Explore our top-tier manufacturing services engineered to deliver exact geometry, structural integrity, and exceptional mechanical performance.
Established in 2014, Dongguan SX Technology Co.,Ltd has built a formidable reputation as an engineering-driven powerhouse in precision investment casting, multi-axis CNC machining, and comprehensive complex mechanical assembly. Our capabilities cover a deep industrial spectrum, producing key structural, functional, and aesthetic components for industries including machinery, automobiles, marine, ships, electronics, medical instruments, valve systems, and chemical process equipment.
We leverage advanced manufacturing processes to turn complex alloy chemistries into components with tight tolerances. Our primary raw material portfolio for investment casting spans stainless steel (including austenitic, martensitic, and duplex grades) and carbon steel. In high-precision subtractive manufacturing, we machine advanced substrates including titanium alloys, high-temp nickel superalloys, copper and aluminum alloys, and cemented carbides, adapting dynamically to the technical parameters demanded by global engineering offices.
Our facility is equipped with automated investment casting lines, 5-axis vertical machining centers, and CNC turn-mill composite cells designed for rapid prototype turns and scaled batch runs.
Multi-axis high-speed CNC milling and precision lathe turning zones configured for lights-out production.
Controlled environment dewaxing, ceramic shell molding, and induction melting furnaces for alloy consistency.
Single-setup processing of complex rotational parts, reducing fixture errors and improving throughput.
In-house mold design and verification using advanced mold-flow simulation software to eliminate gas porosity.
Electropolishing, anodizing, passivating, and mechanical post-processing for challenging environments.
Strict geometric, chemical, and structural validation checking against GD&T engineering prints.
The global supply chain landscape requires manufacturing partners who offer more than basic machining services. Dongguan's industrial ecosystem is engineered to manage supply chain disruptions, optimize lead times, and deliver cost efficiencies.
1. Industrial Clustering: Located in Dongguan, the manufacturing hub of the Pearl River Delta, our facility sits within a network of raw material mills, custom tool-makers, surface finishing providers, and logistics providers. This proximity minimizes raw material transport times and simplifies lead times.
2. Redundant Material Sourcing: Dongguan SX Technology maintains strong partnerships with certified domestic steel mills and alloy stockists. This raw material security protects our production schedules from global supply disruptions, keeping casting runs and CNC cells operational.
3. Agile Production Scaling: Our mix of automated tooling, multi-spindle mill-turn machines, and manual finishing stations allows us to quickly pivot from short-run prototyping to high-volume production. We optimize tool paths and casting yields to pass direct savings on to our clients.
Quality control is central to our manufacturing operations. Since our establishment in 2014, Dongguan SX Technology has worked to refine its quality systems. We maintain strict geometric tolerances and surface specifications for every run.
Our dedicated quality control department utilizes modern inspection instruments, including Coordinate Measuring Machines (CMM), optical comparators, spectrometers for chemical analysis, ultrasonic testers, and digital roughness testers. From incoming raw material verification (spectrographic testing) through in-process inspection (SPC) to final product validation, our processes are structured to ensure every part matches your technical drawings.
"We believe that systematic quality control is the key to business viability, long-term development, and building customer trust."
Building capabilities for tomorrow's engineering challenges. Our roadmap outlines our plan to incorporate automation and data-driven quality systems into our production operations.
Implementing generative tool-path algorithms to reduce cycle times on complex multi-axis milling, optimizing cutting force distribution and extending tool life for nickel-titanium and cobalt-chrome alloys.
Integrating additive manufacturing (DMLS metal 3D printing) with post-precision subtractive CNC milling. This hybrid approach enables the production of internal cooling channels and complex geometries that are impossible to machine with traditional methods.
Deploying IoT-connected machining centers with real-time vibration and temperature telemetry to enable predictive maintenance and automatic offset compensation for consistent part quality.
Our custom components are engineered to perform in demanding operating environments, from marine applications to subsea extraction and high-frequency communication electronics.
Marine environments subject components to chloride stress cracking and galvanic corrosion. We manufacture casting valve bodies and impellers from 316L, Duplex 2205, and Monel alloys. These components are designed for high corrosion resistance and reliable performance in chemical containment, marine navigation, and offshore energy extraction.
Marine Alloys Duplex Steel CastingOperating at extreme ocean depths requires components that can withstand high hydrostatic pressures. We process Grade 5 Titanium (Ti-6Al-4V) to manufacture deep-sea pressure housings, sensor enclosures, and acoustic transponders. These components offer high strength-to-weight ratios and resist long-term seawater exposure.
Ti-6Al-4V Machining Pressure Shells5G base stations, satellite antennas, and RF enclosures require clean electrical shielding, high thermal dissipation, and precise dimensional control. Our multi-axis CNC machines process non-standard aluminum and brass housings, maintaining tight flatnesses and finishes to prevent signal leakage and electromagnetic interference.

We serve clients across North America, Europe, and Asia. To support these global partnerships, we align our operations with recognized international engineering standards and compliance frameworks.
International Standards: We manufacture and inspect components in accordance with ASME, DIN, ISO, and JIS specifications. This ensures that the parts we deliver can be integrated directly into your existing assemblies.
Regulatory & Environmental Compliance: We provide full traceability for our products, including RoHS and REACH compliance documentation, material mill test certificates (EN 10204 3.1), heat treatment charts, and detailed CMM dimensional inspection reports.
DFM Support: Our bilingual engineering team reviews your CAD files to provide Design for Manufacturability (DFM) feedback. This collaborative review helps optimize casting gates, tooling setups, and machining strategies to reduce costs and lead times.
Answers to common questions regarding our machining tolerances, casting capabilities, material options, and quality control procedures.
A: For high-precision parts machined on our multi-axis setups, we can maintain linear tolerances down to ±0.005mm (0.0002 inches) and geometric roundness or concentricity within 0.002mm, depending on the material, component geometry, and thermal stability requirements.
A: For investment casting (lost-wax process), we primarily work with stainless steel (304, 316, 316L, 17-4 PH, Duplex 2205) and carbon steels. For CNC milling and turning, our material portfolio includes Grade 5 Titanium (Ti-6Al-4V), aerospace-grade aluminum (6061-T6, 7075-T6), copper alloys, brass, and cemented tungsten carbide.
A: We conduct optical emission spectrometry (OES) testing on every melt batch before pouring. This verifies that the alloy components (such as Nickel, Chromium, and Molybdenum ratios) match the chemical and mechanical property standards specified in ASTM, EN, or JIS specifications.
A: Mold and tooling design typically takes 10 to 15 days, depending on part complexity. Once the tool design is approved, prototype casting samples are generally poured, finished, and ready for shipment within 10 to 14 days, accompanied by our initial sample inspection reports.
A: Yes. We support low-volume manufacturing runs, custom prototyping, and initial trial batches. Our manufacturing facilities are configured to scale production smoothly from early-stage design validation to full-scale monthly casting and machining runs.
