Problems solved by technology

[0003] Bonding with glue has the following problems, the bonding force is not high, and the combination of metal and plastic is affected by the operator, working temperature and the quality of the glue. At the same time, the labor intensity of the operator is increased, and the product defect rate is high. At the same time The toxicity of glue endangers the health of operators
[0004] The metal and plastic are bonded together through the hot-melt process. Although the bonding strength is higher than that directly pasted by glue, it is greatly affected by the ambient temperature, and it is easy to fail to weld due to insufficient temperature. At the same time, for different materials, the temperature and pressure , time, etc. are difficult to grasp, and generally only experienced operators can master it well

Embodiment Construction

[0026] The in-mold forming method of appearance hardware provided by the invention makes metal and plastic integrally formed, which not only has the appearance and texture of metal, but also simplifies the design of product mechanism components, making the product lighter, thinner and smaller, with enhanced bonding force and reduced The follow-up effect is improved and the cost is reduced.

[0027] In order to enable those skilled in the art to fully understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0028] see figure 1 , is a schematic flow chart of the in-mold forming method for exterior hardware provided by the present invention.

[0029] The in-mold forming method of appearance hardware provided by the present invention comprises the following steps:

[0030] Step 01, providing a metal plate;

[0031] Step 02, performing chemical pickling on the metal plate to form nanoscale interlaced...

Abstract

The invention discloses an in-mold forming method of outer hardware, which comprises the following steps: providing a metal plate, carrying out chemical acid cleaning on the metal plate to form nano staggered pores on the surface of the metal plate, soaking the metal plate with staggered pores in an antioxidant, putting the metal plate soaked in the antioxidant into a mold of an injection molding machine, heating the mold until the temperature of the metal plate reaches 200-400 DEG C, injecting molten plastic into the metal plate, and cooling to solidify. The invention can integrate the metal and plastic, effectively reduce the thickness of the electronic product, simplify the element design of the product and enhance the binding force, thereby reducing the subsequent operation and lowering the production cost.

Description

technical field [0001] The invention relates to the technical field of shell production of electronic products, in particular to an in-mold forming method for appearance hardware with stronger bonding force between metal and plastic and integral molding of metal and plastic. Background technique [0002] The shells of mobile phones, e-books, digital cameras and other electronic products are usually made of metal, plastic, or metal and plastic. At present, the methods of combining metal and plastic are mainly pasting and hot-melt methods. on metal components. [0003] Bonding with glue has the following problems, the bonding force is not high, and the combination of metal and plastic is affected by the operator, working temperature and the quality of the glue. At the same time, the labor intensity of the operator is increased, and the product defect rate is high. At the same time The toxicity of glue endangers the health of operators. [0004] The metal and plastic are bond...
