Degree reaches 15 ± 0.21GPa and is suitble to routine use.Using the suitable quickly production of laser carving or spraying, if if laser carving formation lines is hidden
Different effects is reflected under present light, sprays and is suitble to printing complicated and gorgeous pattern.
In the present embodiment, S06 shells, which are drawn a picture, draw a picture taking following steps using Freehandhand-drawing mode,
S061 modulates ceramic paint,
S062 is drawn to polishing enclosure interior face using art drawing or using outer picture handicraft picture to polishing hull outside face shape
At glazing shell,
Glazing shell is put into vacuum glaze firing stove by S063, and 1000~1200 DEG C are slowly heated up in 5~6h, rear to keep the temperature
1.5h, then temperature is slowly dropped to 900~800 DEG C in 2~3h, closes 10~12h of heating natural cooling.Using hand drawn picture,
The surface light refraction that the mobile phone shell of formation is formed is complicated.
Further include thering is rare earth oxide or transition metal oxide in ceramic powders in implementing this implementation technical solution
Toner.
The mobile phone shell color that conventional ceramic formula is produced is more single, and rare earth oxide or transition metal oxide is added
Carry out the color that coloring gives expression to the different periods of history.
Such as a kind of mobile phone shell made according to above-mentioned production method in Fig. 2~4, mobile phone shell includes to enclose shell 1, top screening
Baffle 2 and lower part shutter 3 enclose shell 1 to place cell phone mainboard and display board, and top shutter 2 is installed on enclosing shell
Body front upper portion, to fixed cell phone mainboard top, receiver and front camera, lower part shutter 3, which is installed on, is enclosing shell just
Face lower end, to the lower part of fixed cell phone mainboard.It is drawn a picture as shown in Figure 2,3 using enclosure interior face, as shown in Figure 4 outside shell
Portion draws a picture in face.
In addition the enclosure interior face pointed out in the present invention refers to enclosure interior bottom surface and enclosure interior side, hull outside face-piece
Bottom surface and hull outside side outside body.
The beneficial effects of the invention are as follows：
Compared with the prior art, by being preliminarily formed shell by biscuiting in the present invention, convenient for subsequently on lathe
Hull shape is processed out, is processed using ultrasonic wave CNC numerically-controlled machine tools, tool grinder headband has mill on ultrasonic wave CNC numerically-controlled machine tools
Grain, for the ceramic shell hardness that biscuiting goes out compared with praetersonic, ultrasonic wave drives the vibrations of abrasive grain high-frequency to process ceramic shell, more holds
Retrofit is easily carried out, reduces process equipment loss, drawing a picture in shell can draw a picture or the back side in the front of ceramic manual casing
It draws a picture, front, which draws a picture to show gorgeous patterned backside and draw a picture, can show indistinct pattern, and mode of drawing a picture includes can be with
For machine spraying engraving etc. or handwritten drawings, to mobile phone shell surface carry out processing increase hold affinity and reduce fingerprint or its
He retains grease type.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
