Aligning manufacturing capacity with modern supply chain requirements
Modern procurement demands resilient, dual-source strategies. We offer agile tooling development, transparent raw material batch tracking, and redundant manufacturing streams to protect production lines from logistics bottlenecks.
We supply products complying with strict international benchmarks, including ASTM, DIN, EN, and JIS standards. Complete material traceability reports (MTRs), chemical analyses, and mechanical properties certificates are provided.
By executing precision lost-wax methods that achieve near-net shape, we substantially minimize raw material waste and subsequent machining time, decreasing final component cost and accelerating time-to-market.
Combining investment casting metallurgy and advanced subtractive machining
Investment casting, or lost wax casting, is the premier process for complex, net-shape parts that require thin walls, tight dimensional tolerances, and high surface finish quality. Our process flows through precise wax pattern injection, ceramic shell building with refractory slurry, wax evacuation, high-temperature shell firing, molten metal pouring under controlled conditions, and post-cast thermal treatments.
By utilizing this methodology, we cast intricate geometries that are difficult or impossible to manufacture with standard sand casting or tooling processes. This results in minimal draft angles, excellent detail replication, and typical surface roughness levels of Ra 3.2 to 6.3 μm before secondary processing.
Selecting the correct alloy is fundamental to resisting corrosion, handling stress loads, and sustaining long operational lifespans. We process a wide range of materials:
While casting provides near-net shapes, high-tolerance sealing surfaces, mating threads, and critical bores require precision subtractive machining. Dongguan SX Technology integrates cast components directly with CNC machining operations, minimizing setup errors. Our CNC milling, lathe turning, and multi-axis machining centers allow us to hit dimensional tolerances as tight as ±0.005mm.
Tailored component design and metallurgy across diverse sectors
