Investment casting (lost-wax) is ideal for complex geometries, minimizing material waste by pouring molten metal into a custom ceramic mold. CNC machining, on the other hand, is a subtractive process that carves shapes out of solid blocks, offering higher dimensional precision (up to 0.005mm) but yielding higher raw material scrap rates. Combining both methodologies offers optimal pricing and precision.
Every heat of steel or titanium is tested in our quality control lab using an optical emission spectrometer. We verify the chemical distribution (Carbon, Chromium, Nickel, Molybdenum, etc.) to ensure it complies strictly with ASTM, DIN, or JIS standards before any pouring or machining begins. Chemical traceability reports are supplied with all outgoing shipments.
Yes. Our CNC facility operates specialized rigid tooling and cooling systems designed to handle the low thermal conductivity and high work-hardening rate of Titanium (Ti-6Al-4V) and cement carbines. This prevents thermal distortion and delivers high-precision surface integrity for demanding medical, aerospace, and marine components.
Modern digital tracking, English-speaking engineering sales, fast air shipping, and streamlined customs clearance make partnering with Dongguan SX Technology feel like working with a local foundry. We offset geographical distance with faster communication, lower tooling costs, and much shorter production cycles than traditional Western foundries.
