New description: [New technical field], a metal workpiece with joint strength, especially a metal workpiece that can increase the joint strength of metal workpieces and plastic parts. [Prior Art] According to the development of electronic products, the design concept of light, thin, short and small is gradually becoming more and more, so that many electronic products (such as mobile phones, notebook computers, p D φ ' A) can be used by users. It is easy to carry. However, in order to make it easy for users to carry, most of these electronic products will reduce the weight of the product. The most common method is to cover the metal sheet with plastic parts as the outer shell of the product to reduce the overall weight and metal. In addition to protecting the product, sheet metal parts can be easily processed by electroplating, baking varnish, etc. Therefore, most electronic products are made of metal sheet metal, and the current plastic parts are mostly coated with metal sheet metal. The adhesive is applied to make the metal sheet metal adhere to the plastic part tightly. However, this method has the following defects and inconveniences: • (1) The volume of the adhesive is slightly reduced after hardening (partial liquid volatilization), It is easy to cause a gap between the metal sheet metal parts and the plastic parts, thereby reducing the yield of the finished product. (2) Due to the different expansion coefficients of the metal sheet metal parts and the plastic parts, the metal sheet metal parts and the plastic parts are easily separated due to heat expansion and contraction, resulting in damage to the outer casing, and the marketing channels of today's electronic products are spread all over the world. They are different, which makes such problems endless and causes inconvenience to users. (3) When metal sheet metal parts are combined with plastic parts, it is necessary to wait for the adhesive to harden, so that the processing time becomes longer, causing the boots on the production, and the adhesive required for the use of M368533 is lowered. This is higher, and the overall reading of electronic products is improved. The purchase of fine-grained users is intended to solve the problem of the problem of the problem, that is, the problem that the relevant actor wants to improve.
