Abstract
The invention relates to the technical field of molding process, and in particular relates to a one-step molding process of a silicone wristband. The one-step molding process of the silicone wristband comprises the following steps: step 1, placing an intelligent component in a mold; step 2, injecting a silicone raw material into the mold; step 3, molding by vulcanization; the silicone raw material has self-adhesive property when being combined with the intelligent component. Since the intelligent component in placed in a cavity of the mold and the silicone raw material which has self-adhesive property when being combined with the intelligent component is injected into the cavity to be molded by vulcanization, the intelligent component can be adhered with the silicone firmly so as to avoid the process for coating the intelligent component with glue in the prior art; therefore, the production process is greatly reduced and the production time is shorten, and thus the production difficulty and cost are reduced, and the production efficiency is improved.
