Explore our engineering capabilities through high-precision custom parts, manufactured to strict engineering drawings and micro-tolerances.
Dongguan SX Technology Co.,Ltd stands as an industry-leading manufacturer specializing in precision investment casting, multi-axis CNC machining, and complex component assemblies. Over the past decade, we have established ourselves as a reliable strategic partner for Tier 1 OEMs and global engineering corporations looking for reliable custom machining services.
Our comprehensive production program handles components utilized across critical domains, including marine machinery, high-performance automobiles, deep-sea vessels, heavy industrial equipment, high-pressure valves and pumps, advanced consumer electronics, medical orthotics, packaging machinery, watchmaking, and specialized chemical processing systems.
By using multi-axis CNC mills, Swiss-turn lathes, and advanced metal casting processes, we comfortably navigate complex geometries, challenging structural requirements, and demanding metallic specifications including titanium alloys, high-grade stainless steels, carbon steels, hard tool steels, aluminum alloys, copper-based castings, and tungsten-cemented carbides.
How we mitigate risk, optimize supply chains, and deliver high-yield components to international procurement departments.
We bridge the gap between engineering blueprints and cost-efficiency. Our experienced team performs DFM reviews on all RFQs, identifying design issues to minimize raw material waste, decrease production cycles, and reduce cost per unit.
Global supply chains demand agility. We accommodate custom small-batch prototyping for technical validation, alongside automated production runs. This helps global businesses scale production dynamically.
Every shipment is backed by chemical composition analysis and physical property certificates. We strictly source raw metals from certified suppliers, guaranteeing no structural defects in critical components.
Visualizing our clean, modern manufacturing spaces where high-grade materials are shaped into functional precision components.
Situated in Dongguan, the manufacturing capital of South China, Dongguan SX Technology Co.,Ltd leverages a highly integrated industrial ecosystem. This geographical presence enables cost-effective logistics, immediate access to raw material markets, and direct paths to surface treatment providers (anodizing, electroplating, passivation, powder coating, and heat treatment).
What this means for procurement managers:
In high-precision subtractive manufacturing, quality is a non-negotiable metric. Since 2014, we have invested heavily in our metrology lab and inspector training. We conform to international quality management guidelines to ensure every single workpiece aligns with customer CAD files and design parameters.
Our quality department is equipped with coordinate measuring machines (CMM), optical comparators, digital micrometer sets, thread gauges, roughness meters, and ultrasonic testers. Whether we are producing medical-grade wheelchair components, structural aerospace elements, or complex automotive impellers, we track and report tolerances up to ±0.005mm.
We provide full verification reports, material compliance datasheets, and inspection records to give customers peace of mind prior to dispatch.
Embracing next-generation technologies to increase manufacturing speed, reduce carbon footprints, and achieve design efficiency.
By utilizing machine learning to generate optimal cutting paths, we reduce cycle times, minimize tool wear, and prevent tooling breaks. This directly translates to competitive pricing and faster delivery times for buyers.
Our processes are optimized to minimize energy use, and we recycle 100% of our scrap metal turnings and chips. We also utilize eco-friendly lubricants and cooling fluids to help our clients meet their sustainability goals.
We combine near-net-shape 3D printing and precise casting technologies with secondary CNC machining. This hybrid approach allows us to produce complex geometric internal paths that were once impossible to machine.
From aerospace brackets to customized electronic casings, our manufacturing solutions help engineers around the world convert ideas into real components in as fast as 3 days. Send us your STEP/IGS files and receive an in-depth design feedback review within 24 hours.

Depending on the material, component geometry, and custom requirements, we achieve tolerances down to ±0.005mm (0.0002 inches) for machined dimensions and under Ra 0.4 for surface finishes. Standard machining tolerances are held at ISO 2768-m.
We perform chemical composition verification (using spectrometer analysis) and physical tensile test inspections on incoming material batches. MTRs (Material Test Reports) and RoHS compliance certificates are available for every delivery.
We work with all standard CAD formats, including STEP (.step, .stp), IGES (.iges, .igs), Parasolid (.x_t), and SolidWorks files (.sldprt). We also accept 2D vector PDF drawings with detailed GD&T notations to specify strict tolerance levels.
We do not have a rigid minimum order requirement. We offer rapid prototyping for single components, pilot runs (10-100 units), and continuous production runs of over 10,000 components.
Our options include sandblasting, bead blasting, hard and soft anodizing, chemical passivation, nickel/chrome plating, blackening, brushing, electropolishing, powder coating, and specialized physical vapor deposition (PVD) finishes.
IP security is fundamental to our partnerships. We sign Non-Disclosure Agreements (NDAs) prior to receiving design files. All electronic records, CAD geometries, and toolpaths are stored on secure internal servers and are restricted to authorized manufacturing personnel.
