The present invention, which implements, will not enumerate.
First rupture pressure disc of predetermined size is bonded in the mould by step 102, will be described default by transfer printing process
The corresponding texture of optical texture is transferred on first rupture pressure disc, to form the second rupture pressure disc with texture face.
Sheet material made of first rupture pressure disc of the predetermined size can be cut by explosion-proof film coiled material.
Wherein, explosion-proof film coiled material can be 25 μ by the polyethylene terephthalate (PET) and thickness that thickness is 50 μ
Optical cement OCA (OCA) glue-line made of.
The predetermined size can be long 300MM, width 400MM.Certainly, which can also be other numerical value, this hair
Bright embodiment does not limit specifically, and when specific implementation can set according to actual demand.
In this step, which may be used existing transfer printing process.
Step 103, by optical coating technique, be coated with electroplated layer on the texture face of second rupture pressure disc, with formed
Third rupture pressure disc.
In this step, which may be used existing optical coating technique.
Wherein, the environment of the optical coating technique needs to reach thousand grades of cleanings.
Step 104, by silk-screen printing technique, face where the electroplated layer of the third rupture pressure disc is printed to pre-color
Ink layer, to form the 4th rupture pressure disc.
In this step, which may be used existing silk-screen printing technique.
Wherein, the environment of the silk-screen printing technique needs to reach thousand grades of cleanings.
4th rupture pressure disc is placed in laser carving machine platform by step 105, carries out laser carving molding.
In this step, which may be used existing numerically-controlled machine tool (CNC) laser carving technique.
In embodiments of the present invention, by using the mold of preset optical structure so that the optical diaphragm prepared is presented
Go out multi-level optical texture, there is stereovision;Again by the way that the first rupture pressure disc of predetermined size to be fitted in the mold, pass through
The corresponding texture of preset optical structure is transferred on the first rupture pressure disc by transfer printing process, anti-to form second with texture face
Quick-fried film is coated with electroplated layer on the texture face of the second rupture pressure disc, to form third rupture pressure disc, is passed through by optical coating technique
Face where the electroplated layer of third rupture pressure disc is printed to the ink layer of pre-color by silk-screen printing technique, explosion-proof to form the 4th
4th rupture pressure disc is placed in laser carving machine platform by film, carries out laser carving molding so that the optical diaphragm gloss level prepared is rich
Rich nature and have color gradient effect, meets fashion, the appearance demand of trend of consumer's pursuit.
Optionally, as one embodiment, preset optical structure described in above-described embodiment may include:Bottom, light beam
Lamina and N layers of flash-point layer.Wherein,
The bottom is the crosslamination of default geometric figure, which can be lattice or dot or small
