Formable inserts and related methods

A method of forming a cover with a formable insert, the method comprising:

• forming a first frame composed of a first material, the first frame having a first dimensional height that is less than a respective dimensional height of the cover, wherein the first frame defines an opening to receive a feature of a mobile device;
• applying heat to the formable insert to form the formable insert to a shape of the first frame;
• applying the formable insert to the first frame such that a foldable portion of the formable insert protrudes from respective perimeter edges of the first frame;
• positioning the formable insert and the first frame in a mold tool;
• folding the foldable portion of the formable insert relative to respective perimeter edges of the first frame such that the perimeter edges of the formable insert are oriented toward an inner surface of the first frame;
• and
• injecting a second material adjacent the folded portion of the formable insert to capture the perimeter edges of the formable insert in the second material, wherein a volume of the injected second material is smaller than a volume of the first material that forms the first frame.
