Manufacturing method for a hanging structure of a hands-free mount

摘要

A manufacturing method for a hanging structure of a hands-free mount is disclosed. The hands-free mount includes a mount body and a hanging arm. The mount body is formed by a bottom shell and a top shell coupled mutually. The hanging arm includes a metal substrate and inner and outer coatings wrapping the metal substrate. The outer coating has a chamfered end located outside the bottom shell and inclined at an angle. The manufacturing method for the hanging structure of the hands-free mount uses an over-molding process to fully wrap the stainless steel core, so as to endow the hanging structure with good appearance and soft touch and prevent the product from rusting. Using the hanging structure as the hanging arm, the hands-free mount has improved firmness, appearance and touch.

主权项

1. A manufacturing method for a hanging structure of a hands-free mount, the method including:
an inserting step, wherein a to-be-wrapped stainless steel core that is preformed with a plurality of windows is placed into a forming mold, and the forming mold is closed such that the windows are exposed outside the forming mold; a positioning step, wherein polypropylene resin is injected to the forming mold so that the forming mold makes the polypropylene resin tightly attached to the to-be-wrapped stainless steel core; and a wrapping step, wherein thermoplastic elastomer is injected to fully wrap the to-be-wrapped stainless steel core with the polypropylene resin thereon; wherein the manufacturing method uses an over-molding process composed by the positioning step and the wrapping step to make the to-be-wrapped stainless steel core fully wrapped.
