About us – hollomet GmbH

Innovative solutions for lightweight construction, rigidity, and protection

How can weight be reduced without losing the necessary rigidity? How can rotating systems be made more agile? And how can mobile equipment be effectively protected against shocks? Hollomet GmbH provides answers to these questions — with innovative solutions based on metallic or ceramic hollow spheres and their composites.

Our cellular products are manufactured using modern powder metallurgical processes, which enable a wide range of materials to be used — from standard and special alloys to ceramic materials. We therefore see ourselves not only as a reliable supplier of high-quality components, but above all as a competent development service provider that works with its customers to implement tailor-made solutions.

Our vision

At hollomet GmbH, we have set ourselves the goal of rethinking materials and developing them into innovative products. Our solutions are designed to optimize the performance of your applications while reducing environmental impact.

Our open-cell metal foams (foamet®) open up new possibilities in the handling of liquids and gases, enabling processes to be designed more efficiently and flexibly. With the electrical functionalization of our metal foams (foamet® heatAirEC), we are revolutionizing heating with electricity, which not only saves you money but also makes a valuable contribution to the decarbonization of industrial processes. In the field of mechanical engineering and protection, we develop solutions for weight reduction. By using composites made from hollow spheres, we combine safety with agility.

We want to support our customers in their respective fields of application and help them compete internationally in the future with our innovative products.

Karina Kunz, PhD

Product Engineer Metal Foams

With precision in the laboratory, she develops the foams of your dreams and the material of the future. She is responsible for smooth processes, four technicians, first-class production recipes for the laboratory, and, at team events, also for everyone’s stomachs.

Frank Reining

Application Engineer Process Development

As the person responsible for developing high-precision hollow spheres, he brings exceptional expertise, attention to detail, and passion to every project. Being an expert in processes and optimization, he enjoys tinkering with technical procedures just as much as he does with his bikes — to get perfect results in the lab and with the products.

Vit Englis

EHS and Product Manager for Ceramic Hollow Spheres

The focused and meticulous chemist — responsible for EHS and the product development of ceramic hollow spheres. Minimalistic, independent, and solution-oriented, he applies his expertise with precision and ensures efficient processes that run smoothly.

Michel Wolf

Technician

The problem solver with drive, engineering DNA, gasoline in his blood, and a knack for complex tasks. Find a solution for every tricky problem and implement it.

Albert Holz

Technician

With an eye for detail — whether in CAD drawings, at the sintering furnace, or on the movie screen. As a cineaste and all-round knowledge buddy, he brings creative perspectives to the team, ensuring a balance between precision and passion.

Philipp Richter

Technician

From the oven to the laboratory: our technician with a passion for baking, green fingers, and an unwavering knack for finding clever solutions — always there when the team needs him.

Daniel Vizler

Technician

Ensures strong performance in the laboratory and at the gym. With energy, charm, and team spirit, he keeps more than just the machines running smoothly. Even in tricky situations, he keeps the mood in the team over the top.

Our Mission

At hollomet GmbH, we develop and manufacture innovative material solutions that combine functionality, efficiency, and sustainability. Through the targeted use of cellular metals, hollow spheres, and foam structures, we create products that reduce weight, save energy, and improve processes — for a more efficient and environmentally friendly industry.

With our expertise in powder metallurgical processes and our commitment to the highest quality, we support our customers from the initial idea through to implementation. Our goal is to work together to develop solutions that push technological boundaries and pave the way for a sustainable future.
