Dakings delivers high-precision automotive parts across engines, chassis, and body systems. We specialize in complex geometries, rapid turnaround (critical for automotive’s fast cycles), and IATF 16949-compliant processes—supporting OEMs and suppliers with diverse needs, from 5-axis machined engine parts to 3D-printed plastic prototypes.

Automotive Manufacturing Capabilitie

Processes for Every Automotive Component
  • 5-Axis CNC Machining
    Handles engine components (intake manifolds, crankshafts) with complex geometries — ensuring precise angles (±0.01°) and surface smoothness (Ra ≤0.8μm) for optimal performance.
    SUBMIT
  • Stamping & Sheet Metal
    Produces body panels (304 stainless steel) with seamless curves; welding for structural integrity, meeting strict surface standards (no wrinkles or scratches).
    SUBMIT
  • Plastic Prototyping
    3D printing for opaque parts (ABS, PA) with rapid turnaround; CNC machining for transparent parts (PMMA) with hand polishing—guaranteeing clarity for lenses/covers.
    SUBMIT
  • Surface Treatments
    Nitriding (crankshafts for fatigue resistance); hard anodizing (aluminum brackets for wear); powder coating (body parts for corrosion protection).

Why Choose Us

Why Choose Dakings for Automotive Manufacturing?

Project Expert Team

 
  Our team averages 10+ years in automotive machining, operating 5-axis CNC centers and precision stamping equipment. We handle complex parts—from 7075 aluminum engine manifolds (±0.005mm tolerance) to 304 stainless steel body panels—ensuring high quality across engines, chassis, and interior components.
 

Customized Solutions

 
We tailor services to automotive needs: design optimization (anti-wrinkle for body panels) to scalable production. Whether prototyping 3D-printed plastic parts or ramping to small-batch engine components, we adjust processes to meet fast cycles and fit requirements, accelerating your launches.
 

Strict Quality Control

 
Backed by IATF 16949, our process includes raw material inspection (certified metals/plastics), in-process checks (surface smoothness, angle precision), and traceable documentation. Every part meets OEM standards for safety-critical components.
 

Precision Inspection

 
Equipped with Zeiss CMMs, Marr projectors, and Mitsutoyo gauges, we verify tight tolerances (geometric tolerances ≤0.005mm) and surface quality (Ra ≤0.8μm). Our 99.5% qualification rate ensures reliable performance in automotive systems.

FAQs

Can you manufacture complex automotive parts with tight tolerances?

Q: We need engine components (e.g., intake manifolds) and body panels with complex geometries and strict tolerances. Can Dakings handle these?
A: Yes. We leverage 5-axis CNC machining for engine parts (e.g., ±0.005mm tolerance on intake port angles) and 3-4 axis machining for body panels (ensuring wrinkle-free, seamless curves). For surface quality:Engine components achieve Ra ≤0.8μm (smoothness for optimal performance).Body panels undergo strict visual checks (no scratches, wrinkles). We also specialize in materials like 7075-T6 aluminum (engine parts, high strength) and 304 stainless steel (body panels, corrosion resistance), balancing precision and functionality.

What's your lead time for small-batch automotive production?

Q: We require small batches (50–500 units) of automotive parts with fast delivery. How quickly can you respond?
A: Our workflow is optimized for automotive’s fast cycles:

Prototypes: Ready in 24 hours (e.g., 3D-printed plastic dashboards, CNC-machined aluminum brackets).
Small batches: Delivered in 5–7 days for most parts (e.g., stamped body panels, 5-axis machined engine components).
We reduce delays by:
Grouping similar materials (e.g., aluminum profiles for multiple parts).
Streamlining processes (e.g., parallel surface treatment and inspection).
Even for multi-variety orders, we prioritize speed without compromising quality.

How do you ensure quality and IATF 16949 compliance?

Q: Our automotive parts need to meet IATF 16949 standards. What quality controls do you have?
A: We adhere to IATF 16949 for end-to-end quality and traceability:
Precision Inspection:
Zeiss CMMs verify dimensional tolerances (e.g., ±0.005mm for engine ports).
Projectors check flatness; Ra testing ensures surface smoothness.
Documentation:
Material certificates, first-article reports, and in-process logs are stored for audits.
Functional Validation:
Assembly trials confirm seamless fit; hardness tests (e.g., HRC 30–35 for 7075 aluminum) ensure material performance.
This rigor guarantees parts meet OEM safety and quality requirements.
