Continuous heating, until material melts becomes liquid；
S3: stir, when material melts becomes liquid, is stirred for liquid by agitating device, until liquid
Everywhere without obvious difference；
S4: residue is collected, and by filter, for stirring, successful fluent material filters, and residual filter out
Slag carries out centralized collection；
S5: mould prepares, and mold clean is clean, and reinforces the connection of iron core and mould, prevents iron core from the feelings rocked occur
Condition occurs；
S6: waxing prepares, the mould after reinforcing and cleaning and iron core plate wax layer；
S7: injection material, is injected the fluent material after filtration in mould by inlet, and after injection material,
Constantly omnibearing beaing is carried out for mould；
S8: re-inject, during constantly beaing so that liquid is constantly compressed in a mold, at this moment, injects crossing
Mouth injects the fluent material after filtration in mould, so repeatedly, until fluent material occurs without the situation of compression；
S9: foundry goods is molded, and is cooled down for mould by cooling device, until fluent material solidifies completely；
S10: the foundry goods demoulding, carries out demoulding process by stripper apparatus for foundry goods, and carries out for the mould after departing from
Clean；
S11: burr process, carries out removing burr for foundry goods by sanding apparatus or water sand blend pressure sandblasting, and makes
Cast(ing) surface is smooth and free from admixture；
S12: final molding, then detection and further finishing are carried out for foundry goods so that foundry goods complies fully with requirement.
Preferably, the smelting furnace mentioned in described S2 is middle frequency furnace or carbon adding type smelting furnace.

1 part.
S2: material melts, after proportionally weighing various materials, is thrown in smelting furnace, and enters for smelting furnace
Row continuous heating, until material melts becomes liquid, smelting furnace is middle frequency furnace or carbon adding type smelting furnace.
S3: stir, when material melts becomes liquid, is stirred for liquid by agitating device, until
Liquid is everywhere without obvious difference.
S4: residue is collected, and by filter, for stirring, successful fluent material filters, and handle filters out
Residue carry out centralized collection.
S5: mould prepares, and mold clean is clean, and reinforces the connection of iron core and mould, prevents iron core from occurring rocking
Situation occur.
S6: waxing prepares, the mould after reinforcing and cleaning and iron core plate wax layer.
