Laser engraving method of plastic component

Abstract

The invention relates to a laser engraving method of a product, in particular to a plastic component laser engraving method for engraving any pattern or mark in an elastic workpiece with one layer being lucent. Laser engraving is carried out inside the plastic component at least comprising one layer of transmission material. The method comprises the following steps of starting a laser engraving machine; measuring the size of the plastic component to be engraved; editing the patterns and characters; calculating points of the patterns; calling in a picture file, selecting product dimensional specification and setting parameters; and carrying out the engraving. Due to the adoption of the laser engraving method of the plastic component, not only can the display effect of the patterns and characters of the traditional process be realized, but also the defects of the traditional process such as paint dropping, dropping, color fading, non-abrasion resistance, short service life, easiness for storing dirt, environmental pollution and incapability of individualized production can be solved; and moreover, a novel high-efficient and environment-friendly technique for producing any pattern and character with no material consumption can be realized, and a broad individualized exhibition platform can be provided for the individualized times.

Description

technical field [0001] The invention relates to an internal carving method of a product, in particular to an internal carving method of a plastic part which engraves a pattern or a logo in the plastic part. technical background [0002] At present, the patterns appearing on plastic materials such as electrical shells (such as DVD panels), electrical jackets (such as mobile phone protective covers), electrical window panels (such as MP4 window lenses), and electrical buttons (such as telephone buttons, elevator buttons, computer buttons, etc.) are It is realized by printing technology, laser laser and laser marking technology, but these patterns or characters are all on the outer surface of the material. As time goes by and use, these characters or patterns will fall off, fade, wear off and other defects. Some printing materials do not meet the requirements of environmental protection, and will bring harm to the physical and mental health of consumers, and bring great losses ...

AI Technical Summary

Problems solved by technology

Some printing materials do not meet the requirements of environmental protection, and will bring harm to the physical and mental health of consumers, and bring great losses to enterprises and individuals.

[0003] In detail, the pattern or text formed by the printing process is prone to shortcomings such as paint peeling, scratches, fading, non-wear resistance, and short life. The materials used must be environmentally friendly to meet relevant standards, and it is not suitable for personalized production; laser and The pattern or text formed by the laser marking process can realize personalized production, but because the surface or coating of the material is lasered or burned by laser, etc., the material of the outer surface is damaged, and sometimes there is a hand feeling and a depression Parts are prone to dust and dirt, and the coated ones sometimes have shortcomings such as peeling, fading, and non-wearing.

[0004] There are applications of internal engraving technology in the crystal gift industry, but they are all limited to the application of internal engraving in the field of crystal or glass, and have not been applied to large-scale industrial production applications.
