Electrochemical etching process before processing key: light induction etching, ink printing, sticker labelling, each processing process has its own advantages and disadvantages, etching machine processing manufacturers can be based on the specific provisions of their own goods, the selection of the relative corresponding processing technology. Below we will actually explain the differences between the three processing techniques:
1, light induction etching: frankly speaking, light induction etching is the choice of exposure developer solution before the solution, the production process: sizing / spraying → baking → exposure → developer → etching → decoupage → finished products; light induction etching processing technology applicable to the higher precision provisions, such as: stainless steel plate screen etching sheet, stainless steel screen, lighting, etching of cases, hardware crafts on both sides of the hollowing carving, etc., and the traditional type of Ink printing and sticker labels, it is difficult to do this kind of regulations, and light induction etching before the resolution of screen printing screen film can be their own design programme, low cost, can be reused many times;
2, ink printing: ink printing is commonly used in stainless steel engineering board, lift car panels, advertising and publicity signs in the field of identification, applicable to a pattern design to do a batch of goods, the production process: screen printing ink → drying / drying → etching → whitening → film → wash plate air drying → overlaying the sub-film → finished products; ink printing etching process is relatively simple, etching pattern design is relatively simple, precision is not high, the cost of fees is also less ;
3, sticker labels: commonly used in signage and advertising industry, sticker labels is a larger feature is the convenience of late colouring (spraying), sticker label pattern design can be exported on the computer itself; production process: sticker labels → etching → cleaning → air-drying → spraying colouring → high temperature baking → tear off the sticker labels → finished products.
