Die Casting for Bathroom Fittings

Expert die casting for bathroom fittings – crafted to shine: As a manufacturer of metal components for the sanitary sector, we support brands that represent exclusive lifestyles.

Few industries combine technical functionality, high-end design, and demanding environmental conditions as directly as the bathroom and sanitary market. Premium taps, shower systems, and flush plates must deliver reliable performance while meeting the highest aesthetic standards – day in and day out, for many years, under exposure to moisture, cleaning agents, temperature fluctuations, and continuous use. HDO is your experienced partner in manufacturing such high-performance components. We offer a unique combination of die casting expertise, surface finishing, and manufacturing precision – perfectly aligned with the specific requirements of the sanitary industry.

Zinc die casting – HDO sets new standards for bathroom fittings

Zinc die casting has long been established as the process of choice in the sanitary sector. Its high dimensional accuracy, mechanical strength, and excellent surface quality make zinc ideal for bathroom applications. HDO harnesses this potential to the fullest: Our production processes are designed to manufacture exclusive components – such as tap handles and levers, housings and frames for shower systems, and design elements for flush plates – with the highest precision.
Thanks to our extensive development and design experience, we can make critical contributions early in the product development phase. By considering all downstream processes – such as surface finishing – we optimise components for efficient series production. The result: integrated solutions that are not only functional and economical, but also seamlessly fit into the premium design of modern bathrooms.

Premium surfaces – where function meets aesthetics

A standout feature of HDO’s bathroom components is their exceptional surface quality. With our fully automated die casting electroplating line and complementary technologies such as PVD, CDC, wet painting, or powder coating, we offer our clients a wide range of finishing options that meet the highest demands in gloss, feel, and durability.
This is particularly essential in areas like sinks, bathtubs, and showers – where splashing water, high humidity, temperature shifts, and frequent cleaning put metal surfaces to the test. Our coatings ensure long-term resistance to corrosion, colour fading, and scratches, while delivering brilliant, decorative appeal. From high-gloss chrome to matte finishes, brushed metal looks, or dark styles like Dark Chrome – we realise a broad spectrum in-house, including custom colours based on your design specifications.

Design-driven solutions for premium brands

As a partner to many leading bathroom and sanitary brands, we understand that design is no longer just an aesthetic feature – it’s a key differentiator. Consumers increasingly expect premium, stylish products that integrate seamlessly into personalised bathroom environments. HDO helps manufacturers of fittings meet expectations for form, colour, and function – without compromise.
With our combination of technical development support, advanced production systems, and first-class surface finishing, we provide solutions that fulfil even the most demanding design requirements. Our components impress not only with their functionality and durability but also with their visual and tactile appeal – which is crucial for creating a cohesive look in high-end bathrooms.

Process reliability and serial production expertise

When it comes to series production, process stability and repeatability are essential. HDO manufactures sanitary components on automated die casting lines using fully certified processes. Advanced measurement technologies and systematic quality control ensure consistently high standards – even for large production volumes and long-term projects.
Our in-house development team ensures short lead times and precise alignment with customer-specific requirements. This forms the basis for durable and cost-effective series production – whether for large part volumes or smaller product lines in the premium segment.

HDO – sustainable and responsible bathroom fittings

Sustainability is becoming increasingly important in the sanitary industry – for both end customers and manufacturers. HDO meets this demand with environmentally friendly, resource-efficient production methods. Our electroplating processes are free of organic solvents, diffusion-tight, odourless, and free from overspray. This reduces emissions, protects the environment, and supports your compliance with increasingly strict sustainability regulations.

Moreover, our die-cast components are fully recyclable, actively contributing to the circular economy. HDO takes a holistic approach to die casting and surface finishing. If you’d like to experience what that means in terms of outstanding customer service, get in touch with us today!
