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.

Zeiss CMMs verify ±0.5μm dimensional tolerance; laser interferometry ensures flatness/parallelism ≤0.005mm/m.
2
Surface & Cleanliness
Profilometer checks Ra≤0.02μm (wafer stages); ISO 14644-1 Class 5 testing limits particles ≥0.5μm to ≤1/ft⊃3;.

3
Material Validation
XRF analysis confirms alloy purity (e.g., Invar); leak testing validates vacuum components (≤1×10⁻⁹ Pa·m³/s) .
4
Traceability & Documentation
Full material certs, inspection logs, and test reports archived for 10+ years to meet audit requirements
FAQs

What key challenges exist in semiconductor part manufacturing?

A: Semiconductor manufacturing demands sub-micron tolerances, ISO 8 cleanroom standards (low particle counts), and complex material processing (e.g., stress control for titanium/Invar alloys)—all while delivering fast turnaround for low-volume, high-variety parts.

How do you ensure cleanroom compliance?

A: We use ISO 8-certified workstations, perform Class 100 cleanroom cleaning (particles ≤5μm), and apply low-outgassing surface treatments. All materials and processes include 10+ year traceable documentation (certs, logs) to meet industry audit requirements.

Can you manage materials with strict traceability?

A: Yes. We source specialized metals (316L, Invar, titanium) and plastics (PEEK, PTFE) with batch-level traceability. Every part is accompanied by material certificates and process records to ensure full semiconductor industry compliance.
