3, quality of precision casting performance.In the service performance of various special operating conditions, such as pressure density and wear resistance, abrasion resistance, heat resistance, low temperature resistance and vibration reduction of vibration absorption and shielding, electromagnetic, ionization), etc;After the sequence processing performance, such as workability, weldability and hardenability, etc.4, precision casting, casting the whole life cycle of the reliability and safety, environmental protection, recycling, remanufacturing, etc.Security, such as the automobile chassis casting castings, pressure container, etc.;Environmental protection, such as some electronic information products castings, strict control the lead, cadmium, mercury, hexavalent chromium serious environmental pollution of heavy metal element content (limit to PPM level);After recycling, the casting scrap, easy regeneration recycling, especially the performance of the recovery of precious metal elements;Remanufacturing, scrap castings by repair (using thermal spraying and surfacing welding, brush plating, electroless plating surface engineering methods such as) after restore its using performance, the ability of performance indicators to meet the new castings.
