Common Problem
-
The difference between etching and stamping?
Etching is an extension of the stamping process, etching can solve the precision and half-carving effect that the stamping process cannot achieve! Stamping cost is low, etching in, the cost is relatively higher.
-
What are the materials referred to by metal etching?
The etching we refer to is chemical etching, the general metal can be etched, but different materials of metal need to use the corresponding chemical potion etching, Zhuolida focus on stainless steel, iron, copper, copper alloy and other materials of etching!
-
What is the smallest hole that can be opened by the metal etching process?
The size of the etched hole depends on the thickness of the material, the thinner the material, the smaller the hole, the thicker the material, the larger the hole. The smallest hole that can be etched is 0.1mm, but the material thickness is T=0.03-0.05mm. Generally speaking, the size of the etched hole is 1.2-1.5 times of the material thickness.
-
How thick can the etching process etch steel?
The thinner the material the shorter the etching time, the higher the capacity and high precision. General 0.05-0.3mm thickness is the easiest to etch, thickness below 0.05 is too thin, easy to fold, easy to deform. Thickness greater than 0.5 etching time is long, easy to scrap, low capacity! Zhuolida focus on precision metal etching.
-
There are roll-to-roll etching manufacturers in Shenzhen?
Volume to volume etching to find Zhuolida ah, volume to volume etching in two ways, one is the way of film cutting and then etching, this is generally half etched products, relatively low precision, the other is volume to volume exposure and then etching. Volume to volume etching on the etching process process requirements are high, but can greatly enhance the next process capacity and reduce the cost. Zhuo Li Da is imported roll-to-roll automatic exposure machine, the production of high-precision products!
-
Where can I find a roll-to-roll etching plant?
At the request of the customer, Zhuo Li Da purchased a fully automatic volume to glass exposure machine, volume to volume etching, to meet the customer volume to volume production, greatly improving production efficiency and quality quality, however, this volume to volume production has the requirements of the order quantity, must be in large quantities of products to be on the fully automatic production line! Roll to roll etching factory please find Zhuolida!
-
What is the minimum size of holes that can be etched, and what is the spacing and accuracy of the holes?
The minimum opening is related to the thickness of the material. At present, the minimum hole opening that can be done is 0.1mm, but the thickness of the material must be 0.03-0.05mm. hole spacing to 0.1 thick stainless steel, for example, can be done with a hole spacing of 0.1mm. Depth accuracy of up to + / - 0.0075mm. corresponding: the thicker the material, the hole needs to be correspondingly increased, the hole spacing is also correspondingly widened. The ratio of general open hole to thickness is: ∮=1.5*T.
-
Half etching depth and accuracy of semi-etching products?
The depth of the semi-etched product can be controlled up to 0.05 mm at the shallowest depth until etched through. Depth accuracy tolerances of +/-0.0075 mm can be achieved.
-
Can company logos be etched on steel pipes?
Etching from the perspective of process equipment can be divided into flat etching and three-dimensional etching, the principle of the two etching processes are the same, the equipment is not the same. Plane etching is etched on the plane of the steel sheet similar to A4 paper; three-dimensional etching refers to the etching process on products similar to drums, bowls and iron tubes in three dimensions.
-
Factors affecting etchant properties?
The concentration of etching solution should be determined by test methods according to the principle of metal corrosion and the type of structure of copper foil, it should have a large choice; the temperature has a relatively large impact on the characteristics of etching solution.
-
The etching process will create connection points, is it acceptable to the customer?
Flat etched products will have connection points. Thin material: for 0.1~0.3m thick material, the size of connection point is about 0.5mm, and the connection point of thick material products increases accordingly. The position of the connection point is placed on the parallel straight edge of the product as much as possible. The design of the connection point has two types of projection and notch. Generally, the functional product is designed with concave type, and the appearance product is designed with projection type, and the connection point is removed.
-
Are the walls of the etching process holes vertical? Are there burrs?
The effect of the hole wall processed by the etching process is related to the thickness of the material, the thinner the thickness, the hole wall is vertical, no rolled edges, and no pitting. Miss Kui (yu): 136 2020 3959
