Precision cutting services from Shenzhen Ruiyihang Technology are based on engineering and are made to fit your unique needs. Since 2008, we've been specialising in making Aluminum CNC Machined Parts with specs as small as ±0.02 mm for businesses all over the world. Our direct-to-customer method between engineers and customers cuts down on confusion, speeds up wait times to as little as three days for easy parts, and makes sure that your designs are perfect for production. With more than nine years of experience making things and engineers with an average of fifteen years of experience, we can turn your plans into high-quality parts, from prototypes to full-scale production.

If you work with us, you don't need an agent. Our experienced engineers talk to you directly to look over your plans, make suggestions for changes that make sense, and solve any problems that might come up during production before they start. By working together, we can save time and avoid mistakes that cost a lot of money.
Your projects need time. We send out quotes quickly after the first review, and for common parts, we can make models within 7 days. If you need something quickly, easy parts can be made in just three days.
For each job, there are differences. We do all of our own manufacturing, so there are no off-the-shelf limits. Our methods are very flexible, so they can be changed to fit your needs, whether you need complicated shapes, special surface treatments, or small production runs.

Advanced 3-axis, 4-axis, and 5-axis CNC machine centers help us make sure that every part is accurate and can be made again and again. Our complete process includes the following:
According to ISO 9001 standards, every lot of Aluminum CNC Machined Parts goes through strict checks both when they arrive and while they are being made. Profile displays and coordinate measuring tools help us make sure that your needs are always met.

Problem-Solving Mindset: We're comfortable with difficult geometry. We encourage challenging projects and create unique methods to make your concepts possible.

Q: What is the average aluminium CNC part lead time?
Complexity, quantity, and finishing needs determine standard manufacturing time of 7–15 days. You can finish simple pieces in 3 days.
Q: How much tolerance is possible?
General tolerance is ±0.05 mm, accuracy ±0.02 mm, and essential dimensions ±0.01 mm or per drawing requirements.
Q: Which surface finishes are available?
You can order anodising, hard anodising, sandblasting, polishing, brushing, powder coating, and bespoke finishes. Quality testing and results are provided for all treatments.
Q: Do you accept small batches?
Absolutely. Flexible production from prototypes to mass products is our speciality. We optimise logistics for global small-batch shipments.
Q: What if quality is an issue?
Quality issues reported within a month are addressed immediately. No exceptions—we remanufacture in one week and reimburse shipping.
