FM-07 Custom Fiberglass Mesh Filter for Metal Casting
As a professional metal filtration products manufacturer, our company is committed to addressing key pain points in the metal casting industry. During the casting process, non-metallic inclusions in the molten metal can seriously affect casting quality, leading to defects such as reduced strength, porosity, and cracks. Our FM-07 series fiberglass mesh filter for casting, the screen filter, is crafted from special high temperature cloth materials such as high-silica glass fiber. It maintains structural stability in extremely high-temperature environments, and its precisely designed mesh structure effectively intercepts inclusions from the molten metal.
Compared to wire mesh filters, our fiberglass filters offer superior molten metal filtration performance and excellent high-temperature resistance. Using our filter products reduces casting defects, improves yield, and creates significant economic benefits for foundries.

Different Filter Types and Functions
We offer a comprehensive range of fiberglass mesh filters for foundries, optimized for various metal casting processes and temperature requirements. Each type undergoes a rigorous quality control process to ensure consistent filtration performance and reliable performance.
FM-07-AL Series (Aluminum Filter)
Designed for 700-800°C aluminum filtration, offers excellent corrosion resistance and filtration efficiency, making it particularly suitable for the production of high-quality aluminum castings such as automotive aluminum wheels and aluminum alloy structural parts. The filtration mesh primarily addresses alumina inclusions and porosity in aluminum melts, effectively improving the surface finish of castings.
FM-07-FE Series (Iron Filter)
Developed specifically for the temperatures of molten iron and copper, it features a reinforced filtration mesh structure, enhanced thermal and chemical stability, and is suitable for the production of gray cast iron, ductile iron, and various copper alloy castings. The high temperature filter effectively removes sand, slag, and non-metallic impurities from molten iron and copper, improving the mechanical properties and workability of cast iron parts.
FM-07-ST Series (Steel Filter)
Specially designed to withstand the high-temperature steel casting environment of 1500-1700°C. Coated with a special high-temperature-resistant material, it offers excellent thermal shock resistance and structural stability, making the mesh filter suitable for the production of various steel castings. It can effectively remove non-metallic inclusions from molten steel, significantly improving the mechanical properties and surface quality of steel castings.

Frequently Asked Questions
What are the advantages of fiber glass filters compared to ceramic filters?
Our fiber glass filters offer greater flexibility than ceramic filters and can be cut to various shapes and sizes.
Can the mesh filter be reusable?
Fiberglass mesh filters for casting are designed for single use. As the molten metal flows through them, the filter captures impurities and may partially carbonize, making them unusable. A new filter should be used for each casting to ensure optimal filtration.
What precautions should be taken when installing the filter?
Ensure that the filter completely covers the runner cross-section and can be cut as necessary. The installation location should take into account the metal flow path. It is generally recommended to install it inside the pouring cup or at the runner entrance.
Can you customize filters for special shapes?
Yes, we offer full customization services and can design filters in any shape to suit your gating system, including round, square, trapezoidal, or even custom shapes. Simply provide detailed dimensional drawings or samples, and we’ll manufacture them.
Is there a problem using the same filter model for different metals?
Different metal melts have different temperature, fluidity, and impurity characteristics. Using a filter designed for a specific metal will achieve the best results. For example, the FM-07-AL series, designed for aluminum, will quickly fail in a molten steel environment. We strongly recommend selecting the appropriate series for the metal type.
