Use of advanced molding machine, shoot core machine, shakeout machine, sand machine, sand machine principle

(1) mass production of small and medium sized castings, shall promote the compacted high pressure, static pressure, pressure or gas rushed modelling efficient wet sand molding line, reduce and eliminate shock pressure type modelling; Spreading the resin sand core making, heat, mild cold core box, shell core, etc.), reduce the proportion of oil sands or clay sand core. Promotion of pulverized coal substitute materials used in wet mold casting.

(2), in single piece and small batch production of large castings, continue to promote various types of self-hardening resin sand, furan, Pepset method, alkaline phenolic resin sand, etc.), in the medium and large steel casting production, also can promote the ester hardening water glass sand, glass and elimination of clay sand dry instead.

(3) specific to promote various special casting castings, such as centrifugal cast pipe, light alloy die casting, low pressure casting, silica sol investment casting or silica sol water-glass compound shell making technology, profiles, V method casting, iron mould-tectorial sand, lost foam casting, etc. Should be developed and popularized in addition, it can improve the precision and surface quality of castings series of special coatings and coating technology, such as not placeholder coating, flow coating paint, can control the cooling rate of coating, etc. About fettling, continue to promote a strong cast, shot peening, such as efficient mechanized deoxidization, eliminating water hydraulic deoxidization, deoxidization, reduce manual deoxidization. Of iron castings with shotblast cleaning equipment or cleaning production line, steel or more complex iron big using joint blast cleaning equipment, hydraulic parts and small shell casting parts can use hydraulic or electric electrochemical deoxidization device; Such as online testing organization form production line to consider casting (such as dimensional accuracy, surface hardness, etc.), rough machining benchmark locating surface, antirust processing set casting (dip antirust liquid or primer, etc.). Should also be clear development promotion of manipulator and robot in the shakeout, poured riser cutting, polishing the application of flash burr, improve workers' working conditions.
