The present invention provides a kind of processing methods of radiating fin, as shown in Figure 1, including the following steps:
Molding process 100 is provided:
A kind of stamping die is provided, the mold includes upper die and lower die.
Laser treatment step 300:
According to preset pattern, lines drafting is carried out to the lower die using radium-shine processing technology, on the surface of the lower die
Make preset pattern.
Wherein, specifically, in one embodiment, the laser treatment step 300 includes:
Read the draw data of preset pattern；
The face to be processed for scanning the lower die acquires the image data in the face to be processed of lower die；
The image data of the draw data of preset pattern and the face to be processed of lower die is compared, determines radium-shine processing
Drawn path；
According to drawn path, radium-shine processing is carried out to the lower die, makes preset pattern on the surface of the lower die.
For example, the mechanism for carrying out laser treatment is connected with control system, wherein the draw data savings are in described
In control system, lift wherein preset draw data, which is the forming shape that finished product need to make.By under scanning
The face to be processed of mould acquires the image data in the face to be processed of lower die, for example, by CCD camera acquire image, lower die it is to be added
