Valve bodies in pump systems are subjected to high pressures, fluid-induced corrosion, and dimensional stress at sealing interfaces. They must offer structural rigidity, internal flow accuracy, and long-term surface durability. Traditional machining from billets adds cost and limits design freedom. High-pressure die casting using cast-grade aluminum like A413 enables net-shape forming, cost efficiency, and consistent mechanical properties for small to medium-sized valve components.
A413 aluminum alloy is known for its high pressure tightness, excellent fluidity, and superior castability. These properties make it particularly suited for precision valve components requiring complex internal flow paths. Its high silicon content reduces shrinkage defects, while its compatibility with post-machining processes ensures tight sealing surfaces and controlled dimensional fits.
Using aluminum die casting, we produce high-accuracy valve bodies with integrated internal passages, bosses, and connection flanges. Mold design includes venting and thermal channeling to minimize porosity. Wall thickness is controlled to ±0.1 mm, providing consistent casting geometry for downstream processing.
After casting, post machining defines sealing surfaces, mounting holes, and threaded pipe connectors. We maintain flatness within ±0.05 mm on sealing faces and concentricity on cylindrical bores to ensure a leak-free valve assembly. Machining is optimized using custom jigs and multi-axis fixtures for repeatability.
Sand blasting is applied to unify the surface texture (Ra 2.0–3.2 µm) and remove oxides. This improves adhesion for the final coating. The component is then finished with industrial-grade painting to enhance appearance, corrosion resistance, and surface sealing. Paint systems meet fluid equipment standards for chemical resistance and service temperature.
