How to make etched nameplates?
Etching is a technology that processes metal parts through photochemical reaction and etching. This process makes full use of the advanced computer-aided design technology to make the graphics into film, and then copy the film graphics to the surface of the metal material by photochemical reaction to form a protected metal part pattern on the surface of the metal material, and then by etching Method, the metal parts are produced by eroding the unprotected metal materials.
Compared with the traditional mechanical stamping method, the etching method has the advantages of short production cycle (generally, the product can be manufactured in 3 days), and the size modification is convenient and fast. The mechanical punching method must have high-precision punching equipment and mold processing equipment, and the development cycle takes 2 to 3 months.
Due to the particularity of the etching method, the complexity of the part has nothing to do with the ease of processing. Relatively speaking, the processing of complex parts by mechanical stamping methods often increases the difficulty of manufacturing, and some even cannot be processed. The etching method only needs to design and manufacture film (photosensitive adhesive, etc.), and the new product development cost is low; the metal parts manufactured by the etching method have no burrs, do not change the magnetic properties of the material, and the flatness of the processed product is not changed at all.
Etching method is used for thin metal material processing with large batches, many varieties and large planes, and surface process decoration of metal products (semi-corrosion). It is also suitable for single-piece small batch proofing. It is now used in various integrated circuit lead frames and fluorescent display arrays, screens, precision filters, encoders, microelectrodes, masks, integrated circuit covers, picture tube shadow masks, surface mount, solder paste screens Printing board and other products.
With the improvement of the etching process, the improvement of the design level, the update of the process equipment, the accuracy of the etching products will be higher, and a wider application market will be developed.
There are many types of custom metal nameplates that can be used for different applications: safetying warning, machine instruction, brand logo and more.
Here is a brief introduction of how to make an etched metal nameplates.
1. Tools/Materials preparation:
Aluminum plate, stainless steel plate, titanium plate, copper, etc.
Cutting machine, hair dryer
Etching water
2. Method/Step
2.1 Choose the material
There are many materials like copper plates, stainless steel plates, titanium plates, aluminum plates etc. Each type of metal plate has different characteristics. You can choose the right plate for different styles of signs. Stainless steel has the advantage of corrosion resistance and is a very commonly used plate for making metal signs. Now we choose a thickness of 0.3 mm.
2.2 Tailoring and trimming
According to the designed size, leave a few millimeters of margin on each side of the selected stainless steel plate, mark it and cut it. The cut stainless steel plate often has burrs on the four sides, and it must be filed with a file. After filing, the edge will be smooth.
2.3 Remove oil
After the stainless steel plate is soaked in clean water, put some detergent on the surface, wipe the oil stains on the surface of the stainless steel plate with a clean cloth three to four times, and then rinse with clean water to wash the surface of the stainless steel plate. It will affect the smooth progress of subsequent procedures.
2.4 Blow dry
Use a hair dryer to dry the remaining water droplets on the surface of the cleaned stainless steel plate to avoid leaving water stains.
2.5 etching
The production of stainless steel plate signs is mainly done by etching.
2.6 Surface protection
a, coated with corrosion-resistant photosensitive ink
b, drying
