To our product ‘Automotive’

Sophisticated components for high-end vehicles

HDO manufactures a wide range of complex components for vehicles across various equipment levels, including the premium segment. Typical applications include:

Components for vehicle keys
Interior door handles
Decorative interior and exterior elements
Switch housings
Centre consoles

These parts are a visible part of the vehicle’s design – and a direct reflection of brand quality and manufacturing expertise. Accordingly, the expectations for dimensional accuracy, surface quality, and mechanical performance are high.

One partner for the entire process – from development to series production

HDO contributes its extensive know-how early in the design phase. Together with our customers, we develop geometries optimised for die casting that ensure stable and cost-effective series production. We take into account functional requirements – such as mechanical strength, integration of fastening elements, and dimensional stability – as well as follow-up processes like surface finishing and assembly.
Our goal is to create a solid foundation for quality, cost efficiency, and process reliability right from the development stage. This results in components that are precisely tailored for series production and meet the strict standards of the automotive industry.

Uncompromising precision in manufacturing

At HDO, production relies on a wide array of die casting machines, automated process chains, and continuous quality monitoring. Our manufacturing processes are designed to deliver large volumes with consistently high dimensional accuracy and repeatability. This is especially crucial for safety-related or high-stress parts – such as interior door handles or locking mechanisms. We ensure that all parts meet the required specifications across long production runs, even with the tightest tolerances.

Flawless surfaces – both functional and decorative

One of HDO’s key differentiators is our combination of die casting expertise and in-house surface finishing. We operate Europe’s largest fully automated die-cast electroplating line and offer a wide range of premium coating processes, including:

Decorative and technical chrome plating, nickel plating, and copper plating
Dark finishes such as Dark Chrome, Eclipse, Twilite, and Starlite
Electroplated custom colours tailored to automotive standards, such as 3Q7, Silvershadow, and Alulook
PVD coating, cathodic dip coating (CDC), powder coating, and wet painting

Interior automotive design requires outstanding tactile quality, precise colour matching, and the right balance between gloss and matte finishes. Our coatings are scratch-resistant, corrosion-proof, colourfast, and built to endure – even under heavy daily use. The perfect blend of function and aesthetics makes our components the go-to choice for premium vehicle interiors.
