Since 2008, Shenzhen Ruiyihang Technology has been delivering Industrial Aluminum Die Casting precisely made aluminium parts. Our method is based on engineering and blends high-pressure die casting with CNC milling to make complicated parts with accuracy of ±0.02 mm. We offer one-on-one technical help from plan review to delivery, and our engineers have an average of 15+ years of experience. Our integrated manufacturing capability guarantees consistent quality and quick turnaround for uses in robots, electronics, industrial equipment, and cars around the world, whether you need prototypes in three days or large production runs.
You should work with a manufacturer that knows the technology problems you're facing.
We do more than just make parts; we also fix technical problems. Our team looks over your plans with you and makes suggestions for how to choose better materials, build the structure better, and make the manufacturing process more efficient. This joint method cuts down on mistakes and speeds up the project timeline by a lot.
Both speed and accuracy are needed for the product. Under high pressure, we pour liquid aluminium metal into steel moulds, making complex shapes and thin-wall structures all at the same time. Once the casting is done, we use CNC cutting to make sure that all of the important parts are exactly how you want them.
We've been making parts for more than 9 years and have strict quality control at every step of the way.

This is how we turn your idea into finished parts:
Step 1: Design Review & Engineering Support
Before production starts, our experts look over your plans and make suggestions on tolerances, material choices, and surface finishes.
Step 2: High-Pressure Die Casting
Moulds made of precision steel are filled with molten aluminium. Parts harden quickly, but they keep their shape and functional power.
Step 3: Trimming & Secondary Processing
After taking off the gates and flash, we use CNC cutting, drilling, or tapping to make the parts fit together more closely if your plan calls for it.
Step 4: Surface Treatment
You can choose between electroplating, powder finishing, anodising, or shining to get the look and function you want.
Step 5: Quality Inspection
Before being shipped, each batch goes through checks for material approval, measurements, and eye confirmation.

100% Custom Manufacturing
There are no common items here. No matter how many you need—10 or 10,000—every part is made to your exact plans and specs.
Engineering Expertise at Your Service
Talk to skilled experts directly; don't go through middlemen. Get useful tips on how to choose the right materials, make the best use of tolerances, and cut costs.
Integrated Quality Standards
We follow foreign rules, such as FDA rules for materials that come into touch with food. You can get material certificates and salt spray test results by asking for them.
Reliable After-Sales Guarantee
If you report problems with the quality within the same month, we'll have it remade within a week and pay for the shipping.

Several industries use our Industrial Aluminum Die Casting parts:
Power tool housings and coffee machine frames are examples of consumer goods.

Q: What is aluminum die casting used for?
It produces complicated metal parts in large quantities, including housings, enclosures, and structural components.
Q: What are the advantages of aluminum die casting?
High manufacturing efficiency, constant quality, and complicated forms with little machining are its advantages.
Q: Can die casting make precise parts?
CNC mill key sections for tighter tolerances and achieve superior dimensional accuracy.
Q: Which surface finishes are available?
Based on design and application, powder coating, painting, polishing, and anodising are options.
Q: Can you do prototypes and mass production?
Absolutely. We assist prototypes to large-scale manufacturing with the same quality.
Q: How do you guarantee batch quality?
We examine raw castings for flaws, monitor machining measurements during manufacturing, and verify shipment before shipping.
