In the process of making a prototype model, we will use a lot of processes. Today, we will talk about the laser engraving process used in the process of prototype processing. Some time ago, I came into contact with a customer who makes smart locks. He told me about the process of "in-mold printing". After communicating on the phone for a long time, I have no idea what this process is. The so-called separated lines are like mountains! After careful questioning and communication, I finally understand what it means, that is, if the product is a high-gloss surface, there are luminous things in it, there are words that are transparent, and other positions are opaque! Wow, I instantly understand that this wood injection molding can be realized by silk screen printing or laser engraving.

Laser engraving is generally used in the processing of transparent parts. First of all, we use transparent materials. After spraying paint, we go to laser engraving. Generally, logos, numbers, etc. need to be transparent. When we do not emit light, it is the same color as the product as a whole. If the luminous part is on, the part removed by the laser engraving will be transparent. Laser engraving is also long used in aluminum. The effect of aluminum laser engraving is generally faster than silk screen printing, and it will not fade. Generally, aluminum will choose laser engraving for logos that do not require color. There are still many processes in the process of making prototypes, which are different from the practice of molds. In fact, the process can be realized in another way.
