Introduce of shell mold casting:

Shell mold casting, also known as the Croning process, is a precision expendable-mold casting process. It uses fine silica sand pre-coated with phenolic thermosetting resin. The resin-coated sand is brought into contact with a preheated metal pattern; the heat cures the resin and forms a thin, rigid sand shell (normally 5–15 mm thick). Two shell halves are stripped, assembled and clamped. Cores can be inserted if needed. The shell assembly is placed in a flask and backed up by steel shot or loose sand for support. Molten metal is poured into the gating system, solidified, then the shell is broken to remove the casting.

Advantage of shell mold casting processing:

Compared with green sand casting, shell molding delivers better surface finish, tighter dimensional tolerance, high repeatability and less machining allowance.

✅ Excellent surface finish, low surface roughness

✅ Good dimensional accuracy and stable tolerance

✅ Less machining stock, lower machining cost

✅ High production efficiency, easy automation

✅ Good collapsibility of shell, less casting cracking

✅ Thin-wall casting capability (≥1.5 mm)

Suitable fittings:

It is widely used for small & medium precision castings in iron, carbon steel, alloy steel, stainless steel, aluminum and brass. Typical parts: valve bodies, gears, bushings, connecting rods, pump housings and automotive components.
