Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] See attached figure 1 , a production process of a shielding cover for electronic products, comprising the following steps:

[0037] S1. Base material pretreatment to obtain the required metal strip. In actual production, the base material used can be SPCC cold-rolled steel strip or stainless steel strip. During the pretreatment process of the base material, the staff can first use the calender to perform rolling treatment on the base material steel strip, and roll the steel strip to the required thickness. Subsequently, the staff can use the steel strip slitting machine to cut the steel strip into the required width specifications, and form the required metal strips; in actual work, the commonly used widths of the metal strips are 30mm, 50mm and 100mm. After the steel strip is cut, the staff can clean the surface of the steel strip with a cl...

Abstract

The invention discloses a production process of a shielding cover for electronic products, and relates to the technical field of electromagnetic shielding. The production process comprises the steps of base metal preprocessing, coating printing, baking, cooling and the like; in the baking process, the baking temperature is 180-220 DEG C and the baking time length is 3-5 min; from the beginning tothe end, the baking process comprises four stages in sequence: a first intermediate temperature stage, a high temperature stage, a second intermediate temperature stage and a secondary high temperature stage; and a baking temperature difference between any two adjacent stages is at least 10 DEG C. The production process of the shielding cover for electronic products is not only capable of improving the using performance of the metal shielding cover and prolonging the service life of the metal shielding cover, but also beneficial for improving the production efficiency and the product outgoingquality.

Description

technical field [0001] The invention relates to the technical field of electromagnetic shielding, in particular to a production process of a shielding case for electronic products. Background technique [0002] The shielding cover is a tool used to shield electronic signals. It can effectively shield the influence of external electromagnetic waves on the internal circuit and the external radiation of electromagnetic waves generated inside. It is mainly used in electronic products such as mobile phones, GPS, and computers. [0003] The existing patent application publication number is CN107302842A. The invention patent application discloses a metal shielding cover single type insulating paint printing method and a metal shielding cover single structure. First, the shielding cover is punched out on a metal strip, and then the shielding cover Brush the cover with insulating paint. [0004] When the above-mentioned technical solution is used for the production of metal shields,...
