A cap-style fiberglass mesh filter engineered for molten-metal filtration and high-quality aluminum alloy castings. The three-dimensional fiberglass structure traps non-metallic inclusions, slag and oxides while retaining dimensional stability at casting temperatures, producing cleaner metal and fewer defects in downstream machining and finishing.
Key features
- High-temperature resistance: Made from heat-stable glass-fiber materials designed to maintain structure and filtration performance in molten non-ferrous metal environments.
- High filtration efficiency: Dense, three-dimensional mesh captures inclusions and particulates that cause porosity, surface blemishes and mechanical weakness.
- Chemical stability: Inert fiberglass composition prevents reactions with aluminum and other non-ferrous alloys, preserving metallurgical properties.
- Cap-style form factor: Intended for easy integration into gating systems to provide localized filtration at the sprue/gate interface.
Benefits for manufacturers
- Improved casting yield and reduced scrap by preventing contamination-related defects.
- Better surface finish and tighter tolerances, lowering rework and machining time.
- Enhanced component performance and reliability—critical for automotive, aerospace and structural applications.
- Versatile use across non-ferrous foundry operations (aluminum, zinc, magnesium, copper alloys).
Typical applications
- Aluminum alloy casting for automotive engine blocks, cylinder heads, wheels and structural parts
- Aerospace components requiring high cleanliness and consistent metallurgical properties
- Non-ferrous foundries producing castings for industrial and construction markets
- Any casting process where inclusion control and improved metal quality are priorities
Handling and storage recommendations
Store in a dry, clean environment and handle with clean gloves to avoid contamination. Inspect packaging for damage before use; replace if compromised. Install the cap filter according to your gating system design to ensure full engagement with the melt flow and effective filtration.
For foundries seeking a compact, high-performance solution to reduce inclusion-related defects and raise overall casting quality, this fiberglass cap filter offers a thermally robust, chemically inert option optimized for non-ferrous molten-metal filtration.
