Surface engineering for injection moulds

The nanometre makes all the difference.

We develop surfaces that measurably influence demoulding, deposit formation and process stability – starting with your specific application.

02The surface as a process element

Surface strategy

The surface makes the difference.

Demoulding, deposit formation and wear on a mould surface

The interface between steel and plastic

More than the final machined contour.

The mould surface directly influences demoulding, deposit formation and wear at the interface between the mould and the part.

Friction, corrosion, appearance and dimensional accuracy of a mould surface

From problem to function

The application determines the strategy.

Friction, corrosion, appearance and dimensional accuracy require different properties. Plastic, geometry, tool material and production conditions are considered together.

03Contact at the nanoscale

Nanostructuring

Contact begins with the finest structure.

Contact area and adhesion with smooth and adapted nanostructures

No added coating

Precisely adapt the topography.

An adapted micro- and nanotopography reduces the effective contact area and influences adhesion and demoulding – without adding a coating or changing the part geometry.

Measurable influence of nanostructure on demoulding force

Making the effect visible

Less contact. Less force.

In the measurement comparison shown, nanostructure 10L requires up to 50% less demoulding force for PP than a high-gloss polished surface. 3D topography and microscopy make the effect visible.

04Functional coating

A system of structure and coating

Precisely tailor the function.

Surface toolkit with base treatment, diffusion zone, interlayer and functional layer

Modular toolkit

Think of treatments as a system.

Base treatment, diffusion zone, interlayer and functional layer form an application-specific toolkit. Depending on the task, a single step may suffice, or a coordinated process chain can be used.

Functional coating for demoulding, deposit formation, friction and resistance

The effect in the process

From demoulding to resistance.

The desired function takes priority: less adhesion, fewer deposits, defined friction behaviour and greater chemical or thermal resistance. CrN and DLC are possible components, rather than the starting point for selection.

From surface to solution

Which surface does your process need?

Plastic, mould, geometry and process requirements determine the right nanostructure, functional coating or combination of treatments. Explore the individual processes and how they work together for your application.

Technical expertise that delivers in production

From a specific problem to a fitting solution.

Gloss & Coating combines locally produced surface treatments with expert advice and continuous development. The aim is improved mould performance that reduces scrap during start-up and series production while conserving resources.
