Weifang Yili Precision Casting manufactures turbocharger and turbine components using lost wax investment casting, vacuum casting, and five-axis machining with strict inspection and traceable process control.
Weifang Yili Precision Casting Co., Ltd specializes in precision components produced through lost wax investment casting, vacuum casting, and five-axis machining. The company supplies a broad range of high-performance parts including turbine wheels, compressor wheels, turbine blades, nozzle guide vanes, nozzle rings, diffusers, and housings.
Its manufacturing focuses on turbocharger parts for cars and trucks, as well as applications for marine and locomotive turbochargers. The product scope also extends to aviation turbojet engine spare parts and components for gas and steam turbines, alongside heat-resistant and corrosion-resistant superalloy casting parts used in oil, gas, chemical, pump, and compressor systems.
With extensive heat-resistant alloy vacuum investment casting experience, the company uses a pure silica sol shell process and emphasizes consistent quality control by recording the full production process. Inspection is integrated from incoming materials through first article, in-process checks, and final inspection, supported by non-destructive and destructive testing capabilities, including fluorescent penetrant testing, radiography, tensile and creep testing, metallography, hardness testing, chemical composition analysis, and CMM dimensional measurement.
Produces heat-resistant and corrosion-resistant superalloy casting parts for demanding applications, including impellers and turbine blades for oil, gas, chemical, pump, and compressor equipment.
Uses a pure silica sol process for shell making, with selected wax and zircon powder and sand for stable, repeatable casting quality.
Strictly controls and records the complete casting production process to ensure every delivered product meets quality requirements.
Supports precision field surveying and mapping for samples, and converts drawings into 3D modeling to enable customized production.
