Surface engineering for injection moulds

The nanometre makes all the difference.

Robotic polishing reduces roughness and creates defined visual and functional surfaces. Nanostructuring and functional coatings complement the surface – tailored to your application.

Visual and functional surfaces

Repeatable quality.

Defined gloss and uniform surfaces for demanding tooling applications. Polishing is a service in its own right and can also provide the basis for further surface treatments.

03The 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.

04Contact 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.

05Functional 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.
