Abstract
The invention relates to a molding treatment method of a plastic shell. The molding treatment method of the plastic shell is characterized by comprising the following steps: (1) injecting-molding the plastic shell with a transparent material, and engraving grains on an injection molding mold, so as to form a grain layer on the inner surface of the plastic shell; (2) spraying a color-enhancement paint on the inner surface of the plastic shell in a covering manner, so as to form a first color layer which only covers the grain layer on the inner surface, or spraying the color-enhancement paint on the overall inner surface of the plastic shell to form a first color layer on the inner surface; and (3) spraying a transparent protective top coat on the outer surface of the plastic shell. According to the molding treatment method of the plastic shell, the plastic shell can display a three-dimensional pattern effect, and the pattern is not easily abraded.
Description
Technical field
The present invention relates to a kind of forming processing method of plastic casing.
Background technology
Existing plastic casing outward appearance is single, and for forming three-dimensional pattern effect on housing, generally at housing outer surface depiction, but process can make outside unsmooth like this, and often use can cause wearing and tearing by pattern.
Summary of the invention
The object of the present invention is to provide a kind of forming processing method of plastic casing, the product of acquisition can present three-dimensional pattern effect and pattern is not easy to wear.
For achieving the above object, the present invention adopts following technical scheme:
A forming processing method for plastic casing, is characterized in that comprising the steps:
1) use plastic casing described in transparent material injection mo(u)lding, described injection mold is carved with texture, thus form texture layer at the inner surface of described plastic casing;
2) cover spraying to the inner surface of plastic casing add colored paint thus only cover the first color layers of texture layer in inner surface formation or the whole inner surface spraying of plastic casing is added to colored paint thus forms the first color layers at inner surface;
3) at the outer surface spraying transparent protecting paint of plastic casing.
As further improvement, in step 2) after increase following steps before step 3):
2a) cover the outer surface of plastic casing corresponding to texture layer, then externally surface spraying adds colored paint thus forms the second color layers at outer surface;
2b) carry out CNC Precision Machining removal step 2a at the edge of the second color layers) spraying produce when adding colored paint fly oil.
Further, described step 2b) in CNC Precision Machining adopt be MCD cutter.
Further, described step 2b) increase step 2c afterwards): at the transparent outer surface of filling the whole housing of paint covering of plastic casing outer surface spraying.
Step 2c described above) in the transparent refractive index of paint of filling close to the refractive index of transparent material.
Step 2c described above) in transparent fill paint refractive index be 1.5-1.53.
The refractive index of transparent protecting paint described above is close to the refractive index of transparent material.
The refractive index of transparent protecting paint described above is 1.45-1.48.
Transparent material described above is transparent PC or transparent PS or transparent ABS.
Advantage of the present invention is: 1, plastic casing presents three-dimensional pattern effect and pattern is not easy to wear.What produce when 2, adopting CNC Precision Machining to remove spraying additive color paint flies oil, makes neat in edge.3, adopt the refractive index of transparent filling paint close to the refractive index of transparent material, make product expression power exquisiter, have more artistry, sight.4, the present invention is simple to operate, technological process is few, cost is low.

Detailed description of the invention
A forming processing method for plastic casing, comprises the steps:
1) use plastic casing 11 described in transparent material injection mo(u)lding, described injection mold is carved with texture, thus form texture layer 12 at the inner surface of described plastic casing; Be illustrated in figure 1 completing steps 1) product structure schematic diagram.
2) the whole inner surface spraying of plastic casing is added to colored paint thus forms the first color layers 13 at inner surface;
2a) cover the outer surface of plastic casing corresponding to texture layer, then externally surface spraying adds colored paint thus forms the second color layers 14 at outer surface; As shown in Figure 2.
2b) carry out CNC Precision Machining removal step 2a at the edge of the second color layers) spraying produce when adding colored paint fly oil, machining sketch chart as shown in Figure 3; CNC adds man-hour can be about 0.1MM groove 18 at Working position Formation Depth, and product structure schematic diagram now as shown in Figure 4.
2c) spray transparent extend oil at plastic casing outer surface and form the outer surface that cover layer 15 paints the whole housing of covering.
3) protective layer 16 is formed at the outer surface spraying transparent protecting paint of plastic casing.
Described step 2b) in CNC Precision Machining adopt be MCD cutter 17.
Described step 2c) in the transparent refractive index of paint of filling close to the refractive index of transparent material, the refractive index of transparent filling paint is 1.5-1.53.
The refractive index of described transparent protecting paint is close to the refractive index of transparent material, and the refractive index of transparent protecting paint is 1.45-1.48.
Described transparent material is transparent PC or transparent PS or transparent ABS.
Above said content be only the present invention conceive under basic explanation, and according to any equivalent transformation that technical scheme of the present invention is done, all should protection scope of the present invention be belonged to.
