Adopting air blowing pre-compacting and multi-contact high-pressure compaction molding technology, the sand mold has high hardness, uniform compactness, high box closing precision, high casting precision and high yield. The average hardness of the sand mold is 90-95. Hydraulic multi-contact compaction, compaction specific pressure zone adjustable, up to 1.5Mpa;

The control system is equipped with an engineer station, an operation master station and a number of side slave stations, each equipped with a man-machine interface, using industrial computer, numerical control, PLC field bus, servo technology, proportional valve, frequency conversion speed regulation, automatic detection, computer monitoring, etc. Science & Technology;

The action of the whole line adopts the principle of combining electrical, hydraulic and pneumatic transmission, and the key components adopt international brand products to ensure the smooth and reliable operation of the production line;

Use the turntable type plate to replace the frame, put two upper and lower type plates on the turntable, replace each type, and create the upper and lower type;

The whole line is automatic and effective, the casting precision is high, and the working environment is clean. It is the current scientific modeling production line. It has been widely used in the mass production of automobile castings and other gray iron, ductile iron, cast steel and other castings.
