Soft rubber molding process for metal shell surface

Abstract

The invention relates to the field of machining process for metal shell surface protecting layers, in particular to a soft rubber molding process for a metal shell surface, which is characterized in that adhesives are coated on the metal shell surface, a soft rubber protecting layer is added to the outer side of the adhesives by means of soft rubber injection molding or silicon rubber heating vulcanization, and finally soft paint is coated on the obtained product. Besides, metal shells include notebook computers, tablet computers, mobile phones, articles for daily use and the like. The soft rubber molding process has the advantages that the metal shell surface is covered with the soft rubber protecting layer by the aid of soft rubber materials, compared with a metal part with appearance needing back-end processes of anodic treatment and / or painting and the like, the metal shell surface is low in cost, high in yield and simple, convenient in process and the like, the metal shell surface protecting layer of the manufactured product is more environment-friendly, soft in hand feeling and more attractive in appearance, the soft rubber and the metal shell surface are adhered by the adhesives so that the manufactured metal shell surface protecting layer is firmer and close, and the soft paint is coated on the outer side of the soft rubber so that the product is dirt-resistant, scratch-resistant and smoother in hand feeling.

Description

technical field [0001] The invention relates to the field of processing technology for the surface protection layer of a metal shell, in particular to a molding process of soft rubber on the surface of a metal shell, wherein the metal shell mainly refers to the shell of electronic equipment such as mobile phones, computers, and household appliances. Background technique [0002] Metal casings are widely used in notebooks, tablet computers, mobile phones and other consumer electronics and daily necessities. Due to the nature of metal itself, which is conductive and easy to oxidize, metal casings need to have a protective layer. The protective layer of the traditional metal casing is sprayed on the surface of the metal casing, which is relatively hard, not environmentally friendly, and the paint is easy to fall off. The protective layer of the existing metal casing also includes hard plastic, which has relatively poor heat dissipation. The aluminum (magnesium) alloy shells of...

Problems solved by technology

The protective layer of the traditional metal shell is sprayed on the paint on the surface of the metal shell, which is relatively hard, not environmentally friendly, and the paint is easy to fall off

The protective layer of the existing metal shell also includes hard plastic, which has poor heat dissipation

The aluminum (magnesium) alloy shells of Apple’s IPHONE, IPAD and other products are anodized, and the metal surface is used as the anode in the electrolyte. After the power is turned on, the metal is removed from the surface. The appearance is beautiful but the cost is high, and the process is not environmentally friendly.
