For the launch on the European market, hot runner manufacturer Incoe presents the new Sealfit Hot Halves at K 2019. A Sealfit Hot Half includes a ready-to-go pre-assembled hot runner system with Sealfit nozzles which has been installed and adjusted inside the related mould plates and which has been pre-tested for functionality before leaving manufacturing.
Sealfit means: All nozzles are screwed into the manifold producing a leak-proof connection between nozzles and manifold. By offering the related mould plates with the runner system in Europe Incoe is enhancing the concept of supplying ready-made modules and following a request from the multi-cavity market where hot runner systems with Sealfit nozzles have been successfully introduced.
Reduction of time and effort needed for project planning and management, design, manufacturing and assembly, a simplified start of production and increased production reliability are the main benefits of using Hot Halves. Furthermore, production reliability is increased by the Sealfit concept with all nozzles being screwed into the manifold producing a leak-proof connection between nozzles and manifold and resulting in a reliable alignment between the flow channels of the manifold and the nozzles irrespective of the material and the process. Due to the nozzles being screwed into the manifold there is no need to have nozzle heads sitting in special pockets which need to be machined on very tight tolerances into the mould plate. All work to achieve a leak-proof connection of all nozzles with the manifold by adjusting mould plates, nozzles heads and manifold in the mould is not needed anymore. Without nozzle head there is no contact between the nozzle and the mould at the interface between nozzle and manifold. Therefore no heat can flow into the mould plate and no forces are applied to the mould plate. This leads to a reduced consumption of energy about 20 %. The risk of deforming the mould plate is reduced — even when the temperature is increased. Wear at guide pins and other centering elements due to deformation of mould plates is also reduced.
The concept of supplying ready-to-go pre-assembled systems in “one piece” makes sure that maintenance and service are very user-friendly: As far as possible all supply lines and connections are mounted to the hot runner system so the hot runner system can be completely taken out of the mould plate in one step. The associated effort for assembly and disassembly of supply lines in specially made grooves in the mould plates is not needed anymore. In case of pneumatic valve gate systems the air supply lines can be drilled into the mould plate. For service the hot runner system is separated from the lines by lifting it up. When an Integrated hot runner is used most of the service can be done on the machine.
