For modern engineering and procurement leads seeking high performance, reliability, and next-generation lightweight components.
As the lightest structural metal available on Earth, magnesium is 33% lighter than aluminum and 75% lighter than steel. This makes it an ideal candidate for applications requiring high strength-to-weight ratios, electromagnetic interference (EMI) shielding, and exceptional vibration dampening. However, casting and post-machining magnesium alloy presents unique challenges. Molten magnesium has a strong affinity for oxygen, requiring sophisticated protective gas atmospheres (such as SF6/N2 mixtures) during high-pressure die casting (HPDC) to prevent oxidation.
At Xinyunyang, we utilize state-of-the-art cold and hot chamber die-casting machines. By controlling injection speeds within microsecond increments and maintaining optimal mold temperatures via advanced thermal control units, we virtually eliminate internal porosity—a common failure point in low-grade commercial castings.

Combining decades of metallurgy and precision manufacturing experience, we map our process to exceed standard industrial specifications.
We perform exhaustive dynamic computational fluid dynamics (CFD) modeling to map melt-front advancement, heat dissipation, and solidification sequences. This proactively prevents thermal hot spots and gas inclusion before tooling steel is ever cut.
Our casting cells utilize high-vacuum extraction systems to create negative pressure inside the mold cavity. This allows the magnesium melt to fill complex, thin-walled areas (down to 0.8mm) with absolute structural integrity, drastically reducing porosity.
Unlike raw foundries, Xinyunyang excels in high-precision post-cast machining. Drawing on our deep experience in processing hard Kovar alloys, we maintain critical tolerances down to ±0.005mm on crucial interfaces and seal surfaces.
To prevent galvanic corrosion, we offer premium in-house surface treatments including Micro-Arc Oxidation (MAO/PEO), chemical conversion coatings, and electroless nickel plating to survive high-humidity salt-spray environments.
Helping global procurement teams address complex mechanical limitations and sourcing hurdles.
Precision is paramount in optical communication networks and micro-fabrication cleanrooms. Our lightweight magnesium components minimize physical vibrations and offer excellent thermal conductivity, keeping lasers and sensors aligned under variable heat loads.
Every gram eliminated from flight structures directly translates to increased payload and fuel efficiency. We manufacture complex satellite chassis boxes, flight deck components, avionics racks, and internal defense electronics boxes using premium WE43 and AZ91D alloys.
From portable diagnostic screens to advanced surgical robotics, our magnesium casting solutions offer essential weight reduction for handheld mobility while ensuring high impact resistance and shielding against electromagnetic noise.
By leveraging the highly integrated industrial infrastructure of Shenzhen, China, Xinyunyang Precision has implemented a true Factory 4.0 standard. We combine raw casting, multi-axis high-speed CNC machining, and automated coordinate measuring inspection into a single highly responsive workflow.
Our smart digital systems optimize production scheduling, achieving a 15% to 20% improvement in turnaround speeds compared to traditional foundries. This provides global OEMs with a resilient supply chain capable of handling demand spikes and design changes seamlessly.

Answering critical engineering and metallurgical questions to help procurement managers optimize component performance.
With high-vacuum cold-chamber die casting, we routinely achieve wall thicknesses down to 0.8mm to 1.0mm for compact electronic frames and structural brackets. Achieving this requires precise control of high-speed injection and mold temperature profiles to prevent premature freezing of the molten metal.
Because magnesium has a highly negative electrochemical potential, contact with metals like steel or copper can trigger galvanic corrosion in wet environments. We prevent this by utilizing advanced non-conductive surface isolation techniques, such as Micro-Arc Oxidation (MAO), applying high-performance epoxy powder coatings, and utilizing non-conductive washers in assembly joints.
While standard die castings are limited to ±0.1mm, our high-precision post-cast CNC machining regularly holds critical seal surfaces and bearing bores to tolerances as tight as ±0.005mm. This makes our cast parts fully compatible with the demanding assembly requirements of aerospace, semiconductor, and medical equipment.
While pure aluminum has higher bulk thermal conductivity, magnesium alloys (such as AZ91D) offer a crucial weight reduction of approximately 33%. In mobile communication nodes, aerospace avionics, and high-performance automotive housings, this weight reduction frequently offsets the slight difference in raw thermal conductivity, and we optimize heat dissipation via advanced cooling fin geometries.
Yes. All of our material streams, including Kovar (4J29), titanium, and magnesium alloys, are fully compliant with RoHS and REACH regulations. Our dry-machining options and closed-loop scrap recycling systems minimize waste and protect both workers and the environment.
To guarantee void-free internal structures, we perform rigorous non-destructive testing (NDT). This includes high-resolution X-ray flaw detection, ultrasonic scanning, helium leak path detection (especially critical for hermetically sealed semiconductor and aerospace applications), and Coordinate Measuring Machine (CMM) dimensional verification.
