Shenzhen Alu Rapid Prototype Precision Co., Ltd. Industry News Home News Die cast aluminum molds Key Considerations Alloy Choice: Common aluminum alloys for die casting include A380 (good strength and fluidity), A383, or A360, depending on the part’s requirements.Mold Longevity: Steel molds can last 100,000–1,000,000 cycles with proper maintenance, but high-volume production may require multiple molds.Cost: Tooling costs for aluminum die-casting molds are high (often $10,000–$100,000+), but they’re cost-effective for large production runs.Tolerances and Surface Finish: Die casting achieves tight tolerances (±0.05 mm) and smooth surfaces, reducing post-processing needs.
