Product Description
Product Name: Perforated Plates/Perforated Sheets-Oblong Holes
Material: Stainless steel, carbon steel, galvanized steel, aluminum, brass, fiberboard, medium density fiberboard, PVC board and all kinds of synthetic plates.
Holes Pattern: Oblong holes, staggered rows or straight rows
Specification:
Their hole size ranges from 1mm to 100mm, and their plate thickness ranges from 0.1mm to 25mm. Moreover, it is possible for plate thickness to be equal to or greater than hole size, for instance, we can punch 10mm holes in a 12mm thick steel plate. Our factory can design and make a variety of perforated plates or sheets as required.
Uses: Our perforated plates or sheets with oblong holes are mainly used for filtration of solids in oscillation sieves.These uses mainly include screening of coal and mines, sorting and filtration of food and herbal medicines, and purification of chemicals and oil products etc.
chematic Drawings and Technical Parameters: 
Edge:
Standard edge e1 and e2 = 20 to 40 + t1 and f1 and f2 = 20 to 40 + t2 resp. u (average value of different production processes) is determined by the size of plates, width of hole and pitch. Smaller or larger edges e1, e2, f1 and f2 are dependent on the pitch and width of hole.
Please enclose a drawing or sketch with your enquiry or order for special plates or plates with unnormal edges.
