moulding process. Depending on the size of the components and their geometry, the lower processing temperatures and shorter cycle times result in greater energy efficiency, plastic injection mold maker
thus reducing unit costs.

Improved flow properties can be exploited in a variety of ways. Delicate structures and thin-walled parts can be filled more easily and reliably, leading to a drop in the reject rate, particularly in the case of complex geometries. The significantly-reduced injection pressure means that the moulds are subjected to much less wear. This increases operating times and reduces maintenance costs. Improved flow means that less injection and filling pressure is required for large components in particular, so that the locking force can be reduced, enabling processors to manufacture their products on smaller machines. In addition, fewer injection points or hot-runner nozzles are required on moulds. Despite the thinner walls, it is even possible to produce components with a comparatively high glass-fibre content.
