Die casting for home appliances

As an innovative manufacturer of appliance components, we develop and produce high-quality die-cast parts that are model-specific and custom-tailored to your product.

Today’s home appliances must strike a balance between functional technology, sophisticated design, and long-term durability. Consumers purchasing appliances for their homes – whether coffee machines, washing machines, ovens, or refrigerators – expect more than just technical reliability. They expect a premium surface feel and a stylish appearance. For manufacturers, this means every component – visible or hidden – must meet the highest standards.
HDO has been a trusted partner in the home appliance industry for many years, delivering precision aluminium and zinc die-cast components along with a full-service offering – from development and manufacturing to advanced surface finishing.

Custom components for versatile applications

Whether primary parts, replacement components, or accessories: HDO die-cast parts are used in a wide range of well-known branded products, serving a variety of functions. Our components include:

Control knobs for ovens
Profiles and hinges for refrigerator shelving systems
Covers and decorative elements for coffee machines
Door rings and switch elements for washing machines and dryers

These parts influence the user experience beyond their functional roles. Control knobs, for example, convey a sense of quality and precision through their tactile feel. Profiles must remain mechanically reliable for years without losing tension. Visible components like covers or decorative parts need to integrate seamlessly into the overall design while staying durable, easy to clean, and visually appealing.

Zinc die casting – ideal for home appliances

Over the years, zinc has proven an excellent material for home appliance applications. It enables the production of precise, detailed geometries with consistent dimensional accuracy – even in high-volume runs. Zinc die-cast parts are also stable, impact-resistant, wear-resistant, and temperature-resistant – crucial qualities for products like ovens and washing machines.
Additionally, the zinc die casting process delivers high-quality surfaces even in raw form. These surfaces provide the perfect foundation for subsequent finishing processes such as electroplating, painting, or PVD coating – meeting both decorative and functional requirements.

From development to series production – expertise from a single source

At HDO, quality begins long before the casting process. In the early development phase, our experts support you with die-cast-optimised design, advising on the integration of functional features and refining geometries for cost-effective and stable series production.
With modern simulation software, we analyse casting behaviour, fill patterns, and potential distortion risks – allowing us to proactively address design challenges before tooling begins. Working closely with each of our clients, we develop precise solutions tailored to the specific requirements of each appliance model.

Premium surfaces for long-lasting quality

A key quality factor for appliance components is a refined surface finish. This is especially true for visible parts like knobs, door rings, or decorative panels, where a smooth, durable, and visually appealing surface is essential. HDO offers a wide range of finishing options – from high-gloss chrome or dark design electroplated coatings to scratch-resistant powder coatings and speciality PVD finishes.
Our highly automated production processes – combined with the extensive experience of our team – ensure consistent quality, efficiency, and cost-effectiveness across both high-volume production and smaller, design-driven product lines.
