Incoe Europe Minimum cavity spacing allows for optimum injection moulding
Europe – Minimum cavity spacing is indispensable for efficient injection moulding using multi-cavity moulds.
Incoe says this has been achieved with its screw-fit nozzles, DFQ 5 plus slim base heater nozzle series, that were presented at Fakuma 2015. DFQ 5 is said to reduce the minimum cavity space from previously 22 to 18 mm and as such is on par with the glide-mounted nozzles in use today to provide the user with practically unlimited benefits of screw-fit nozzles.
Incoe notes that the injection moulder can cut costs as there is no longer a need for a retainer plate to support the nozzle heads, nor for clamping connections between nozzles and manifolds. Also eliminated are elements to prevent plate sag. Operating costs are lower as there are no contact surfaces in the mould between nozzles and manifolds, thereby preventing heat losses in the mould. Moreover, the form-fitting connection is said to provide good operational reliability. There are also no leaks between nozzles and manifolds which can be caused by a reduction in pressing force in the network of mould plates, bolts and support elements.
For stability and production reliability, the nozzle flange has remained unchanged, providing an improvement in temperature control. When a large number of mould cavities and open nozzles are involved, optimum temperature is crucial for an even filling as well as a clean separation at the point of demoulding.
