Flow-Rite® Foundry Filters are available for iron and non-ferrous applications. A large variety of sizes are available.
Benefits of Flow-Rite FC Filters for Foundries
- Cost effective
- Effectively remove non-metallic inclusions in metal castings
- Reduced turbulence in the metal stream decreases oxide formation and mold erosion
- Reduced casting scrap rates and customer returns
- Improved as-cast surface finish
- Improved casting machinability and reduced tool wear
- Highly optimized runner system for improved yield
- Wide range of standard sizes
- Custom sizes and configurations available
DIMENSIONAL AND STRUCTURAL CONSISTENCY
- Unlike some filter types that have a random foam structure, the cellular structure of FlowRite filters is identical from one filter to the next, ensuring a high degree of consistency from pour to pour.
RAPID TOOLING
- CoorsTek facilities are ISO certified and offer numerous capabilities to ensure your metal casting products are made to spec and delivered on time.
- Excellent turn-around
- Compaction tooling tailored to a customer’s specifications
- Multi-axis CNC machinery, heat treating, wire and plunge EDM and other services
USAGE RECOMMENDATIONS
- It is recommended that the runner’s system choke, not the filter, limit the flow rate of the molten metal. The total usable filter area should be larger than the system choke.
- Minimum Recommended Ratios:
- 3 to 1 for gray iron
- 4 to 1 for aluminum and copper based alloys
- 5 to 1 for ductile iron
Note: Flow rates and total flow capacity vary with metallostatic head, metal temperature, metal cleanliness, and metal composition
