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
Coated sand casting process
Coated sand casting process First, let's take a look at the molding of the core material. Precision molding of modular core in the assembly process. The molding sand tightly surrounds the core, forming a solid outer shell, Every compaction is a deep carving of the strength and accuracy of the sand mold Inject high-temperature metal liquid into the mold cavity, cool and solidify under the action of time, and form castings. Coated sand casting transforms ordinary sand particles into precision castings.
Lost foam casting process for Anode Steel Claw Electrolytic Aluminum Key Conductive Component
This casting is an anode steel claw, a key conductive component in the aluminum electrolysis industry. Today, I’d like to share the lost foam casting box-burying process with everyone.
The effect of negative pressure on lost foam castings
In lost foam casting,the level of negative pressure directly affects casting quality.Improper cintrol of negative pressure can easily lead to defects,such as sand sticking and molten metal back-splash during pouring.I would like to share some thoughts on negative pressure adjustment with fellow foundry professionals.
