Manufacturing Process Flow：

Step	Process	Description & QC
1	Tooling & Wax Injection	Based on 3D drawings, industrial wax is injected into high-precision aluminum molds to replicate exact wax patterns.
2	Tree Assembly	Individual wax patterns are manually welded onto a central gating system to form an efficient "wax tree."
3	Shell Making (Silica Sol)	The wax tree is repeatedly dipped into premium silica sol slurry and coated with refractory sand to build a sturdy ceramic shell.
4	Dewaxing & Roasting	High-pressure steam melts the wax out (lost wax), and the hollow ceramic shell is fired in a high-temperature kiln to gain strength.
5	Melting & Pouring	After strict spectrometer analysis, molten stainless steel (e.g., CF8, CF8M) is precisely poured into the preheated ceramic shell.
6	Knockout & Shot Blasting	After cooling, the shell is broken. Gates and risers are cut off, followed by grinding and shot blasting for a flawless matte finish.
7	Heat Treatment	Solution treatment at 1050°C is performed to eliminate casting internal stress and restore optimal corrosion resistance and mechanical toughness.

From investment castings to fully machined components, we help customers achieve complex geometries, consistent quality, and reliable production of stainless steel parts.
