CNC machining auto car parts refers to manufacturing precision automotive components through CNC milling, turning, and multi-axis machining. Strongd serves global OEMs and suppliers, producing engine components, transmission housings, suspension parts, sensors, and custom brackets. From prototyping to high-volume production, we deliver certified solutions.
Advantages
Precision Manufacturing
CNC machining achieves tight tolerances critical for automotive performance:
Metal parts: ±0.01mm (e.g., aluminum engine blocks, gearbox shafts)
Plastic parts: ±0.05mm (e.g., intake manifolds, electronic housings)
Surface finish: Ra 0.4μm achievable
01
High Efficiency & Flexibility
50+ CNC machines: 3/4/5-axis machining centers
5-axis capability: Complex geometries (turbine blades, impellers) in single setup
Rapid prototyping: 3-7 days for functional samples
02
Material Versatility
Process metals (aluminum, steel, brass) and engineering plastics (PEEK, ABS, POM) with equal precision.
03
Applications
Prototype validation ensures design integrity before mass production. Critical applications include:
Powertrain: Gearbox casings, pistons
Electrification: Battery heat sinks, motor endplates
Chassis: Steering knuckles, shock mounts

04
Surface Treatment
Post-machining enhancements:
Metal: Anodizing (Al), zinc plating (steel), polishing
Plastic: Painting (RAL/Pantone), texture coating, laser engraving
Functional: Hardening, anti-corrosion coatings
05
Our AS9100/IATF 16949-certified engineers combine 15+ years of automotive expertise with advanced CAM software. We optimize designs for manufacturability (DFM), enforce strict quality control (CMM inspections), and ensure 98% on-time delivery. 85% clients return for repeat projects.
