Product Description

Product Parameters

Why the traditional metal wire mesh filters are not good for LPDC castings?

Galvanized steel or iron wire mesh filters are at present commonly used for low pressure castings filtration, especially for aluminum alloy wheels. The wire mesh filters are cost effective, with good strength and flexible on shapes and sizes. Now there is a new and better material to perfectly replace it due to the wire mesh filter has disadvantages.

Using the wire mesh filter, there will be largely Fe element added to the aluminum castings and this will lower the castings mechanical strength, especially for high quality standard, this means critical. For risers containing wire mesh filters after solidification, it can not remelted directly to furnace, even after the treatment. The direct cost is the risers had to be sold as scrap. It's great waste.

Fiberglass fabric mesh filters for aluminum filtration are specially designed and woven for the diffusion and filtration of molten aluminum. High twisted yarns are used to control strand diameters and resist flattening or distortion under pressure from contact with molten metal. The integrity of theweave pattern is maintained by the use of phenolic resin, and by the use of leno or Plain construction in high density. Regular coating and carbonized treatment are both available.

Rigid fibreglass Filters for Low Pressure die Casting aluminium filtration

Aluminum filtration cloth filter

E-glass fiberglass mesh filters 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 and scrap recycling.The main types can be the one without coating(white color) or with resin coating(yellow or dark brown color) and smokeless carbonzied treatment(black color).

SPECIFICATION

FEATURES
Brings down the casting rejection rate due to slag inclusions.
Cheap and cost effective,easy installation.
Do not change molten metal element or contaminate molten aluminum.
Stay away from molten aluminum and easy to handle the aluminum scrap recycling (Fiberglass mesh can float on top of the molten metal when the metal is recycled and can be scooped out), this can greatly reduce cost.
Reduces molten metal turbulence,improves molten metal distribution and flow.
Remove oxides and inclusions to improve castings mechanical properties and surface finish.
Excellent stiffness and toughness,good impact resistance.
Mesh and grid is well organized and highly integrity.

APPLICATION
As the first step filtration for primary smelting
Ingate filtration for sand casting,gravity casting or low pressure die casting
As the removal plane to help riser easily to be knock off from castings

PRODUCT TYPE
Uncoated aluminum filtration mesh with different mesh, in roll, white color
Resin coated aluminum filtration mesh filter: Cut pieces or in roll, Brown color
Carbonized aluminum filtration mesh filter: Cut pieces or in roll, No smoke,lower gas,black color
Sewed fiberglass mesh bag/combo bag, Customs shape as per requested.
