The pretreatment process of metal corrosion mainly includes: photosensitive etching, screen printing and adhesive sticking. Each process has its own advantages and disadvantages. Plasma etcher manufacturers can choose the corresponding process according to the actual requirements of their products. Let's explain the differences between these three processes in detail:
① Photosensitive etching: as the name implies, photosensitive etching adopts the pre-treatment method of exposure development. The process flow: coating / painting → baking → exposure → development → etching → film stripping → finished product; photosensitive etching process is applicable to high precision requirements, such as stainless steel filter screen etching, screen, lighting, dial etching, double-sided hollowing of hardware and crafts, while traditional screen printing It is difficult to achieve this requirement by brushing and pasting adhesive, and the pre-processing film of photosensitive etching can be designed by itself with low cost and can be reused.
② screen printing: screen printing is widely used in stainless steel decorative boards, elevator boards, advertising signs and signs industries. It is suitable for making a batch of products with a pattern. Process flow: screen printing → air drying / drying → etching → whitening → film removal → plate washing and drying → film coating → finished products. Screen printing etching process is relatively simple, etching pattern is relatively simple, accuracy is not high, and cost is also the lowest;
③ sticking adhesive: widely used in logo advertising industry, the biggest feature of sticking adhesive is that it is convenient to color (spray paint) in the later stage, and the adhesive pattern can be output by itself in the computer; process flow: sticking adhesive → etching → cleaning → drying → spray painting and coloring → high temperature baking → tearing off adhesive → finished product.
