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
