BORDEM SV: The advanced coating technology for mould cores

The BORDEM® SV coating is an innovative solution for mould tool construction, especially for the production of plastic parts with mould cores made of copper-based materials. This coating technology combines the benefits of electroless nickel dispersion coatings with the properties of chromium to enhance the surfaces of copper-based mould cores.

Properties and benefits

  • Increased wear resistance: The coating minimises wear on the mould cores, resulting in a longer tool life and reduced costs.
  • Improved dimensional accuracy: The coating ensures precise dimensional accuracy over longer periods of time, ensuring the quality of the parts produced and reducing scrap or reworking costs.
  • Easier de-adhesion: The BORDEM® SV coating facilitates the de-adhesion of the plastic parts from the mould, which increases production efficiency and improves the surface quality of the finished parts.
  • Excellent corrosion resistance: In addition to outstanding wear resistance, the coating also offers excellent corrosion resistance, making it a modern and resilient alternative to hard chrome plating.

Application area

The BORDEM® SV coating is mainly used in mould tool construction, especially in the production of plastic parts with mould cores made of copper-based materials. It is particularly suitable for applications where both high wear resistance and good corrosion resistance are required.

Summary

The BORDEM® SV coating is a specialised solution that optimises the performance and durability of mould cores in plastic injection moulding through its unique properties, thus contributing to more efficient and high-quality production. By combining electroless nickel dispersion coatings with the properties of chromium, it offers a comprehensive solution to the challenges of mould tooling.
