With 60 years of experience to date, we have not only been able to establish ourselves as a specialist for die casting with high-quality surfaces but, first and foremost, as a reliable partner for customers from the most diverse and demanding sectors, such as the automotive or sanitary industries.
As an international family-owned business based in Germany, we have been able to maintain our position as the European market leader for decorative metal die casting for many years. The mapping of all manufacturing processes, from the initial request to the refined series component, is what distinguishes us from our competitors. Brilliance in each and every aspect is our ambition, motivation, and promise.
HDO is a family-led group of companies with three international locations and approximately 900 employees. Since its foundation in 1956, the headquarters of the HDO Group has been located in Paderborn,Germany. The employees in this competence and development centre are responsible for all processes involving die casting technology and surface engineering.
The positive synergy effects of our international position become apparent, firstly, in our distinctively efficient overall approach. Secondly, through the “one face to the customer” convenience for our customers. From the initial inquiry to series manufacturing, all processes are in-house – and the customer has a single point of contact.

“We’d love to…!” – this is our most frequent business response to customer inquiries. This is because our objective is not just customer satisfaction but rather customer inspiration. Furthermore because we simply like to do our best, as a competent partner as well as in the form of brilliant solutions and products.
Our dedication for excellence keeps us constantly active internally as well. The whole HDO Group is in a state of continuous business development. No entrenched processes, no outdated ways of thinking, but instead an agile drive for sensible optimisation at each and every level. In this way, we stay true to both ourselves as human beings as well as to our business code of conduct.
There is a distinct common thread throughout our decades-long success story: the continual search for new technologies and products. This important factor of our success continues to be a focal point of our activity.
The Westfälische Metallindustrie (WMI) company, which later became Hella, founded its Plant 3 in Paderborn, consisting of a foundry and a grinding shop. The die cast manufacturing of zinc products began.
1960s
The first fully automated electroplating system was put into operation, which made it immediately possible to produce electroplated parts as well. In addition, the construction of the new foundry hall allowed for an expansion of the production capacities.
1970s und 1980s
The green light for the initial mixing of sectors occurred with the first delivery to the sanitary and consumer goods industry. A short time later, new computer-aided production technologies were deployed: CNC technology as well as the use of robots in the foundry were further important steps towards technological progress and automation.
1990s
With the delivery of the washing machine ring, we started to successfully establish ourselves in the household appliance industry. At the same time, the HDO Group was starting to form: The HDO Druckguß- und Oberflächentechnik GmbH company was founded from the die casting division of Plant 3, while in the Czech Republic the HDO spol. plant was built for the outsourcing of labour-intensive activities.
2000s
The time had come to expand the service portfolio: the HDO Service GmbH company was founded in Paderborn and the HDO SK s.r.o. in Slovakia. The executive floor became a family matter – Werner Beneken became sole owner of the HDO Group.
To the present day
The founding of the Innovation Management division has allowed for the targeted identification of new market requirements and the corresponding adaptation of technologies and products. The repositioning of the company allowed for the development of new market segments. HDO has become an innovative development partner for its customers.

For us it’s completely obvious: employees are the most important factor in business success. However, the satisfaction of each individual is a top priority not just from a business point of view but also from a human perspective.
With exciting, responsible tasks, flexible working hours, and individual support, we provide everybody the space for development. Flat hierarchies and short decision paths enable each and every employee to become invested and participate in the joint success.
We know that: a strong sense of unity arises from satisfaction, which turns our employees into highly committed human beings who are deeply rooted in the company and who strive with all their might for joint success. Therefore, our employees’ satisfaction is our top priority.
We gladly take on the challenges of the increasing digitalisation of the economy and society. Moreover, we actively participate in the design of these rapid developments. We are, for example, contributing our power of innovation to the concrete design of the “touch-free” generation or of “Industry 4.0”.
The prerequisite for this is a high degree of networking in process design, which we are continuously working on. Thanks to our efficient innovation management and our strong motivation, technologies of the future become tangible today, for smart production solutions – today and tomorrow.
HDO’s technological expertise focuses on the production of decorative castings made from zinc and aluminium alloys. The die casting process enables us to manufacture complex metal components economically and precisely with very high dimensional accuracy, outstanding strength and excellent surface quality. HDO manufactures die cast products for a wide range of industries and in numerous variants – from small, delicate components for car keys to large housings for industrial applications.
