Our Casting Process
Prototyping
We use CAD software and CNC machining to create precise prototypes tailored to each client’s casting design.
01
Module Manufacturing
Wax is injected into molds, trimmed, cleaned, and assembled onto gating systems to form wax pattern trees.
02
Shell Making
Pattern trees are repeatedly coated with ceramic slurry and refractory sand, then dried to form a strong shell.
03
Dewaxing
High-pressure steam, hot water, or microwave systems remove wax from the shell, leaving a clean internal cavity.
04
Shell Baking
Shells are fired at 1000–1150°C in kilns to remove residues and strengthen mold structure for casting.
05
Melting and Pouring
Alloys are melted in suitable furnaces and poured into heated shells using ladles, vacuum, or centrifugal systems.
06
Post-Processing
Shells are removed; castings are cut, cleaned, ground, heat treated, chemically treated, and welded if necessary.
07
Inspection and Testing
Dimensional checks, flaw detection, mechanical testing, and composition analysis ensure castings meet required quality standards.
08
