IMTEC®

The hybrid solution

IMTEC® is used for forming, particularly in injection molding (here in-molding technology). For the manufacture of plastics-metal components (hybrid parts), a system composed of injection molding machine, injection mold and optionally automation technology is required. The injection mould preferably made of steel consists of several components and different single parts. Only the core pins of the injection moulds have to be geometrically adapted to the IMTEC® molded inserts to achieve great accuracy and reproducibility.
The thread inserts are placed into the mold manually or by means of a handling system (figure 1, example of a plastic handle). Due to the forming process, the thread inserts are also sufficiently magnetized and can therefore be securely placed on magnetic core pins.
In the next step, the mould is closed (figure 2) and a precisely measured amount of the plasticized plastic material is injected into the cavities of the injection mould under high pressure and at high speed (figure 3). Until the liquid core of the molding material has cooled down and become solid, the component remains in the mold. After the end of the residual cooling time, the clamping unit opens the mold and the component is ejected (figure 4).
