Simultaneous 5-axis machining for complex automotive geometries, from prototypes to repeat production.
DekAutomotive machines complex vehicle parts on 5-axis equipment, including EV housings and structural components. Parts are made under an ISO 9001-certified quality system. CMM inspection and FAI reports are available on request.
Maximum Diameter
Tolerance Accuracy
Surface Roughness
Utilizing high-speed simultaneous 5-axis machining centers, DEK Automotive maintains precise control over intricate automotive geometries. Our facility integrates multi-axis synchronization to reduce setups, ensuring consistent dimensional accuracy for engine internals and large-scale EV structural components.
Complete Multi-Sided Machining
Deep Cavity Access
Tool-Path Repeatability
Our 5-axis capabilities resolve complex undercut challenges and deep cavity milling where conventional 3-axis systems fail. By optimizing tool paths for thin-walled housings and aerodynamic impellers, we minimize thermal stress and guarantee the geometric precision required for mission-critical automotive assemblies.
Metals & Plastics
High-Speed Spindle
Thin-Wall Precision
We routinely machine demanding materials ranging from high-strength 7075 aluminum to titanium and specialized superalloys. Our process focuses on maintaining dimensional integrity for thin-walled components, ensuring every workpiece meets the rigorous durability and weight-reduction targets required for modern propulsion systems.

We maintain ±0.01mm flatness on EV housings with wall thicknesses under 1.0mm by utilizing specialized vacuum fixtures and stress-relieving tool paths.
Simultaneous 5-axis linkage enables single-setup machining for aerodynamic impellers, eliminating the 0.05mm alignment errors caused by traditional multi-step re-clamping.
Deploying specialized carbide tooling and high-torque spindles, we sustain ±0.005mm tolerances on high-strength titanium and 7075-T6 aluminum components for mission-critical assemblies.
For steering systems requiring high concentricity, we integrate CMM-verified in-process probing to ensure positional accuracy remains within 0.003mm across every production batch.
Process controls and CMM checks are used on the dimensions the drawing calls out. Parts are made under an ISO 9001-certified quality system.

DEK Automotive provides expert technical support from DFM analysis to full-scale production, utilizing over 15 years of precision manufacturing experience to optimize complex automotive component designs.
"You guys at DEK Automotive really saved our season with those customized 5-axis wheel uprights and suspension clevises. The blue anodizing you did was spot on without a single scratch, even though the shipping took a day longer than I’d hoped because of customs. You packed them so tightly I spent ten minutes fighting the bubble wrap to get them out, but at least every component arrived in perfect tolerance.”

"These aluminum battery coolant manifolds and motor housings are top-tier with clean edges and very sleek bead blasting. It is honestly hard to find a shop in Shenzhen that handles the documentation and technical specs this well. Thank you!”
Senior Procurement Manager, EV Systems
"I am impressed with the 5-axis precision you achieved on our stainless steel fuel rail prototypes and turbocharger impellers, especially those complex undercuts. I was a bit surprised by how many technical questions your engineers asked during the DFM phase, but your attention to detail caught a major clearance issue we missed!”
