FAQs

Yes, we can customize aluminum machining according to customer drawings or design requirements. Whether for mass production or one-off custom parts, we can meet your needs.

Common surface finishes include anodizing, plating, sandblasting, and polishing. These finishes can provide additional corrosion resistance, aesthetics, or enhanced strength depending on the requirements.

We use high-precision CNC machines and strict quality control processes, our five-axis CNC machining can achieve the highest precision of 0.015mm. In addition, we also have high-precision inspection equipment to inspect and test products. For example, our three-dimensional coordinate tester can reach 0.3μm, which is inspected to ensure that each aluminum component meets the required standards.

The lead time depends on the complexity, size, and machining techniques used. For simple prototypes, we can typically complete them within 1-3 days.

The cost of CNC machining aluminum is influenced by various factors. As a supplier with a complete supply chain, we have full control over the material sourcing, machining processes, and production management. By managing the entire production workflow, we can maximize material efficiency, optimize processes, and reduce costs associated with intermediaries. This allows us to offer more competitive pricing to our customers, ensuring lower costs without compromising on quality.
