DLC coating against material adhesion: Reduced adhesion. Reduced downtime. Maximum availability.

The challenge

Material build-up leads to increased wear and product defects

Unfavourable surface energy and material pairings
Metals such as aluminum, silver, gold, copper, powder or plastics tend to adhere to tool and component surfaces. This is caused by high adhesion forces, local melting or insufficiently optimized surfaces.

Loss of function and quality deviations
The adhesions change the surface, impair the geometry and disrupt the material flow. This reduces the functionality of tools and components, quality problems increase and tolerances are exceeded more frequently.

Higher cleaning and maintenance costs
Build-up leads to additional cleaning processes, tool changes and unplanned interventions. This increases wear, ties up personnel resources and reduces system availability.

Production stops and rising process costs
The risk of downtime, rejects and inefficient processes increases with every build-up. Process costs increase significantly – a critical disadvantage in automated and high-precision production environments.

Typical problem areas with Adhesion or adhesion of material to surfaces:

    • Pharmaceutical industry:
      Embossing dies & tableting tools, pistons and valves, screw conveyors, dosing units, guide elements, bearings
    • Minting industry:
      Coin dies, textured dies, plating rollers, smooth and textured rollers, embossing rollers
    • Printing industry:
      Embossing rollers for smooth and textured surfaces, rollers, system components
    • Food industry:
      Production components
    • Optics industry:
      Protection of molds, embossing tools & rollers and production components in general
    • Toolmaking:
       Pressing tools, roller burnishing tools, punching and forming tools, clamping technology & clamping systems, measuring equipment

Our solution

DLC 2.0 and PVD coating – effective protection against build-up

  • Non-stick: DLC coatings reduce the adhesion of precious and non-ferrous metals and specific plastics

  • Optimized surface topology: smooth, textured and wear-resistant layers reduce adhesion

  • Partial and precise coating: Targeted coating of specific functional surfaces

  • Chemical resistance: High resistance to process and cleaning media

Your advantages at a glance

  • Less downtime: reduced build-up reduces cleaning and maintenance costs

  • Longer tool life: less wear due to less material build-up

  • Consistent product quality: production processes run more stably and with fewer rejects

  • Reduced operating costs: fewer interruptions, lower cleaning costs and fewer spare parts

  • Higher process reliability: stable production conditions ensure quality, hygiene and compliance

  • Low process temperature: suitable for sensitive tools and components

Specific cases and success stories

Coining tools, pressing tools, tools for aluminum processing, molds

DLC coatings reliably prevent material adhesion and extend the service life of tools, systems, parts, measuring equipment and components.
