Precision-machined structural and cosmetic parts manufactured to strict tolerances for global markets.
Dongguan SX Technology Co.,Ltd (internationally recognized as Shixin) has accumulated a wealth of advanced industry experience specializing in precision casting, high-tolerance CNC machining, and mechanical sub-assembly. Established with the core goal of bridging the gap between design innovation and cost-effective manufacturing, Shixin has steadily grown into a reliable global tier-1 contract manufacturing supplier.
Our comprehensive production facility accommodates complex design requests, facilitating rapid prototype generation through to medium-and-high volume run outputs. Our industrial custom products support critical sectors including machinery fabrication, aerospace components, marine equipment, automotive components, chemical processing plants, precision valves and pumps, electronic instruments, and structural packaging assemblies.
We work with an extensive portfolio of structural metals. For investment casting processes, we routinely process high-grade stainless steel variants and carbon steel structures. For high-precision subtractive CNC machining, our material capability spans specialized titanium alloys, high-performance stainless steel, industrial carbon steel, structural aluminum, copper alloys, and high-density cemented carbides.
How optimized Chinese supply chains mitigate global engineering bottlenecks and stabilize production margins.
By localizing foundry capabilities, multi-axis machining facilities, and surface treatment setups in Dongguan (the core of global hardware manufacturing), SX Technology controls structural variables directly at the source. This mitigates inter-facility logistics delays and reduces raw material waste.
Our advanced near-net-shape investment casting processes produce geometries that require minimal finish machining. This enables industrial customers to optimize material utilization rates (often up to 90% yield), particularly in expensive alloys like titanium and stainless steel.
Implementing rapid tooling and custom modular fixtures allows our CNC service lines to generate functional metal prototypes in as little as 3 to 5 business days. This significantly accelerates the engineering validation cycle for global hardware developers.
Developing high-integrity structural components requires a balanced deployment of thermal shaping (casting) and mechanical cutting (machining). At Shixin, we coordinate these workflows to provide optimal mechanical properties at the lowest possible cost.
Investment Casting (Lost-Wax Method): Our foundry produces highly complex components by encasing wax models in refractory ceramic shells. This method is highly effective for complex, curved geometries, undercuts, and internal cooling galleries that are difficult or impossible to machine. We specialize in casting corrosion-resistant stainless steel for marine projects and robust carbon steels for structural machinery applications.
Precision CNC Machining: For components requiring tight dimensional tolerances (down to ±0.005 mm) and high surface finishes, our CNC machining centers utilize state-of-the-art subtractive tools. By deploying 3-axis, 4-axis, and continuous 5-axis machines, we execute non-standard milling, drilling, turning, and thread-cutting on challenging materials, including high-strength titanium alloys and cemented carbides.
Explore our manufacturing setup, where heavy industrial capability meets digital quality verification systems.
Quality is the cornerstone of the manufacturing industry. We firmly believe that only by controlling quality well can we survive, develop, and grow. Therefore, we have been working in this industry unremittingly since 2014 and continue to improve the company's team and production capacity.
Our quality control pipeline relies on both human expertise and advanced metrology hardware to ensure strict compliance with client design blueprints:
Dimensional Verification: Our metrology lab utilizes high-precision Coordinate Measuring Machines (CMM), optical profile projectors, and high-resolution micrometer setups to check linear dimensions, concentricity, parallelism, and flat surfaces.
Material Verification: Direct-reading spectrometers analyze chemical compositions before casting. This ensures that stainless steel grades (e.g., Duplex, 316L, 304) and titanium grades (e.g., Gr. 5 / Ti-6Al-4V) meet chemical standards.
NDT & Surface Quality: Liquid penetrant testing and ultrasonic thickness gauges identify internal shrinkage or surface cracks in structural castings. Surface roughness testers ensure that critical machined seals meet specifications down to Ra 0.4.
Adhering to strict international standards to ensure seamless integration into automotive, aerospace, and medical supply chains.
All raw materials processed at Shixin are supplied with full traceability records, including EN 10204 3.1 Material Certificates. We ensure compliance with RoHS, REACH, and custom conflict-free material sourcing standards for defense and aerospace contracts.
Machined parts are treated with rust preventative oils, wrapped in VCI corrosion inhibitor bags, and shipped in custom-built plywood crates to protect them during transit. We coordinate FOB, CIF, DDP, and DAP logistics through express air cargo or ocean shipping.
Our sales engineers are fluent in technical English and can interpret CAD drawing formats including STEP, IGES, DXF, and DWG. We provide Design for Manufacturability (DFM) reviews to identify potential cost-saving opportunities prior to tooling kick-off.
Our custom-engineered parts operate under high stress, extreme temperatures, and corrosive environments.
Investment-cast duplex and 316L stainless steel structural components are engineered to withstand saltwater corrosion. Applications include marine impellers, subsea valve housings, brackets, and rigging hardware.
From lightweight aluminum suspension mounts to high-strength engine brackets and bus brackets, Shixin components are optimized for fatigue resistance and structural integrity under dynamic load cycles.
High-precision valve bodies, pump housings, and manifold components cast from carbon steel and stainless steel are machined to ensure leak-free operation in high-pressure oil, gas, and chemical systems.
As smart manufacturing evolves, Dongguan SX Technology Co.,Ltd continues to upgrade its production processes. Our growth roadmap focuses on integrating advanced systems to optimize efficiency and component quality:
Predictive Tool Monitoring: By using IoT-enabled vibration and temperature sensors inside our CNC spindles, we monitor tool wear in real-time. This dynamic system prevents micro-fractures in cutting tools, resulting in consistent surface finishes on titanium alloys.
Automated Wax Pattern Assembly: Our casting foundries are adopting robotic arms for assembling wax trees. Automation reduces human handling, which in turn reduces micro-imperfections in investment shells and improves dimensional consistency.
Sustainability Initiatives: We are upgrading our smelting furnaces to high-efficiency induction models to reduce electricity usage. Additionally, recycling and processing metal chips generated from CNC machining helps us build a circular manufacturing loop.
Important information regarding production capacity, material options, tolerances, and ordering procedures.
We achieve standard tolerances of ±0.01 mm for CNC milling and turning. For critical features, we can hold tolerances down to ±0.005 mm depending on the material, geometry, and temperature requirements.
For marine and highly corrosive applications, we recommend investment castings in 316L stainless steel or Duplex stainless steel. These alloys resist chloride stress corrosion cracking and pitting in saltwater environments.
We perform optical emission spectrometry (OES) tests on every melt batch. We supply comprehensive material test reports detailing chemical compositions and mechanical properties (tensile strength, yield strength, elongation) with every shipment.
Casting tooling typically takes 15 to 25 days depending on complexity, with initial sample validation following shortly after. CNC prototype setups can be completed and shipped within 5 to 7 days.
