Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with specific embodiments.

[0031] The specific embodiment of the present invention is a method for making a plastic metal bright edge, and the specific steps are as follows:

[0032] S1: Make a plastic case with a specified shape and size, and polish the front and back of the plastic case to a mirror effect;

[0033] S2: Spray a layer of UV primer with a thickness of 18-20 μm on the front of the plastic case, and then bake at a temperature of 50-70°C for 5-10 minutes, wherein the UV energy is controlled at 800-900 mJ / cm2;

[0034] S3: Spray a layer of metal paint with a thickness of 8-12 μm on the front of the plastic case obtained in S2, and then bake at a temperature of 70-75°C for 10 minutes;

[0035] S4: Spray a layer of 20-25 μm thick matte finish on the front of the plastic case obtained in S3, and then bake at 45-60°C for 5-10 minutes, wherein the UV energy is controlled at 1000-120...

Abstract

The invention discloses a manufacturing method of a plastic metallic bright side, comprising the following steps: manufacturing a plastic housing and polishing; spraying UV priming paint on the rightside of the plastic housing, spraying metallic paint, and finally spraying matt finish; removing baking varnish at specific positions on the right side of the plastic housing through a laser etching machine so as to obtain curved 3D pattern, and washing; spraying UV paint on the back side of the plastic housing, placing into a vacuum furnace, evaporating a plating material by heating through an evaporation source, and letting steam of the plating material be coagulated on the back side of the plastic housing so as to form a plating film; and finally spraying UV finish. The plastic housing manufactured by the method has strong metallic effects. The invention has the following effects: by NCVM polymer metal deposition deep at the plastic housing, the baking varnish with matte metallic texture attached and having microscopic high light texture is formed. Through the series of process, smoothness of holding hand feeling is enhanced, and the product is extremely close to the metallic texture.

Description

technical field [0001] The invention relates to the field of processing plastic and metal bright edges, in particular to a method for making plastic and metal bright edges. Background technique [0002] With the ever-changing needs of consumers, mobile phone manufacturers are constantly updating and upgrading the performance of mobile phones, and are also constantly making breakthroughs and innovations in product materials. [0003] In recent years, the materials of mobile phone casings have changed from polycarbonate to various alloy casings, to carbon fiber and glass casings, and even wooden and ceramic casings... From this series of evolutions, it is not difficult to see that consumers have a high demand for the quality of mobile phone casings. The requirements are getting stricter. In addition to the continuous exploration of new materials, mobile phone manufacturers have also been rediscovering traditional materials. [0004] As the most commonly used material for mob...
