Explore our foundational range of precision cast and non-standard custom machined components, optimized for rapid prototyping and rigorous high-end functional engineering.
Dongguan SX Technology Co.,Ltd holds extensive, verified industry expertise in precision investment casting, secondary CNC machining, and electro-mechanical assembly services. We partner globally with developers and engineers in machinery, automotive, aerospace, marine, pump/valve systems, smart home hardware, medical tools, and chemical processing technologies.
By using premium silica sol and advanced water glass casting processes, we specialize in casting and post-processing metals like stainless steel, carbon steel, titanium alloys, aluminum alloys, copper-based alloys, and cemented carbides. Our integrated facility links quick-turn rapid prototyping workflows with high-efficiency mass production lines to significantly compress your product development lifecycle.
From CAD design optimization (DFM) through wax tooling to finished 5-axis CNC machining, we offer a single point of accountability that ensures component accuracy, material performance, and structural integrity.
Maximize your development efficiency by leverage of Southern China's mature advanced industrial ecosystem.
China's supply chains excel at hybrid prototyping workflows. By utilizing 3D-printed SLA wax patterns or high-speed CNC-machined PMMA molds, we bypass expensive hard steel tooling phases. This drops lead times for complex components from weeks to just days.
Access high-grade stainless steels (304, 316L, 17-4 PH), low carbon steels, aircraft-grade titanium, and specialized alloys. Our localized raw material verification protocols ensure compliance with ASTM, DIN, JIS, and BS standards.
Unlike basic foundries, Chinese factories provide comprehensive secondary machining under one roof. We feature multi-axis CNC mills and high-precision lathes that hold tolerances down to ±0.005mm on critical casting faces.
Our commitment to rigorous processing metrics translates to reliable part performance for industrial partners worldwide.
Modern engineering demands lightweight designs, material efficiency, and rapid transition from concept to volume manufacturing.
Traditional tooling can take weeks and represent significant capital risk. Our adoption of additive manufacturing patterns (SLA/SLS) allows us to build prototype molds directly from 3D CAD data, facilitating rapid structural and flow testing before committing to production tooling.
Before pouring molten metal, our engineers run predictive simulation software. This models fluid dynamics, cooling rates, and thermal shrinkage, preventing defects like porosity, cold shuts, or internal stresses during initial runs.
Investment casting allows engineers to merge multi-part welded assemblies into single, optimized cast components. This lowers weight, removes joint failure points, and cuts down on expensive machining assembly times.

At Dongguan SX Technology, quality is the cornerstone of our operations. We maintain strict control procedures to verify that cast parts comply with chemical compositions and dimension profiles specified by our customers.
Our quality control program uses advanced inspection tooling: Spectrometers for material batch verification, Coordinate Measuring Machines (CMM) for dimensional layouts, and non-destructive testing (NDT) like dye penetrant and ultrasonic inspections to locate potential internal casting defects.
We have operated in the precision metal sector since 2014, consistently upgrading our manufacturing equipment and refining our team's expertise. Our quality culture is driven by a commitment to support our clients' brand reputations in the market.
We engineer custom components to meet the technical standards of diverse international industries.
For marine projects, we cast high-grade stainless steels (CF8M, CF3M) resistant to chloride pitting. Common applications include impeller systems, structural brackets, valves, and non-standard deck hardware designed to endure marine conditions.
We work with titanium alloy (Ti-6Al-4V) components using vacuum-assist casting and CNC finishing. Typical parts include medical orthopedics, surgical tools, and lightweight structural components for aerospace assemblies.
From prototype engine mounts to exhaust manifolds and flow control valve housings, we support automotive development cycles through fast prototype iterations and high-volume manufacturing lines.
