Continue where others left off
Bending is a craft and benders are real craftsmen. It takes years to learn how to bend properly. BestBend makes substantial investments in the continuous training of its employees and the development of new techniques and machines. Today the specialist from Heist-op-den-Berg promotes its technique that enables you to successfully complete complex bending jobs. The company replaces sand with liquid metal to ensure the profiles do not break during the bending process.
Bending is a very specific craft, that requires concentration and expertise as well as the newest techniques and machines. For over 42 years, BestBend has been bending aluminium profiles, beams, tubes and rails. “We started out bending crash barriers and door and window profiles. Initially we had one machine, we later added a second. Based on this expertise, we now have five machines in our production hall, for all kinds of bending jobs, from simple to more complex doors and windows, rails and curtain wall profiles, for applications in a wide range of industries”, says Managing Director Rudi Vandevoordt. “Our benders are real craftsmen, who need at least four years to learn all the tricks of their trade. We also continue where others leave off. We accept standard bending jobs, but we mainly like special projects that not every bender is capable of doing.”
Sand or liquid metal
Architects and clients always push back the boundaries, using complex structures that are often impossible to execute. BestBend wants to also offer a solution for these special projects.
“For standard bending jobs, most aluminium profiles are filled with sand. Sometimes, however, the bending work is so complex that the profiles break while being bent, when filled with sand. We have devised an alternative solution that prevents this risk. Before the aluminium process, we completely fill the aluminium profiles with liquid metal. Metal is more resilient than aluminium and does not easily break during the bending process", he explains. “We start by heating up the profiles, then we fill them with liquid metal and finally they are cooled with water so they are ready for the bending process. After the bending, they are re-heated so the metal becomes liquid again and flows out of the profiles. This liquid metal is always kept in water so it can be continually re-used. Our employees developed a unique machine for this process, with a 5-metre lead bucket and an adapted operating system.
Danzigerkade in Amsterdam is a prestigious reference
BestBend has been using the liquid metal technique for several years already for more complex bending jobs, including for prestigious projects in Amsterdam, such as Hudson Bay and various façades along Danzigerkade. The latter projects especially, which were executed in close collaboration with the façade builder Aluverre, are an excellent reference. “We started by supplying and mounting the first bent façade profiles for DK4, after which they immediately placed an order for façade profiles with straight sections for the second project, DK125”, Rudi Vandevoordt explains. “Finally, we produced exceptionally large profile structures with 11-metre long profiles and 2-metre long straight sections, for DK85, which forms one large office campus along with DK125. The process, using liquid metal as a filler, played an instrumental role in the successful completion of such a challenging job.
