Zhigu's alloy wheel factory specializes in aluminum-magnesium/silicon alloy wheel production, offering both cast and forged solutions. The forged alloy wheels, crafted from 6061-T6 aluminum via 5000-ton hydraulic forging presses, feature a dense molecular structure that enhances strength by 40% and reduces weight by 30% compared to cast wheels. The cast alloy wheels, produced through low-pressure casting, balance cost-effectiveness with durability for daily-use vehicles. The factory's production line includes 20 CNC machining centers, 15 automatic painting booths, and 5 non-destructive testing stations. It supports monoblock, 2-piece, and 3-piece constructions, with customizable PCD (4-12 holes), CB (56.1-120.65mm), offset (-25 to +50mm), and finishes like powder coating, diamond cutting, and chrome plating. As an OEM supplier for three major automakers, the factory ensures each alloy wheel meets JWL/VIA standards and undergoes 72-hour salt spray testing for corrosion resistance.
