Qingdao HuaxinFoundry Automation ExpertSand Preparation System
Integrated molding line for resin bonded sand castings with flexible production capacity.
Process Flow
First, the pattern is placed in the flask, followed by the addition of resin sand.
These operations allow the resin sand to fully fill the space around the pattern and form the sand mold.
The pattern remains embedded in the sand mold, so pouring cannot begin yet.
After molding is complete, the pattern must be removed.
After pattern removal, the sand mold may undergo flow coating and surface drying to improve casting surface quality.
Finally, the molten metal is transferred and poured into the mold cavity.
The molten metal cools and solidifies in the mold cavity to form the casting.
The automatic no-bake sand molding line mainly comprises the molding, flow coating and surface drying, core setting and box closing, and pouring and cooling process sections. It integrates a no-bake sand mixer, vibrating compaction table, flask turnover and pattern removal machine, flow coating machine, surface drying oven, box closing machine, conveying system, transfer car, electrical control system, and ventilation system, enabling automated operation across sand mold production, box closing, pouring, and cooling.
