Die casting for industrial and building technology

HDO for building systems and industrial applications: Benefit from the expertise of a specialist that has already produced numerous custom-engineered components for industrial and building technology with precision and excellence.

In industrial and building technology, components must deliver on functionality, design, and quality. Manufacturers expect durable, robust, and precisely manufactured parts that integrate seamlessly into larger systems while withstanding external stresses. HDO has been a trusted partner in this demanding field for many years. With our die casting expertise and advanced industrial surface finishing, we supply high-quality housings, covers, and connectors that fully meet the requirements of modern industrial and building systems.

Where function meets design – our components for building automation

For clients in industrial and building technology, HDO manufactures components such as:

Housings for control units, including machine control systems
Covers and frames for smart home control centres
Decorative frames and display bezels for door access systems
Components for industrial camera systems
Connectors and mechanical interfaces for industrial plugs

These components often serve a dual function: they must be mechanically robust and manufactured with precision to fulfil their technical purpose reliably, while also serving as visible design elements – at building entrances, in safety systems, or in smart home control units. This makes aesthetics just as important as technical performance.
With HDO, manufacturers benefit from a production approach that unites both: high dimensional accuracy, strength, and functionality – combined with attractively refined, high-quality surfaces.

Zinc die casting – the ideal solution for precision technology

Zinc die casting offers clear advantages in industrial and building applications. The process enables the creation of complex, finely detailed geometries with tight dimensional tolerances. Zinc provides excellent mechanical strength, tensile and elongation properties, temperature stability, and long service life.

Zinc die casting is especially effective for housings and connectors exposed to mechanical stress, environmental influences, or frequent handling. It also allows for the integration of fastening bosses, undercuts, hollow sections, and guiding elements directly into the cast component – reducing the need for secondary operations and combining multiple functions in a single part.

Surface finishing – technical protection with a premium look

One of HDO’s unique strengths is the combination of in-house die casting and surface finishing at a scale few can match. Our fully automated electroplating line – one of the largest in Europe – alongside processes like PVD coating, powder coating, cathodic dip coating (CDC), and wet painting, enables us to deliver surfaces that meet both protective and design-related requirements.

For industrial and building applications, this means our components are corrosion-resistant, temperature- and moisture-resistant, scratch-resistant, and visually refined. We produce chrome surfaces in a variety of gloss levels, premium dark tones like Dark Chrome, brushed metal effects, and custom colours according to client specifications – efficiently and in large volumes.

These surfaces are especially important for door access systems and visible control panels, where design plays a key role in reinforcing the brand and delivering a high-end user experience.

Process reliability and development expertise

HDO stands for collaborative development. From the design phase onward, we support clients in creating die-cast-optimised geometries – factoring in all manufacturing steps through to the finished, coated component. Using advanced simulation tools, we analyse filling behaviour, thermal distribution, and potential weak points – optimising part geometry for a stable series production.

Our clients benefit from fast response times, dedicated points of contact, and precise coordination of all processes tailored to the specific demands of each project. This forms the foundation for economically and technically reliable serial production – even for complex or high-stress components.

Performance, durability, and sustainability at the core

Components for industrial and building technology must function reliably for many years under varying environmental conditions, temperature changes, and humidity. HDO’s production processes are specifically designed for such long-term performance. Our die-cast parts are extremely durable, low maintenance, and easy to clean. Our surface finishes preserve their aesthetic and tactile quality over time – resistant to wear, fading, or surface degradation.

HDO is also a leader in sustainable manufacturing. Our production processes are certified to meet energy and environmental standards and are resource-efficient and recyclable. The zinc and aluminium alloys we use can be fully recycled without any loss of quality. Our surface finishing processes are low-emission and energy-efficient – adding value for customers who prioritise environmental responsibility and compliance with increasingly strict sustainability regulations.
