1. E-glass fiberglass mesh filter — For molten aluminum filtration.
TYPE: Normal type & smokeless type.
E-glass fiberglass mesh filter for molten aluminum filtration are designed and woven for the diffusion and filtration of molten aluminum. The molten aluminum is very easy to be oxidated when touched with air. With the use of EFG, the pure molten aluminum is more easier to get during primary melting, foundry casting & scrap recycling. The main types can be the one without coating(white color) or with resin coating(yellow or dark brown color) and smokeless carbonized treatment (black color.)
Mesh Size: 0.8×0.8mm, 1.0×1.0mm, 1.2×1.2mm, 1.5×1.5mm, 2.0×2.0mm, 2.5×2.5mm.
|Work Temperature||700-800 (ºC)|
|Softening Temperature||900 (ºC)|
|Lasting Working Time||<20minutes (700-800 ºC)|
|Hole Size||0.8×0.8, 1.0×1.0, 1.2×1.2, 1.5×1.5, 2.0×2.0, 2.5×2.5mm|
— As the first step filtration for primary smelting.
— In gating system application like filtration for sand casting, gravity casting or low pressure die casting etc.
— As the removal plane to help riser easily to be knock off from castings.
2. High silica fiberglass mesh filter — For iron & small scale steel castings filtration.
TYPE: Normal type & smokeless type.
High silica fiberglass mesh filter is weaved by high silica fiberglass yarn and coated with special resin. It can effectively remove slags, refractory particles and non-metallic inclusions from molten metals. Made from specially treated silica yarns, silica mesh filter are capable of withstanding pouring temperatures up to 1620ºC. Silica mesh filters are ideal for in-mold filtration of gray, malleable, white, compacted graphite and ductile cast irons, as well as non-ferrous aluminum and copper-based metal alloys and many types of small scale steel casting filtration. The main types can be the one with resin coating (Dark brown color) & smokeless carbonized treatment (black color). Another application of silica mesh is that can be used for riser knock-off as a riser removal plane.
|Work Temperature||≤1620 (ºC)|
|Softening Temperature||1700 (ºC)|
Lasting Working Time
|<10minutes (1400-1450 ºC)|
|<4minutes (1450-1560 ºC)|
|<15seconds (1560-1620 ºC)|
|Hole Size||1.5×1.5, 2.0×2.0, 2.5×2.5mm|
Cut pieces for in mold filtration like sand casting, gravity casting, etc. Cut pieces for riser sleeves, bottom or across ports in walls.
Cut pieces to provide a weakened plane for riser knock-off. Cup shapes for investment casting filtration.
— Excellent stiffness and toughness, carbon coating is mechanically stronger and with good anti-impact resistance
— Low coast and easy to use.
— Improves fluidity and metal distribution.
— Removes micron sized inclusions and impurities.
— Can be used with existing pattern equipment.
— Eliminates inclusions created by ceramic chips.
— Carbonized silica mesh filter produces minimal odor and smoke while being used,good for operators healthy and castings quality.
High silica mesh cup filter
High silica mesh filter can extract dross, slag, refractory particles, and non-metallic inclusions from molten metals. It is developed as a low cost, high efficiency alternative to cellular ceramic and reticulated ceramic foam filter. Made from specially treated silica yarns, silica mesh filter is capable of withstanding pouring temperatures up to 1620ºC. Silica mesh filters are ideal for in mold filtration of gray, malleable, white, compacted graphite & ductile cast irons, as well as non-ferrous aluminium and copper-based metal alloys and many types of small scale steel casting filtration. The cup style filter is designed specially for investment casting filtration.
