Casting Process
Investment casting is also called lost wax casting, including
waxing, grouping, dipping, melting wax, casting molten metal and
post-treatment. Investment casting usually refers to forming a
pattern in a fusible material, and coating a plurality of layers of
refractory material on the surface of the pattern to form a shell,
and then melting the pattern to discharge the shell, thereby
obtaining a mold having no parting surface, and after high
temperature baking A casting scheme that can be filled with sand.
Lost wax casting is a wax mold in which a part is to be cast with
wax, and then the wax mold is coated with mud, which is a mud mold.
After the mud mold is dried, it is baked into a ceramic mold. Once
calcined, the wax mold is completely melted and lost, leaving only
the ceramic mold. In the general clay mold, the pouring port is
left, and the molten metal is poured from the pouring port. After
cooling, the required parts are prepared.
