Regarding the punched metal plates, the minimum hole Boegger can supply is 0.8 mm. But it can not meet the filtration need, especially the application requiring extremely fine holes. Thus, Boegger adopts another advanced production line - metal etching, which creates chemically micronic flow channels on the surface of metal panel, to enable precision rate ranging from 30 μm to 100 μm absolutely.
This etched plates can be used as fiber filter, textile filter and other filters in food and beverage industrial such as a coffee filter to ensure its mellow smooth taste. The small hole also makes the plate prevent unwanted things out, such as insects, even dust.
