Foundry Impeller Precision Fabrication Lost Wax Investment Casting Parts

Impeller casting parts serve as the core rotating elements in fluid machinery, converting mechanical energy into kinetic energy to drive liquids or gases. Produced through advanced lost-wax or die-casting techniques, these components feature aerodynamically optimized vanes for maximum efficiency. Constructed from wear-resistant alloys like 316L stainless steel or nickel-aluminum bronze, they withstand erosive and corrosive media while maintaining dimensional stability under high rotational speeds. These precision-cast impellers are indispensable in industries requiring reliable fluid transfer, from chemical processing to energy generation.

Core Processing & Customization Services

Silica Sol Investment Casting + CNC Machining Process

Model IMA011 impeller casting parts adopt the integrated process of silica sol investment casting and precision CNC machining, which is the core technology to ensure the dimensional accuracy and structural integrity of the product. The casting process strictly follows the standards of CT4-CT7/GBT6414-1999 and VDG Merkblad P690, realizing the minimum thickness of 2mm and the micro-region thickness of 1mm. The subsequent CNC machining includes turning, milling, drilling, boring and other processes, which can accurately process the blind holes with a maximum depth of 30mm and a diameter of 10mm, meeting the complex structural requirements of fluid machinery.