Thanks to our extensive machinery, many years of process expertise in die casting and surface finishing, and in-depth understanding of materials, we at HDO are able to manufacture both small and large series efficiently and reproducibly. We use automated casting cells, continuously monitor the entire production process digitally and, in addition to highly automated technology for quality assurance, draw on the expertise of our experienced development staff, who optimise every component from the outset for manufacturability and maximum production quality.
A key factor in HDO’s success is the early involvement of our development and design department in supporting our customers. We are on hand to advise our clients right from the conception phase. Whether it’s design optimisation, functionally integrated component design or simulation of casting processes, HDO offers in-depth expertise for the implementation of technically sophisticated and decorative components.
With the help of casting simulations, thermal analyses and tool-compatible geometry adjustments, we ensure that the final component can be cast economically while also meeting the highest standards of functionality and quality. This development approach saves time, reduces iteration loops and significantly increases process reliability in series production.
As a service provider for customised die-cast parts with exceptional vertical integration, right through to coated components, HDO has its own in-house surface finishing facility. We operate Europe’s largest fully automated electroplating facility for zinc die casting and other materials such as brass, steel and stainless steel, offering an unrivalled range of coating processes. These include electroplated surfaces such as high-gloss and pearlescent chrome; dark chrome colours such as Dark Chrome or customer-specific electroplated colours. Powder coating, wet painting and cathodic dip coating (KTL) as well as PVD coatings for special decorative layers are also possible. We are also happy to provide laser engraving, embossing and hygienically germ-free surfaces on request.
Our finishing processes meet both functional requirements – such as corrosion protection, scratch and UV resistance – and the highest visual standards in the visible range. They are used wherever components must not only be mechanically reliable but also of high design quality – for example, in the automotive industry, in household appliances or in the sanitary sector.
HDO supplies a wide range of industries, each with their own specific requirements. This diversity makes the company particularly flexible and adaptable. Its core industries include the automotive industry, where HDO supplies components such as door interior controls, trim strips, components for vehicle keys and gearshift paddles. In sanitary engineering, it produces handles, levers and housings for fittings, toilet flush plates and frames and housings for shower systems. For manufacturers of household appliances, HDO produces control knobs, door rings for washing machines, covers for fully automatic coffee machines and profiles for refrigerator shelf systems, among other things. The medical technology sector also benefits from the company’s expertise, for example through handles, housings and components for medical and veterinary equipment. In industrial and building technology, products such as displays and frames for door access and smart home systems, housings for machine controls and components for industrial cameras are used. In addition, HDO supplies the agricultural and construction machinery industry with particularly robust housings and instrument covers that require high resistance. Thanks to this broad focus, HDO can leverage synergies from various projects and further develop innovations across industries.
At HDO, quality is anything but a matter of chance. Production is certified according to international standards such as IATF16949, ISO 50001 and ISO 14001. Our certified management systems ensure consistent part and process quality across all areas of the company.
Every component undergoes comprehensive testing and quality assurance measures – from initial sample testing in the time-to-market process to final inspection in series production. In addition to high part quality, we place particular emphasis on sustainability. Our goal is therefore the sustainable manufacture of high-quality, environmentally friendly and health-compatible products while conserving resources. To achieve this, we use a wide range of measures as part of our integrated environmental and energy management system. For example, we use only recycled zinc and aluminium in our foundries to ensure a sustainable circular economy, employ energy-efficient equipment and use unused or surplus energy from our production wherever it is needed. The electroplating process is also low-emission, free of organic solvents and without overspray.
These and many other measures make HDO a reliable partner for customers from a wide range of industries.
Whether zinc or aluminium: with decades of experience in die casting, technological leadership and a comprehensive range of services, HDO from Paderborn is the ideal partner for all companies that rely on high-quality, durable and aesthetically sophisticated metal components. From die-cast-compatible design to the perfect surface finish – at HDO, all processes are seamlessly integrated. Customers benefit from sound advice, maximum process reliability and the certainty of having a partner at their side for whom the highest quality standards are part of everyday business.
