Losier specializes in Stainless Steel Lost Wax Casting, and we are also a manufacturer and supplier of precision castings in aluminum, brass, or bronze. As a manufacturer and factory in China, we leverage our strong technical capabilities, mature process system, and stable quality control to provide high-performance stainless steel investment castings to global customers, helping to improve equipment reliability, extend service life, and reduce maintenance costs, thereby achieving a higher return on investment.
Stainless steel lost wax casting is a high-precision casting technology with a history of over thousands of years, also known as precision casting. This process, through a sequence of "wax pattern → ceramic shell → dewaxing → casting → shell cleaning → finished product," achieves extremely high fidelity and the manufacture of complex shapes, making it particularly suitable for thin-walled structures, runners, curved surfaces, and irregularly shaped structures that are difficult to achieve using traditional machining methods.
Its core advantages include:
High dimensional accuracy (CT5–CT7 grade)
High complexity, capable of one-step molding
Good surface finish, reducing post-processing
High material utilization, saving costs
Suitable for mass production, with strong stability
Applicable to various materials such as stainless steel, carbon steel, alloy steel, aluminum, and copper
Especially when using stainless steel materials such as SS304, SS316, and SS316L, the products exhibit stronger corrosion resistance, high-temperature resistance, and structural strength, and are widely used in the industrial equipment manufacturing field.
