White area process flow of lost foam equipment production line
White area of lost foam casting is used to make white foam models through pre-foaming, ripening, molding, cutting and bonding Raw materials includes EPS, STMMA, EPMMA and other expandable foam materials
Yellow area process flow of lost foam equipment production line
Lost foam casting process of the yellow area is mainly the white mould model clusters coated with special paint, drying in the drying room, the main role of the paint in the Lost foam casting is to isolate the metal liquid and casting, exclude the model of the gasification products, to ensure that the surface quality of the casting.
Black area process flow of lost foam equipment production line
The black area of the lost foam casting process is to replace white foam models with molten iron and form casting,There are three steps:vibration moulding,casting replacement fand sand treatment.
The following elaborates on the advantages of lost foam casting technology from three aspects
casting quality, process design, and production cost
