Commonly used plastic materials include PET, PE, PP, PVC, etc. The traditional marking process on these materials has some shortcomings. The shortcomings of several traditional marking processes are described below.
- Printing or ink printing:
After the product is formed, the content to be marked is added to the surface of the product by printing or ink jetting, both of which are easy to dissolve and volatilize by attaching chemical substances to the product, causing damage to the product and the environment. Pollution. Ink text or graphics are easy to wear and tear, and are easily blurred by moisture, which affects consumers’ identification.
- Injection molding:
The text or graphics to be identified are designed on the injection mold, and the text or graphics are formed together with the product. The fonts or graphics are the same color as the product itself, without contrast, making it difficult to identify. The cost of mold making is high, and each mold can only correspond to a fixed content, which cannot be molded and changed, and the flexibility is poor.
In order to solve the problems of poor marking effect on plastic materials, high raw material cost and low marking efficiency in the prior art, the plastic laser marking machine developed by Dowin Laser came into being.
Process advantage:
- 1.The self-owned brand digital high-speed scanning galvanometer is used to mark fine markings with no bumps, no explosion points, no sawtooth, and clear edges.
- 2.High beam quality, small focusing spot, ultra-fine marking and high definition.
- 3. The heat-affected area is small, the surface of the plastic shell is not damaged, the color is uniform, and the effect is good.
