The investment casting is extraordinary, and the corrosion resistance is as good

Product Specification

Precision in Millimeter, Tough in Corrosion ——304/316 Stainless Steel Silica Sol Precision Castings, Defining New Standards for High-end Manufacturing

 In aerospace, medical equipment, food and pharmaceutical, marine engineering and other fields that require almost strict cleanliness, corrosion resistance and dimensional accuracy, a tiny casting often determines the reliability and life of the whole system.

To this end, we build 304/316 stainless steel silica sol precision castings by cutting-edge technology-combining excellent material properties with near-net-shape forming technology to provide "zero compromise" metal solutions for high-demand industries. 

Why choose 304/316 stainless steel+silica sol process?

304 stainless steel-general austenitic stainless steel, with excellent corrosion resistance, formability and weldability; 

316 stainless steel-upgraded version containing molybdenum, with stronger pitting corrosion resistance and chloride resistance, is suitable for harsh environments such as ocean and chemical industry. 

 With Silica Sol lost wax precision casting process, we realize:

 The surface roughness Ra is less than or equal to 1.6 μ m, which is close to the machining level and reduces the cost of subsequent treatment;

The dimensional tolerance reaches CT4-CT6 grade (ISO 8062), and the complex inner cavity and thin-walled structure are formed at one time. 

No sand sticking, no flash, no air hole, compact and uniform casting, stable mechanical properties; 

Environmental protection: the silica sol shell is formaldehyde-free and odor-free, which conforms to RoHS and FDA standards. 

Apply the scene and witness the strength

 Medical instruments: surgical instrument handles, endoscope brackets, dental implant parts-highly clean, non-magnetic and biocompatible;

 Food and beverage equipment: pump valve shell, connector, filling components-acid and alkali resistant, easy to clean, in line with FDA certification;

 Ship and marine engineering: impeller and valve parts of seawater pump-salt spray corrosion resistance, long-term reliability; High-end instruments: sensor housing, flowmeter components-stable size, accurate signal;

 New energy and semiconductor: vacuum cavity connector and cooling system connector-ultra-high cleanliness and low precipitation.

 Our advantage is not limited to "precision" The whole process is controllable: from wax mold pressing, shell baking to solid solution treatment, the whole process of 12 core processes can be traced back;

 Complete material certification: provide EN 10204 3.1 material report, and support the re-inspection of spectral components;

 Flexible customization: support the weight range of 0.1 kg–50 kg, and seamlessly connect single piece proofing to mass production of 10,000 pieces;

 Global delivery: it has been stably supplied to customers in Europe, America, Japan, South Korea and Southeast Asia, and passed the system audit of IATF 16949 and ISO 13485.

 Customer evaluation "316 stainless steel castings are used in our aseptic filling line, and the surface is as smooth as a mirror, without rust for three years, and there are zero defects in customer audit!"
