Innovative coating technologies for industrial applications
The art of surface treatment and coating plays a crucial role in the finishing of moulds and tools, which are indispensable in various industries. Our wide range of processes, including chemical, galvanic, PVD/PACVD and hybrid processes, enables us to offer customised solutions for specific applications. Here are a few examples: For caps and other shapes, we develop targeted chemical coatings that not only improve the aesthetic appearance, but also ensure increased durability and functionality. Chemical processes are used in the coating of hot runners to achieve optimum heat conduction and resistance. Punching and fineblanking tools benefit from PVD/PACVD coatings, which offer improved wear resistance and cutting performance.

Coating process optimises mould cores in injection moulding
Mould cores made of copper-based materials are highly valued in mould tool construction, particularly in the production of plastic parts, due to their excellent thermal conductivity. However, users of such moulds regularly face several challenges: Firstly, the continuous use of these mould cores leads to considerable wear and tear, which shortens the service life of the tools and leads to rising costs. Secondly, maintaining dimensional accuracy is crucial for the quality of the parts produced. Inaccuracies can lead to rejects or increased reworking costs. Thirdly, good release of the plastic parts from the mould is essential to increase production efficiency and ensure the surface quality of the finished parts. These challenges require an innovative solution that minimises wear, ensures dimensional accuracy and enables efficient de-adhesion.
Specialised coating solutions
Our innovative solution for the challenges mentioned lies in the application of specialised coatings such as Bordem Cr or Planotek CNBV. Both coatings offer excellent wear and corrosion resistance, which significantly increases the service life of the mould cores.
Our BORDEM Cr coating technology combines the benefits of electroless nickel dispersion coatings with the properties of chromium to enhance the surfaces of copper-based mould cores. The BORDEM® Cr coating significantly increases the wear resistance of the mould cores, improves their dimensional stability over longer periods of time and facilitates the de-adhesion of the plastic parts.
Our Planotek CNBV coating offers a unique combination of resistance to corrosion and mechanical wear, making it particularly suitable for applications where both chemical resistance and surface hardness are important.
Technical and economic advantages in injection moulding
Our coating solutions offer numerous advantages for mould cores in injection moulding:
The coating gives the mould cores a higher surface hardness, which minimises wear and extends the service life of the mould tools. It ensures contour accuracy and improved wear resistance of the mould cores, resulting in more precise plastic parts. The smooth surface of the coated mould cores facilitates the de-adhesion of the plastic parts, accelerates production cycles and improves the surface quality of the finished parts.
Extending the service life of the mould cores and reducing rejects and rework result in significant cost savings. The improved de-adhesion leads to faster production cycles and higher utilisation of the production facilities. The longer service life and stable production conditions ensure better planning and calculation of production costs.
The ability to recondition and recoat mould cores contributes to more sustainable production and reduces the need for new purchases.
