It is woven with special high-twist & high-strength alkali-free fiberglass and special post-treatment. The maximum temperature resistance can reach 900 ℃.
Widely used in automobile and motorcycle wheels, cylinder pistons, aluminum rods, aluminum materials, aluminum ingots, aluminum plates and precision casting of all types of aluminum alloy casting.
Parameter
Fiberglass Filter Mesh Sheets are made of high temperature resistant fiber, woven and processed by special technology.
Widely used in automobile and motorcycle wheels, cylinder pistons, aluminum rods, aluminum materials, aluminum ingots, aluminum plates and precision casting of all types of aluminum alloy casting.
High-temperature resistant casting fiberglass fabric filter screen is widely used to filter and purify various metal melts. The following purposes can be achieved through casting fiberglass fabric filter filtration:
1. Effectively remove the harmful impurities such as bubbles, ash oxides and various inclusions in the metal melt, so as to fundamentally eliminate the air holes, slag holes and sand holes of the casting, greatly improve the yield of the casting, and improve the internal quality and appearance quality of the casting.
2. Improve the mechanical properties of castings: fiberglass fabric filters can improve the hardness of castings, uniform surface hardness, and improve the bending strength of castings.
3. Change the graphite shape of the casting, so that the graphite size decreases, the thickness becomes thinner and the shape is slightly bent.
4. Change the machinability of castings and improve the machining efficiency

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.
