RuiYu provides complete die casting services for global OEM and ODM customers, covering custom mold engineering, high-pressure aluminum and zinc die casting, secondary precision CNC machining, custom surface finishing, and sub-assembly. Supported by over two decades of technical and quality control expertise, we turn complex design requirements into reliable, production-ready metal components with full process transparency.ensure a smooth transition into production. Feel free to contact our engineering team for a preliminary design review and tooling feasibility assessment
We support customers from initial product concepts through rigorous DFM (Design for Manufacturability) analysis, mold structure optimization, and flow simulations using advanced CAD/CAM software. By evaluating wall thickness uniformity, parting line placement, draft angles, and potential shrinkage early, our engineering team eliminates casting defect risks before steel cutting, ensuring long mold service life and smooth transition into mass production.
Backed by our 20+ years of tooling & quality control experience, strict quality management is integrated into every production stageHigh-efficiency aluminum and zinc die casting services are provided for diverse industrial and commercial applications. Supported by flexible production capabilities ranging from 38T to 800T+ hot-chamber and cold-chamber machine tonnages, we easily accommodate both small-batch prototype validation (10–500 pcs) and high-volume manufacturing runs. Aluminum Alloys: ADC12, ADC10, A380, A360, AlSi12, AlSi9Cu3. Zinc Alloys: Zamak 3, Zamak 5, Zamak 2.
For features requiring tight tolerances and critical mating fits, secondary multi-axis precision CNC machining operations are seamlessly integrated into our process. We coordinate CNC turning, 4-axis milling, high-speed drilling, tapping, and precision reaming to achieve strict dimensional accuracy down to $\pm0.01\text{ mm}$, ensuring perfect mechanical fit and functional performance for every component.
To meet severe environmental and decorative requirements, we manage complete surface finishing solutions and custom packaging. Secondary operations include shot blasting, precision grinding, vibratory polishing, anodizing, electroplating, e-coating, and high-durability powder coating—followed by structural sub-assembly, thread inserts installation, and custom export packaging ready for immediate use.
