Etch resistant layer:
The anti etching layer is about ink or dry film. At present, some businesses have introduced ink jet printing anti etching ink, but whether the precision can meet the product requirements needs to be considered.
There are many printing methods of printing ink, which can be selected according to different products, including the following:
Traditional manual or automatic printing: it can only be printed on one side.
Coater: obvious advantages, fast coating speed, can be coated on one side or on both sides.
At present, there are about several kinds of exposure machines. One is the traditional air-cooled low-power exposure machine. Such exposure machines have poor accuracy and low efficiency, and are only suitable for simple label products.
若要做高精度的产品，建议大功率水冷u型槽模具 井盖钢模具 保定雅思 一次性止血带 保定养老院 保定水处理设备 一次性止血带 式曝光机，或LED平行曝光机。此两款机型各有优缺点，水冷式曝光机功率大，能耗高。而LED曝光机是属冷光源曝光机，能耗低，精度也好，不过就是价格比较高。但这两款机型效率高，光源也稳定，产品良率也高。但具体选用哪个可以根据各自需求进行选择。
To make high-precision products, high-power water-cooled exposure machine or LED parallel exposure machine is recommended. These two models have their own advantages and disadvantages. The water-cooled exposure machine has large power and high energy consumption. The LED exposure machine is a cold light source exposure machine with low energy consumption and good accuracy, but the price is relatively high. But these two models have high efficiency, stable light source and high product yield. But the specific choice can be made according to their needs.
