One-piece forming technique for metallic mobile phone key

Abstract

The invention relates to a one-time forming technology process of a metal mobile telephone key-press, including a steps of the film preshaping, wherein the film is arranged with a mounting position, one side of the film is printed with a printing ink for providing the metal key-press with different colors; a step of the metal key-press preshaping, wherein the back of the metal key-press is printed with hot melt adhesive; a step of sulfuration shaping, wherein silica gel is arranged on the die core of the upper die, and the film and the metal key-press are arranged between the upper die and the lower die in turn, the silica gel, the film and the metal key-press are one-time formed according to the given sulfuration shaping parameters. The technology process of the invention shapes the filmfor providing different colors to the metal key-press and the colloid for providing the flexible supporting on the metal key-press through using the upper die and the lower die in the vulcanizer, which simplifies the technology of the metal key-press shaping, reaches the key-press manufacture yield rate, saves the cost.

Description

【Technical field】 [0001] The invention relates to a forming process method of a mobile phone key, in particular to a one-time forming process method of a metal mobile phone key. 【Background technique】 [0002] In the case of increasingly fierce competition in the communication market, it is necessary to continuously introduce novel mobile phone design concepts to meet the needs of consumers. The mobile phone buttons that use metal that can bring texture as materials have gradually replaced the original plastic button design. At present, the molding method of mobile phone buttons is mostly secondary molding, which is divided into two types. The first is to use plastic sheet and liquid silica gel to make a silicone matrix, and then use a double-sided adhesive to bond the silicone matrix to the metal key through a jig. The second type is a combination of silicone and plastic buttons, that is, P+R buttons. The process is to make plastic buttons by injection molding first, the...
