Fiberglass Filter Mesh for High-Temperature Iron Casting
In iron foundries, every pour is a race against time and impurities. Slag, sand, and refractory inclusions can instantly compromise a casting, leading to expensive scrap, rework, and customer dissatisfaction. SF-Foundry’s IronFlow High-Silica Fiberglass Filter Mesh is engineered to be your reliable first line of defense. It provides a simple, cost-effective barrier to trap non-metallic inclusions, ensuring cleaner iron enters the mold cavity, reducing defects, and boosting your overall yield.

The IronFlow Mesh Filter is a premium, woven filtration fabric made from specially formulated high-silica and amorphous fibers. It is designed to withstand the aggressive thermal and chemical environment of molten iron (ductile iron, gray iron, CGI). Acting as a precise two-dimensional sieve within your gating system, it effectively intercepts slag and sand particles without altering the chemistry or microstructure of your iron.
Why Choose SF-Foundry IronFlow Mesh Filter for Your Iron Foundry?
-
Dramatically Reduce Defects: Significantly lowers scrap rates caused by slag holes, sand inclusions, and dross-related defects in final castings.
-
Improve Machinability & Surface Finish: Cleaner iron results in fewer hard spots and inclusions that damage machining tools and impair surface quality.
-
Increase Yield & Profitability: By minimizing pouring-related scrap, you directly improve metal yield and operational efficiency.
-
Simple & Safe Integration: Easy to handle, cut, and install.
Mesh Filter Applications in Iron Foundries
The IronFlow mesh filter is proven across a wide range of iron casting processes and parts:
-
Automotive: Brake discs (rotors), engine blocks, cylinder heads, differential cases.
-
Industrial: Pump and valve bodies, hydraulic components, gearboxes, machine tool bases.
-
Pipe & Fittings: Ductile iron pipe (DIP) fittings.
-
Process Compatibility: Excellent for green sand molding, shell molding, and vertically-parted molding processes.
How It Works In Your Iron Casting Process
-
Select: Choose the mesh size based on your typical slag/sand particle size and required metal flow. 2.0×2.0mm is a common starting point for many gray iron applications.
-
Prepare: Cut the mesh to fit your sprue well, runner bar, or filter cage/core using metal shears. No preheating is required.
-
Place & Secure: Position the filter securely in the gating system. For best practice, place it in a vertical orientation within a properly sized seat or use a dab of refractory paste to hold it in place, ensuring full metal coverage upon pour.
-
Pour with Confidence: Pour as normal. The filter will withstand the thermal shock of the iron stream and begin filtering immediately.
