Precision casting to micro, not rust in the heart-304/316 stainless steel

Product Specification

Precision casting to micro, not rust in the heart-304/316 stainless steel precision casting, injecting pure power into high-end manufacturing

 In the pursuit of extreme cleanliness, super corrosion resistance and millimeter precision in modern industry, a seemingly tiny metal part often carries the core mission of the whole system.

Whether it's a medical instrument in a sterile workshop, a key valve body in deep-sea equipment, or a vacuum joint on a semiconductor production line, they all need a material that is tough, reliable and as pure as ever. 

We focus on building 304/316 stainless steel precision castings, combining advanced technology with excellent materials, and providing "one-step molding and lifelong reliability" metal solutions for high-demand industries. 

Why 304/316 stainless steel? 

304 stainless steel: universal austenitic steel with excellent corrosion resistance, formability and weldability, widely used in food, medical care, light industry and other fields; 

316 stainless steel: contains 2-3% molybdenum, which significantly improves the chloride pitting resistance, and is suitable for harsh scenes such as marine environment, chemical equipment and pharmaceuticals. 

Both of them are non-magnetic (solid solution), easy to clean, in line with international standards such as FDA, USP Class VI and RoHS, and are "golden materials" for high-end applications. 

Precision casting is not only "small", but also "accurate" 

We adopt silica sol Investment

Casting technology to realize: 

One-step molding of complex geometry: inner cavity, curved surface and thin wall (the minimum wall thickness can reach 1.5mm) do not need tailor welding; 

Ultra-high dimensional accuracy:

tolerance level reaches CT4–CT6 (ISO 8062), reducing or even eliminating machining; 

Mirror surface quality: Ra ≤ 1.6μm, and some polished parts can reach Ra 0.4μm, which meets the requirements of clean room; 

Metallography is compact and defect-free:

X-ray or penetrant inspection ensures that there are no pores and shrinkage porosity inside, and the mechanical properties are stable. 

Application field, witness high quality 

Medical instruments: surgical forceps, orthopedic implant tool brackets, dental instruments-biocompatible and can be sterilized at high temperature; 

Food and pharmacy: pump shell, three-way valve, reaction kettle accessories-acid and alkali resistant, no precipitation, easy CIP/SIP cleaning; 

Semiconductors and new energy sources: vacuum cavity flanges, cooling joints and battery structural parts-ultra-high cleanliness and low particle shedding; 

Ships and energy: seawater filter shell and instrument connector-salt spray resistance, high pressure resistance and long service life; 

High-end consumer goods: watch cases, audio stands, luxury hardware-outstanding texture, timeless. 

Customer trust comes from details. "The 316 casting used in our aseptic filling equipment has not been replaced for three years, and it was displayed as a' benchmark part' during customer audit!"
