Explore our high-performance components manufactured with state-of-the-art lost wax casting and CNC milling/turning processes, adhering strictly to global aerospace, automotive, and marine tolerances.
The modern manufacturing paradigm demands an unprecedented convergence of weight reduction, structural integrity, and cost efficiency. As global industries accelerate toward decarbonization and optimal resource utilization, Precision Cast Components have emerged as the foundational elements of high-stress mechanical engineering. By combining traditional investment casting (lost wax method) with intelligent CNC finishing, companies achieve near-net-shape parts that minimize material waste by up to 70% compared to solid billet machining.
Dongguan SX Technology Co., Ltd. sits at the heart of this industrial transformation. Located in Dongguan, China's premiere high-tech manufacturing hub, Shixin leverages localized supply chain integration and advanced metallurgic engineering to deliver components that meet stringent international regulatory frameworks. Our global presence spans key industrial corridors in North America, Western Europe, and East Asia, supplying sectors that cannot afford a fraction of a millimeter of error.
By executing both casting and CNC secondary machining under one roof, we eliminate intermediate logistical overhead and guarantee absolute traceability of metallurgical composition from ingot to finished piece.
The performance of any precision component is governed by its microscopic grain structure. We select and refine premium alloys to guarantee structural stability under cryogenic and high-temperature operating conditions.

How Dongguan SX Technology bridges the gap between near-net shape creation and tight dimensional tolerances.
Custom tooling molds are developed using CAD files. Wax models are injected to establish precise geometric patterns with controlled shrinkage margins.
Multi-layered ceramic shells are constructed around the wax assembly. The mold is heated to melt out the wax, leaving a high-fidelity internal cavity.
Alloys are melted in induction furnaces, with optical emission spectrometers checking elemental composition before vacuum or gravity pouring.
After shakeout, critical mating features are machined on 3-axis, 4-axis, or 5-axis CNC systems to achieve tolerances of up to ±0.005mm.
Dongguan SX Technology Co.,Ltd (Shixin) has very rich experience in precision casting, CNC machining and assembly. Our products are used in machinery, automobiles, marine, ships, equipment, valves and pumps, electronic appliances, packaging, watches, construction, chemical industry and other industries. The most commonly used materials for investment casting are stainless steel and carbon steel. And the most commonly used materials for CNC machining include titanium alloy, stainless steel, carbon steel, aluminum alloy, copper alloy, cemented carbide, etc. We have advanced manufacturing equipment and technology and are able to respond quickly to your needs.
Our production workspace operates under the highest standards of safety and efficiency, combining automated sand preparation, high-frequency melting induction, precise shell baking, and computerized numerical control. This integrated model is why design engineers and logistics directors globally choose Shixin as their long-term manufacturing supplier.
Our workshop houses multi-axis milling, Swiss-type turning centers, and dedicated metal casting units to ensure continuous operations.
We have professional testing equipment and professional QC personnel, and we adhere to strict tolerances and quality standards for the products we produce. Due to our insistence on strict quality requirements, we have been praised by many customers. Quality is the cornerstone of the manufacturing industry. We firmly believe that only by controlling quality well can we survive, develop, and get better and better. Therefore, we have been working in this industry unremittingly since 2014 and continue to improve the company's team and improve the company's production capacity.
To eliminate porosity, micro-cracks, and dimension creep, Shixin enforces a multi-tier quality assurance protocol. This includes:
Ensuring that our custom metal fabrications transition smoothly into international mechanical assemblies.
Our supply partnerships are founded on regulatory adherence. We comply strictly with ISO 9001:2015 quality systems. For automotive components, we implement core quality tools to meet IATF 16949 guidelines.
Every batch of components is shipped with complete Material Test Reports (MTRs) according to EN 10204 3.1, verifying exact chemical compositions and physical mechanical values.
Our native English-speaking engineering sales team offers Design for Manufacturing (DFM) support, suggesting modifications to gating systems, drafting angles, and radius fillets to reduce cost.
We ensure that all post-treatments (including anodizing, passivation, electroplating, and chemical cleaning) conform to EU RoHS and REACH mandates.
From high-altitude aerospace assemblies to submerged marine hardware, our components are tested in the world's most unforgiving environments.
In marine engineering, saltwater represents a constant threat. Components like High-Quality Stainless Steel Castings for Marine Engineering require Austenitic 316 or Duplex stainless steels. The high molybdenum content in Duplex 2205 restricts chloride-induced stress corrosion cracking, ensuring longevity in seawater pump impellers, propellers, and dock structural brackets.
Modern auto parts demand minimal rotating mass. Our Custom aluminum auto parts CNC machining services deliver lightweight, highly complex manifolds, gearbox brackets, and control arms that lower fuel emissions while supporting high mechanical fatigue limits.
Valve components must handle extreme internal pressures without leakage. Using lost wax investment casting, we manufacture Custom Stainless Steel Casting Valve Components with smooth inner fluid passageways. This reduces turbulent fluid friction and cavity erosion, and post-machining guarantees a bubble-tight seal at critical seats.
For performance applications such as cycling, we design and produce High-Quality CNC Turning Titanium Alloy Screws for Mountain Bike Modification. The Titanium Ti-6Al-4V alloy provides extreme tensile strengths of over 900 MPa while cutting structural fastener weight by 45% compared to steel.
The casting and machining industries are entering a new digital era. Dongguan SX Technology is actively investing in smart manufacturing initiatives to optimize productivity. Our multi-year technology integration plan includes:
Using advanced solidification modeling software, our engineering team runs computational flow simulations of molten alloy before pouring. This allows us to foresee areas vulnerable to shrinkage voids or gas entrapment. By optimizing gate locations and risers digitally, we guarantee 100% density in complex geometries, eliminating structural failures in the field.
