Honeycomb ceramic straight hole filter is used to improve and enhance the quality of aluminum, copper, ductile iron, grey iron, and tough iron castings. Honeycomb ceramic straight hole filter through in-mold filtration can achieve the following results :
Purification of molten metal;
Remove non-metallic impurities and gases;
Make the metal liquid filling stable and reduce the vortex;
Simplify the gating system and improve the process yield;
Reduce the porosity of castings, optimize and refine the metal structure;
Improve the surface quality and mechanical properties of castings;
Reduce the rejection rate of castings ;
Reduce processing allowance and improve tool life, reduce casting costs.
The honeycomb ceramic straight hole filter produced by our company has high filtration efficiency, good thermal shock resistance and high temperature strength, and can withstand extreme environment in the casting process. The materials of honeycomb ceramic straight hole filter produced by our company mainly include cordierite, mullite, zirconium mullite, zirconium corundum, etc.
