Group companies, integrated.

Technologies under one roof.

Local presence.Global technology.

When steel, machining, heat treatment and additive manufacturing are with separate suppliers, each one is responsible for their output — not yours. HTS gives you one team that owns every stage.

Engineering support

Your dedicated German-speaking contact in Bavaria. Technical consultation, application support and commercial handling — without routing through a central office abroad.

Fully integrated supply chain

Steel, machining, heat treatment and additive manufacturing under one roof. One team optimises across every stage — tolerances don’t stack, accountability doesn’t disappear.

Beyond the component

Product development expertise, design guidance and onsite support included. We act as an extension of your engineering team – from first concept to production-ready component.
