DIMENSIONS
Length(Diameter)*width*height=(35-200)*(35-200)*(11-40)mm
With round,square and rectangle shape.
Tolerance: -1~0mm(size under 100mm) ; -2~0mm(size above 100mm)
Pore size: 10/20/30PPI(Tolerance:± 2PPI)
FLOW CAPACITY
For gray iron: Max. filtration weight.= Filter area(cm) x 4
(For example,50x50x22mm filter,the filtering capacity is 5x5x4=100kg)
For ductile iron: Max. filtration weight.=Filter area(cm) x2
(For example,50x50x22mm filter,the filtering capacity is 5x5x2=50kg)
CHEMICAL COMPOSITION
Al2O3 SIC SiO2
≤35% ≥60% ≤5%
APPEARANCE REQUIREMENTS
*No cracking allowed across the full length of the edge
*Any fine cracks within the filter matrix may not be through-going
*Filters should be free from loose debris
PACKAGE
Carton and pallet.
Established in 2002, Baoding Ningxin was specially dedicated to manufacture molten metal filters.
We offers a complete range of foundry filter products and services. The product ranges from very cost effective fiberglass mesh filter to high filtration efficiency ceramic foam filters. Being the first mass production manufacturer of silica mesh casting filter in China, we have our patented technologies and facilities to supply the state of art mesh filters. In recent years, we also positively develop the ceramic filters based on different material to meet various demand of foundries.
Our foundry filter lines are as follows:
*Aluminum filtration fiberglass mesh, it can be in rolls, pre-cut sheet or special shapes like cap, tubular or funnel etc. With resin coating or degas process.
*High silica fiberglass mesh filters for iron and small scale steel castings, in pre-cut sheet or special cup shapes.
*Ceramic pressed filters for aluminum and iron filtration.
*Alumina ceramic foam filters for foundry or cast house, Max. Size 23"X23"X2".
*SIC ceramic foam filters for iron casting filtration.
*Zirconia ceramic foam filters for steel casting filtration.
We are serving more than 2000 foundries in China and had started overseas marketing since 2010. We are looking for the distributor partners in order to help more foundries worldwide to improve castings quality and reduce cost.
