Engine
The engine is the core assembly of power equipment. Internal components including pistons, cylinder blocks, crankshafts, intake housings and turbine structures are high-precision load-bearing precision parts. Equipped with 5-axis CNC, metal 3D printing, die casting and vacuum casting technologies, Duomi Precision provides custom prototype manufacturing and small-batch precision machining for full sets of engine components. We reproduce complex oil passages, heat dissipation cavities, special-shaped turbine blades and integrated cylinder head structures with strict control over dimensional tolerance, sealing performance and coaxiality. Our services support R&D testing and exhibition prototype display for fuel vehicles, new energy vehicles, construction machinery and UAV power assemblies.
Product Details
We provide custom prototyping services for engine parts of fuel vehicles, hybrid new energy vehicles, construction machinery, aerial UAVs and generator sets. Machinable structures include cylinder heads, turbine blades, intake manifolds, pistons, crankshafts, heat dissipation cavities and integrated hollow oil passage structures. Main raw materials cover 6061/7075 aluminum alloy, stainless steel, high-temperature resistant alloy and engineering plastics. Complete professional surface treatments are available: hard anodizing, polishing, sandblasting, carburizing and electroplating, delivering excellent high-temperature resistance, corrosion resistance and structural strength. Full-process precision inspection via 2D & 3D coordinate measuring machines ensures reliable sealing, assembly and dynamic balance performance for direct bench testing. Finished engine prototypes and components are widely used for functional verification, bench tests, new product evaluation and physical exhibition display, delivering one-stop custom prototyping solutions for engine R&D projects.
