DLC & PVD coatings for the pharmaceutical industry

Problem

In pharmaceutical production, precision and purity are paramount – but this is precisely where the biggest problems arise. Build-up and wear on embossing punches and tableting tools impair shape accuracy and lead to production stops. Problems also arise in filling and dosing systems: pistons, valves and seals are subject to permanent frictional contact, which can lead to abrasion, particle formation and dosing deviations. Added to this are the strict regulatory requirements for hygiene and cleanliness, which make any form of material wear or particle formation a potential contamination risk. Maintaining smooth, wear-free and easy-to-clean surfaces is therefore crucial for stable, safe and sterile production processes.

Solution

With its laser-based PVD coating technology, ANTACON offers a reliable solution for the high demands of pharmaceutical production. The extremely smooth, low-particle and chemically inert DLC coating prevents adhesion and also reduces wear on embossing dies, tableting tools, pistons and valves, which significantly reduces the risk of contamination, abrasion and dosing deviations. Thanks to their high wear resistance and long service life, tools and system components remain permanently precise, hygienic and reliable. The coating is also easy to clean and shows excellent resistance to cleaning and disinfection media – ideal for stable, sterile and efficient production processes in the pharmaceutical industry.

Advantages of DLC and PVD coatings

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

  • Significantly reduced adhesion during embossing

  • Less friction

  • Corrosion & abrasion resistance for extreme operating conditions without coating flaking

  • Significant reduction in reworking such as repolishing

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

DLC coatings extend the service life of embossing dies and reduce build-up

    these challenges

    Can we solve

    Adhesions or signs of wear on tableting tools compromise the quality of tablets and thus their approval. Tools must be residue-free, sterile, and work with lasting precision.

    • Wear and tear

      abrasive wear, adhesive wear, wear-intensive

    • Friction

      Dry friction, mixed friction, boundary friction

    • Corrosion

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

    • Adhesion of material

      Wear of the stamp surface, loss of detail, material build-up, deposits, adhesions, contour wear

    • High operating costs

      Maintenance-intensive, cost-intensive, inefficient
