Product Introduction
Our custom billet aluminum impellers are fully 5-axis simultaneous CNC milled from solid aluminum bar, serving as core rotating parts for turbochargers, centrifugal compressors, industrial blowers and high-speed fluid equipment.
Different from cast impellers, solid billet machining delivers higher structural integrity, fewer internal defects and better dynamic stability under ultra-high rotating speed. The one-setup 5-axis machining precisely forms complex twisted blade profiles, smooth flow channels and hub features, greatly reducing airflow turbulence and improving compression efficiency while lowering noise.
We mainly adopt 7075-T6 / 2618 aluminum alloy for turbo applications, featuring lightweight, high specific strength and good thermal conductivity. Every impeller can be processed with dynamic balancing test to ISO 1940 standard (G2.5 / G6.3 optional), which suppresses vibration, protects bearings and extends the service life of the whole machine.
We support full OEM customization according to your STEP, IGES or 2D engineering drawings: custom inducer/exducer diameter, blade quantity, blade angle, hub size, bore specification and surface treatment. Available finishes include sandblasting, clear/colored anodizing, hard anodizing, polishing and laser marking. Our service covers prototype testing, small-batch trial and mass production for automotive performance turbo, industrial air compressor, blower and new energy fluid systems.
