1. Technical expertise: The use of photochemical etching technology has changed the traditional way of machining metal parts using cars and punching. The fine processing of various metal, alloy, and stainless steel flat parts ranges from the large-area microporous filter screen used by traditional industry equipment to the small parts that are hard to distinguish by the eyes. According to the picture red, process the flat concave-convex type metal material products, such as: text, numbers and complex drawings and patterns. Manufacture of various precision, free-form through-hole parts. 2. Product features: The product has no burrs, no protrusions, the two sides are the same light and the same; No external impact, no deformation and good flatness in the production process; Short production cycle, fast strain, no mold design and manufacturing; Long life, the entire net is made of a flat plate; 3. Scope of application: Integrated circuit lead frames, fluorescent screen grids, arrays, various spring parts, mobile phone parts, copper or stainless steel printing paste leak plates, metal through-hole mask plates and various metal frames, etc. 4. Technical standards: The finest processing line width: 0.02MM Maximum processing area: 500MMX600MM Material processing thickness: 0.02MM-0.5MM Graphic positioning accuracy: 0.01MM Gloabl Sports Equipments Co.,Ltd , https://www.sandingarchery.com
