Temperature Control Technology Incoe Presents its New ‘Heat inject’ Solution for Optimizing Quality of Mould Parts

From Ahlam Rais

Germany – Incoe introduced its new ‘Heat-Inject’ product which makes use of hot runner systems for optimizing the quality of the mould parts and processes with the help of targeted heat pulses in the cavity.

Among the innovations that Incoe presented at Fakuma this year is the new ‘Heat-Inject’ product. It uses the hot runner system as a carrier platform, but instead of melt, it brings heat into the cavity. This is not an additional heater, but a movable tempering stamp, whose heated tip introduces a heat pulse thereby briefly pressing against the rear wall of the cavity, states the company.

This short local impulse can contribute in many ways to optimizing the quality of the moulded part and the process. According to the firm, weld lines and flow lines are still there, but no longer visibly appear on the surface, matt points no longer appear in the area of the gate, areas with low wall thickness, the cavity, such as in film hinges or thin-wall injection moulding, can be flowed through more easily, and delicate geometries and microstructures are easier to manufacture.

This innovative temperature control technology, based on the patent-pending Z-system from the firm’s partner Hotset, works extremely quickly with very low energy consumption. In doing so, it offers a technically relatively simple and robust solution for moulded parts with visually demanding surfaces, such as panels for household appliances, consumer electronics, or instrument panels in vehicles, adds the company.

The idea of assembling ‘Heat-Inject’ on hot runner systems has its origins in the concept of pre-assembled modules. The idea here is to offer customers components for their injection moulds that are already assembled into ready-to-use and ready-to-plug-in modules, thus saving effort and time during tuning and installation.

Of course, the tempering stamp still has to be inked and adjusted in the mould to ensure optimum heat transfer. But the fact that all Heat-Inject connections are combined on the central connection plate of the hot runner system, for example, eliminates the need for time-consuming installing and connecting of individual cables or hoses in the mould - everything is already mounted in a module and can be inserted in the sense of ‘plug and produce’ after all adjustment actions have taken place, mentions the firm.
