Due to the chemical way of product molding, there must be the length of time, material thickness problems.Therefore, the etching accuracy of color stainless steel plate will be affected by the following conditions:
1, the precision of stainless steel etching and stainless steel material.
Different materials, in different chemical conditions, the etching effect and speed are different.General stainless steel, copper material USES ferric chloride acid material for etching, and aluminum material is both afraid of acid and afraid of alkali.Under the same conditions of etching, the precision of stainless steel etching will be higher.
2, the precision of stainless steel etching and etching of the chemical solution formula.
The same material, and chemical etching agent formula, such as concentration, temperature, etc., has a direct relationship.
3, the precision of stainless steel etching and the use of equipment.
The quality of equipment, service life, more directly related to the production of the product precision.Accurate equipment, stable system operation, uniform spray system, will have a direct impact on the accuracy of the product.
4, the precision of stainless steel etching and coated by the photosensitive oil.
Good photosensitive ink, the development effect will be better, coating thickness will also have an impact on the accuracy of etching.
5, the precision of stainless steel etching is also affected by the original template.
6. The precision of stainless steel etching is related to whether it is a dust-free cleaning workshop.
All processes are required to prevent dust from falling onto the steel sheet surface of the product.If there is dust attached to the surface, the product will be etched some white spots, corrosion pit phenomenon, such as in the edge of the product will form a hole, seriously affect the shape and precision of the product.
Taking stainless steel as an example, according to the type of product, the precision of high-end precision etching can reach ±0.005mm, and the precision of ordinary etching is generally ±-0.05mm.The etching accuracy is generally directly related to the thickness of the material and is usually proportional to it.For example, the etching accuracy of materials with a thickness of 0.1mm is ±0.01mm, that of materials with a thickness of 0.5mm is ±0.05mm, and that of materials with a thickness of 1mm is ±0.1mm.
