explained that automotive remains the core market for the company but, in order to pursue growth, it is diversifying into other markets. It sees a market opportunity in pallets and other transportation packaging, as applications have similar moulding challenges to automotive components like bump- ers: they are large mouldings with both thick and thin wall areas. Callegari said HRSFlow’s expertise in automotive can be transferred to other areas like electronics and consumer products, such as the suitcase shown at Fakuma which had a wall thick- ness of only 1.8mm. Hasco has extended its product range of

including the elements needed for subsequent assembly. This structure is then overmoulded with a thermoplastic elastomer (TPV) in the opposite section of the mould. This produces the flexible visible surface with the fine grain that is later responsible for the high optical and tactile quality of the centre armrest.

With both injection moulding steps, a FlexFlow hot runner system is used, with two or three hot runner nozzles. Their servo-electric, individually controlled valve pins ensure optimum filling of the cavities in each case, and they also contribute to the reliability and economic viability of the process. The company says that the integrated servo-electric valve gate system opens up a variety of possibilities for adjusting the process parameters. For example, it is possible to control the individual pins of a hot runner system independently of one another with regard to their stroke, velocity and force. This means that users can control the pressures and flow rates during the entire mould-filling process accurately, easily and flexibly and thus optimise the quality of injection moulded parts. Advantages over conven- tional pneumatically or hydraulically driven valve gate systems include producing streak-free Class A surfaces and reducing warpage. Another benefit is its mainte- nance and user friendliness. The clamping force can be lowered by around 20% and the part weight by up to 5%, while ensuring high reproduc- ibility. At Fakuma, HRSFlow showed a number of non-automotive applications on its stand, including a PP-shell suitcase, a polycarbonate laptop cover and a PP and TPE two-component baby bath, all of which were moulded using FlexFlow hot runners.

ready-to-install single needle valves with the H44201 and H44202 hot halves, which the com- pany says offer high efficiency and system safety. The entire needle shut-off unit is installed directly and mould-sized, making it easy to maintain and is designed and produced for the application. The hot half is ready for immediate use: it is equipped with Vario Shot nozzles, all hot runner and connec- tion components, the clamping, frame and nozzle retainer plate, and all standard parts. The ready-to- connect system is simply attached to the fixed mould plate. After connecting the system to the peripheral control and supply units, production can begin. Hasco adds that the concept of the hot half allows mould makers and injection moulders to reduce their design and manufacturing times significantly. The hot half is designed to the customer’s specifications and within days supplies the CAD data in the required format. Hasco has also extended its hot runner product

portfolio with the H1280 series of control units. This controller has high functionality and comprehensive diagnostics, says the company. Three housing sizes with 6-36 zones are available as table-top units. With a new intuitive touch user interface, the controller is easy to operate. Operating functions allow data to be entered at different navigation levels. The Quick Start assistant guides users through all the key settings and enables untrained personnel to safely commis- sion the controller within a short time. The functions offered by the hot runner con- troller include comprehensive monitoring to protect the controller, hot runner system and mould. One feature is a

troubleshooting agent, which enables the cause of a malfunction
