The backbone of the nDurance process consist of three different protective layers, each contributing to making your crane highly resistant to corrosion and the hardwearing environments that it is exposed to every day. Below the process is described step-by-step.
After thorough cleansing, degreasing and blasting of the metal parts, the first anti-corrosion layer is applied. This is conducted in a dip tank, creating an ultra thin, crome-free, nano-ceramic shield that protects all surface areas, including cavities and areas that are usually difficult to access. The nano-ceramic shield occurs when hydroxyl groups react with each other on atom level to form a dense, cross-linked molecular network bound to the metal surface. This solid layer gives excellent corrosion resistance, and also work as foundation for the second protective layer.
Lacquer polymer e-coating
Step two in the nDurance process is the application of the lacquer polymer coating using the latest technology in e-coating. The electrified paint bath makes the primer particles stick effectively to the nano-ceramic shield, ensuring improved corrosion resistance. The technique leaves no drip or sag marks and also increases film-thickness on edges with up to 100 % compared to standard e-coating systems.
The third step in the process is the powder coating, which is carried out in a strictly controlled environment. Most of the painting is automated, but some parts are made by hand. In the oven the powder paint turns into a hard and durable surface that features excellent protection and mechanical properties to cope in the harshest of working environments.
Quality assurance control & testing
After the completion of the nDurance process, all parts are thoroughly controlled before going into the actual manufacturing of our cranes. Following Hiab Paint Standards we periodically also run tests in an external laboratory to verify the resistance to corrosion, adherence and permeation – all to secure the quality and performance of your crane for years to come.
