IMD VARIOFORM^®

3D geometries, four processes, one production step

KURZ won the Bavarian Innovation Award 2020 for this technological masterpiece. IMD VARIOFORM^® is particularly suitable for the production of components that become even more extraordinary with three-dimensional shaping thanks to sophisticated designs. In the same tool, a variety of single-image decors and endless designs can be applied. As a result, small series and individual equipment are economically feasible. To make desired design changes, only the IMD VARIOFORM^® substrate with decorative coating must be changed in the machine. Even PolyTC^® sensors can be integrated because they are very flexible due to their metal mesh structure. The combination of design and functionality ensures that your plastic elements with 3D geometry not only look spectacular, but also have integrated functional qualities.

Process: IMD VARIOFORM^®

For the production of three-dimensional plastic parts, the IMD VARIOFORM^® substrate with the desired decor runs through the machine as a wafer-thin coating in a roll-to-roll process. A thermoforming system as it is typical in conventional processes is not needed.
The IMD VARIOFORM^® coating is heated directly in the chamber of the injection mold and pressed into the cavity. This gives the plastic part its shape and its characteristic surface design with precise edges.
Subsequently, the blank can be relocated fully automatically in the injection mold and injected with thenecessary plastic material.
This step is followed by the use of a special tool technology called close-contour punching, so that the component receives its well-finished outer edges.

Decorating 3D plastic components with matching touch sensors in one step is pioneering. Bundling the four processes of decoration, thermoforming, injection molding, and punching is described in this use case.
