DLC & PVD coatings for toolmaking

Problem

In modern toolmaking, precision, reliability and tool life are key success factors. However, high-quality precision tools reach their limits when machining materials such as aluminum or copper: Wear, cold welding and material build-up lead to frequent production interruptions, tool changes and increasing costs. Clamping systems also lose clamping force and accuracy over time due to friction, wear and deposits, which has a negative impact on machining tolerances. Measuring equipment and precision tools are also affected – the smallest deviations impair dimensional accuracy, process reliability and productivity. The result: higher costs, loss of quality and inefficient processes.

Solution

With its laser-based PVD coating technology, ANTACON offers a high-performance solution for the challenges of modern toolmaking. Our DLC coatings create an extremely smooth, mechanically stable and functionally hard surface that significantly reduces friction, minimizes material adhesion and effectively prevents cold welding – even when machining aluminium, copper or other non-ferrous metals. As a result, precision tools, clamping systems and measuring equipment remain permanently protected and retain their dimensional accuracy and function over long periods of time. Even high-precision components benefit from the uniform and resilient coating. The result: longer service life, stable processes and maximum precision – for greater efficiency, quality and cost-effectiveness throughout the entire production process.

Advantages of DLC and PVD coatings

  • Up to 5 times longer service life for highly stressed components

  • Abrasion resistance for extreme operating conditions, e.g. against loss of clamping force

  • Less friction

  • Significantly reduced build-up during non-ferrous metal processing

  • No delamination due to stress-free DLC coating (possible elongation up to 5 % cyclic)

  • Ideal for series production
    (from batch size 1 to medium series)

    these challenges

    Can we solve

    Tools are constantly exposed to extreme stresses. Without resistant surfaces, productivity, dimensional accuracy, and quality decline dramatically, leading to higher production costs.

    • Friction

      Dry friction, mixed friction, boundary friction

    • Wear and tear

      abrasive wear, adhesive wear, wear-intensive

    • Corrosion

      susceptible to corrosion, rust-forming, unstable, not chemically inert

    • High operating costs

      Maintenance-intensive, cost-intensive, inefficient

    • Adhesion of material

      Wear on the tool surface, loss of detail, material build-up, copper and aluminum deposits, adhesions, contour wear
