With the Z-System you selectively temper in the injection molding tool exactly in the place where the weld line would otherwise arise. The flow of plastic will be optimized on the problematic point. As a result, the plastics flow into each other and connect without visible weld line. We tailor the Z-System individually to your injection molding application and your mold.
You want to manufacture filigree injection molded parts with very thin wall thicknesses at selective points? The Z-System ensures that the plastic within the cavity penetrates even into the narrow, difficult-to-fill areas.
In order to realize partial optimization of the molding, the mold wall temperature must be increased. This can be achieved through the clever use of the Z-System.
In the injection molding process, a matt point has different causes. Among other things, small gates and high injection speeds play a key role. In the case of demanding design surfaces, you avoid matt points with the Z-System.
Functionally designed surfaces with fine microstructures require a high level of molding precision. This is conventionally achieved via high mold temperatures with longer cycle times – or via the Z-System with partial mold tempering and constant cycle times.
