Why not use traditional metal wire mesh filters nowadays

Galvanized steel or iron wire mesh filters are used for low pressure castings filtration in the past days, especially for aluminum alloy wheels. The wire mesh filters are cost effective, with good strength and flexible on shapes and sizes.

Metal wire mesh filters aren't obsolete, but their use has declined in many applications due to the development of more advanced, efficient, and cost-effective alternatives. They are still used in specific scenarios where their unique properties are an advantage.

What is the disadvantages of wire mesh filter?

Firstly, Large quantity of Fe element will be added to the aluminum castings, which will casue the castings mechanical strength to be lower. Especially for high quality standard, this means critical.

Secondly, for risers containing wire mesh filters after solidification, it can not remelted directly to furnace, even after the treatment. They can not be recycled to reuse and have to be sold as scrapIt's great waste.

Limitations of Traditional Wire Mesh Filters

Limited Filtration Efficiency: Traditional wire mesh filters are a type of surface filter, meaning they primarily trap particles larger than their uniform pore openings. They aren't very effective at capturing very fine particles or a wide range of particle sizes. This is a significant drawback in industries requiring high-purity filtration.

Vulnerability to Damage: The woven or knitted structure of traditional wire mesh can be fragile. The wires can fray, break, or become distorted due to high pressure, vibration, or abrasive materials. Even small misalignments can compromise the filter's integrity, allowing contaminants to bypass the filter and potentially damage downstream equipment.

Cleaning and Maintenance: While they are reusable, cleaning traditional wire mesh filters can be difficult and time-consuming. Particles can become deeply embedded in the mesh structure, making it hard to restore the filter to its original performance, especially with fine-mesh filters.

Modern Alternatives and Their Advantages

So, more and more foundry factories choose a new and better material to perfectly replace it due to the disadvantages of wire mesh filter. That is Fiberglass mesh filter.

Fiberglass Mesh Filter Significant Feature:

1. It is specially designed and woven for molten aluminum filtration. 

2. High twisted yarns are used to control strand diameters and resist flattening or distortion under pressure from contact with molten metal.

3. The integrity of theweave pattern is maintained by the use of phenolic resin and leno or Plain construction in high density.

4. High temperature carbonized treatment.

5. There is no any metal element mixing during filtration.

6. The liquid after filtration can be recycled again.

7. All shapes can be customized according to clients' requirements.
