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.
