Today, one thousand ex Anping Wire Mesh Products Co., perforated metal mesh is to introduce you to what to buy? First, because the perforated metal mesh is made of different materials plate stamping forming, so the quality and mold plates will affect the quality perforated metal mesh, so the selection of materials in time to pay attention. Second, the process for galvanized perforated metal mesh perforated metal mesh, with the operation of which depends on the skill and good machines, different materials price sheet. Third, the surface of the perforated metal mesh ceiling treatments focused galvanized metal mesh, to choose the surface evenly, good quality paint punching net. Generated when the punching defect correction (1) 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 is corrected. This method is suitable for plastic good material. (2) when punching blanks aliasing. That punch below the metal pushed to four weeks, blank highly reduced diameter increases, the upper end face depression galvanized perforated mesh, lower end projections. Aliasing extent size before punching blank diameter D0, height H0 and pore size d1, etc. related to the more serious D0 / d1 smaller galvanized mesh, then 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.
