Precision casting of food machinery usually adopts stainless steel material, which requires high surface finish. The stainless steel model is mostly used in 316L and 304 steel, capable of handling complex shapes. The production is mainly completed by the silica sol process.
Our expertise covers a wide range of materials including carbon steel, low carbon steel, medium carbon steel castings, high carbon steel, alloy steel precision casting, high manganese steel, high chromium steel, and high nickel steel. These components serve critical roles in auto parts, forklift parts, ship components, train parts, mechanical engineering, petroleum machinery, and mining machinery. Our products are trusted in more than 20 countries and regions worldwide.
The facility covers an area of 30,000 square meters, supported by more than 200 employees, including 10 R&D personnel and 12 quality control specialists. We operate three production lines: two for composite processes (silica sol + water glass) and one dedicated silica sol process. With an annual output of 8,000 tons, our enterprise is ISO9001:2005 certified and fully approved by environmental protection departments as a green casting enterprise.
Our unique composite process (silica sol + water glass) utilizes low-temperature wax. By using silica sol for the outer four shell layers and water glass for the inner three layers, we produce items with surface finishes and internal quality nearly identical to pure silica sol processes but at a significantly more competitive price. This makes it ideal for large-batch production where quality and cost-efficiency are paramount.
Equipped with a dedicated physical and chemical laboratory, we utilize advanced inspection tools including:
Our machining capabilities include two horizontal machining centers, CNC machining centers, bench drills, vertical and rocker arm drilling machines, milling machines, grinders, planers, and CNC lathes, providing an all-round solution for finished components.
