Efficiency for mold making and injection molding

The new SealFit™ Hot Halves offer reliable and user-friendly operation


For the launch of 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 fully adjusted inside the related mold plates and which has been pre-tested for functionality before leaving manufacturing. So a SealFit™ Hot Half represents a ready-made and tested pre-stage to complete half of a hot runner mold consisting of perfectly matched components - saving time and effort for the mold maker and increasing reliability during operation for the injection molder. SealFit™ means: All nozzles are screwed into the manifold producing a leak-proof connection between nozzles and manifold. By offering the related mold 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 that need to be machined on very tight tolerances into the mold plate. All work to achieve a leak-proof connection of all nozzles with the manifold by adjusting mold plates, nozzles heads and manifold in the mold is not needed anymore. Without the nozzle head, there is no contact between the nozzle and the mold at the interface between the nozzle and manifold. Therefore no heat can flow into the mold plate and no forces are applied to the mold plate. This leads to reduced consumption of energy by about 20%. The risk of deforming the mold plate is reduced – even when the temperature is increased. Wear at guide pins and other centering elements due to the deformation of mold 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 mold plate in one step. The associated effort for assembly and disassembly of supply lines in specially made grooves in the mold plates is not needed anymore. In the case of pneumatic valve gate systems, the air supply lines can be drilled into the mold 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.


The new SealFit™ Hot Halves made for efficiency for mold making and injection molding offer reliable and user-friendly operation

“Unplug and service”: The hot runner system including the attached supply lines can be taken out of the SealFit™ Hot Half and can be serviced on the workbench.

SealFit™ Hot Halves as ready-made modules follow the idea to save time and effort needed for project planning and management, design, manufacturing, and assembly
