Explore our key high-precision components manufactured through advanced material processing, rigorous testing, and high-tolerance standards.
In the global manufacturing ecosystem, the term "foundry" has shifted. Once synonymous with high-volume, low-complexity castings, Chinese investment casting foundries have undergone a significant digital transformation. Today, advanced facilities integrate silica sol processing, computerized casting simulation (ProCAST), and robotic wax patterns handling to produce parts with near-net-shape accuracy and exceptional dimensional stability.
This structural change is driven by the demand for tight tolerances and excellent surface finishes in heavy industries. By utilizing the lost-wax casting technique, modern foundries eliminate complex machining stages, reducing tool wear and production waste. This process provides global purchasers with high-precision parts made from challenging alloys like stainless steel, carbon steel, and titanium.
Dongguan SX Technology Co.,Ltd delivers end-to-end manufacturing solutions that bridge the gap between casting design and final assembly.
Utilizing high-grade Silica Sol processes to cast stainless steel, carbon steel, and specialized alloys. We maintain excellent surface integrity (Ra 3.2 or better) and minimal porosity across complex structural features.
Equipped with 5-axis CNC machining centers, we perform secondary operations on titanium alloys, aluminum alloys, stainless steel, and cemented carbides, achieving extremely tight dimensional tolerances.
We provide full mechanical assembly, custom finishing, surface treatments (anodizing, passivating, plating), and drop-shipping for machinery, automotive, medical, and marine industries globally.
Dongguan SX Technology Co.,Ltd has built a reputation for excellence in precision casting, CNC machining, and complex mechanical assembly. Our capabilities serve a wide range of industries, including machinery, automobiles, marine, ships, equipment, valves and pumps, electronic appliances, packaging, watches, construction, and the chemical industry. The most commonly used materials for investment casting are stainless steel and carbon steel, while the materials for CNC machining include titanium alloy, stainless steel, carbon steel, aluminum alloy, copper alloy, and cemented carbide.
Operating since 2014, we have continuously upgraded our facility in Dongguan, China, combining metallurgical expertise with advanced precision machining. This allows us to handle both small batch prototyping and large volume production runs while maintaining high quality standards throughout.
Navigating the complex landscape of casting procurement requires balancing cost, quality compliance, and logistical predictability.
We provide full traceability for our raw materials, including physical chemical testing reports, non-destructive testing (NDT), and certification tracking, ensuring compliance with global regulatory standards.
By keeping tooling development, metal casting, heat treatment, and precision CNC finishing under one roof, we shorten supply chain delays and reduce shipping interfaces.
We safeguard your designs and CAD models. Through secure networks, NDAs, and strict internal access controls, your intellectual property remains protected at every step of manufacturing.
A tour through the facility highlights our clean casting process, high-performance machinery, and quality testing standards.
We use professional testing equipment and have dedicated QC personnel on staff to ensure our products adhere to strict tolerances and quality standards. Our focus on strict quality control has earned positive feedback from our international client base.
Quality control is fundamental to the manufacturing industry. We believe that maintaining high quality is essential for growth, development, and long-term partnerships. Therefore, we have been working in this industry since 2014, steadily improving our production capabilities and expanding our engineering team.
Our QC laboratory is equipped to perform chemical analysis (OES Spectrometry), dimensional validation (CMM coordinate measurement), mechanical properties testing (tensile strength, hardness testing), and non-destructive testing (PT, UT, X-Ray) to confirm structural integrity before shipment.
How we apply advanced casting techniques to meet the performance and durability requirements of various specialized industries.
Marine environments require high corrosion resistance. We cast duplex stainless steel, super duplex, and titanium components designed for subsea exploration, offshore drilling systems, and marine propulsion.
We manufacture structural brackets, suspension components, and lightweight custom castings using high-tensile carbon steel and aerospace-grade aluminum to help automotive manufacturers reduce weight while maintaining strength.
Using titanium alloys and stainless steel, we manufacture high-precision components for wheelchairs and medical equipment, combining lightweight performance with biocompatibility and long-term durability.
We continuously invest in research and development to align our manufacturing capabilities with modern, digital-first industrial production.
Integrating 3D sand printing and stereolithography (SLA) wax pattern printing to bypass hard tooling phases, reducing validation lead times for prototype castings from weeks to days.
Implementing machine learning-assisted X-ray and automated optical inspection (AOI) to identify and classify internal porosity and surface micro-fissures in real time.
Optimizing shell waste recycling, upgrading to energy-efficient induction furnace power supplies, and targeting a 25% reduction in overall carbon footprint across the casting and machining cycles.
