It can effectively remove slag, refractory particles and non-metallic inclusions from molten metals. 

Made from specially treated silica yarns, the thick type silica mesh filters are capable of withstanding pouring temperature up to 1620℃. 

Silica mesh filter 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. 

Besides the function of molten metal filters, it could be also used for riser knock-off or de-gating knock-off. 

Investment casters have also placed the perform cup shape filters in the wax mold gating systerm to filter metal at pattern entry.

Advantages

1. Low cost and easy to use

2. Improves fluidity and metal distribution

3. Removes micron sized inclusions and impurities

4. Can be used with existing pattern equipment

5. Reduce turbulence

6. Minimize gating system to reduce cost

Key Points of Usage

1. Use area of filter net: F1 = F2 / AxB

● F1: the cross-sectional area of the casting system. 

● F2: the original cross-sectional area of the casting system.

● A: the porosity of the filter screen, generally 50-60%. 

● B: the filtration rate of filter screen, generally 60-80%.

Therefore, the cross-sectional area of the casting system is generally 2-4 times that of the casting system without the casting net.

2. Position of filter screen:

● Place the filter under the sprue cup;

● Placed on the parting surface under the sprue;

● Three different positions on the lap surface of the runner.
