CNC Machining, Fabrication & RFQ FAQ

Send 2D drawings, STEP/STP or other 3D CAD files, material, quantity, tolerance notes, surface finish, and application requirements. Clear sample photos can help early discussion.

Photos can start a discussion, but final quotation normally needs dimensions, material, quantity, and key tolerance requirements. For production, drawings or sample confirmation are usually needed.

Yes. The RFQ page supports multiple files, including CAD, PDF drawings, photos, and ZIP packages.

Hasun can review CNC milling, CNC turning, drilling, tapping, sheet metal fabrication, surface treatment, selected assembly, and related custom hardware manufacturing.

Common options include aluminum alloys, stainless steel, carbon steel, brass, copper, engineering plastics, and project-specified metals. Material choice should match strength, corrosion, weight, finish, and cost needs.

Prototype and batch production requests can both be reviewed. The most suitable process depends on drawing complexity, material, quantity, finish, and inspection requirements.

Please mark key dimensions, fit areas, surface requirements, thread requirements, and critical appearance zones. This helps the team understand what must be controlled before quotation.

First-article review can be discussed when a project requires dimensional confirmation before batch production. The exact inspection scope should be confirmed by drawing and order requirement.

Yes, cosmetic areas can be discussed. Buyers should define visible surfaces, acceptable marks, color requirements, and packaging protection expectations.

Typical finish discussions include anodizing, hard anodizing, polishing, brushing, sand blasting, plating, powder coating, and project-specific color or texture requirements.

Confirm base material, color, gloss or matte appearance, masking areas, threaded holes, cosmetic standard, and any corrosion or wear expectations.

Yes. Coating thickness, polishing, plating, and masking can affect fit and dimensions, so important surfaces should be marked clearly on the drawing.

Selected finished-product and assembly projects can be discussed, especially when they involve precision metal parts, structural components, hardware, and packaging support.

NDA requirements can be discussed before sharing sensitive drawings or product files.

Lead time depends on material availability, part complexity, quantity, finish, inspection scope, tooling or fixture needs, and packaging requirements.

Complete drawings, CAD files, material, quantity, finish, inspection notes, target application, and delivery expectations help reduce back-and-forth.
