Abstract

See full text

A frame with an outer silicon layer and a manufacturing method of forming the silicone layer on the outer part of frame are disclosed. The manufacturing method includes a forming step, a combining step and a removing step. First, a pair of mold with a forming space is formed with a silicone carrier including an effective combination region and an ineffective region. An emplacing space is next formed in the effective combination region and a frame is put into the emplacing space. Before putting in the frame, either the outer part of frame or the emplacing space is coated with a silicone coating, and then the effective combination region is combined on the outer part of frame by a secondary sulfurization. Finally, the effective combination region is removed from the ineffective region to form a silicone layer, made of the effective combination region, on the outer part of frame.
