Swiss Machined Stainless Steel parts work really well when your project needs very accurate measurements and high dependability. We at Shenzhen Ruiyihang Technology Co., Ltd. make high-precision SS316 parts using cutting-edge Swiss-type CNC technology. Our six Swiss CNC lathes can work with pieces up to 25 mm in diameter, with accuracy of ±0.01 mm and surface roughness of Ra ≤ 0.8 μm. We have been in business since 2008 and have over 15 years of engineering experience. We offer fast turnaround times (samples can be ready in as little as 3 days) and 100% custom production that is made just the way you want it.
Swiss machining technology is the most accurate way to make parts with small diameters. In contrast to traditional machining, the Swiss process holds the part close to the cutting tool. This stops vibrations and keeps the piece's shape.
These things happen to you:
When you mix this technology with SS316 stainless steel, you get a material that is known for being very strong, not rusting, and being biocompatible. Because of this, the product parts are great for medical devices, tools used to process food, aerospace uses, and marine settings.

We've bought cutting-edge tools and put together a team of people who have worked together for over 12 years doing precise machining by hand. The building we have here is built to meet your toughest needs:
Production capacity: 6 specialised Swiss CNC lathes that run all the time
Part difficulty ranges from simple pins to complicated parts with many features.
Polishing, deburring, and passivation are all secondary processes that are done in-house.
Assurance of quality: methods that are ISO 9001-certified, with CMM inspections and thorough reports
There are no agents between you and our engineers, so contact is quick. We look over your plans, suggest changes to the design that make it easier to make, and give you useful answers that save you time and money.

Approach based on engineering: You talk to our technology team directly. We look at your needs, tell you what materials and standards will work best, and help you avoid expensive design mistakes before production starts.
Open manufacturing: Do you want to see how your parts are made? You can see pictures and movies of the production process so you know exactly what's going on with your order.
Quick turn-around: Most samples are sent out within 7 days. We can send out simple Swiss Machined Stainless Steel parts in just three days.
Help for businesses that are growing: If your business is brand new, we can't wait to work with you. We offer open ways to communicate, help with technology issues, and support for long-term partnerships.
You can check the quality because all of the raw materials are certified. Checking the arriving materials, taking measurements with callipers and projectors while the work is being done, and finally checking with a CMM are all parts of our review process. Food-contact uses can use methods that are approved by the FDA.

Our fine stainless steel parts are used in many fields, including:
We can make rods, pins, connectors, or complex custom shapes exactly the way you want them whether they are simple or complicated.

Q: Why use stainless steel for Swiss machining?
Precision tiny components in challenging settings benefit from stainless steel's strength, corrosion resistance, and endurance. Chemical resistance and severe temperature performance are very good in SS316.
Q: Is Swiss stainless steel machining difficult?
Swiss machining delivers reliable cutting and great accuracy for tiny items with optimised tools and settings. Over 12 years, our team has developed efficient stainless steel handling processes to maintain tight tolerances.
Q: What types of parts are commonly produced?
Shafts, pins, connections, fittings, and precise medical or industrial parts are typical. Threaded fasteners, bushings, spacers, and sophisticated multi-diameter assemblies are also made.
Every step has strict inspection protocols:
Welcome inspection: Material certification and dimensional verification
Consistent manufacturing measurements with calibrated equipment
Final inspection: 100% critical dimension inspection, complicated geometries CMM reporting, surface roughness verification
Material certs, inspection records, and test data available upon request for complete traceability.
We keep documentation and processes for FDA-compliant and industry-standard applications.
