Dongguan SX Technology Co.,Ltd has very rich experience in precision casting, CNC machining and assembly. Our products are widely implemented in demanding industries such as machinery, automobiles, marine, ships, equipment, valves and pumps, electronic appliances, packaging, watches, construction, chemical industry and other industries.
The most commonly used materials for investment casting in our workshops are stainless steel and carbon steel. Furthermore, the most commonly used materials for CNC machining include titanium alloy, stainless steel, carbon steel, aluminum alloy, copper alloy, cemented carbide, and other advanced structural alloys. We possess advanced manufacturing equipment and technology, enabling us to respond quickly to your complex manufacturing needs with tight-tolerance execution.
Industrial hubs like Dongguan consolidate primary metal suppliers, secondary finishing processes (e.g., anodizing, passivation, PVD coating), and raw material verification services within a tight geographical radius, streamlining overall production timelines.
Integrating advanced lost wax investment casting with high-precision CNC multi-axis milling under one factory umbrella enables cost-effective raw casting alongside high-tolerance mating surface finishing.
Chinese manufacturers are highly experienced with difficult-to-machine superalloys, medical-grade titanium (Gr5), hardened tool steels, and sintered cemented carbides, applying tailored tooling and machining speeds to maintain component integrity.
By utilizing robotic arm systems to feed raw materials into multi-pallet CNC machines, modern factories run automated shifts. This maintains low costs and ensures high structural repeatability across large batches.
Simulating machining cycles using CAD/CAM digital twin software helps identify tooling collision points and stress deformations before cutting metal. This significantly reduces waste and improves precision.
Global buyers now demand eco-friendly manufacturing practices. Sustainable shops prioritize closed-loop metal scrap recycling, environment-friendly coolant mist systems, and energy-optimized casting furnaces to lower the overall product carbon footprint.
For harsh offshore and marine applications, components must resist corrosion and pitting. We supply cast and post-machined stainless steel impellers, propeller shafts, and structural brackets that withstand continuous saltwater exposure.
Valves and pumps operating in chemical processing and pipeline systems must maintain structural integrity under high pressure. Our precision investment cast valve bodies and CNC machined seats ensure airtight sealing and zero micro-porosity defects.
Modern electronics require light weight, high heat dissipation, and tight tolerances. We manufacture custom aluminum and copper heat sinks, structural internal brackets, and external shield housings with thin walls down to 0.5mm.
Engine mounts, gear elements, suspension arms, and structural housings need to withstand cyclic fatigue. By utilizing carbon steel casting and high-speed CNC milling, we deliver high-tensile parts capable of millions of operating cycles.
The watches and fine instrument markets require exceptional aesthetic finishes alongside dimensional precision. Our multi-axis micro-machining and polishing centers create immaculate components with mirror-finished surfaces.
We have professional testing equipment and professional QC personnel, and we adhere to strict tolerances and quality standards for the products we produce. Due to our insistence on strict quality requirements, we have been praised by many customers.
Quality is the cornerstone of the manufacturing industry. We firmly believe that only by controlling quality well can we survive, develop, and get better and better. 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 protocols include material spectral analysis, dimensional check verification via Coordinate Measuring Machines (CMM), surface roughness analysis, hardness testing, and pressure testing for valve bodies and fluid housings.
We provide full chemical composition breakdown, tensile test data, and traceability from primary mills for all castings and CNC metal stock.
We supply full dimensional layout reports, highlighting GD&T critical tolerances, verifying out-of-roundness, parallelism, and flatness.
We conduct design-for-manufacturability (DFM) reviews to identify tooling draft angles, wall thicknesses, and raw stock optimizations, saving you cost and time.
