Explore our elite range of custom metal components fabricated with industry-leading tolerances and verified metallurgical properties.
Bridging traditional casting metallurgy with advanced mechanical engineering to power critical supply chains.
In the global industrial sector, the Polish term "Odlewnictwo" (Foundry/Casting engineering) represents a core pillar of structural manufacturing. From high-integrity valve bodies to intricate aerospace impellers, casting enables the production of complex geometries that would be economically and physically unfeasible to machine from solid billets alone. Today, modern industrial applications demand a seamless integration of investment casting (lost wax casting) and multi-axis CNC finishing.
As heavy industries, automotive sectors, and maritime engineering projects shift toward sustainable and highly efficient designs, the demand for precision alloy castings has scaled exponentially. Global OEMs require partners who not only understand metallurgical science but can also execute post-casting machining with micrometer-level precision.
Rich experience in high-precision investment casting, advanced CNC machining, and complex mechanical assembly.
Established in 2014, Dongguan SX Technology Co., Ltd (Shixin) has spent a decade refining its proprietary casting and machining technologies. Located in Dongguan, China—the global capital of precision hardware supply chains—we have developed a vertically integrated manufacturing ecosystem.
Our core capabilities span across investment casting (predominantly utilizing stainless steel, carbon steel, and specialized superalloys) and precision CNC machining (featuring titanium alloys, copper alloys, aluminum, and cemented carbides). By maintaining both foundry links and advanced CNC machining under one operational umbrella, we eliminate the logistics bottlenecks, communication errors, and quality discrepancies typical of multi-vendor supply chains.
We pride ourselves on offering rapid-response manufacturing. Whether you require a single non-standard titanium screw for mechanical testing or a production run of marine-grade valve bodies, our technical engineering team stands ready to review your CAD files and deliver optimized production solutions.
Our manufacturing facility houses advanced multi-axis CNC machines, turning centers, and comprehensive inspection tools. We adhere to rigorous European and American industrial standards, allowing our products to operate seamlessly in demanding environments such as:
A visual tour of our modern machining floor, foundry facilities, and processing environments.
How we integrate computer-aided simulation, advanced metallurgy, and green-casting practices to meet future demands.
We leverage advanced thermal simulation software to model the pouring and solidification behavior of molten steel and aluminum. This eliminates casting shrinkage, porosity defects, and internal stresses prior to pouring.
Recognized for high strength-to-weight ratios, processing titanium (Ti-6Al-4V) requires rigid setups and optimized chip-breaking tools. Our CNC workshop specializes in non-standard titanium components with zero tool-chatter markings.
Moving forward, we are integrating 3D printed sand molds and wax patterns directly into the investment casting workflow, enabling fast-turnaround prototyping and custom design changes without expensive tool tooling modifications.
Analyzing customer designs for draft angles, parting lines, and shrinkage allowances using high-fidelity modeling systems.
Robotized ceramic shell dipping and environment-controlled drying rooms guarantee consistent mold thickness and reduce shell cracking.
Transitioning to high-efficiency induction furnaces and optimizing heat-treatment cycles to lower the carbon footprint of cast parts.
How Dongguan SX leverages local supply networks to secure reliable delivery to European and North American industrial centers.
China's manufacturing clusters, particularly in Dongguan, present unmatched structural efficiency. We enjoy immediate proximity to raw material producers, secondary finish treatment specialists (electropolishing, hard anodizing, carbonitriding), and specialized logistics nodes. This clustering effect shrinks our production lead times by up to 30% compared to Western foundries.
For regional buyers looking for a localized approach (e.g., in Germany, Poland, or France), this ecosystem guarantees that raw materials are procured rapidly, machined precisely, and quality audited before export.
International trade requires absolute compliance. Dongguan SX Technology ensures all components destined for the European market comply with:
Since 2014, quality has remained the cornerstone of our company's survival and international growth.
We implement comprehensive quality control checks throughout every milestone of production. Our in-house quality inspectors utilize high-accuracy testing equipment, including:
Our relentless focus on maintaining narrow tolerances keeps scrap rates exceptionally low, translating directly to cost savings for our global OEM clients.
Addressing technical and commercial inquiries from procurement managers and design engineers.
