蝕刻機腐蝕前處理工藝詳解A detailed explanation of the pretreatment process of etching machine

      金屬腐蝕前處理工藝主要有:感光蝕刻、絲網印刷、貼不幹膠,每種工藝都有自己的優點和缺點,等離子刻蝕機廠家可根據自己產品的實際要求,選擇相對應的工藝。下麵91xjcc下载官网就來具體講解這三種工藝的區別:

    ①感光蝕刻:顧名思義,感光蝕刻采用的就是曝光顯影的前處理方法,工藝流程:塗布/噴漆→烘烤→曝光→顯影→蝕刻→退膜→成品;感光蝕刻工藝適用於精度要求較高,如:不鏽鋼過濾網蝕刻片、篩網、燈飾、表盤蝕刻、五金工藝品雙麵鏤空等,而傳統的絲網印刷和貼不幹膠,是很難達到這種要求的,且感光蝕刻前處理菲林膠片可以自己設計,成本低,可重複使用;

   

等離子刻蝕機


   ②絲網印刷:絲網印刷廣泛用於不鏽鋼裝飾板、電梯板,廣告標識標牌行業,適用於一種圖案做一批產品,工藝流程:絲印→晾幹/烤幹→蝕刻→白化→退膜→洗板烘幹→覆膜→成品;絲網印刷蝕刻工藝較為簡單,蝕刻圖案較為簡單,精度不高,成本也是Z低的;

 

   ③貼不幹膠:廣泛用於標識標牌廣告行業,貼不幹膠Z大的特點就是方便後期上色(噴漆),不幹膠圖案可自己在電腦輸出;工藝流程:貼不幹膠→蝕刻→清洗→烘幹→噴漆上色→高溫烘烤→撕掉不幹膠→成品

  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.
