5. FAQ

Q1: What is the benefit of using CNC after die casting?
A1: CNC machining ensures high precision for critical features such as threads, flatness, and tight tolerances not achievable through casting alone.

Q2: Can I customize the surface treatment color and texture?
A2: Yes. We offer custom RAL color matching, matte/gloss levels, and textures including brushed, bead-blasted, and polished finishes.

Q3: How durable is the surface treatment?
A3: Anodized and powder-coated parts can withstand up to 1000 hours of salt spray testing. We follow ASTM and ISO standards for durability.

Q4: Do I need to use multiple suppliers for machining and coating?
A4: No. We offer a fully integrated solution including die casting, CNC finishing, and all major surface treatments—saving time and cost.

Q5: What’s the typical lead time for a new part?
A5: Prototypes can be ready in 5–7 days. Mass production generally takes 15–30 days depending on volume and complexity.

Q6: Can you provide design support for manufacturability?
A6: Absolutely. Our engineering team assists with DFM analysis to ensure optimal casting, machining, and surface finish performance.
