Four processes covering the full R&D prototyping workflow

From appearance validation to structural assembly, from single prototypes to low-volume trial production, Deyou's process combinations meet the needs of different R&D stages.

⚙️

CNC Machining

20+ CNC machines covering milling, drilling, and side-milling, with same-day response for standard specifications.

  • CNC machining centers: brands including Xiongqun / Lidiao
  • Max machining envelope 1400×2000×300 mm, tolerance ±0.05 mm
  • Supports plastics (PC/ABS/POM, etc.) and metals (aluminum alloy / zinc alloy, etc.)
  • 30+ tons of material in stock; standard materials responded to same day
🪞

Manual Polishing

Experienced technicians hand-finish parts to ensure surface smoothness and fitment accuracy of cosmetic components.

  • Three-stage process: rough grinding → fine grinding → polishing
  • Ideal for appearance-critical parts such as lamp housings, bumpers, and interior trim
  • Integrates smoothly with CNC to avoid damage from secondary fixturing
🎨

Professional Painting

High-gloss black, plating-grade, and flame-retardant PC/ABS painting processes with high color consistency.

  • Supports high-gloss black, plating-grade, flame-retardant PC/ABS, and other process requirements
  • Flexible color matching; customer color swatches or Pantone numbers accepted
  • Dust-free paint booth to avoid particulate contamination

Screen / Pad Printing / Laser Engraving

One-stop marking service for characters, logos, QR codes, and serial numbers.

  • Screen printing: flat characters and color-block markings
  • Pad printing: small curved-surface graphics and characters
  • Laser engraving: permanent markings, serial numbers, QR codes
  • 30W fiber laser marking machine, suitable for both metal and plastic
Standard Process

From drawing to part in six steps

Requirement Consultation

Clarify purpose (appearance / structure / assembly), material, quantity, lead time, and acceptance criteria.

Drawing Evaluation & Quote

Assess process feasibility, provide process advice and a quote, then confirm and authorize.

Programming & Machining

CNC programming or 3D printing slicing, then execute machining/printing.

Post-Processing

Polishing, painting, screen printing, anodizing, and other surface treatments to enhance appearance and feel.

Quality Inspection

Dimension checks and appearance inspection, with inspection records provided when needed.

Delivery & Review

Packed shipment or client factory visit; collect feedback to optimize the next prototype.
