At Shenzhen Alu Rapid Prototype Precision Co., Ltd., established in 2010, we are pioneers in advanced manufacturing solutions, specializing in CNC machining, aluminum die casting, vacuum casting, 3D printing, injection molding, and sheet metal fabrication. Our commitment to innovation has led to a groundbreaking technological breakthrough in pure aluminum die casting—overcoming the long-standing challenges of traditional alloy-based methods, particularly in surface coloring and anodizing.

Traditional aluminum die casting relies on alloys like ADC12 or A380, which include silicon, copper, and other elements for better castability. While effective for strength and fluidity, these alloys severely limit post-processing options. High silicon content often results in dark, uneven oxide films during anodizing, making vibrant, consistent coloring nearly impossible. This restricts designers in industries demanding premium aesthetics, such as consumer electronics, automotive trim, lighting, and high-end product enclosures.

Our pure aluminum die casting technology changes everything. By utilizing high-purity aluminum, we eliminate impurities that interfere with surface treatments, delivering parts that excel in anodizing and coloring:

1.Superior Anodizing and Coloring Capabilities: Achieve clear, vibrant, and uniform anodic oxide films with excellent dye absorption. From brilliant reds and blues to sleek metallic finishes, our parts support a full spectrum of colors that are durable, scratch-resistant, and fade-proof.

2.Enhanced Aesthetics and Functionality: Parts with mirror-like polish, high reflectivity, and flawless decorative finishes—perfect for products where appearance is as critical as performance.

3.Improved Properties: Higher thermal and electrical conductivity, better corrosion resistance, and a denser natural oxide layer compared to alloyed alternatives.

This innovation unlocks new creative possibilities for product designers and manufacturers. Whether you're developing sleek smartphone housings, elegant lighting fixtures, EV components, or premium consumer goods, our pure aluminum die cast parts combine precision thin-wall casting with stunning, customizable surfaces—meeting the evolving demands for both functionality and beauty.

From rapid prototyping to full-scale production, we provide one-stop solutions tailored to your needs. Our experienced team ensures seamless support from design optimization to final delivery.
