Problems solved by technology
[0004] 1. The shrapnel is not easy to place and it is easy to fall off in the mold
[0005] 2. During the secondary injection molding, the injection pressure will easily deform the buckle position of the primary molding
[0006] 3. Although the subsequent surface treatment is done, the appearance of the product does not have a metallic texture
[0007] 4. The waterproof performance is low, generally only up to 5M

The invention discloses a shell structure of a wristband and a manufacturing method of the shell structure. The shell structure comprises an aluminum metal main body with a box-shaped structure and a stainless steel resilient sheet which is connected with the aluminum metal main body through spot welding, wherein one end, which is in spot welding with the aluminum metal main body, of the stainless steel resilient sheet is located in the aluminum metal main body; the stainless steel resilient sheet extends out of the aluminum metal main body; a plastic structure part formed by injection molding covers an external part, located outside the aluminum metal main body, of the stainless steel resilient sheet. By adopting the shell structure disclosed by the invention, the defects and disadvantages in the aspects of waterproof properties and appearance of a wristband shell of a traditional scheme are effectively solved; the structure is more stable and reliable and is convenient to manufacture and high in yield.
Description
technical field [0001] The invention relates to a shell structure of a bracelet and a manufacturing method thereof. Background technique [0002] Today's smart wearable wristband market is becoming more and more fierce. In order to meet and attract customers' needs, powerful functions and exquisite appearance are customers' first choice. In order to meet the requirements of product functions and appearance, the structure and process of products need to be constantly updated. [0003] The traditional process of the main body of the smart wearable bracelet shell is to directly put the stainless steel shrapnel into the mold for injection molding. Specifically, put the stainless steel shrapnel 2 into the plastic mold for the first in-mold injection molding to form the first injection molding Part 3, put the components that have undergone the first injection molding into the second molding mold for the second injection molding to form the plastic shell 1, such as figure 1 shown....
