Engineered for Performance. Built for Series Production.

The Load Carriers within the System.

Outstanding

Precision and Strength

Our cold forming process uses targeted work hardening to increase material strength directly within the grain structure -controlled, durable, resilient.

The result: dimensionally stable geometries with consistently tight tolerances - even across long production runs.
Reliable

Series Performance at Scale

When every cycle counts and no deviation is acceptable, process stability becomes decisive.

Our cold extruded parts deliver what modern mass production demands: millions of identical components with consistently tight tolerances - process-safe, low-wear, reliable.

Short cycle times, high output and reproducible quality turn volume into efficiency - and efficiency into competitive advantage.

Because demanding quantities are not a stress test for us.
They are standard.
Unbeatable

Material Efficiency

What alternative processes lose as scrap remains in the component.

Cold forming utilises the material almost completely: forming instead of removing, shaping instead of wasting.

This reduces material costs, conserves resources and improves the carbon footprint — without compromising dimensional accuracy or performance.

For those who don’t just calculate efficiency - but realise it.

Our Answer to Technical Details That Must Deliver:

Cold-Formed Sleeves & Bushings - Customised, Economical, Engineered to Fit

They may be barely visible — but they determine how the entire system performs.

Our sleeves and bushings ensure precise fit, reliable function and smooth system performance.
Whether a spacer sleeve in a vehicle structure absorbs several tonnes of load at specific points, or a sensor bushing guides a component to within hundredths of a millimetre — details like these define quality, safety and readiness for series production.

We manufacture exactly these components — millions of them — precisely and reliably.

What you see here is just a selection. No two components are the same — which is why we develop the right solution for your specific application.

Already know what you need? Perfect.

Not quite sure yet? Even better.

Let’s think ahead together — and develop it.

Because our focus is always on delivering the perfect customised component .

Support Sleeves - When Stability Is Non-Negotiable

High loads. Tight tolerances. Installation space under pressure. When structures require targeted reinforcement and deformation must be prevented, our support sleeves deliver what other components cannot. Engineered for peak technical loads, precisely dimensioned and series-proven, they provide structural integrity where it matters most -economically scalable and reliably reproducible.

Spacer Sleeves - When Every Millimetre Counts

They define precise distances, relieve structural stress and enable functionally reliable assemblies - even under dynamic loads. Our spacer sleeves ensure maximum dimensional accuracy, reduce system stress and protect against premature wear. Whether in chassis systems, housings or mechatronic assemblies, we deliver solutions that withstand high loads and create measurable value in series production.

Bearing Bushings - When Rotation Must Last

Where motion meets load, standard solutions are not enough. It takes experience, material expertise and a deep understanding of long-term performance. Our bearing bushes minimise friction, protect against wear and safeguard the system performance of your assembly over its entire life cycle. With optimised friction coefficients, optional dry lubrication and maintenance-friendly series design, they reliably withstand continuous loads and changing load profiles - permanently and cost-effectively.

Collar Bushings – When Support Means Structural Control

Collar bushes do more than provide guidance. They secure components axially, absorb radial forces and create defined load paths where movement, precision and structural stability must interact flawlessly. Engineered for high loads and demanding series production, our flanged bushes combine dimensional accuracy, load-bearing strength and economic scalability. Precisely manufactured and series-proven, they deliver consistent performance under continuous stress. Where precision is not optional - but essential.

Understand Design. Engineer Function. Think in Systems

Sleeves & Bushings in System Design - Differentiated Engineering. Targeted Application.

Kaltfließgepresste Bundhülse für Schließsysteme im Automotive-Bereich | MN Kaltformteile

Functional Connections. Precisely Defined.

Small components. System-critical impact. Sleeves and bushings define how forces flow, how movement is guided and how assemblies remain dimensionally stable under real operating conditions. They are not accessories. They are functional interfaces that determine whether a system performs - or fails.

What Unites Them

Their value does not lie in shape alone, but in how they respond to stress, tolerance chains and dynamic forces. We analyse the application, define the load case and engineer the geometry accordingly - transforming technical requirements into reliable, series-ready performance. That is not mere manufacturing. That is engineered performance.

Sleeves – Cylindrical. Load-Bearing. Structurally Defining.

Sleeves are rotationally symmetrical hollow bodies with a continuous cylindrical geometry. They are used to secure positions, define spacing, reinforce structures or serve as load-bearing connecting elements. With a defined wall thickness typically ranging from 1.5 to 2 mm and a precisely specified internal contour, they ensure controlled and even distribution of load forces.

Bushings – Integrated. Guiding. System-Stabilising.

Bushings have functionally integrated geometries: Features such as a centre collar, collar or defined press-fit dimension enable additional stop, bearing or fixing functions. They guide moving components, minimise friction, compensate for axial and radial tolerances - and ensure even force distribution in the system.

Where They Prove Themselves

From flexibly coupled assemblies to high-precision bearing points in mechatronic systems - wherever axial and radial loads combine within tight installation spaces. Collar bushes are often overmoulded with plastic to ensure secure anchoring and defined axial retention. This creates a stable mechanical interface that integrates reliably into the surrounding assembly while maintaining dimensional control under load. Where movement, force transmission and positioning accuracy must interact flawlessly, these components prove their value - not in isolation, but as decisive elements within the overall system.

Your Requirement. Our Responsibility.

These geometries are proven millions of times in series production. Every application is engineered for its specific load case, installation environment and lifecycle expectation. Performance is measured in stability under load. And in consistency across every cycle.

We Connect What Belongs Together.

Technology Meets Function. Expertise Meets Application. True Partnership - on Equal Terms
