Why choose etching process for coffee filters

Coffee filter etching processing is a very unique process, it can be engraved on the coffee filter with a variety of beautiful patterns and text, through the chemical composition of ferric chloride mixed with water to produce a high concentration of acidity, the use of corrosion characteristics of the metal material to etch the metal material so that it produces a beautiful metal material, due to the processing of the use of microporous processing in the way of filtering coffee powder can make the coffee more delicious.

Coffee filter using a combination of processes for processing, in addition to etching out the flat mesh, and then welded or stamped molding process for deep processing of the filter, so as to achieve the desired finished product. Coffee filter why choose the etching process, the main reason is that through the etching process out of the metal coffee filter thickness can be thinner, the surface is smooth and delicate, the overall product edge without burrs, etching coffee filter no mold costs, only relatively low-priced metal film for design, can greatly reduce the high cost of the mold, only in the back end of the part of the customer needs to be shaped in the process of the cost of the mold, and the Coffee filters processed through the etching out of the retention of product characteristics to avoid the burning point produced by laser processing, the product is not deformed.
