PASX410 flow divider is made of SUS440 stainless steel

whose shape is hollow ring structure with eight ribs and eight holes in the inner

exhibiting complicated shape.Wax pattern with CO（NH2）2 core shows low production rate and high waste rate.Wax pattern structure was re-designed.Up-part and down-part of the wax pattern were made

respectively

and then they were assembled together.Special designing and manufacturing method was adopted to ensure the location accuracy and interchangeability of up-part and down-part pattern.Through using wax solvent and repairing agent in wax assembling

assembling reliability and precision were ensured.In addition

mold shell baking and pouring process were strictly controlled.Through above measures

investment casting PASX410 flow divider met the designed requirements.
