Explore our premium grade custom-manufactured metal parts, delivering outstanding surface finish and dimensional stability.
Established in 2014, Dongguan SX Technology Co.,Ltd has developed rich industrial experience in precision investment casting, advanced CNC machining, and comprehensive mechanical assemblies. We provide robust engineering solutions across diverse verticals including industrial machinery, automotive systems, marine and shipbuilding engineering, complex valves & pump systems, high-precision electronic appliances, packaging equipment, horology, structural construction, and aggressive chemical processing plants.
Our casting processes specialize in Stainless Steel (SS) and carbon steel castings using high-grade silica sol technique to secure exquisite surface roughness (Ra 3.2-6.3) and strict dimensional tolerance (ISO 8062 CT4-CT6). In parallel, our CNC machining capabilities handle high-complexity geometries in Titanium alloy, Stainless Steel, Carbon Steel, Aluminum alloy, Copper alloys, and Cemented carbide.
Bridging the gap between design theory and real-world industrial durability. We develop tailored metallurgy for harsh service environments.
Utilizing high-grade austenitic stainless steels (316L, 2205 Duplex) to resist pitting and crevice corrosion in seawater. Ideal for impellers, propeller hubs, marine brackets, and stern gear components.
Producing precision-cast valve bodies, disc gates, and pump housings that sustain high temperatures and severe flow shear. Full conformance to ASME B16.34 standards for pressure-containing structures.
Engineered to handle persistent thermal cycling and mechanical fatigue. We supply heat-resistant stainless steel manifolds, sensor bosses, turbo housings, and brackets to tier-1 automotive suppliers.
Unlike standard water-glass casting factories that compromise on internal surface roughness, Dongguan SX Technology employs a multi-layered silica sol slurry drying process. This delivers a highly refractory shell mold, ensuring zero sand inclusions and preventing micro-cracking in complex thin-walled stainless steel components.
Tour our state-of-the-art facility featuring mechanized pouring stations, robotic shell-building lines, and high-precision CNC machining divisions.
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 improve the company's production capacity.
Our dedicated Quality Control (QC) department maintains close control over raw materials and finished parts. By checking tolerances using Coordinate Measuring Machines (CMM) and verifying the material's composition using Optical Emission Spectrometers, we prevent structural anomalies and sub-standard parts from passing to shipping stages.
We streamline cross-border supply chains. Every batch conforms to localized compliance standards and technical parameters.
Producing casts conforming strictly to global systems: ASTM (A351 CF8, CF8M, CF3, CF3M), DIN 17445 (1.4408, 1.4308), JIS G5121 (SCS13, SCS14A), and EN specifications.
Each shipment is delivered with EN 10204 3.1 Material Certifications, heat treatment diagrams, hardness test sheets, and structural dimensional verification sheets.
We manage complex logistics including FOB, CIF, and DDP to door. We take care of import customs processes, clearing paths for regional OEM supply partners.
Continuous evolution of processes to drive down manufacturing costs and improve part performance.
By simulating fluid flow and temperature dissipation prior to cutting metal mold toolings, we reduce thermal hotspots, shrink defects, and casting pores, optimizing gate system layouts.
For low-volume customized validation, we utilize SLA 3D printed resin/wax patterns. This eliminates the necessity of tool building for short runs, cutting trial periods from months to a few days.
Transitioning post-processing trimming steps to CNC robotic abrasive belt arms. Additionally, implementing silica shell reclaiming systems to cut environmental footprint and increase raw material efficiency.
