Fiberglass Filter Mesh for Aluminum Casting Filtration
Tired of battling porosity, slag defects, and inconsistent quality in your aluminum castings? The root cause often lies in oxides and non-metallic inclusions carried by the molten metal. SF-Foundry’s High-Silica Fiberglass Filter Mesh for Aluminum Casting Filtration is engineered to be the simplest, most reliable solution. By effectively trapping impurities, it ensures cleaner metal, fewer scrap parts, and higher profitability for your foundry.

The Mesh Filter is a precision-woven, two-dimensional sieve made from ultra-high-purity fiberglass. Designed specifically for the aluminum casting environment (700°C – 850°C), it acts as a physical barrier at critical points in your gating system. It delivers exceptional filtration efficiency without altering your alloy chemistry, making it the ideal choice for gravity, low-pressure, and sand casting of aluminum alloys.
Why Choose SF-Foundry Mesh Filter for Aluminum Filtration?
Our screen filter is designed to solve your core production challenges:
-
Eliminate Defects: Dramatically reduce slag holes, sand inclusions, and porosity caused by oxides and debris.
-
Improve Mechanical Properties: Cleaner metal leads to better tensile strength, elongation, and pressure tightness in final castings.
-
Boost Yield & Profitability: Lower scrap and rework rates directly increase your operational efficiency and bottom line.
-
Ensure Simplicity & Safety: Easy to cut, place, and handle.
Mesh Filter Applications
The mesh filter is proven effective across a wide range of aluminum casting operations:
-
Automotive: Cylinder heads, engine blocks, transmission housings, wheels.
-
Aerospace: Structural components, housings, brackets.
-
General Engineering: Pump and valve bodies, electrical enclosures, heat sinks.
-
Alloys: Excellent for A356, A380, ADC12, and other common foundry alloys.
How It Works: Simple & Effective Integration
-
Select: Choose the optimal mesh size based on your part and alloy.
-
Cut: Easily trim the mesh to fit your sprue, runner, or gate with regular scissors.
-
Place: Position it in the gating system (best practice: at the sprue base or in the runner).
-
Pour: Pour as normal. The filter will work passively to screen inclusions, ensuring only clean metal fills the cavity.
