Silicon carbide ceramic foam filters of NINGXIN are designed to improve the quality of nodular, grey, and malleable iron castings. They effectively removenon-metallic inclusions including slag and dross from the molten metal stream. Additionally, they aid in reducing turbulence in the gating system. Their outstanding thermal shock resistance and high strength properties were developed for superior performance in extreme iron foundry applications.

· Clean iron castings
· Increased casting yield
· Fewer inclusions
· Real cost savings from significant
   -reduction in scrap caused by:
   -in-house gross slag defects
   -after-machining sub-surface defects
   -final component leakers and blow holes
· Consistent pour times
