Dongguan SX Technology Co.,Ltd is a globally recognized manufacturing partner with deep-rooted experience in precision investment casting, advanced CNC machining, and comprehensive mechanical assemblies. We serve as a key manufacturing hub for enterprises operating in critical high-reliability sectors including automotive, aerospace, marine engineering, flow control (pumps and valves), medical devices, industrial automation, and consumer electronics.
Our competitive edge lies in our dual-capability: we integrate the metallurgical complexity of investment casting (lost wax process) with sub-micron accurate post-machining under one unified quality management protocol. This seamless transition from raw cast shapes to finalized, ultra-precise parts reduces logistics overhead, guarantees physical and dimensional traceability, and guarantees consistent surface finishes across scale runs.
In modern industrial procurement, relying on low-cost raw materials is no longer sufficient. Supply chain managers are actively seeking Partners who provide high-level engineering intelligence, comprehensive compliance, and robust quality control. The transition toward localized support mixed with a highly optimized Chinese supply chain infrastructure has become a key pattern in the industry.
Dongguan SX Technology Co., Ltd. fills this gap by acting as a direct engineering manufacturer with global communication capabilities. We align our manufacturing operations with international quality management frameworks, allowing engineering leads to purchase components that meet critical tolerances and chemical purity standards directly, without relying on intermediaries.
We work in alignment with ISO 9001 and IATF 16949 methodologies to maintain continuous traceability for our raw materials. From alloy chemistry reports (spectrometer checks) to physical inspections, every step of our process is fully documented.
Our facility processes a broad array of raw materials, ranging from light aluminum alloys and high-purity copper to corrosion-resistant stainless steels (304, 316, duplex) and aerospace-grade titanium alloys.
Our advanced 5-axis CNC machining setup allows us to move from CAD designs to finished metal prototypes quickly. This enables our partners to optimize their design-for-manufacturing (DFM) processes before moving to volume production.
Selecting the ideal combination of material and manufacturing methodology is critical for balancing mechanical properties and production costs. We offer both custom CNC machining and lost wax investment casting to match specific production requirements.

At Dongguan SX Technology, quality control is integrated into every stage of production. Quality is the core foundation of the manufacturing industry; it is the primary factor that drives our business growth and allows us to maintain long-term partnerships. We have continuously refined our internal processes and inspection protocols since our founding in 2014.
Our quality assurance workflow begins with raw material verification via spectrometer analysis. During production, we employ in-process inspection protocols, including automated coordinate measuring machine (CMM) routines, optical comparators, air gaging for micro-bores, and thread-depth verifications. Every batch is supplied with material certificates, dimensional layout reports, and surface roughness documentation.
Our workshop houses high-speed CNC milling machines, multi-tasking CNC turning centers, automatic wire EDMs, and lost-wax investment casting equipment. This selection of machinery allows us to handle both prototype development and large-scale manufacturing runs efficiently.
We manufacture lightweight, high-strength structural parts using titanium and 7075-T6 aluminum, helping aerospace and UAV developers meet strict weight reduction and structural integrity requirements.
Using corrosion-resistant materials like 316L stainless steel and bronze, we produce components designed to withstand harsh marine environments and prevent galvanic corrosion.
We manufacture high-precision components for medical and surgical instrumentation, utilizing biocompatible materials like titanium alloys and custom-machined plastics under clean conditions.
