Abstract
A method of forming an integral intermediate layer in a flexible single injection molded component is disclosed. According to the method a strip comprising the sandwiched layer is securely positioned within a molding cavity. During injection of the mold material a tensile force is applied throughout the strip in a plane orthogonal to a critical component direction. The method is particularly suited for the fabrication of wrist mounted electronic devices having an electrical connection to a conductive member integrally housed within a molded wristband.
Claims13
A method for injection-molding a wristband embedded antenna comprising the steps of:
- a. providing a flexible electrically conductive member having a removable tag projecting from one longitudinal end of said member and an end portion projecting from an opposite end of said member;
- b. forming a molding cavity from a pair of molds and further forming a gate, positioned on an inner wristband side, for injection of a molding material;
- c. securing said member within said molding cavity such that said member is nipped between said pair of molds;
- d. applying a tensile force to said member;
- e. injecting a molding material into said cavity concurrently with step d;
- f. releasing said tensile force following step e;
- and
- g. severing said tag from said conductive member inside the molded wristband after step f such that any unremoved tag portion remains unexposed at the wristband end.
