Embodiment 1

[0029] According to the following method, an aluminum alloy plate metal part with a size of 100x100x2mm is molded with plastic.

[0030] Biting flowers on the aluminum alloy plate;

[0031] The aluminum alloy plate is heated to 120 degrees, and the hot melt adhesive (615ST product of 3M Company) is laminated on the aluminum alloy plate with a lamination roller, and the lamination time is 6 seconds. The thickness of the hot melt adhesive is 0.12mm.

[0032] Then put the aluminum alloy plate into the mold, under the temperature of 280 degrees Celsius, 1350kg / cm 2 Under pressure, the plastic raw material is injected onto the aluminum alloy plate.

[0033] Curing and forming. Product A is obtained.

Embodiment 2

[0035] According to the following method, an aluminum alloy plate-shaped metal part with a size of 50x50x2mm is molded with plastic.

[0036] Biting flowers on the aluminum alloy plate;

[0037] The aluminum alloy plate is heated to 120 degrees, and the hot melt adhesive (615ST product of 3M Company) is laminated on the aluminum alloy plate with a laminating roller. The lamination time is 6 seconds, and the thickness of the hot melt adhesive is 0.10mm.

[0038] Then put the aluminum alloy plate into the mold, under the temperature of 280 degrees Celsius, 1250kg / cm 2 Under pressure, the plastic raw material is injected onto the aluminum alloy plate.

[0039] Curing and forming. Product B is obtained.

Embodiment 3

[0041] According to the following method, an aluminum alloy plate metal part with a size of 100x100x2mm is molded with plastic.

[0042] The aluminum alloy plate is heated to 120 degrees, and the hot melt adhesive (615ST product of 3M Company) is laminated on the aluminum alloy plate with a lamination roller, and the lamination time is 6 seconds. The thickness of the hot melt adhesive is 0.12mm.

[0043] Then put the aluminum alloy plate into the mold, at a temperature of 285 degrees Celsius, 1350kg / cm 2 Under pressure, the plastic raw material is injected onto the aluminum alloy plate.

[0044] Curing and forming. Product C is obtained.

Abstract

The invention provides a forming method for manufacturing plastic products with metal pieces; the method comprises the following steps: a. an adhesive layer is arranged on the surface of the metal piece. b. plastic raw material and the metal piece are integrated into one body. The invention also provides a product manufactured by the method; by adopting the method, the plastics are formed while the metal piece and the plastics are integrated into one body, so as to lead the plastics and the metal piece to be adhered together by surface contact under a no buckling condition, that is, the plastics are not needed to be embedded in a metal structure, the metal structure is not needed to be embedded in a plastic structure; the structure of the metal piece is simplified, the mechanical processing difficulty in design is reduced, and the product quality is ensured at the same time.

Description

technical field [0001] The invention relates to a molding method, in particular to a molding method of a plastic product with metal parts. Background technique [0002] As a practical tool, electronic products must meet their quality requirements while meeting the requirements of communication and appearance. The lightness and thinness of electronic products will affect their strength, and they are prone to breakage after falling. In order to solve For strength issues, materials with high strength and moderate flexibility are generally selected. If the structural strength of the material itself is not enough, metal parts are generally added to ensure the product strength by means of insert molding or assembly of metal. [0003] For the design of large-area metal inserts, it is often necessary to punch holes in the metal sheet or add buckles, etc., the processing is complicated, the yield is not high, and the cost is high. At the same time, because the bonding strength of pl...
