Definition: perforated metal mesh is used on different materials marked with holes of different shapes to suit different needs. Material: perforated metal mesh material used most are: stainless steel, carbon steel, galvanized sheet, PVC sheet, cold rolled coil, hot rolled steel, aluminum copper and so on. Category: pattern perforated metal mesh, perforated metal mesh shape, heavy mesh, special thin metal mesh, porous metal mesh, perforated metal mesh wire cutting, laser punching net. Hole punching network specifications main specifications are rectangular hole, square hole, diamond hole, round hole, a long hole, hexagonal hole, cross hole, triangle hole, a long waist hole, plum blossom hole, scale hole, hole pattern, character Network , the word hole, five-pointed star-shaped hole, irregular holes, from the dark hole, Hole, louvers hole and so on. 1. Coil thickness of 0.2mm-1mm, length 20m 2. Aperture 3mm-10mm 3. Zhang thickness 0.2mm-20mm; width * length ≤1.5m * 5m 4. aperture 0.25mm-200mm punching a way, in the same direction continuous blanking: Use a rectangular mold punching network overlap processing methods, can be processed long hole, cutting etc. 2, continuous molding: Forming a large die size than the perforated metal mesh forming methods, such as large-size shutters, roll bars, rolling stairs and other processing methods. 3, nibble: Use small round mold with small step away from the arc continuous punching processing methods. 4, multi-directional continuous blanking: Use small punching mold macroporous mesh processing methods. 5, a single shape: the shape of a shallow mold by drawing molding processing methods. 6, a single punch: the completion of a single punch, including linear distribution, circular distribution, circular distribution, punching holes in the grid. 7, forming the array: the same or different machining workpiece manner pieces in big boards. Rectification of defects (1) generated when punching eccentric correction: Because when punching anvil surface uneven, crooked face punch at both ends and uneven heating billets will produce eccentric aperture. Corrective measures available soaking method: When operating the thin side of the hole wall immersed in water, its temperature decreases, then punch reaming, the wall thickness of the side due to high temperature, plastic and thin, so that the whole wall forgings uniform thickness, eccentricity [1] is corrected. This method is suitable for plastic good material. (2) when punching blanks aliasing. That punch below the metal pushed to four weeks, billet height decreases, the diameter increases, the upper end face of depression, lower end projections. Aliasing extent size before punching blank diameter D0, height H0 and pore size d1 and other relevant, D0 / d1 smaller, the more severe the degree of aliasing. Correction approach is: should control the D0 / d1≥2.5 ~ 3 as well. If you are punching a larger diameter, such as D0 / dl <2.5, the general first punch holes, then reaming, in order to obtain the required aperture. Acoustic highway network can be used for practical purposes punching lots across the city, railway, subway and other transportation facilities in the municipal environmental noise control barriers, building objects, walls, generator room, factory buildings, and other noise sources as the acoustic sound board can be used for building ceiling, wall suction audio network, audio speaker mesh material that can be used for building stairs, balconies, beautifully decorated plate of green tables and chairs can be used for mechanical equipment, protective cover, ornate speaker cover, food, feed, mine with the mill sieve, sieve mine, the word screen, [2] stainless steel kitchen equipment used in fruit basket, food cover, fruit and other kitchen utensils, as well as shopping malls with mesh shelves, decorative exhibition units, grain breathable mesh ventilation use, soccer turf seepage water treatment filter. Punching network is also widely used in the electronics industry, such as dust acoustic enclosures, etc., as shown below: Product Features: Easy to molding · You can paint or polish · Easy to install · · striking appearance of various thicknesses pore size and arrangement of plates · wide selection of good sound-absorbing effect · · light weight · long life · precise size punching network also widely used in chemical machinery, pharmaceutical equipment, food and beverage machinery, cigarette machinery, harvesters, dry cleaning machines, ironing table, silencing equipment, refrigeration equipment (central air) speakers, crafts, paper, hydraulic fittings, filtration equipment and other industries. How to buy because the perforated metal mesh is stamped from sheet made of different materials, so the quality of the die plate punching directly affect the quality of the network, in the choice of the plate and making molds, requires attention. Secondly, the stamping process for punching network, mainly to see the skilled technical staff and operational capabilities and good production machinery between some regular punching network manufacturers are using CNC punching net for production of different thickness plate price range. Finally, the overall surface care, can be divided into dip, spray, zinc, etc., need to pay attention to the uniformity of the surface treatment and coating quality, these are very important.
