We offer enterprise-level Custom Swiss Machined options at Shenzhen Ruiyihang Technology Co., Ltd. that have been shown to work well in the past. Our engineering team has been specialising in precision parts up to 25 mm in diameter since 2008. They keep tolerances of ±0.01 mm and surface roughness Ra ≤ 0.8 μm. We make high-accuracy stainless steel parts with 100% checking processes using 6 Swiss CNC lathes and engineers with an average of 15+ years of experience. Our ISO 9001-certified center can do both quick prototyping (in as little as three days) and mass production using materials that are FDA-approved.
You should not have to work in a machine. You need a partner in tech.
Our plan is easy to understand. There are no salespeople in between you and the experts. Before we start machining, we look over your plans together, talk about limits, and make design suggestions. It saves time. It stops mistakes that cost a lot of money.
A lot of our clients come to us after having trouble somewhere else. They like how honest we are and how we think about fixing problems. We do more than just follow plans. We make them better.
Swiss-type CNC turning is great for making parts with small diameters and complicated shapes. Our six Swiss lathes are very stable and can work with SS316 stainless steel and other materials. Turning, cutting, drilling, and threading can all be done on the same machine. It cuts down on handling mistakes and makes the dimensions more consistent.
Machine your parts just once. Done right. Do not do any extra tasks unless you need to.

| Inspection | 100% Inspection / Sampling Inspection |
We inspect materials before production starts. Raw material certifications are standard. During machining, operators use calipers, micrometers, and projectors to verify dimensions. Final inspection involves CMM and roughness testers.
You receive parts that match your specifications. No surprises.
If quality issues arise within the same month, we'll remanufacture parts within one week. We cover shipping costs. That's our commitment to you.

Speed: Simple parts ready in 3 days. Standard samples within 7 days. Quick quotes after drawing review.
Flexibility: We're not a mass-production-only shop. Small batches? Complex geometries? Special processes? We handle them all.
Transparency: Want to see your parts being machined? We send photos and videos during production. You'll know exactly what's happening.
Technical depth: Our operators bring 12+ years of hands-on experience. They understand material behavior, tool selection, and process optimization.
Support for startups: New companies especially value our collaborative approach. We provide long-term technical guidance to help you grow.

You stay informed. We stay responsive.
Q: Can you produce Swiss machined parts based on custom designs?
Yes, we manufacture parts from your 2D drawings or 3D CAD files, providing full customization for precision small components.
Q: Do you support prototyping and design iteration?
Yes, we offer rapid prototyping and flexible production to support design changes and development cycles.
Q: Can you combine multiple operations in one setup?
Yes, Swiss machining can integrate turning, milling, drilling, and threading for complex part geometries.
Q: What industries do you serve?
We support medical devices, aerospace, electronics, automotive, and other precision industries requiring tight tolerances and consistent quality.
Q: Do you work with materials beyond stainless steel?
Absolutely. While SS316 is common for Swiss machining, we also process aluminum, brass, titanium, and engineering plastics based on your needs.
