01

5-Axis Machining

Executing complex geometries in single setups, achieving ±0.01mm repetitive positioning for critical automotive structural components.
02

CNC Milling

We combine precision CNC milling, engineering-grade materials, and controlled finishing processes to manufacture automotive components with stable quality, tight tolerances, and reliable production consistency.
03

CNC Turning

We combine precision CNC turning, engineering materials, and controlled finishing processes to manufacture automotive rotational components with stable tolerances and reliable production consistency.
04

Shaft Machining

We combine precision turning, grinding, and inspection processes to manufacture automotive shafts with stable rotational accuracy and reliable production consistency.
05

Complex Parts Machining

We combine multi-axis machining, geometry-driven process control, and precision inspection to manufacture complex automotive components with stable fit and reliable assembly performance.
06

Hard Material Machining

We machine hardened steels and advanced alloys using rigid systems designed to maintain geometry stability under extreme cutting resistance and thermal stress.

Why us

Why engineering teams choose DekAutomotive

Complex, high-mix parts

Automotive precision parts: multi-face housings, cooling plates, cast components, parts still in revision.

Repeatability

One process route, fixture set and inspection plan per part, kept from pilot to repeat production.

Inspection & traceability

CMM reports, FAI reports and material traceability on request, not a certificate of conformity alone.

DFM and cost review

Custom CNC auto parts reviewed for process route and cost before the first chip is cut.

What automotive parts does DekAutomotive machine?

Precision housings, brackets, cooling plates, heat sinks, shafts and structural parts for EV, ADAS, electronics, thermal, powertrain and chassis applications, always to the customer's drawing.

What quality documentation do you provide?

On request, we supply the documents your program needs: CMM dimensional reports, FAI and inspection reports and mill test reports for material traceability. PPAP-style documentation on request (to validate by DEK). Parts are made under an ISO 9001-certified quality system.

Do you handle high-volume series production?

We focus on engineering samples, pilot builds, low-volume and repeat production of complex parts; we are not set up for fully automated mass production.

What is your minimum order quantity?

From single engineering samples to low- and mid-volume repeat batches.

What tolerances can you hold on automotive machined parts?

As tight as ±0.02 mm, depending on the feature and the material.

How fast do I get DFM feedback?

Within 24 hours of receiving complete drawings.

Do you design parts or only build to print?

We manufacture to customer drawings and support DFM; we do not design vehicles or assemblies.
