Constructed from high-purity, alkali-free glass fiber mesh and heat-resistant resin, our Carbonized Fiberglass Mesh Filter is a specialized fiberglass mesh filter engineered for high-temperature molten aluminum filtration in aluminum ingot, slab, and alloy casting.
For enhanced performance, our Carbonized Fiberglass Mesh Filter with an edge C002 undergoes a specialized carbonization treatment. This refines its microstructure and chemical properties, resulting in an exceptionally low gas evolution rate and the ability to withstand extreme temperatures of 700–800°C, ensuring reliable performance in harsh foundry environments.
Its cap-shaped design creates a tight seal at pouring gates, effectively blocking oxides and inclusions to achieve an impurity removal rate exceeding 98%, delivering ultra-clean molten aluminum for superior casting quality. The carbonized treatment further enhances its ability to adsorb and intercept even finer impurities, making it ideal for the most demanding aluminum piston mold manufacturing and other high-precision casting applications.
This Carbonized Fiberglass Mesh Filter is fully customizable (with/without tops, various shapes) to meet diverse needs, and its robust construction minimizes defects, reduces downtime, and enhances production efficiency.

1. Highly Carbonized Fiberglass Mesh Filters Cap For Molten Aluminum Filtration (Black Color)
This represents our premium line of high temperature filters, offering unparalleled performance for critical applications.
Our Highly Carbonized Fiberglass Mesh Filter For molten aluminum filtration deliver superior performance:
Ultra-Low Gas Evolution Rate: Through profound carbonization, our casting filters form a stable carbonaceous structure, releasing minimal gas at extreme molten metal temperatures. This significantly eliminates gas inclusion defects (e.g., pinholes, shrinkage porosity), enhancing density, mechanical properties, and overall casting quality for pristine components.
Exceptional High-Temperature Resistance: Engineered to withstand prolonged and instantaneous temperatures of 700-800°C or higher, our fully carbonized fiberglass mesh filter products resist softening and decomposition. This ensures unwavering structural stability and sustained filtration efficacy throughout demanding molten aluminum filtration casting processes.
Optimized Microstructure & Chemical Properties: Deep carbonization refines the filter medium’s pore structure and surface activity, drastically improving its adsorption and interception capabilities for minute oxides and inclusions. This facilitates highly precise molten metal filtration and yields ultra-clean molten aluminum.
Superior Impurity Removal: Leveraging these advanced characteristics, our filters consistently achieve over 98% impurity removal, leading to significantly enhanced casting quality, simplified post-casting processes, and dramatically reduced scrap rates.

1. Can the Carbonized Fiberglass Mesh Filter for molten aluminum filtration be customized?
Absolutely. We offer fully customizable high temperature filters tailored to your exact specifications. Simply provide the mold diameter, height, and technical drawings, and our engineers will design precision fiberglass mesh filters optimized for your molten metal filtration needs. This includes specialized designs like our Fiberglass Cap Filter for specific applications.
2. Precautions during the Installation Process?
Surface Preparation: Thoroughly clean all installation areas (e.g., mold pouring cup) to eliminate oil, debris, or oxides. Contaminants can compromise the seal between the fiberglass mesh filter and mold, allowing unfiltered impurities to bypass high temperature filtration and degrade casting quality. This is particularly crucial for our Fiberglass Cap Filter to ensure a perfect fit.
Precise Alignment: Ensure the fiberglass cap filter’s lower opening seals flush against the pouring cup base, while the cap top connects tightly to the flow-dividing cone. Misalignment or loose fitting risks displacement during molten metal injection, undermining molten aluminum filtration efficiency. Proper alignment is key for any fiberglass mesh filter.
Temperature Control: Maintain optimal molten metal temperature (typically 650–750°C) to prevent filter softening (high heat) or clogging (low heat). Our high temperature filters, including the Fiberglass Cap Filter, are engineered to withstand extreme conditions, but precise temperature management maximizes filtration performance.
3. How long does it take to customize a batch of special-specification fiberglass mesh filter sheets?
Production lead times depend on customization complexity and order volume, typically ranging from 15–20 business days. We’ll provide a tailored timeline after reviewing your technical requirements, ensuring seamless integration with your manufacturing schedule for your custom fiberglass mesh filter or Fiberglass Cap Filter designs.
4. Can the sample production be free of charge?
Yes, sample fees are waived when orders proceed to production. The cost is fully deducted from your first purchase, allowing risk-free evaluation of our high temperature filtration solutions, including our Fiberglass Cap Filter and other fiberglass mesh filter options.
5. What are the differences between the carbonized molten aluminum filter screen and the general molten aluminum filter screen?
Material and Processing Technology The carbonized molten aluminum filter screen uses alkali-free glass fiber as the base material and undergoes a carbonization treatment. This treatment alters the microscopic structure and chemical properties of the filter screen, endowing it with some special properties, making it a distinct type of fiberglass mesh filter. Our standard Fiberglass Cap Filter offers excellent performance, but carbonization adds specific enhancements.
Gas Evolution Rate After the carbonization treatment, the gas evolution rate of the carbonized molten aluminum filter screen is extremely low. This fiberglass mesh filter, with its high temperature filtration capabilities, can reduce defects such as air holes in castings caused by gas generation, making it more suitable for the casting and filtering of aluminum castings with strict quality requirements. This is a key differentiator from a general Fiberglass Cap Filter.
Filtration Effect The carbonized fiberglass filter screen has a stronger ability to adsorb and intercept impurities such as slag inclusions and oxides in the molten aluminum. It can more effectively remove tiny impurities, further improving the quality of the castings. This enhanced filtration goes beyond what a standard fiberglass mesh filter typically provides.
Cost and Price The production process of the carbonized molten aluminum filter screen is more complex, resulting in relatively higher costs compared to a standard Fiberglass Cap Filter.
